Broken t-belt w/ pics

[jott5555]

Been a while since ive posted in here so here we go

the gf is driving my tsi, w/ a freshly built 6bolt. first 500 miles @ 10psi last 200 @ 16psi. so she rolling along and it dies in the intersection

upon inspection i see a blown off mani to bov line reconnect it and went to start it and heres where it gets weird

the starter sounds like it is spinning but the engine dosent turn over. so i replaced the starter with a known good one. the fly wheel and the gear ring around it felt perfect as far as i could feel though the starter hole. but with both starters all i hear is the starter spinning..

so my thoughs are.. flywheel either came off the crank, the small black wire that enguages the plunger part of the starter silinoid is shorting out and causeing it not to advance forward or something else cuz im freakin stumped..

Any imput is appriciated

thanks guys

i went out and turned over the cams and i could feel the belt slipping on the crank sproket so looks like a new timeing belt for me..

Ouch...sounds like a tensioner let go. Do you know if it bent any valves yet?

 

[jott5555]

i dont know yet.. the thing is the tension along wiht everything else is brand new oem..

argggg

well. pulled the tbelt cover to find this.. any ideas what started it?? also on the tbelt cover there are 3 or 4 gashes form the crank pully..

My condolances...

Well it looks like im not the onlty one who had t-belt problems...Same exact thing happend to me at a lite..Ive got to check for bent valves

you (and several others) are the reason i am changing my crank pully on this project i am working on. i have read that the crank pully should be replaced about every 75k so it does not start coming apart.

sorry for your loss,

the thing is mine still looks perfect. no cracks in the rubber or anything.

as dsmers we need to get together and fix this decease that plague's the 4g63

? The crank pulley wouldn't have anything to do with this, it just runs the accessory belts. Whenever it seperates the inner part that's connected to the crank continues to spin normally.

Unfortunately, you can't "fix" this - because of the interference design of the engine, if a timing belt breaks, valves are gonna get smacked (they occupy the same combustion chamber space as the pistons at different points in the stroke). The only way to prevent it is to stay on top of maintenence and change your belts, tensioners, pulleys, et al religiously.

maybe it is the cursed gf/wife thing...it seems that half the time my wife has driven my gs-t something goes wrong (fuel pump, blown speakers, a handful of other minor things). she is no longer allowed in the drivers seat of my car. of course my wife is 5 years older than me, and all i hear is..."i have been doing this longer than you..." and then something goes to sh**. buy a beater and if she needs to borrow/use one of your cars...give her the one you do not care if she breaks.

Looks like the tensioner pully didn't do it's job. I tried intalling mine according to specs and it was a little loose after the procedure. I re-installed it the way that it made sense to me and so far have 3000 miles with no problems.

but what happens with the outer part? or belts when thing start letting go? what if it happens to 'slide/spin' back into the t-belt? however, i do agree that staying on top of maintenence is the proper way. during my little project (car w/95k miles) i will replace it even though it still looks good because i have read that this can happen and take out a t-belt. weither (sp) it is true or not...i am replacing mine.

It can't slide/spin back into the timing belt - the timing cover is in the way.

not to be a pest...but the timing cover is a plastic pos. i am sure most of us have had things come apart before, and in a really destructive way...but will that cover really stop spinning/flying debris from entering the t-belt area (not that this is what happened here)? anyway, no matter, mine is going to be new for this project even if the reason is not correct. as you stated...it is a maintenence thing.

do not re use that t-belt. god forbid you cant see something wrong with it you'll be redoing the same job. and you'll bend another set of valves. its not worth saving 50$-75$. just get a new belt for peace of mind

as i stated in the post this was all new hardware, new tensioner, new belt new pullies. and after inspection i beleive what happened is the upper alt arm was loose caused the alt and crank to vibrate, now there are several gouge marks on my tbelt cover from the harmonic balancer which i beleive pushed the gasket for the tbelt cover into the tbelt and caused me all this damage.

that is what i think happened ####ing 80 bucks for a tbelt.


anyone wanna buy a 1g jk
