No compression on one side.

[joey_hv]

I have a '98 that just lost compression on cylinders #1,2, & 3 on the passenger's side of the engine. I have been informed by the dealer that it is prolly a "jumped time" incident and I have to "adjust" the timing chains.

1. why would jumped time only screw up one side of the engine?
2. what timing chains run that side of the engine?
3. does this have anything to do with the main front chain?
4. how dificult is this to repair?

any info would be great.

ps: I am actually changing out the engine for another one but I want to repair the engine I pull out if possible. so any work I do to it will be while it is on an engine stand.

let me guess.... you have a sohc. you lost the cam drive on that side.... lots of posts on sohc timing issues.

yes it is a SOHC, and I did a search but could not find a thread that discussed re-setting the timing. the biggest thread I found just talked about changing out the plastic chain guides in the front of the engine due to annoying rattle.

basically i need to know how to get my engine back in proper timing and repair the reason why it "jumped" out of time. :roll:

It is unlikely that your timing "just" needs to be reset. You have more than just that problem. Once you take of the cover (not sure which front our back), it will become obvious.
