Okay guys when i replaced my t.c. the last time i noticed that there was alot more slack in the chain than there was with other 22re's that ive replaced the chains on. Also my engine seems to be a little more noisy. The noise sounds like its coming from the front of the head and im thinking that it could be because the camshaft journals are worn bad enough to let the cam gear to ride differently on the distributor gear. Is this even possible? Would this also cause the excess slack in the t.c. that i noticed? Thanks in advance for the help guys!!

No ideas?

Do you know if the head or block has been decked?
May have been done if either was slightly warped before.
Just a thought, but that could account for the slackness in the chain.

yes , as above .. you might need the spacer

>>>*Morning. Sorry for neglecting you guys lately, I have been out chasing Cows, we have a new Bull that for some reason doesn't like virgins and is more interested in our neighbor's old stuff...*LOL**..

*Anyway. If you had that much wear in the cam journals, enough to seriously effect the geometry between the crankpin centerline and the cam centerline, trust me when I say you would know.

I have seen some pretty noisy cam drive gears though, usually from wear.

A typical resurface on the head/block does shorten the centerline distance, but the tensioner can easily compensate. We consider .020" total to be no real concern, although of course that also retards the valve timing. The effect is a slight power increase at a slightly higher RPM.

Slack is usually a result of excess material removed, in which case the use of a thicker head gasket (.020" thicker is readily available) or the less desireable block saver shim can be installed.

One quick check is to see how far the tensioner arm extends to take up the slack. Excessive is when the travel is about halfway or more. I remember way back installing the first few sets and thinking they were going to rattle, but the tensioner (basically just a hydraulic shock absorber) does it's job and they didn't.

Also check that common problem of the top oil pump holdown bolt, the one that goes where the timing cover is drilled all the way through? If that bolt is too long and even touches the tensioner pad, that will cause noise by stopping the arm.

The other common concern is dirt or debris, any that gets past the filter ends up in the tensioner. Over tightening the tensioner bolts is the other sometimes problem, it doesn't take much to distort the tiny thing. We use 12 lbs ft there, all it has to do is stay in place.

Hope this helps.....*EB

the engine was rebuilt probably 10,000 miles ago and they said they shaved the head and worked on the block. They did a crappy job with everything though. Didnt replace many parts that they said they did. They even put the old tc and tensioner back on the new engine. Still pisses me off thinking about it. Now that ive been into this engine so much fixing their problems, i believe I couldve done a better job on such a simple engine. But i dont know if they put a spacer or anything in there. When i put the new chain kit on, the tensioner was extended at least halfway if not more. Thanks guys!!!!!!
