93 22RE loud valve noise
Just drivin home from work today at about 35mph and what I assume is a vavle started making lots of noise....... was OK under 15mph so limped home. 140,000 miles on 2wd 22RE pickup???? Any thoughts would be greatly appreciated, thanks for your time,,,, TIM

Since no one else wants to respond, I'll give it a shot.
Take your rocker cover off and inspect your timing chain to see if either one or both of the timing chain guides (manual calls them dampers) broke and for excess slack in the timing chain. Also look at the two guide bolts on the drivers side to see if you can see shiny marks where the chain has contacted them. The chain contacting the cover or those bolts can sound very much like valve noise.
Excess slack with good guides may mean a bad or clogged chain tensioner. I just went through it. Bad guides means that the chain is hitting the side of the timing cover.
There is only one way to fix it if that's what it is and with 140K on it you may as well replace the whole timing set. That seems to be right around where the timing chains fail on these things. You want to replace it before it actually breaks or jumps teeth since it can do valve and piston damage when it goes completely.
Wish my advice could be more pleasing to hear.
Good luck.

Thanks for the input........ It ended up being a blown headgasket between 3 and 4......... water doesn't compress to well. Anyway... I'm gonna do the timing chain while it's all off, thanks againj....TIM

Do yourself a favor while it's apart. Behind the tensioner is an oil port that supplies the tensioner. A little below it and to the left is another one that is a little bigger. Get hold of a blower for your compressor, assuming you have one, and blow air through the lower one. It will blow out the tensioner one. I had an issue with mine and had to take it apart. A whole lot of crap came out of it.

Clogged timing chain tensioner hole...
Is this fairly common on the 22R/RE ?
It sounds like an awfully good reason for staying with oil change intervals of under 4,000.
