So I'm interested in buying a Supra. The engine has been rebuild 15k ago. I'm happy with everything except the engine has a problem. This is a quoted description from the owner.
"Has a metal on metal piercing type squeal coming from "sounds like" along the fuel rail/intake manifold area,
intake manifold, injector o-rings/grommets/throttle body gasket/iscv gasket have been replaced. the squeal sadly remains.
reacts to how cold it is as well. sometimes it is barely audible and if it randomly gets louder my idle will immediately be affected and bog down and behave erraticly. "
I'm wondering if this is bad news, and what I could do to check out the potential damage of this issue. I was thinking of doing a vacuum test, compression test, and possibly a leak down test if necessary. I just want to make sure it's something fixable, and not a blown engine or head gasket. Thanks in advance for any input and guidance.
