Burning Oil

[MrTristoe]

My car burns quite abit of oil in between oil changes, and im getting too much pressure somewhere which is causing my dipstick to get pushed out frequently. some one told me it could be the pcv valve. how could i test that and what else could cause a problem like that.

Don't really have a valve, check inside the throttle body for oil. You have to pull the valve covers and clean the pvc outlets.

Smoke coming out the tailpipe? If it's pushing out the dipstick you probably have too much blowby.

Also check to see if when the car is at idle open the oil cap if a lot of smoke comes out and smells like oil & gas i wouldn't drive or run it any anymore man its blown rings.

i havn't seen any smoke at all. ill check in the morning if theres any smoke by the oil cap.

Check to make sure that the port on the throttle body that goes to the valve covers is clear by spraying some brake cleaner through it.

There was a VERY similar thread like this... Be back in 5.

Edit: Couldn't find, but do you have any engine shots? (pics)

i know im late on replying but ive done a compression test on the car and compression is good. it was all within 10 psi of each cylinder, alsoive checked the pcv valve and replaced valve cover gaskets, went with a heavier weight oil, and im still having the problem. no smoke from the oil cap. im starting to run out of ideas of what it could be...

Aw shid i just read about the dipstick. Do you have the PCV on the valve covers routed to the intake?

^ not sure if my terms are correct

A heavy oil in a 7M will just float the rings and burn more oil. Stick with 5w30.
