rattling sound coming from front of 2.5L
 

Hey guys and gals, I've got a 92 Wrangler with the 2.5 four banger and
it has an annoying rattle coming from the front of the block area. It
has 132,000 on the motor and the previous owner was mechanically
challenged.

I've changed out the rod bearings and oil pump to be safe (the rod
bearings didn't show much wear so I just plasti-gaged the mains and
they were within specs. Found out there was nothing to adjust on the
lifters so now I'm suspecting that there is some slop in the timing
chain and or tensioner.

Anybody familiar with the replacement of the wearables on the valve
timing on these engines? Best place to get replacement parts? Is the
tensioner spring over hydraulic or just spring?

Thanks for any help.

Tom

My first guess is the timing chain and chain tensioner are worn.

Does it quiet down with increased revs? If so this is classic symptom of
loose timing chain.

Re: rattling sound coming from front of 2.5L
 

If it's like mine, when I give it gas, no sound. When I'm coasting no
sound. But give it just barely a spot of gas and it rattles like crazy.
Kinda like just enough gas to match the rotation of something.... Mines
only in speeds above 45 or so. Been doing it for 3 years now...
