Hello,
I recently have BMW e30 325, I got the tune down and I've got it running pretty strong, pushing around 10 psi. I installed the EEII USA kit. I have the exhaust all done and the intercooler piping all dialed in.
The biggest problem has been oil leaks. Pre-turbo it would leak little to no oil. Now, it will leak oil all over the place when shutting the car off (It drips a little bit, but from all sorts of different spots). The oil feed and oil drain lines and fittings aren't leaking any oil. I also replaced the valve cover gasket and it still leaks oil
Here's the big problem, I think there is something wrong with the crankcase ventilation. It leaks oil out of the valve cover cap (Which I now replaced) and all over the valve cover. So, I think this is a big clue. How does crankcase ventilation work on the '86 E30?
In the kit it came with an oil catch can (this kit didn't come with any instructions). I never installed it, didn't think I would need it but it is looking like I might. Where would I hook that up to? Do I run it through that hose that routes back to the intake (Off the ICV i believe)?
Also, my oil level is pretty full (shows a little bit below max on the dipstick), for a couple of reasons mostly just because it leaks oil.
Currently, it runs 10W-30 oil. I have considered moving up to a 15W-50 to thicken the oil because of all of the added heat. Is that something I should do?
