the white smoke...

Ok so I don't have a bhg. I got it checked by a reputable shop and it turns out the reason the smoke looks white is because I'm using synthetic, i've ONLY used synthetic since I've got the car. The mechanic checked it by smelling it, he actually stuck his nose in the tailpipe while it was running smelled the smoke and he said it was burning oil. More then likely caused by valve seals going bad. This would explain why the car doesn't overheat and I don't have exhaust gas in the coolant, because it's not a bhg. Also why there is no coolant leaking in the oil, because nothing under the cap and the oil itself is not milkshake but just plain ole oil. So white smoke CAN be oil. Although I guess mine was sort of light grayish white, but still white nontheless.

The mechanic also said that if I wasn't using synthetic I probably would have been pouring out much more white smoke then I currently am, but he said it would be ok to drive it as long as I keep an eye on the oil level and try keeping the plugs clean and/or changing them more often until I got the head worked for the valves, which makes sense. Because apart from the short amount of time it smokes when idling for like 5 seconds during a warm startup, it run perfectly fine.

It's also been suggested to me that an oil gally accessible through the valve covers might be blocked possibly causing excess oil to build up in the valve covers... maybe backing up the pcv to spit oil into the intake charge? Sounds possible doesn't it? I think that's what I'm going to check next. What do you guys think? Do our cars carry pcv valves? I've looked everywhere and it just seems like we have that little hose, no actual valve to prevent oil from possibly seeping up there...

I should think that synthetic even though it is synthetic would still burn blue because it is still oil.

The drain holes in the head just under the valve covers are huge man, you'd have to have a shitload of sludge built up in order to clog them.

We don't have a pcv in the normal sense, That metal pipe that connects both valve covers to the tb is what does it for us.

Get a tsrm so you can research all you are asking:icon_bigg . there is a pcv thread that I just started and will help you a bit. But with the tsrm, it was tough to find. But it is in there. We don't have pcv valves, we have pcv lines. The pcv lines are the lines connected to the top of the valve covers.

Could the pcv be removed if I put a cap or something in the three spots the hose runs to? aka, the two valve covers and the intake.

Yeah, but you'll really screw up your motor even more. At most I'd get a catch can and run the lines into the can and dump the can when it gets full.

Ok won't do that then, I just wish I could redirect it into something else. I've seen pictures of other people's cars and it looks like quite a few people direct the pcv tubes into something other then the intake manifold... doesn't that just sound like a stupid thing to do in the first place. Put a line that provides crankcase ventilation for hot oil fumes past any sort of filter/breather and directly into the intake... wtf? I mean at least my old crownvic had a valve to prevent excess oil from travelling upwards and even before it got any further it had to go through the fucking pcv breather AND the air filter before it got into the air charge. Does anyone know why the toyota gods of engineering found this acceptable?
