[masterjonny]

so i have the 420a motor ........the problem is I was driven last night and my friend was behind me and he told me he can smell oil and well i got on the gas it will blow out white smoke but when im parked at idle its not blowing out white smoke. When i start the car on a cold start my oil psi gauge shows around 55-60 psi but when i start driving and its warms up it drops to about 35-45 and at idle warm its about 15-20. it never done this before and i dont know what is wrong! Can someone help me out? thanks

Compression check time

How many miles are on it?

I agree with Bagged420a, do a compression test and possibly a leak-down test. As for your oil pressure, did you check your oil level?? My car at start up would be a little above 50 psi, and 25 psi at operating temp while idling. So I would check your oil level, but as to the white smoke, when's the last time you did a tune up?
