I have a SBC 350 with TBI that came out of a 95 surburban that im rebuilding. I took the valve cover off and noticed a good amount of sludge build up on rockers and valve springs. What is the best way to remove the sludge with out taking it to a shop? I'm also thinking of putting new heads and camshaft what would be the best with out haveing to upgrade to fuel above 87.?
There's really no good way to remove the sludge other then having the block cleaned at a machine shop.... You can remove the stuff you see in the lifter valley, but the rest of the engine and all the oil passages are full of it, too!
I have heard that you could soak them in Kerosene that would break it loose. Would that work?
Yes, it does.... but unless you take the engine apart and have it thoroughly cleaned, it's very easy for some of those sludge pieces to accumulate in an oil passage, block it, and wipe out some bearings, or worst case, the entire engine..... Please don't ask how I learned this lesson!!!!!!!!!!!:LOL::LOL::LOL:
Yes thats my plan to take the heads and intake off to clean them just so it does not get down into the block blocking oil passages. If my block is bad ill just take it to get hot soaked and honed if needed.
Then after getting most of the big stuff off I run the parts to the car wash. Ours has the engine clean option and I blast the parts with this and get them home and blow them out with compressed air.
ok cool I didnt think of that. SO i was able to find the head casting numbers they are 14102193. Are these good heads? I read that they are just stock heads that are not good if youre going to make preformance. Are there any preformance heads that are good with TBI? I also found the intake manifold number 10166133 its also stock but is there a preformance intake manifold that I can still use a TBI on?
