This is a repost of one I made in on the Chump Car Foum, as I am building a 1989 Supra (7M-GE) as a Chump Car endurance racer. I could use some help from you experienced Toyota guys.
I have been spending all of my time on the body, chassis, suspension and brakes, as the engine seemed fine. According to the previous owner, engine and head were rebuilt 10,000 miles ago and a new head gasket installed. But the spark plugs were shot and the so-called new exhaust was rusty as hell, so maybe he was lying about the engine, too.
Anyway, once I changed the plugs and oil, (and installed an accusump and oil cooler), the engine ran great, so I went on to other things. Yesterday, when I did a routine crank up (car is on jackstands) it was hard to get to idle until it warmed up and it was putting out intermittent smoke that was faintly blueish and smelled of oil.
So I let it run until it got to operating temp and played with the throttle a bit. It never overheated, and didn't smoke at idle, but if I got the rpms up a bit (3000) and let up on the throttle, then it would put out a cloud of blueish smoke.
I ain't no engine guru, so I need some help diagnosing the problem.
Do I need to pull just the head and have it professionally looked at? Or does it sound like something in the block?
Help?
