Big bummer.

I finally got around to cleaning the head block that I took off not too long on my 83 toyota truck, and I found that coolant holes at the front and rear of the block had eroded edges - probably the source of my headgasket problems. I guess this is called cavitation? What causes this? This was suppose to be new a head installed by a shop in January 05. Can this be repaired or is the head basically toast? Where I can buy a good one if needed?

I am so bummed.:sosad:

You can have it resurfaced, but be sure it's done by a surfacing machine that has carbide inserts, not the stones that are ok only for iron heads. Makes it all shiny too.

actually its called ..........electrolysyss........ usually caused by the coolant turing acidic . I doubt the head is "new" ..... maybe a new/used one . Antifreeze should be changed every 3-4 years , depending on miles you put on it . system should be completly flushed , and NEW antifreeze installed .

head can be repaired , depending on the damage ... we use to have it welded , then machined back in the old days , but now the heads are cheep and plentifull .... I would look for a good used one , in your area , ... I infact have one in my shop .

thanks guys. i'll check out the auto machine shops in my area...hopefully it wont be too expensive and sources for used heads...and weigh my options.....can a headgasket blowing cause the cavitation? thats what some guy said at work.

NO .


NO question .... it is the antifreeze .


I have seen one so bad , that it had eaten away the impeller on the watter pump .
