Ok so I've heard a bit about the disappearing oil syndrome with our cars. Well my car has been doing it for a little while now. It doesn't really consume any oil at regular driving. Now when I'm hitting WOT it does, and I've been told that it smokes a bit when I'm at WOT. Any ideas?

e this problem too. Some tell me the smoke is blue and some tell me its black. I've noticed alittle fuel mileage loss. I dont understand it. Could i have a bad TPS or is my motor on its way out???I have 150,000 miles. other then this the cazr runs good

sounds like your valve seal. this is common on high mileage engines. If it's smoking all the time then you can think about the piston ring(s). If your turboed, then it's probobly the turbo. If the car even starts losing oil quick and it's on the ground, check the front crank seal and your pressure sending unit. If it dies, then it's time for a swap!:)Soooo many engines to choose from. Good luck and hope this helps.

One more long shot. Replace your PCV on your valve cover. It's cheap and can cause a world of trouble if it's clogged or stuck.

i heard that if you're burning blue smoke on acceleration, your piston rings are not in the best shape...

Just so you know, the "disappearing oil syndrome" is not burning oil, but the fact that you cant put as much oil in as you should when you change your oil.

actualy its very common for high rpm driving. check the archives cause i know kojima has went over it many times. track cars will end up going though 1/2 a quart i think while racing. the oil goes in though the intake with all that breather stuff we have. dont think its any blow by or anything like that but its common.

Bingo.
It's a common problem. The engine really whips up the oil and some gets sucked into the intake.
Mike reroutes the breather lines so the line to the intake tract isn't a direct route out of the valve cover. Basically switch the outlets to the intake and the oil separator.
Blowby is also not uncommon and contributes to the problem at high rpm.
Rerouting eh? Do you think you could describe in a bit more detail on the process? TIA.
Oh and George, it's good seeing the die hard list members post on here. I know you possess a lot of knowledge, and we all appreciate the help.

all this time reading and thinking not talking out my ass on the list has sorta payed off i think :). george has been on the board for a while....just dont care to talk like most on the list. and i understand why :-D. But every now and then geo pops up.
well i am talking out my ass this time but if i read right and remember a bit what he is talking about is that one line that shoots straight out of the VC and goes into the intake. Put it into like a catch can or such before putting it back into the intake track. It has to be that way for proper pressures in the crank case, but at the same time all that oil droplets in the air need a place to condense. kinda like the black box on the front of classics, thats its function. now how mike did his routing and stuff i dont remember. but remember that he did that.

So what happens instead of running that tube from the VC to the intake track you just vent it straight to the atmosphere using a baby K&N type filter (and plug the entrance to the intake track)? The plus is that you're keeping your intake fairly clean, but is there a reason why I shouldn't be doing this?

it causes a pressure differential if i remember correctly. the crankcase wont keep proper pressure to keep things flowing in the right directions. if i remember right ***

Thanks for the info!
So with it hooked up correctly from the VC to the intake there is a greater pressure differential between the VC and the intake than between the VC and the atmosphere.... Bernoulli's law.
