Oil Leak - Ideas?

Pictured is a Jasper reman. Head gasket failure, preceeding head failure, allowing coolant contamination of the oil, ending in extreme bottom end wear. She was knocking like a bill collector.

Does the 4.2 eat head gaskets as fast as the 3.8?

So the answer is yes.

Sorry for hijacking.

Hey, does the steering coupler shaft need to be pulled in order to get this motor out??

Shouldn't, but it may be helpful to take the exhaust manifold out on that side.  You don't even have to do THAT, but if you were concerned about space, it would help you get the space you're looking for.  Imagine creating a spherical "gap" around the engine (to the extent possible).

Pics of the leaking engine.  This is looking up at the driver side of block from underneath.

This pict with stabilizer bar covered in oil, suggest front main seal leaking... Balancer slings it off while engine is running...

Thanks.  Everything is wet!  The front cover is soaked with oil so i cant be sure if these lower items are the source. The active dripping occurs in the bck of fhe engine on passenger side of the rear face of block.  My best guess is that head gaskets are doing it and oil runs down side of block.

If i pull this motor, whats best plan?  Are newer version of this motor useable in his car?  If not, is a newer short block useable with the old style heads and intake?  How hard is it to put a 5.0 in wth retrofitting and misc parts?  Would it bolt to my 3 speed?

A head gasket almost never leaks oil, I'd keep looking... As already mentioned you should clean the wet areas and then watch for a origination point...

As far as swap if you aren't versed in such, forget it... The transmission is about the only thing that will bolt up, linkages, brackets, wiring(incl computer), hoses, exhaust, etc, etc, etc all will have to changed/modified...

A 3.8L headgasket almost never leaks oil.  Lots of puppies cars (especially Subaru) have external oil leaks from the HG, oh, and the big Neon recall Chrysler had.

I dont argue this, but I am not sure what else could be seeping down the back of the motor.  The intake seal in the back is slightly wet, but not the cause of active dripping.  Curiousity is getting the best of me, and I think I am going to pull the motor so I can see definitively where this was from, and also be able to replace all from the top down.

Unless someone here is interested in a rust free 84 body for $1000.

Rear intake seal. Rear main seal. That's about it.

Yes.  Perhaps the rear intake is seeping from a corner that I cant see.  The rear main could be leaking, but its not whats causing oil to seep down the from the starter mounting surface right?  Would be more right where crank is on back of motor correct?
