Question about 1991 Toyota Supra
I just purchased a 1991 toyota supra and i am wondering if its the turbo makeing this happen blue smoke only when i let of the gas idles perfect turbo works good just the cloud of smoke when you let of the gas
The intake valve guide seals are worn and are letting oil slip by under high engine vacuum--as when you let up on the gas. The only fix is to take the cylinder head off and replace the valve guide seals. This problem is pretty normal for an older car with high mileage. It will probably run just fine. Just keep checking the oil level and keep it topped up.
