Oil Leak

[nborton]

When I had the truck at the transmission place, they said it looked like the source of my annoying oil leak was at the cab side of the engine on the bottom of the intake manifold. Does oil get up there? or is more likely valve cover gaskets?

If I have to take the intake manifold off, how much R&R is that going to take me? The leak is getting larger, but still relatively small, but I think I want to take care of it.

Would engine stop leak be a really bad idea? What about running regular oil instead of syn or maybe the blend?

Thanks guys. I'm trying to get this truck back to running good now that my wife is going back to work and I'll need a reliable daily commuter again.

Re: Oil Leak

get it fixed...all the other stuff you mentioned is for cheap car salers.
could be your oilturbo feedline, oil press. sender, or dist. gasket. or your valvecovers.
R&Ring the upper intake is about 1 hour work for an unexperienced guy.

If I were you, I'd get a small maglite and some rags, and start tearing down stuff and clean up all the excess oil. Then let it run, and find the real source for the leak. No need to change out say valve cover gaskets when its your oil pressure sending unit (FWIW, I've had oil pressure senders puke oil like you wouldn't believe before when they went bad). Accurately diagnose your problem first.

Re: Oil Leak

I agree with Adam, try to find the leak and fix it. There won't be any (oil) leak between the upper and lower intake but removing it may make finding the real leak easier. If the intake and heads have never been off I'd be inclined to suspect valve cover more than intake. FWIW My dist ran loose and never leaked. Senders can, when they fail, can pump the engine dry so check that carefully. With the wheel-wells removed you can see better.Also you can run the engine with the IC removed (just disable the pump) which may make finding the leak easier.:2cents:

It could be the oil pressure sending unit, which screw right around that area. SBC often have intake gasket leaks, so it could be that as well, I haven't noticed any SyTy with intake leak though. Valve cover could leak, but the rubber seal that they use usually doesn't leak unless inproperly installed or isn't tightened properly (usually they leak around the grommets slowly making them look ugly).

Re: Oil Leak

Get the day glow dye, and run the engine with it in. after you powerwash the area. Use castrol super clean to make it clean the get the blacklite. Ive found every leajk this way. Just be careful my project started as an oil leak 2.5 years ago.
