I think the problem is your IAC valve under the throttle plate. What happen is the water passages gets blocked and does heat up the idle air pass through. This procedure is part of regular tune-up according to service manual.

I have a 1987 toyota pickup 22r carburetor i replaced the head gasket 2000 miles ago and now it blew again i had the head milled and new head bolts and i used a felpro head gasket what do i do now?


The 22R engine is one of the best engines Toyota built.

With the head off, you should have had the head gasket surface machined and the head checked pressure checked for cracks. It seems you did so.

I can only assume, you MAY have put the bolts back in without bowing out the cylinder block bolt holes before installing the bolts. These bolt holes fill with oil and antifreeze when you remove the head.

Doesn't matter how careful you are, the bolt holes always fill with fluid.

If so, the bolt torque would be reached before full clamping of the cylinder head. Worst of all, the block could have been cracked by the hydraulic pressure in the bolt hole as you tightened the bolt.

Is the v6 toyota engine bad in 94 pickups?


People prefer the 22r but the 3.0 is an o.k. engine, it just doesn't have the great reputation that the 22r has. If it is low miles then it will be fine, the one I had only lasted a month, but without knowing prior treatment, that really doesn't say that it was due to a bad designed engine. I say if the truck is in good shape then it will be a great truck.
