oil leak on sr20!! where is it coming from?!? - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

I have a redtop sr20 and its been leaking oil alot lately. I check the oil pan, the oil filter, my oil pressure sensor outlet, and valve covers and i dont see any leaks anywhere. However, after driving my car hard a bit for a few days, i would see droplets of oil clinging to my oil pan and my front sway bar dripping with oil as well. I dont know where the oil is coming from. I THINK it might be the crankshaft seal leaking but i dont know for sure. anyone have any ideas?? (

Depending on how clean you keep your engine , it should be somewhat easy to determine where its coming from , Could just be misting and building up and slowly creating a leak. Really need more info to help determine what area it is coming from , again which a clean engine you should be able to find out at least what region it is coming from.

I had oil on my sway bar when my front seal was bad. pulley was slinging it. use a mirror and flashlight and peak behind crank pulley

I had a bad front main seal and it was slinging oil on my sway bar, upper radiator hose and on my hood, lol. Basically anywhere in the rotational plane of the pulley.
