JaredA Posted December 18, 2025 Posted December 18, 2025 Have no idea what this is, bearing? Connector rod? Cam sensors? This is my second engine in this car to have major issues. Any help would be lovely. 2004 350z Listen to the problem here Bottom of trans looks slightly wet also, and major oil leaks under the engine as well, engine oil pan is wet. Quote
ZMANALEX Posted Monday at 15:51 Posted Monday at 15:51 Could be numerous issues. Does the knock increase in line with increasing the revs? Is the oil level at maximum on the dipstick? How is your oil pressure? Sump pan oil leak is a cheap and easy fix, link is below. The oil on the gearbox will probably be oil getting blown back from your sump leak. Quote
