Thread: Cylinder head buggered???

I'll keep them in mind. I cranked it up to 3K rpm on the hand throttle with the cap off the radiator. It bubbled at low revs but I think that was more to do with the vibration of the motor. At high revs it did nothing just sat there. It's a 3L, not a surf. Meant to be relatively bullet proof. Hopefully it's nothing major. Toyota does have some what of a reputation of bullshitting.
