hmmmm good post, my 92 22re
has 186k on it
got me thinking???

 

Why not just spend the 140 bucks, get the metal timing chain guide kit, replace it all, and never worry about it again?

 

The point of preventive maintenance is to replace things that might break before they do. If some only last to 90,000 and others last to 200,000, it's prudent to replace it somewhere around 90,000.

Otherwise, remember that some 22r/re's last more than 1,000,000 miles. So why not wait until then to fix it?

 

I know you guys are right, I just rolled over 100K miles and I plan on doing it soon. It is running really well right now so I think if I wait a few months it will be fine.

 

use good thick oil in those engines and nvr let the oil ight come on and that chain should go 200,000 plus another key issue is dnt put your vehicle in first gear and let it roll backwards as the timing chain is suppost to roll in 1 direction and turning it the opposite way can cause alot of bad torque in the wrong direction either breaking or def shortning its life. (ive had it done to me. it rolled backwards in first gear and i literally heard it snap and drop. thought to myself that sounded odd went to go start it up and sure enough it wouldnt.) ive currently been running my 22re on a broken guide and its goinng on 100,000 like that. 400,000 on the whole engine. depends how it breaks mine broke itsself off the bolt and not site against the timing cover but tansioner takes up the slack after running afew seconds.

 

Just an update on this thread, I am at 137K miles and no signs on wear on any of the timing components yet. Not bad as I have put 40K miles on this truck since I bought it in August of 2009.

 

Just changed the timing chain on my 22RE at 135K miles. Engine is well maintained and I don't drive like a maniac, but the plastic guide on the driver's side was broken at the upper bolt hole and needed to be replaced, which I did, with a metal backed guide.
I damaged the head gasket putting the timing cover back on the engine, now I'm replacing that. Pretty tough to wedge the cover back in without removing the head and/or oil pan.

 

mine broke at ~150k, and i replaced it at 175k. there were grooves worn into the cover, but not all the way through.

if i had to do the repair again, i would invest in an engine hoist and pull the engine out. that way, you can easily get to everything and have lots of room to fix stuff

edit: i rebuilt my engine as a n00b... i did have some wrenching experience, but a lot of help came from everyone here on the forum. definitely a good project

(rebuild link in my sig- the orange one)

 

I have 283k on my 22RE. oil changed religiously every 3k since new with 10/30. timing chain is original and i hear no noise.
I plan on changing it soon as I want to challenge how long this Orig engine will last.
