Secondary oil pump leak
 

A couple of days ago I noticed my car was leaking a little bit of oil, I then put the car up on the hoist to inspect it. I noticed that the secondary oil pump or commonly known as the scavenge pump was leaking. I then took the o ring off the pump, used some black gasket sealer, reset the o ring then covered it in another layer of the gasket sealer.

Now the interesting part, when I went to put the four 10mm bolts that hold the pump to the cylinder head/valve cover I noticed that the one of the bolts wasn't really getting any tighter. I took it out and saw that it looked like halfway up the bolt the threads had been stretched. So I put a new bolt in and the exact same thing happened. and now the damn thing is still leaking (less then before) however enough to piss me off :mad: !

Just wondering if anyone knows of any solutions to this problem or if anyone has had the same thing happen to them.

Thanks for all the help guys!

The oil leak was originally coming from that questionable bolt. It was wicking up the threads and leaking from under the heads and appeared to be a pump leak. These pumps simply do not leak; their profile rings seal them up well.

You'll need to restore the threads for that fastener to have any chance at sealing. There are times that a 1/4"-20 SAE bolt can be used in that one position to create a fix for this, BUT thats a hack way of doing it, even though it works well for taking the place of a stripped 6mmX1.0 fastener.

Or you can install a timesert or hell-coil to restore the threads.

The only problem with using a timesert or hell-coil to restore the threads is that you are working in a VERY restricted space. Not even sure if I would be able to get anything in there.

I will run over to the parts store and pick it up, for $25 I cant really go wrong lol.. Any other ideas anyone?

Most certainly don't want to drill into anything, any other known solutions?

I think drilling and using a thread insert is you only real option here........

There is next to no room, even with a right angled drill and short bit's i'm not sure it would fit.

Then you need to lower the engine out of the car.
