[Shotimes] Failing Cam Timing chain tensioner sound?

[Ron Porter]

Then why worry about it? Drive it until you swap motors. With as bad as my
rod bearings were, I put another 600+ miles getting the car home before I
changed them, and they may very well have been toast during he whole Summit
Point and Mason-Dixon abuse.

See that's what I thought, but I changed the bearings out when I thought I
might have had a spun one, and this isn't a knocking like I had when I found
the spun one. I could prolly drop the pan and check it out, but with the 15F
temp outside right now, I really don't want to deal with it. I put my broom
handle on the oilpan just to check and didn't hear anything, which made me
fee at least a little better. Then again with my luck it could end up being
something like a pin on the piston or something like that. The Opal's 3.0
only needs to last another 2 weeks, then the green winter beater will be on
the road, and I'll be sure that it is not in need of anything else.

Well, noises in the 3K range are generally bad rod bearings, from what I
have experienced.

Can anyone describe the sound a failing tensioner would make? I have this
wierd rattling sound that is only present from 3000rpm and up, but it only
happens some times. I've verified that it's not the TOB as it doen't go away
when the clutch is pushed in. I seem to really hear it coming thru where my
pillar pod is mounted, as the spots where the clips used to be affixed are
open, and I think they carry sound from the engine bay up into the car. I
put a piece of a broom handle on the tensioner area of the front head, and
there is a slight noise there, but not like waht I'm hearing while driving.
The back head is silent as far as I can tell.
 
Is it possible that the front tensioner might be failing, and letting the
chain slap around, and if so is it something that can kinda happen one day
but be quiet the next? My Opal is up to 95k miles and is perhaps a week to a
week and a half from comming off the road for the winter. I have a 3.2 that
will be going in there over the winter, but I wanted to troubleshoot this
and see if it's gonna be ok to keep driving on it till I've made sure the
winter beater is up to snuff so to speak.
 
Is there any sure fire way to test out a tensioner and see if it is bad? I
know it's like a 25 min job to get the front valve cover off, 15 of that
being the intake. :-)
 
Thanks in advance
