Hey guys, Putting my LA 360 back together and im reusing my old timing set. Its a Cloyes true street roller, and even when it was brand new the chain felt kinda sloppy...I re installed it the other day and im not sure im too happy with how it feels and was thinking of using a tensioner on the chain to take up the slack. My worry is the reliability of these pieces (All I know of is the MP one...are there other brands?). I have read of some using them with great success and others saying that they get eaten up. My car sees upward of 3000 miles on the street every year, and lots of very hard driving on and off the track. Rpms will be under 7k. Not sure if any of this has a bearing on whether the tensioner will work ok in my application. Is there any special install guidelines that anyone recommends when using them? special lube? effects on cam degreeing (already degreed the cam but can be done again if I should). Just looking for some opinions on whether these are a good piece or if I should stay away from them and any tricks or things to watch out for when running them Thanks Matthew

I managed to get one when we were doing these all the time in the dealership. Seems like a good idea---but I can tell what happened to mine. I was mocking up my 360 and put the chain on by itself. Motor turned over effortlessly (just crank, cam, and chain). I then put the tensioner on and the struggled to turn the enging over with a 3/8 ratchet. I pulled it right off in the trash it went. I just couldn't see putting the added drag---a significant amount--- on the engine. Not worth it in my opinion at all just for that reason alone, let alone any wear issues tha my occur on the wear pads.
As long as you buy a good double roller, thats about the best your going to do short of going to the Milidon gear drive. Which I eventully did and had rock steady timing.

I asked Ryan this when I was ordering parts for my new bullet. He said to run one, so I am. We'll see how it holds up to all the street driving and passes I put on in a year.

When you see how much the nylon wears in such a short time, and it's all in the oil/oil pan you'll never run one again!! Gimmick if you ask me. Buy a good timing set and be done.

I would never run one, just buy a good QUALITY chain and gear set. It may be a bit pricey, but a lot of times you really do get what you pay for and being cheap is not the way to go in the long run! I have never been dissapointed buying quality parts over buying cheap parts...

I agree,,,,never liked them, never will...dont think you need one. No way of telling from a computer screen what your dealing with as far as "loose", but it could be the align hone if there was one, a cheaper timing set with a chain that stretched easily, sprockets wearing faster than they should, or lack of oil supply to the timing set.

I just pulled my motor apart due to a wiped cam after a few thousand miles. When I built it, I installed a Cloyes tensioner.
There is visible wear on the pads. Wish I had pictures handy, but the chain “bars” have worn grooves in the pad. Looks like it wore in until the rollers started hitting the pad, and then stopped. With the effective bearing surface increased, the wear will probably stop.
Before I re-assemble though, I’d like to hear some other tensioner wear stories.

Thats the normal wear pattern... as soon as it gets more surface area it slows right down on wear

I agree here, but its a total crap shoot, and personal preferance. Will one make or break an engine, doubt it, will I run one, NO, do I care if someone else runs one, NO. All part of the Hot rod game. Some people LOVE header wrap, some HATE it, same thing here. Kasey
