Default Nightmare Engine Rebuild

Thanks for everything, this is an amazing site,, wish I would have found it sooner than I did, would have saved me a ton of grief,,my wife now thinks that I live on fordbarn! And ford garage!
I have a question for all you smart experienced folks on here.
I purchased a nice barn car, 30 Tudor the engine was good, original numbers, just no shims left in any bearings, so since I don’t pour babbit I took it to some one that claims to have done hundreds, just to freshen it up, I let the pro do his stuff, all the other A guys use him,,it had all the valve seats replaced, new Babbitt, ground crank, rods,,ect.
When I picked up the engine it had been painted inside and out with cast iron color paint on top of old sludge and dirt. The crank didn’t feel right, it ended up being 4.5 thou. Off center on the center main with 5 thou shims added so it would turn.(I didn’t want it turned to begin with it was standard and in good shape but it got turned anyway)
The rods were 20 grams out from each other and the wrist pins were looser that they were at the start. None of the caps were original to the block or rods,,they were matched when I brought it in. The new cam-crank gear had been beaten on cold and was well deformed and the edges of the teeth rolled.I tried to very calmly talk about some things that I could see and got my butt chewed real good and told that that was good enough for a model A, I never do work like that and it is not good enough for me.
I’m not interested in bad mouthing anyone in public, but this is only to establish a baseline for my question.
For interest I will ad that I started turning bolts at about age 12, was very serious by 16,(built my first engine tranny and rear end) and did it for a lively hood for many years, everything from bumper to bumper, specializing in auto transmissions, engines and anything else. I have a reputation for excellent work, I am a perfectionist, I now make violins, very nice ones according to professional players, I don’t say any of this to boast, I’m just a plain ol half dumb guy who’s not afraid to try and, so now you know where I am coming from. I learned to drive in a 28 Tudor,I always wanted one and after all these years this is MY CAR FOR ME The entire car is apart from bumper to bumper, and every bearing and clip that is needed will be.
I thought that I had seen it all! But when I got this engine back I was in shock! Seriously, as in no comprehendo!
I was SO STUPID for letting him tell me that the seats are always changed in a model a,,what a fool I can be. After reading on here,,about the seats I feel like a total idiot, and I am ashamed to say that I bet I could have gotten 40,000 miles out of the valves the way they were.
So now I have a Burlington crank , new rods,with inserts. (the new babbit broke out like glass into tiny pieces) I have taken a brass punch and tapped lightly around on the seats and they did settle some more, barely, barely,,,,, but they did move. Funny thing they look beautiful. I am a perfectionist and after the other work I cannot rest that they are not too tight or too loose or might have a piece of iron under the seats to rock on and get loose. I feel like I have been in a nightmare.
So for and experiment and a baseline,,,I took the original head and peened around a bolt hole on the top, and put a socket in the hole from underneath and drove it through to test the malleability and strength of the peened cast, and I really had to drive the socket past the peening and the cast did not even chip out as the socket pushed through. That is some tough cast iron.
So my question is do I pull out the seats check the fit and roll the edge and put them back in and peen,,, or do I drive across the USA with a knot in my stomach always wondering?
Is the block iron the same as the head, will it peen the same?
If this was your car,,,what would you do?
Thanks for everything, this is an amazing site,, wish I would have found it sooner than I did, would have saved me a ton of grief,,my wife now thinks that I live on fordbarn! And ford garage!


Thanks
Still Queezie

I am sorry this happened to you.

If it were mine, I would find a reputable shop and have it redone. Yes, it will be expensive. However, it beats always wondering how far you will make it this time.

A Model A motor is surprisingly precise under all that cast iron. When Turlock Machine (or another reputable shop that specializes in Model A motor rebuilding) gets done with a Model A motor, the tolerances are exact, and you don't have to worry about it coming apart on you.

I had a similar experience with a transmission of a different brand pickup. Took it to a vendor that was supposed to be the experts on transmissions of that era. Yeah the recommendation was from one guy that was recommended by another guy. I would have done the work myself had I been able to locate the parts at the time. It was a nightmare to say the least and after weeks of waiting and finally getting them to stop telling me lies i was able to find parts at the other end of the USA NOS and led the rebuilder to them. Enough of that. So from that experience I now only use nationally advertising vendors and recommendations from reliable sources. I trust most of the posters here at Ford Barn if or when they say don't use them or yes they are dependable.

I too have learned something about Model A valve seats and when I rebuilt my engine thought at the time to myself this must be some tough block if it were built without replaceable seats. None were burnt or pitted and I just figured lap the new updated valves and give it a try. So far after at least 500 miles I have good exactly the same compression in all 4 cylinders.

I would get your engine to a reputable vendor and have it fixed. After your experience about this guy I wouldn't be one bit shy about asking several vendors names, some you have read about and throw the guy you used in there. Bad experiences need to be shared as well quality workmanship from vendors that know they must do quality work if they are going to stay in business.

Posting pictures to show help. Add a location to your profile you are in so other people can help you find vendors nearby.

I guess I am now concerned about the thickness of the cast under the seat and how tight they are. These are 3/32 seats and are small so I am considering pulling them out and checking for debris, the fit, then rolling the edge and peening them in.
I have done many valve jobs but at this point don't want any more surprises,
the place that will line bore the block will do the seats again, but only by making them larger.
To me that is out of the question if there is any other way.(I've been reading too much fordbarn,is that possible!)
I can make a tool that will pull them straight up and out then reinstall and peen.
I am confident that I can pull that off. And the question of valve seat adhesive, can it later deteriorate and leave things loose. And exactly what brand,,, many shops don't use any.

Am I out of my mind or what! Don't ask the wife!

Your description of the attitude and comments from this so-called engine builder had me grinding my molars. I once had a similar exchange with a guy who was regarded as an expert on antique engines and managed to extricate my engine from his shop before he got too far into it. When the guy gets testy about your questions, tells you he won't reveal the source or type of Babbitt he uses, states that his work is "good enough for an old Model A", scoffs at your suggestions, etc., then its time to grab your stuff and get the hell out of there.

Sounds like you met the same guy,,
I do most everything,,But I don't pour babbit, I thought it would work out, it did not. I saw all of these signs you mentioned before hand,,I should be horse whipped for my own comfort, I would feel much better.
I am now going with inserts,

It might help if you were to add your location to your avatar. That way some one might be able to recommend help in that vicinity. Just a thought. Sorry about your misfortune.

If you pull these out, you will never get them to go back in and stay. If you are worried about them coming out now, I grant you they will if you try to re-use them. I never replace the seats and don't ever recommend that they are unless I can't talk the customer out of it or the original seats are just beat to death.

This is what I was looking for,,the rest of the work was so bad I just don't trust the seats, this is my baby!
Too tight things crack, too loose they come out.

Do I just run it as is or pull them out and do over.

Is the block iron the same as the head?

Should they be beveled and peened in as has been mentioned on the forum?

This time around I just want to really think about it.

I realize how foolish I was for having them replaced, I got the block's to soft for modern fuel song and dance and we don't do model a's without replacing the seats.
The original seats were just fine

These are the kind of hard stories that makes all shops look bad.
I had posted long while back about questions to ask a machine shop before handing over your engine.

Clearly if the valve seats don't look right they aren't. If you got them to move then they will come out. Yes: There is a tool that will pull them straight out. Not all machine shops have it though. You can't reuse the same seat.

Interesting part of all this is that you're willing to go back there and have it done again.
If they goofed the first time and had devil may care attitude"good enough" is never good on anything. What do you expect on getting a second time?
If they were so shoddy to paint over the grease that would cut it with me for sure.

You're not the first as we've heard your story alot over the ears we've been doing engines.
If anyone reads my post I suggest you do your diligence and see what kind of work machine shop does, what they are going to do for the money and in this case have they worked on Model A before and was it successful?

The seats actually look quite nice.
After med. tapping with a brass punch I could see a silver line out side of the seat where it had moved, barely discernible with the fingernail.
I can make a tool that will pull the seats straight out.
I would like to replace the seats without removing any more material.
I am not going back to that shop at all, will not.
They have done hundreds and are known in the area, and recommended.
Many people with A's are not mechanics per say and just don't know.
I have heard stories of bad rods and trouble on new engines but it was always the drivers and the timings fault.
I realize that it was most likely neither the driver or the timing.
I also understand that this gives a bad impression on the business,,
this is true in any endeavor. There are good and bad,,,,I've been had.
I did not bring this up to complain, I have been hesitating for a while,,,
this happened a while a go,,
I'm just looking for an education. So I'm asking experience.
I've got to move on and need some wisdom for my steps.

If you are to replace valve seats you'll need a accurate bore gauge to measure the counter bore and then after selecting right size seat you'll need to machine valve seat angles.
There is a company in Texas that will make the seat to your specifications on the outside diameter. Their name is "Tucker"
Just to give you an idea of the seat puller we use: Here it is,expanding collet style impact gun. https://www.facebook.com/newenfixedt...3056598754368/

I agree that your main babbits need to be redone. You will have nothing but problems if your crank is not the proper distance from your cam. You should have a shim pack in each main cap for future adjustment.

I see you are in Idaho. The closest person to you I know of who does main babbits is Bill Barlow. He is located in Bend Oregon (telephone # 541-389-2694). He is in his 80's and is an expert. He works with his grandson. You can call him and make an appointment. He will start work in the early a.m. and be done around noon on the same day. This makes it great if you are going to bring your block to him. He also has balanced babbit rods for sale. The last I heard, about 8 months ago, was he was still doing babbit work.

The other person who does excellent babbit work is Eric Barrett. He is located in Auburn, California (telephone # 530-863-7579). He has been highly recommended by Les Andrews. The last I heard his turn around time is about one week .

Sorry for your heartache. Hope this helps you.

Never try to use the same O.D. of valve seat that has been tried, and pulled. We have never had a seat come loose or out. You just have to know the right press clearance. I have a machine shop in Fort Dodge, Iowa do that kind of work for us, and Vern's work there is perfect, and I do know what perfect is.

Here is some of his, and our work.

From what I've seen on FB concerning engine rebuilding, I'd have to say that Herm Kohnke, James Rogers, and Ora Landis' shops put out about the best rebuilds out there.

First class all the way. Good to have guys like that around.

30Tudor. So sorry to read your horror story. It's unfortunate that shops are still doing crappy work in today's age of tooling and equipment. The turds are still around always have been and probably always will
. I know a lot of old car people have been in your situation and that's really unacceptable. The work is simple in nature and any competent shop would not knowingly turn out a job with as many problems as you have told us about. It's a shame that the proprietor of the business would allow such work out of his shop.
But that shows that he is a person who cannot be reasoned with ,so therefore you got what he shoved down your throat.
Just curious did he offer any warranties with his work or was it just take it and shut up.
Again so sorry for you headaches, try some of the guys that have been mentioned here, they would not treat you like the last guy.
The difference with the company's mentioned on the barn is they love their work,cars and the people that bring in the business to them.
Best of luck

Go to some one that knows what their doing. They can pull the seats and measure. You can buy seats that are made oversized and you can also cut down a seat that is lager to the right size.
