Hello,
I have been lurking around the forum over the years, but never really had anything wrong with any of my older toy's (1985 22RE Pickup 4x4, 1988 22RE Pickup 4x4 and 1992 Toyota Celica GT-S)

Well, those are all gone now, and I have a 1990 22RE Pickup 4x4, that I bought last fall. I knew that it had a problem, but I bought it cheap enough that I could do some work on it.

It made/makes a bad knocking/tapping sound from the engine. I adjusted the valves and it is better but still there. The engine has 274000 miles on it, and as far as I know it has never been rebuilt.

Also, the bigger problem is it overheats. I am getting exhaust into my water jacket somewhere. It super heats my coolant and evaporates it and causes the engine to overheat. I don't know if it is my head gasket, head or block that is the problem. I assume that it is a head and head gasket. I only live about 7 blocks from work (small town) and was waiting till I could ride my motorcycle to work and around before I tore into it. Now that time has arrived.

So, now I need to know if I should just get a new complete head (with or with out a RV Cam, not sure which one to get or what difference it would make.) Get a normal rebuilt head with a stock Cam or ??? I have rebuilt engines before, so I am not scared to get dirty or have to mic stuff to check for bearing size.

I expect to buy a complete rebuild kit after I get it torn down and see what size I need for things.

What should I do about the head? and noise from the valves/cam? how do I know when they are too warn to use again?

Should I be scared that my block is cracked? Is that common on 22REs?

What are your thought on a RV Cam vs a Stock Cam and what duration of lift would be better for a RV Cam???

Is enginebldr the best place to buy my stuff from ???

Thanks for all your help!!!!!

You could do a compression test on the engine, and a leak test on the cooling system to help locate the problem. More likely the HG or head, rather than the block, blown HGs and cracked heads is fairly common on the 22R (but not nearly as bad as the 3.0's HG problem).

You can't go wrong with parts from EB, stock or RV cam is up to you. Check his site for cam and head details.

Thank you for your reply. I did do a compressions test, if I remember right one was 170 and the rest were 140. I haven't done a leak test yet.
