The Ford Barn

Ken Arms · 07-09-2020, 12:41 PM

I'm going to replace my 59 oil pan, the one I have is sand blasted and etched. should I not paint the inside or yes? If yes what would you use? Thanks Ken

51 MERC-CT · 07-09-2020, 12:50 PM

No!

Joe Immler · 07-09-2020, 01:06 PM

I agree with 51 Merc. Absolutely NOT !!

Mart · 07-09-2020, 01:08 PM

I fitted a brand new new old stock pan to my 59A crusty flatty and took a great deal of care to take the existing paint OFF the inside of it.

DavidG · 07-09-2020, 02:47 PM

Consider Glyptal, the special paint used inside big transformers and engine blocks.

Why paint the inside ? Do you think it may rust or something ?

grumppyoldman · 07-09-2020, 05:45 PM

I'll have to go with David G. I painted an engine with it inside engine everywhere I could, including pan. If you get it de-greased correctly it will not come off. Nothing will stick to it. It is also used to paint inside electric motors. Al

Joe Immler · 07-09-2020, 06:32 PM

grumpy, will it work to paint the inside of a starter and generator?

Jim in Wisconsin · 07-09-2020, 06:50 PM

It seems to me the very best you could hope for in painting he inside of an oil pan would be that it didn't hurt anything. It isn't going to help anything and you can't see it. So why do that? I've never seen one on any kind of car with paint in there.

19Fordy · 07-09-2020, 08:51 PM

No,No,No. Don't even think about painting the inside of your oil pan.

All you need is a couple of paint specs to get into your oil system and you're done.

If you take an oil pan off of any engine you will rarely see rust unless water has gotten inside.

DavidG · 07-09-2020, 09:22 PM

Right, all those race car owners who use Glyptal inside their engine blocks, cylinder heads, and oil pans to improve engine performance couldn't possibly know what they are doing.

JSeery · 07-09-2020, 09:34 PM

I always paint the inside of the blocks. One of the reasons is it increases the rate of oil return to the oil pan.

19Fordy · 07-09-2020, 10:07 PM

I would venture to add that 99.9 % of flat head engines are not super duper high performance where the use of GLYPTAL is needed to increase the rate of oil return by a few milliseconds. However, my "built 354 hemi engine block (not the pan) is painted GLYPTAL. Sorry but, I couldn't resist the temptation to post photos.
Ok to delete, if not ok.

DavidG · 07-09-2020, 10:14 PM

No oil present in those areas, right?

tubman · 07-09-2020, 10:27 PM

Jim, That is one terrific looking engine! I don't blame you for posting those pictures here. Hell, if that were mine, I'd probably post it on the Studebaker form. I'm the guy that got away with posting a picture of a dusty old Olds Rocket on here and even go a couple of favorable comments. Of course, I may be a little prejudiced, as I have a couple of hemis of my own.

Hey Denny, we all know that the FordBarn revolves around the Flathead V/8
but i'd bet there are a few Flathead lovers that have messed with Hemi V/8
engines and others too.
Denny, as a Minnesotan, I'm sure You prolly knew Tom Hoover (Dragracer Fame).
Below is a '29 Ford Roadster I had in the late 80's with a Hoover built 392
Hemi with a 671 Huffer... It ran like a Thief in the Night...FAST.

Well, ya can't delete MY posting of this jewel! I'm pretty sure I have knowledge of where this beautiful piece of Jim Pullen handiwork is headed....'Top Secret' Guvment project, for sure. I get excited imagining what this beast would look like immersed down in the bowels of that black 19Fordy coupe. A beautiful example of an iconic piece of American folklore! DD

tubman · 07-10-2020, 06:17 AM

Lanny,

Sorry to say, I never met Tom Hoover; my drag racing days were several years before his and I was long gone when he was at his peak. You never cease to amaze me as to some of the cars you have had and the things you have done.

If I had had something like that in the "late eighties", I would have killed myself for sure. I had a "T" bucket in the '60's with a good runnin' 270 Dodge hemi that was scary fast. I can't even imagine a blown 392.......

A bones · 07-10-2020, 10:49 AM

19Fordy, Nail on the head! The return rate to the pan at high RPM is the advantage of Glyptal. I had a friend who was able to get his motor into a Dupont plant for a teflon treatment. Seemed like more about bragging rights since it did not race.

The Model T boys like Glyptal because the insides can get coated with trans band fibers, and dirt ( helps to install a screen,to slow the circulation of material ) The problem is real in a T. Passages get clogged if not addressed regularly.

Jim in Wisconsin makes a very logical point.

As to pix of Hemis... Did the engineers at Chrysler Never See An Ardun? My Hemi thrill came to me at the age of seventeen. ( '56 D500 ) You can write your own conclusion.

They both came-about in the same relative time frame. As far as 'looks-wise'......I'm sorry, but the Ardun just makes the Mopar Hemis look like an afterthought, and I love the look of a Hemi! But WTH do I know? We also can't forget that the hemi was designed as an all-inclusive powerplant package by a huge organization, whereas the Arduns were designed as an ad-on accessory by a couple of sharp brothers to help seemingly anemic and overheating flathead Ford engines performing Herculean tasks in large trucks....an expensive (albeit gorgeous) 'band-aid', if you will. The 'racer' boys finally realized their true worth. DD

A bones · 07-10-2020, 11:32 AM

Thank you, I thought Duntovs were earlier.

V8COOPMAN · 07-10-2020, 01:22 PM

Without going back and looking it up, I believe you're actually correct. I believe the Duntovs were peddling the Arduns in the LATE '40s, and of course, the first PRODUCTION hemi was '51.....RELATIVELY close. DD

I hope you didn't blast the inside of your pan. If you did, get another.

I've never painted the inside of an engine myself. If bare steel and iron lasted 70 years or so I didn't think I could improve. None of the older hi performance engines were painted inside. Ford was doing some E coated pans on engines in the 80's and have heard that some of it came off and plugged the oil pump pickup screens.

ct1932ford · 07-18-2020, 02:43 PM

This is an interesting thread for sure. Before reading it I would have said absolutely not. Now I'm not sure. I will keep watching the debate.

Many people use paint or glyptal for that reason.
On a wet sump engine it probably wouldn't show any gain on the dyno.

On a dry sump engine that runs 20 inches of vacuum in the pan, polishing all surfaces in the crankcase and valve areas will show 4 to 5 hp gain from reduced windage and better scavenging of the oil.
Using paint or glyptal might offer some advantage but you would still have the rough surface.

JSeery · 07-18-2020, 04:15 PM

I do polish down the rough surfaces. I assume there is not any major advantage to it, just what we did the in 60s and I have kept doing it.

rotorwrench · 07-19-2020, 09:42 AM

This is a question with two answers. Either do it or don't. If a person has a hobby car and runs it often, there is nothing wrong with leaving it the way it came from the factory. If you want to then do it. Most folks use it to seal castings for better run off of lubricant. On a smooth stamped steel surface, the motor oil will preserve it as long as the vehicle is used on a regular basis.

Painting something doesn't always guarantee that it won't corrode. If corrosion starts between the paint and the subsurface the the paint will start to flake off. If it is painted then it's a good idea to clean the surface well and use a conversion coating to passivate it.
