I have a 1991 toyota pickup with the 3vz-e v6 engine option, and the head gasket blewThe gaskets are faulty because there was a factory recall on them and its very apparent why they leakedThe engine didnt overheat but they are aluminum headsi got them roughly checked and they seemed to be in toleranceive heard from many sources that you should get the heads resurfaced and change the head bolts as precaution but we want to avoid these things(the bolts because it would require removal of cams and they are torqued very tight and i already have the heads off so id have to put them back on the engine to get the cams out) so does anybody know if itd be a a risk worth taking just putting on replacement gaskets and reusing the bolts? i am aware that its a possible risk doing so but im trying to weigh my options.
Generally, the heads should be resurfaced, especially if the engine overheated and even more especially if the heads are aluminumReplacing the head bolts is purely a question of engine designSome engines spec the bolts to be torqued into the plastic zoneReusing such bolts is a really bad idea as you are likely to break one, or fail to develop enough clamping force and have another blown gasket shortlyOther head designs leave the bolts in the elastic zone and reuse is OKOnly a service manual can tell you what to doAstrobuf
nope, but if you jump into it too soon, you could get alot of gas, and even constipation from too much fibergood luck!
