alxns7 Posted October 19, 2016 Share Posted October 19, 2016 (edited) Ok so I'm not sure whether I have a problem yet but this might be interesting for some. Ever since I got my EU spec there's been a few oil leaks everywhere around the engine, and intermittent oil smoke coming out of the exhaust (occasionally a LOT). I've always thought it was due to tired turbo or valve seals, until recently when I started reading about crankcase ventilation on the 2JZ. It all made sense and I decided to check the PCV valve. Of course the grommet around the valve wouldn't budge (hard as plastic) and it broke to go inside the cam cover. Now, I'm not sure if the PCV valve really was faulty but I decided to buy a new one anyway. In the end I replaced the PCV valve, the grommet, one of the ventilation line between the two cam covers, as well as the oil cap seal. Also, during the operation I noticed that almost all my cam cover screws were loose, so I torqued them all back to 6 Nm. First of all, it seems to have fixed the intermittent oil burning problem. Now it will just smoke a little when at high vacuum (coming at a roundabout) or at idle time to time but this is probably due to oil remains in the intake from before. But more importantly, the car will now hit 1-1.05 bar against 0.85-0.90 bar before (it's just on wastegate spring pressure for now) Does that make sense? I'm not sure. But the bottom line is, check your cam cover screws and PCV system ! Easy and cheap fix for a healthy engine. The only problem I have now is the fuel cut. Though it's cool throwing a flame time to time Edited October 19, 2016 by alxns7 (see edit history) Quote Link to comment Share on other sites More sharing options...
