1994 22RE Had Top End Rebuilt - Now Runs Rough And Burns a Lot of Gas.
Greetings, I am new to this forum, thus this is my first post (and boy is a big one). Maybe some of you out there can give me some insight into this issue I now have with a 1994 22RE.
The head gasket and timing chain guide (and was eaten by the engine - Thank God they are plastic) went at 197,000 miles. I had the top end done, and it ran great for about 1,500 miles. I am the original owner, thus I know every little sound this truck makes and every little vibration that it should not have. Well, one day it began to run rough like it lost a cylinder and began to burn a lot of gas. I took it back to the shop that did the engine work, and their best guess was a bad fuel injector. I also checked around with other shops as to what it might be and the almost universal answer was that the valves need to be checked/adjusted at 3,000 miles after the overhaul. My shop did the check at 1,000 miles and declared it OK. Thus, here is my big question:
Are the folks that say it is the valves be correct?
I talked with one shop that said the head may have been incorrectly machined, thus the valves are seating too far into the head. Can this happen?
And finally, what are the best spark plugs for this engine?
Confused in Los Angeles.
