I almost forgot how much fun it is to drive this car. Actually even more fun with the V8!
Unfortunately there is still the issue that during cold start the oil light stays on for too long along with some valve train noise. I was really hoping that it was caused by the engine has been sitting for the most part of 18+ months.
I looked all over FABO for causes. After it was sitting while I fixed the transmission leak, I checked the oil level and it was too high. I wasn't sure how that could have happened, but I drained the oil to the right level on the dipstick. The dipstick is still really hard to read, but I thought I might have misread it. Anyways, when the rough starting continued, I decided to drain the oil again. I thought that possibly there could have been gas seeping into the oil (I read that here on FABO), so I changed the fuel pump because it was easy and cheap enough to do. I also thought that the oil filter could have been clogged, so I changed that too. I filled the engine with 10W30 oil +STP oil treatment (that has the ZDDP) for a total of 5 quarts. The I ran the engine and let it sit over night and then marked the dipstick where the level was (I also read that here on FABO):
As you can see the new full mark is quite a bit higher. Anyways, none of this changed anything:
How bad is it to drive the car like that? Once it's warm it doesn't happen, only when it's been sitting for some hours.
At this point I believe that either the oil pick-up is clogged or the oil pump is bad. When I put the oil pump and pick-up back on after painting the engine I was in a hurry and maybe made a mistake there? What else can it be?
I already somewhat anticipate that I have to take the pan off to see what's going on. I think I saw somewhere that you can take off the oil pan without pulling the engine?!
