Gates Kevlar belt ripped with less than 15k miles :(


Recommended Posts

As I was taking a turn the car just turned off. While I was coasting ( under 10 miles ) I tried to start it up again but to no avail. I'm in the middle of tuning so I presumed that the shut off was normal. When I try to start it, it seemed as if the starter wasn't even turning the motor over like something was jammed it. Took a look around, check level. All was good. Had a 10 mm with me ( good to have on hand) and thought to just take a look at the belt and low and behold I found this. It looks as if the belt is still Intacked And no teeth jumped but well see. I just hope this was the reason why it turned off and not another issue I just found.

 

So I'm sitting here waiting for a flatbed and decided to let you guys know

Sorry for your problem, at first thought, I'm thinking install error.

 

Also guessing the reason the starter stopped is because a valve is stuck in a piston.

Well I found the culprit. A bolt got jammed between the pass. intake cam and timing cover. It looks like a timing belt cover bolt, but not sure where from as I still had all the bolts on the cover. I also need to get a new cover, they all have cracks and openings.

 

Now I need to align pray that it didn't jump.

Those are ACVS gears Dan.

 

That does not look good. Pull the belt. Set the crank to TDC. Set the cams to TDC. Install the belt. Perform a compression check. Pray you dont have all zeros. We should all pray he does not have 4 cyl with zero.

Tried to align it while the belt was still on and marks were off on all four cams. Looked like it Jumped big time, so already expecting the worse. I got the belt off and all the plugs. Tomorrow I'll run a compression test. I also bought new plugs just in case. Also already purchased another Gates belt and starting to look into short blocks (suxs big time if I need one)

 

Found out the bolt came from the waterpump. Must of loosen itself out after 15,000 miles =/

 

Oh and, some damage on the pass. cam gears. Might need replacing ?

See now this scares me as this is the exact belt and water pump kit i have coming for mine next tues. I know you said you had a bolt come loose, but i'm doing the job myself as i can't afford to have someone else do it, aka shop. I have loctite, should i apply that to all my bolts just to be sure? Other than this, how did the gates belt perform?

plenty of people here have put a 100k on these kits. this was clearly an install error

Due to AVCS, the lines on the belt wont come back into alignment on the gears again. But, the alignment marks on the gears should come back to tdc.

 

I have seen worse. In LGT's. Even if there was interference, you might have been lucky enough to have the valves just kiss the pistons. In which case a $250 set of valves and a $350 valve job and you are back.

 

Either way, anticipate bent valves over destroyed bottom end. I would be replacing that cam pulley as well.

 

Very sorry for the "loss".

I ran a dry compression test this evening.

 

Cyl. 1 (df) - 120 psi

Cyl. 2 (pf) - 120 psi

Cyl. 3 (pr) - 120 psi

Cyl. 4 (dr) - 90 psi

 

Not sure if it matters but the gauge didn't hold and slowly went back to 0 psi. (except for cyl. 1. It stayed at 120)

 

 

Isn't 120 low ? I guess it doesn't matter since cyl 4 has a major problem.

 

Tomorrow ill try to run a wet test.

Yes on the low side,. #4 is either bent valve(s) or cracked ring &\or ring land. Does spark plugs show any signs of impact damage.

 

Really don't matter, with #4 being that low. Need to pull motor & disassemble to find out how bad the damage is. FWIW if all cylinders was 120. I would put new TB & run her. But with one at 90 there is something broken\bent in #4.

 

Best of luck

All the spark plugs looked good, no damage.

 

 

Motor has 120k miles so I may has well do all the valves / inspect everything else while its in pieces.

 

I'll have to take it to the shop to get it them done, but I may take apart the manifolds, pullies, etc. so they only have to worry about the long block. Also, the cost of labor would be cheaper.

All of my vlaves just kissed the pistons. Enough to give me a bad leak down. My pistions where actually in great shape still, I may post them up for sale.

Pulling the motor isn't horrible at all. Label everything in bags and mark all your connectors with tape.

120 is not bad for the mileage. 90 is the bad one. You are deff looking at pulling it and disassembling.

 

No one should be interested in buying used OEM pistons. Sorry.

 

No one should, but hey its worth it to post on ebay. lol

 

Good luck, hopefully its just head work and your ready to rock again.
