Hey guys, need some G thoughts on this. My 05 g35 coupe started leaking oil after taking out my catch can which wasn't really doing it's job. In the last 3 wks. I've added 10 qts. I've already had the valve covers changed at 97k. Car currently has 156k. I've had it on the lift and between 4 other sets of eyes cannot see where it's coming from except that maybe above the alternator. The oil when driving seems to travel to the front and all over the timing cover, pulleys, belts then down under to the rack and pinion, axle ant the entire undercarriage. Half way down the evap line the oil starts.. I've checked plug #3, but clear, doesn't mean that it isn't one of the other ones. Anyone else have had the covers re-warp? Really need some input, Nissan wants $195 to just look at it for an hr. lol Thank you all.

 

damn wat a mess. id clean it up and inspect from there after driving it for a bit. should be easier to locate the origin

 

had the same problem with my revup.. couldn't locate the leak myself so i replaced all oil rubber sealants, O ring.. valve cover gasket.. they were selling them on ebay as a set back in 2011

 

+1 on what he said

That would be the only way to find the source

 

Kinda looks like your front main crank shaft seal is bad.
