I have a 97 vitara (sidekick) no emmisions model 1.6 automatic
I keep gettting oil in my airintake tube it leaks all the way down to the filter i keep having to add oil anyone have any ideas as to what may be causing this? thanks

Im not sure what you mean my "no emissions" but it sounds like you might have excessive crankcase pressure and it's blowing oil through the crankcase breather on the valve cover.

you got a pcv valve still hooked up?

I just changed the pcv valve and the IAC valve. What do you think might be causing the excessive crankcase pressure?

Bad piston rings.

do you think its still the piston rings if i am not burning oil? there is no smoke out of the exhaust.

A compression test will give you a pretty good idea how wel the rings are sealing. It is possiable that the rings are leaking just enough to pressure up the crankcase but not enoguh to smoke.

yes there is a slight tapping

i had a 93 pathfinder that had the rings all broken thus the tapping, you may need to check ther compressin and then replace the rings.
