you are burning oil.

carbon-vtec · 06-05-2003, 10:03 AM

i checked my oil and apparebtly i have none

carbon-vtec · 06-05-2003, 10:04 AM

do i buy any kind of oil and fill it up or something?

If your burning oil you should consider going with a heavier wieght, or you could use a 2 cycle oil like for lawnmowers. Major horsepower gains from that stuff....

Jk man Mobil 1 is what I use. but don't mix synthetic oil with regualr oil

this could , could be the onset of a bigger problem, ever thought about that, maybe you finally messed up a piston ring or something like that. just a thought, theres a handful of reasons wny one would be burning it.

There has to be oil in it, if there wasn't the light would be on and by him saying there is none he probably means that there isn't any on the dipstick which means he is at least a quart and a half down. He is prolly burning through the vavle train or the rings is what concLude is saying.

bsi · 06-05-2003, 05:21 PM

know the light does not always come on when your low on oil thats how my last engine went the way of the 5th gen ss tranny!

carbon-vtec · 06-05-2003, 08:59 PM

actually some of my wiring is screwed up so none of my dash lights work now

bullseye.......i think to test the rings you could alwayes run a compression test on it.

I just registered on this site after reading the comments here. I have over 40 years experience in the field of automotive machining and have inspected and assembled untold numbers of engines of every type. Including racing engines. In my estimation, and unless there has been a serious broach in the air filtration, the oil consumption problem stated here is from worn valve guides, or valve stem seals which over time have become hardened and now fail to perform their purpose. Very rarely does an overhead engine develop piston ring problems.

Iknewit, any quick test for that? same problem here!

I wish there were an easy way to check this problem, but I'm afraid the only way is to replace the valve stem seals. If the head is removed it is much easier to check the guides because an 'on the car' seal replacement requires that the valves be held against the valve seat with 90 psi of air pressure. I'd almost bet that if your seeing oil smoke, it is coming through the stem seals. Good luck and I hope I've answered your question.
