The timing belt on my 01 prelude is shreded.. I heard a grinding noise and removed the valve cover and found 2 bolts that have a 12mm head on them and are about 2" long grinding against the intake cam gear and wedged against the cover on that side..

Any idea where these 2 bolts could have came from? This is on a 01 SH engine..

 

The only bolts i remmember being near the camgears are the two that hold the rear cover to the head. Take pictures of what your talking about and what you saw.

 

They were up at the cam gear but that might not be where they are from.. Not sure yet.. ill take pics..

 

bolts that hold the cam gears on are 12mm are they not....and about that length?

K

 

The bolts that hold the cam gears are 14mm.. The bolts in question are about 2" long..

 

isnt the auto tensioner held on by 12mm bolts? and they are about 2" long i think.

yup, 12mm head....then about 1.3 inches unthreaded, and the other .7 fine thread, bolts should be gold....

 

If the 2 bolts are indeed the ones from the autotensioner, you had some serious failure there. For those bolts to come out would mean the autotensioner fell off. Good god the disaster.

 

booo sketchy helicoil time hooray beer

 

Naa.. I remove everything from under the timing belt cover.. The tensioner and everything else was bolted on perfectly.. The timing belt was chewed up but it was still on there and tight..

What size bolts hold the back of the cover on to the head?

 

****.. I looked at a diagram and the bolts that hold the rear of the timing cover on to the head arent the bolts that I found..

Any more ideas here? Im going to take pics of everything tonight and post them up..

 

man...all this time youve spent already you couldve figured it out...pull the timing covers off...or do you not have a pully removal tool??

Uhh.. The cover is off and everything under the timing cover is removed.. I dont know where the bolts came from, thats the problem..

 

my b...im dumb

 

well lets see here....all the timing cover bolts were in tact? And the tensioner bolts?

Is the motor obd2?? If so, are the bolts that hold the oil pump pickup sensors in place??

Yes its obd2.. All the bolts for the CFK sensor are there(their 10mm btw).. I cant seem to find where they go.. Ill look more tonight and post up some pics..

 

honestly start counting bolts. because aparently you have some extras.

 

something doesnt sound right in here, im curious to see if those 2 bolts even belong in that area.

 

yea thats what im thinking..from my conversations with him...i cannot even think of anymore bolts in there..i cant wait until he figures it out cause its gonna be some sort of learning experience

 

its the two bolts on the bottom side of the motor mount. i had the same thing happen.

Im gonna put it all back together tonight and im gonna locktite/jbweld/weld those bitches in..

Thanks again for the help there..

 

DIZZAM didnt even think of those...hmmm i hope mine dont do that

 

this is not a comon occurrence from the best of my knowledge. the little bolt actually came up on top of my cam gears and got lodged in the far back corner aginst the valve cover. it actualy cut my timing belt in half.

Yep.. Same thing that happend to me..

 

How in the hell would those bolts end up on top of the cam gears? One would think they would get caught down by the crank somewhere and cause catastrophic damage.
