I can't figure out where this oil is coming from. It's NOT the feed and NOT the drain. I don't think it's leaking out of the seal behind the pulley..




Getting pissed.

Oil dye and a black light might help.

 

Yeah might be the next step. So even when oil has dried, it leaves a stain behind with the dye right?

Correct, you might want to clean the area and run the engine. You can get the oil blowing back and it makes it harder to trace.

Some examples on what to buy.

 

Almost looks like the front and middle of case is leaking. I can't remember, O ring on those 2 halves or paper gasket?

 

It's a rubber oring.. what's weird is i don't see it leaking out of the case split.

But it collects at the lowest point and drips to the ground.

All of them I've ever delt with did.

 

I would definately try resealing that drain just for giggles, and as stated a bit of oil dye. Clean it down with a can of brake cleaner, blow it off and then run it.

After seeing the case seal on my V3, i dont have much faith in it longevity wise. Very thin, and barely protrudes from the machined grove.

 

I did. Three times. Changed fittings, thread sealant, etc. Its not leaking from the fitting. Absolutely not. It's leaking from the case somewhere, and running down.

I think I've had this out several times and gone through a case of brake cleaner lol.

I *think* maybe my first -6 drain into the fp blockoff was causing back pressure and maybe it blew a seal.. ? I dunno. Annoying.

My rear main seal leaks too.. F'n old style 2pc engines. I should have build a dope LTx.

I guess I still can, technically. I've thought about yanking this motor out for my t-bucket project and doing up an LT1 for the thirdgen.

I never remembered it leaking, and i never took it apart. Might want to put another case rubber rope seal on it and run it?

 

Yeah, I may end up doing that. I'll have to see where I can order a new seal online.

I've never had it apart either.
