timing chain guide info on 4.0 sohc

[suzukikid68]

ok am new to this sight so any help is appreciated. Had rear timing chain noise, had new ones put in. Drove it for about 5 miles, ran good no noise. Go start it up couple hours later back it up, was fine. Put it in drive to put in garage and the timing chain noise is back. What could cause the guides to break so fast? I cant believe all the time and work to do this and cant even last past 5 miles. Anybody have any ideas what would have caused this? I dont know if they were bad parts or something else. please help

rear cassette replaced?

Replacing the rear timing chain and guide requires removing the engine or removing the transmission. If neither was done then the cassette (chain, guide & sprockets) were not replaced. Maybe just the tensioner was replaced which often does not eliminate the timing chain rattle. If the cassette was replaced it may have been with some of the inferior parts available on the internet. See my helpful threads to learn more about the SOHC V6 timing configuration.

yea everything was changed. I got the parts from a garage, which I thought would be better than part store. I wont know what happened till I tear it back out and see. thanks. Now if it is a faulty part, shouldnt they replace it for free? they never said anything about a warrenty when I bought

warranty?

A warranty usually only covers replacement of a defective part. If the work was not performed by a certified mechanic using the proper tools and following specified procedures then the supplier may argue that the part failed because of improper installation. At least one forum member had the rear hydraulic tensioner seize upon the first engine start after installing it. The seized tensioner caused the guide assembly to break. It is probably a good idea to oil the tensioners and check them for free movement before installation. The OTC 6488 timing tool kit simplifies installation of the cassettes and reduces the risk of timing the camshafts incorrectly.

You can take your valve covers off and see if it jumped time. I had it happen to me on 1 of my 4 attempts at timing my 2004. Like they said above , you need the timing tool and be sure that all the bolts are torqued perfectly and you don’t miss a step ! Keep it at TDS always through the entire process. If anyone needs any info , don’t hesitate to ask. I will pay it forward with no problems. This is an old post, but maybe someone will see this and need some advice. Take care
