Hey guys,
Looking for advice on a leak. Seeing if my train of thought sounds right.
Just picked this car up. PO did VCG but doesn't look like he RTV'd where he should have and it's already seeping. I plan on doing that and Vanos rebuild real soon. I've done CCV, Vanos line, and Viton OFHG so far in regards to common leaks, among other things. Cleaned everything up real well. Degreased engine, dropped skid plates and cleaned off a couple pounds of accumulated sludge and got it all looking fresh. There is currently no oil leaking down the sides of the block.
While the car was on ramps for about a week as I casually did the OFHG and CCV, I had drained the oil. I noticed it would still leak about a quarter to half dollar size drop of every few days. Most of it looked to be from the area around the bell housing and rear of oil pan. I saw drops of oil accumulated on some oil pan bolts just forward of the bell housing as well as those you access thru the bell housing. So I'm thinking oil pan or RMS.
After cleaning everything and driving the car, it's still leaking. I can already see fresh oil seeping from the passenger side of the oil pan where it meets the block, and fresh oil leaking again in the area where the bell housing meets the block. This is dripping onto the skid plate and making a mess again.
I'm leaning towards the oil pan being my main leak but I wouldn't put it past the RMS to be leaking too. I'm assuming it's the pan since it was still leaking steady after I had drained the pan but it was up on ramps. I would think with the car not running, on ramps up front, and the oil drained, the RMS would be too high up to leak. Therefore the leak would have to be back of the pan where the little bit of oil that didn't drain would sit and drip out.
The only place I haven't inspected yet is the rear of the head, but, even if it was VCG which I haven't done yet, it wouldn't actively be leaking like it was when the oil was drained and car was on ramps.
Also, PO also said he ran Mobil 5w30 High Mileage with 5k change intervals. I've switched to Mobil 0w40. Figured I'd throw that in.
What do you all think?
