Ok i aint gonna read all the replies but if its only on start up it has to be your intake valve springs, hey r worn and not sealing the combustion chamber and letting in oil through the valve. I would take them out and check the valve spring free length and spring pressure, i am almost 100% sure thats it. Bucz once u heat up the spring and valve it expands and then seals properly.

no


valve seals, when the engine is off oil pools around the valve stem since the spring seat is a depression in the head. the pooled oil then seeps through onto the backs of the valves and stays there till the first startup. or it goes right into the combustion chamber, depends what position the valve is in.

I have no idea what u just tried to explain. u mean guides? seals r just at the top of the guides and even if the seals were bad the oil would have to pass the through the valve guide still. And if the seals were letting oil pass it would do more often then just start up.

sorry i got mixed up i thought he meant no compression as well. But i dont think its just the seals might be guides too.

no, seals. the guides are not a seal, the seal seals. the guide is more of a bearing that keeps the valve straight as it travels... its an umbrella type on these toyotas which hardens and does not seal well over time. the valve seal sets down by the spring seat, which is a lower area of the head, so oil pools there when the engine is off. the hot thin oil leaks past the valve seals, down the valve guides, and into the combustion area. if the valves are closed it pools ontop of the intake and exhaust valves, or if the valves are open, it leaks into the combustion chamber.


i dont know how to more clearly explain this, beyond with pictures.

ok i see what u r saying but if its the seals that r bad would it not be burning oil all the time?

wait.


Blue smoke. Wouldnt that be gas? burning oil is white smoke.

no, when the engine is running the oil doesnt collect because the valve train is splashing it all around. but yes, you do burn a little when running all the time, but its such a small amount its not seen in the exhaust color. because it trickles down and collects when the engine is off, thats why you see the puff.

Burning gas is greyish/black and like I said earlier sometimes in rare cases white, and burning oil is blueish smoke and green smoke is Nos yo....lol

lol this is weird i have the exact same car and year and my friend told me my car was puffing bluish white smoke today

then i saw this
