My recently purchased Roadster

[inex01]

My recently purchased Roadster that was a "Show Car" was lacking power, well over this weekend it blew a head gasket and now I know why. Every single exhaust valve was burnt, intakes were 50/50. So now I am in process of doing the valve job. Check out these pictures that are attached

The deck doesn't look to good by the stud hole and #1 exhaust port either.

Yes Bob I agree, has some meat on it around the combustion chamber but sparse where the bolt by the water port is.....very iffy ! a club member has the old Ford valve seat tool and after we do the seats I am going to stick with the old style valves as he also has the tool to grind the stems. Will get her running and if she holds with no leaks will drive the wheels off till whenever, if on the other hand she does not well then a new engine will be the fix. Anyway having a good time believe it or not, Oh also the head was cracked in cylinder # 4, just got a call from my machine shop.... in other words the engine was real sick.....

Yeah, those valves weren't sealing too good!

It would be best to have the block decked but it would be much more involved. A two part epoxy could be used to level up the bad spot at the water port and a composit B head gasket may have the best chance of sealing on the pitted surfaces.

Yes Purdy, we do plan to follow your suggestions to the "T", it may or may not work but definitely worth a try, like I mentioned if all fails a new engine will be installed over this coming winter. Word of warning to all.... if it is a show car you are looking at do a very careful inspection of the drive train.... I sure did not !

Did it actually run when you got it? The compression would be horrible.

Hey Chuck,
Regardless of which head gasket you use, I'd be sure to spray copper coat on BOTH sides and then use a brush to coat around each hole. You are going to need all the help that you can get to seal compression against that block surface...good luck

Will do and agreed will need as much help as possible with this little banger, and Russ asked if she ran, well she did ? was quiet as a mouse most likely because the valve clearance was basically zero because of wear, and I did check compression when I got her and all cylinders "Believe it or not" were at 50 + or - 3 so I knew she was not very healthy but never would I believe it to be in this condition.

They are indeed forgiving old engines.

I always use new exhaust valves when I do an engine, intake valves run much cooler but you need all the margin you can get with exhaust valves. I really do recommend the Fel-Pro brand of head gaskets, they have silicone rings around all the bolt holes ....to prevent leaks.

Hi Joel, just picked up the head gasket at Brattons and is exactly that the 8080 that has high temp silicone, boy you guys on this site are really right on ! really appreciate all your guys. no kidding!
