burning oil

[bluelx347]

I recently took my 91 mustang to get dyno tuned. The bearings, head gaskets and piston rings have about 350 miles on them and the heads have about 10000 miles. The tuners had to stop due to excessive oil burning. When i open up the butterfly on the throttle body, there is smoke coming up through the intake. How do i tell if it is coming from the oil rings, valves or guide plates. Thank You.

What intake are you running? What type of crankcase ventilation are you running?

I agree. Sounds more like a crankcase ventilation problem.

I am running a super victor 8.2 single plain intake with a spyder elbow. The crankcase is just ventilated to the atmosphere. I am not running a pcv valve. Should I?

Some people have problems with oil being pulled through the pcv system, but since you're not running that it could be something else. Does the car smoke constantly (rings)? Under load? After the car has ran/ sits for a few minutes off and is turned back on (valve seals)?
