Has anyone on here replaced their own timing chains and tensioner? Or can you adjust the tensioner? I was thinking it was a "NON" adjustable part but was curious.
The easy part is the changing of the chain,,, hard part is to get to it.
As Tom said, it is a fairly major job.
If you are going to do it, do it right. Buy all the stuff for a tune up, change out the T-Stat, ANY gasket that is not easy to get to once it is installed again,,, ect ect ect...
If you do pull it, make sure the torq converter stays seated so that you don't have a need to replace the front pump seal.
Believe it or not I currently have a customer that has an Explorer that has about 115,000 that has been running with broken guides for over a year now, I don't know how long they were broken before he started regularily coming to my shop. Personally I have never seen one let loose based solely on broken timing chain guides but I am sure it has happened
This is a very old thread. But its something I'm considering doing on my '04 as preventative maintenance. My truck currently sits around 250k miles. I've no issues or symptoms which would indicate a timing chain issue. But I've never serviced it. The chain, guides, and tensioners are all original.
My truck has seen mostly interstate and highway miles, it resided all of its life in a rural area where a long drive to anywhere is normal. So not a lot of "city driving". that might be why it's done so well.
As it stands now, the engine is smooth with no issues. ....but the odometer reading is high.
