2 Very Small Oil Leaks

I keep the bottom of my engine spotless, so I can stay on top of any leak as soon as it starts.

Well, I've just had 2 separate leaks begin here recently.

1. Is at the union between the turbo scavenge pump and the cam housing

2. Is at the union between the engine oil cooler and the engine block

The leaks are both so minor, that hardly a drop of oil hits the floor, but I can definitely see the oil residue...

For the first leak, I see Part 930-105-197-05-M17 [Cam end plate gasket]. When I remove this pump, should I look at rebuilding it? I didn't see any posts regarding this...

For the second leak, I see Parts 999-704-173-50-M213 and [2] 999-704-172-50-M213 [Oil cooler seals]. Do these seals go bad? And, how hard is it to get the cooler out of there and replace them? Should I be looking at anything else regarding this?

Thanks, Shannon

I picked up a small dripper this summer as well. Pissed me off, but these cars don't go leak free forever (mine is most likely the lower left valve cover gasket...time to adjust the valves anyway).

I think a person can remove the oil cooler without too much difficulty, though I've never done it with the engine in the car. I replaced mine as a matter of course last time she was out'a there.
As far as the turbo oil pump....well, I have no idea so am all ears on this one!

Here's a pic of the oil pump leak. The banjo bolt is not leaking at all...

Shannon, I just fixed the same leak on my 86. No need to rebuild the pump. I just pulled out the old seal and replaced it with a new one. If I remember correctly I also replaced the scavenge pump shaft gasket. No more drips. Jeff

I did both with engine in the car, the scavenger rubber o ring was bad, replaced it after i reinstalled the engine. i did not know it was leaking in the first place. I pulled the oil cooler also. All require a partial engine drop. alot to get to.

The joint where the oil droplet is sitting in your picture is actually dry. No oil runs throughout there. So you know it is not leaking from there. It's either to the right (in your picture) between the base of that aluminum and the cam housing or where the oil pump shaft comes through the housing. As far as rebuilding the pump, the only easily serviced part in that pump is the rubber o-ring as DHG said above. I would bet on the cam housing, triangular shaped gasket that goes behind that pump bracket. From the picture it seems like you already know that all you need to do is pull off the rear wheel and you have easy access. Pull the lines off first or you will fight with them for 15 minutes while jiggling the pump bracket around until you figure out that you have to put the housing back on to get the torque you need to get the lines off (please don't ask how I know that).

So, I really need to drop the engine [partially]? Was hoping no engine drop necessary...

These may help.

Some pics for reference. There is a paper gasket that goes on the end of the cam before the smog pump drive goes on which has a tendency to leak as well. Figured it couldn't hurt to post some pics for you.

Best of luck,
Bryan
