2000 Civic Si - been fine since the build and yesterday my wife comes home and the car sounds like ****...sounds like the timing belt was slipping...I removed the valve cover and found this:



"Well there's your problem right there"

Anyway my air compressor worked fine yesterday and now that I need to remove the crank pulley, it will not fire up. I checked the socket and the circuit breaker.

I guess I can't even determine the cause of the problem until I get this:



My guess is the (brand new) tensioner got loose...I guess we have to wait for the tool to arrive...

 

I have that tool, and used two half-inch breaker bars with it. Worked like a charm to remove the crank pulley bolt. I did have a local shop put their large impact on it the day before to break it loose first tho, ok I cheated.

 

Were you running the plastic covers?

I dont know about the build, but if you didnt install the washers correctly behind and in front of the crankshaft gear that drives the timing belt, it will want to walk in and out and tear itself up. Look at your exhaust cam cap. It has disintegrated timing belt on it. Its rubbing.

 

You're lucky it didn't break! The gouge looks like it caught onto something, notice the line? It was definitely rubbing on something, then probably got caught where it's gouged and broke off? And the belt is definitely walking.

Good luck!

 

I flirted with disaster right after my build.

One of the screws that holds the plastic t belt housing to the block shook loose during the early dyno tuning pulls, and fell down to the bottom and started eating the belt.

 

well i am having the crank pulley removal tool overnighted (cheaper than a new air compressor - still not sure why it died).

perhaps i'll have more pics tomorrow.

 

You are very fotunate my friend!

Buy a lotto ticket

j/k

 

where could i find that tool at????

 

I had that exact problem with my belt. My power steering tensioner Bolt broke and the bolt head went into the timing belt case. I had the top half half of the timing cover off for cam gar adjustments. Belt didnt break though thank god

what you could do is leave the car on all four wheels(asuming that its on jack stands), put it on 5th gear and use a breaker bar with an extension and untourqe it. its a bit scarry but it works, fortunately, i have that tool that you've ordered.

 

Damn, look how cheap they have it now, I paid the more expensive price. Make sure this is the right one for you.

that's the one, 33 bucks overnight.

 

we just fixed a customers car (99-00 civic si) that had the same slapping noise and check engine light.

the customer had the engine rebuilt by a 3rd party. the quality of work on the rebuild wasnt very good, as i found many loose and or stripped bolts on the tranny, block and even cam caps.

the 10mm bolt that holds the inner timing cover on came loose and fell down to where the crank sensor is. it got stuck on the bracket and start cutting away at the timing belt.

luckily he brought us the belt right before it snapped. it was cut straight thru in certain sections.

we ended up replacing the crank gear (damaged from hitting bolt), the crank sensor (dented and chewed up), new timing belt, tensioner and spring.

i had to take the cams, cam caps and etc out to clean off all the shavings from the belt.

good luck with your fix

 

can you believe this **** - i paid for overnight shipping on the tool and my wife missed the UPS guy...and the guy didn't leave the package...

anyway, the timing belt is looser than I realized...i wonder if any valves were bent. I do not have a leak-down tester but I do have a cylinder compression tester. i believe i have read in the past that sometimes you get good compression even with bent valves...should I just yank the head and inspect the valves regardless?

i do this, but i jack the car up on jackstands, remove the wheels and pop screw drivers in the middle of the rotors. works like a charm

Had the same thing happen: I was lucky!!!!!!

 

well my camera took a **** on me too so no more pics...but the problem is fixed. the bolt from the inner cover came loose and mangled the crank sensor then nudged by the water pump and melted into the outer cover and chewed the belt.

i just so happen to have those extra parts and got a new timing belt and it's good to go. test drive....
