Chevy 350 Build!

ok cool thanks, its a 2 piece seal.

Well I know it is possible to replace the seal while in the car but my personal advice would be to pull the engine if it is indeed the seal. I don't like working under a car on my back when replacing something in the bottom end.

yeah I got the long weekend so im pulling it now. I can just loosen the caps and tap the bottom seal around and off right? I dont need to remove the crank

so I removed the headers to get then engine out again and notice on cylinder number 6 and 7, there was alot of oil coming out of the exhaust port. The header had a coat of oil all over, but only on those 2, did I mess up the valve adjustment on those ones?

Check the valve guides on those cylinders. They may be eccesssively worn. Are the valve seals still there? They may be ruined.

 

[snowmangaggift]

The heads are almost brand new, only 6000 km on them when I got them.

 

[CHRIS.O]

If oil did get into the exhaust port the only way I can think of that it would have gotten there would be through the valve guide or valve seal. So ya, agree with othtim.

Having some troubles getting this thing running.. It starts up no problem but today after about 2 mins of total running time i got this terrible screeching noise. and my lack of experience doesnt help. Does anyone know what this might be? im worried i messed something up during the build and now something is rubbing. heres a video:

would a worn valve guide cause a misfire?

No, what makes you think it has a misfire?
