That's not bad, I was expecting closer to $700.

So while on this topic, this may be ridiculous, but is there such thing as a performance timing belt? Like why not upgrade if it's getting swapped out already, right?

 

lol you were lucky cranswick. me.... not so much which is why i ended up just getting a new head from rrm

 

So what are the chances of damage to some other internal component, and how severe could said damage be?

 

Reason i ask is because i usually work on Evolution's at the shop but a friend brought in a Outlander with the 4G69 that also split the belt and nothing at all was damaged .

Ive seen Evo's destroy the head , and all the pistons just from this happening .

 

okay first of all, make sure that the timing belt is the source of the problem. then you can worry about damage.

IF it is the timing belt than you'll want to get your valves as well as your pistons checked for damages as the valves may be bent which would cause you to lose compression or the pistons will have dent marks in them, not sure if that is a problem or not

 

"The 4G69 incorporates Mitsubishi's MIVEC Variable Valve Timing technology. The 4G69 is an interference motor like the 4G63"

I know wikipedia is often full of shyt, but this is just a quick search i just did. I have read it elsewhere, and in my case i don't know if it was do to with the cam angle, or engine rpm at the time it stripped, or what but others on this board were not so fortunate. And if you check i think page 2 of my rebuild thread, the pistons clearly made contact with the valves.

 

The car in the video sounds just like my old 4G63 Talon did when the timing belt stripped its teeth. The starter is working fine, engaging and spinning the crank, but without the timing belt turning the camshaft, it won't start because the valves are not opening and closing as they should.

Pull off your timing cover and see if the cam moves when you turn the crank by hand. I wouldn't risk further damage by using the starter.

If this is the case with your RA, and there is no other damage, consider yourself EXTREMELY fortunate. The 4G69 is an interference engine, like the 4G63.

When the belt in my Talon failed (at idle), I bent all the valves in the head, broke the head off one of the exhaust valves in the #2 cylinder, which trashed the head and put a hole through the #2 piston. And made that same whiir whiir sound when I tried to start it.
