Hi all,
I parked up my P6 a while back due to a lot of oil coming from the rocker breather on the drivers side and valley breather. Had a mechanic do a compression test (I had asked for a leakdown test but that's a different story), and he came back with #4 and #6 a lot lower than the rest, and all quite low.
So the car has been parked up and for sale.
I've since decided not to sell it as the market just wont give what I think it's worth, so I finally got into looking at the problem. The first thing I did was my own compression test, and lo-and--behold they're all pretty even albeit a little lower than I'd like! I did do the test on a cold engine though so maybe I could get a few more PSI when she's hot - anyway...I'm starting to think oldmate who had the engine before rebuilt it as a low compression or used the wrong pistons - maybe wrong head gaskets? Anyway I digress. I removed the rocker covers to check for blockages and they're squeaky clean. My son then pointed out that a bolt retaining the rocker gear between #6 and #8 was standing proud. I mean this bold was not even threaded in. I pulled it up and there's a lot of oil through it.
So, my question is, do you think this bolt being undone has anything at all to do with oil coming from the breather (I noticed there's a lot more oil still in the head on this side than the other)? Or is it just a lucky find while I work my way down further into the engine to find the real cause?
Cheers,
Rob.
