Alright, on the way back from work I was just driving along and got home fine. I popped the engine bay when I got home because, I'm not going to lie, I got on it a few times..

I popped the hood and I noticed smoke coming from the upper left section of the motor. If you were standing facing the car.

Also noticed the motor was pretty damn hot, but it wasn't reading high on the temp. guage.

Maybe it's normal, I'm just worried..

I went back out like 10 minutes later and although the motor was still hot, the smoke had started to clear.

Let me know this is normal so I can stop pacing like a retard.

Maybe exhaust gasket going out?

maybe a slight oil leak.

yeah mine drips oil onto the exhaust back there too...think it's a valve cover leaking...it smeels awful and is really embarassing at long lights when smoke is coming from my engine. Looks like I'm driving a total piece of crap.

Might just be your valve cover vent? From the factory it is plumbed back into the intake. Did it come out? Or do yu have a k&N breather setup?

As said above, could be some sort of trans fluid or oil getting on the exhaust as well. Crawl under the car and look....

I have the same exact problem. I think it is oil getting to the exhaust. I had to replace my ignition coil (near the battery) because it stopped working due to oil getting to it. It all started when I switched to synthetic oil. I should've learned a lesson from my MR2, if you're gonna switch to synthetic, introduce it a little at a time til the engine gets used to it.

I think you're referring to the PCV Valve (Positive Crank Ventilation Valve) and no that wont cause this type of issue. Even running PCV valves FULLY open (which I HAVE done on purpose on my previous Supra for a time) to atmosphere will only cause vapors unless your engine has 120- compression then you will see some smoke but still nothing you will be able to notice at stop lights. The *most* common issues with the 2JZGE engines is the O ring (only a few bucks new) that hardens and goes bad around the distributor and the second is the valve cover gaskets that start leaking oil over time.

SC FAN

What was the conclusion to this? Was it the valve cover gasket or something else?

Mine went away after I replaced one of my coils. It was unburned fuel when one of the coils went out. And yeah, it did come out of the upper left of the engine, right behind where the trac system is. It smelled like burning plastic.
