which timing belt?

[Larry L]

I'm having my timing belt done this week and i wanted to know if i must use the Mitsubishi belt or can i use an after market one? So what timing belt are you using?

 

[GSXanimal]

I have always used oem, a friend of mine used a goodyear but after 5000 miles it has cracks between the teeth, maybe just a defect but I would stick with the factory belt.

I m going with the kevlar belt that Mach V has for sale. Seeing how the TB is the most important part of our engines, i htink it s well worth the extra dough.

The Kevlar belt is nice. It can be reused something like five times but you still need to replace the auto-tensioner and the pulleys as often as before. The Kevlar belt doesn't save you from doing timing belt jobs. The Kevlar belt will pay for itself if you reuse it more than once. Otherwise, just stick with the OEM belt.

i dont see a need for the kevlar. Yes its nice and lasts forever, but is your car going to last 200,000 miles? its a dsm so the answer is probably not. Shit, i dont think i'll drive my current project dsm 60k in 5 years, so the extra money doesn't seem worth it to me

I wouldn't use anything but OEM.

The two main things that have really got me sold are this:

A: No stretching of the belt, and thats a very good thing, as timing wont be changed over time as it would when a normal belt starts to get weak.

B: I used an OEM belt on my car, something got into, or got loose inside of my front cover, and has chewed my "great" oem timing belt up to the point that it makes me nervouse to drive it. Thats why I m going with the kevlar. The timing belt is the heart of our engines, what is an extra hundred bucks insurance compared to the cost of an almost new engine?

Chew on that for a minute.

 

[kpt4321]

Don't use a "better" belt as an excuse to let shit get inside the cover and screw up your motor. Stuff shouldn't be in there, don't plan for it to happen.

 

[2FastTSiAWD]

I m not using a "better belt excuse" The simple fact is that I was not planning for anything to get in my engine, but thats the thing, nobody plans for these things to happen. It s called preventive measures. And if you dont believe in those, then pull your knock sensor off your engine, cause yep, you guessed it, it s a preventive device that protects your engine in the event that something "were to happen" Would you take that chance? No, then why take the chance with a much more important peice of your engine?

 

[kpt4321]

Hahaha. The knock sensor has an entierly different prupose than the timing belt, but good try. I'm not even going to argue about this.

 

[splattj]

The problem is that a rock or nut that gets in your timing belt assembly and "eats" a belt is going to eat Kevlar almost as quickly. The only real benefit is the non-streching thing and thereby the ability to reuse the belt a few times.

Buschur is now using the kevlar belt also. My next mod will be a kevlar timing belt. Rev to the moon and never worry about it again.

Mine is at 190,000 miles does that count? Still runing good too. Just that whole pesky blown 14b problem.

Well I purchased the OEM belt, and my wife took it to a shop to have it done as a gift to me..All good exept there is a hummm and vibration at around 5K rpm... Took it back and they tried to say it was my exaust... But my whole dash vibrates from it and it cannot be heard in the exaust tone The idle is also crappy.
Need some opinions please.

List of things changed:

Water pump
OEM Timing Belt
Balance shaft Belt
Front crank seal

 

[kpt4321]

I wonder if they didn't set the balance shaft(s) up right, so one or both of them is out of phase.

It could also be that one of the cams is off a tooth.

I would take it to a real DSM shop, they will fix it.

 

[Larry L]

If it is the balancing shafts that are not up right could this put me into crankwalk?

The cams gears are off a tooth. whn they changed it for u they must have been in a hurry or something, so unprofeessional.

And that would vibrate so bad? It feels like a weed eater when its out of cutting wire.
