check cam timing again and make sue ur using the right marks on the cam spocket ( the two arrow that points toward eachother)

Re: timing belt broke.... now problems :(
 

dont z6's and y8's have different belts? i have never had a y8 so i dont know for sure, but if you had the wrong belt then that could cause a problem. i think i remember reading to use the belt for the head. dont take that as fact, just use it for research

Re: timing belt broke.... now problems :(
 

ok so i did the compression and it was 159-160 on all four.... I am using the y8 timing belt... and i have drove it and then check the timing again and tdc with rotorbug pointing at plug 1.... Also the marks on the cam line up and the bottom pulley is in between the three together.... now the timing belt is a little loose... But i dont think it is loose enough to slip.... i had a problem with the tension pulley tighting the belt up...... i had to puch up on the it from the bottom and tighten the damn thing up to make it tighter... Isn't the spring suppose to do this?? i didnt have luck with the spring, so that is why i did the pushing up thing.... Is this a bad idea to push the tension pulley up and tighten??

Re: timing belt broke.... now problems :(
 

no, make that bitch tight. the spring wont do near enough. also, check your ignition timing. that will let you know if your cam is off

Re: timing belt broke.... now problems :(
 

thats ur problem, it it the WHITE mark on the crank pully that indicat the TDC.

Re: timing belt broke.... now problems :(
 

Ya there should be one by itself that indicates tdc. Also its a D16Z6/Y8 so there's only one cam gear. The arrows can't be pointing to eachother.

Lign the white line up and point the cam gear up.

Re: timing belt broke.... now problems :(
 

Well it does have arrows pointing at each other... there are two... one on each side of the cam on the cam cover. :)

Re: timing belt broke.... now problems :(
 

there are 2 lines that you line up with the top of the head where the valve cover sits. then there is the word "up". line the marks up with the head and put "up" to the top bring your crank around to top dead center put a y8 timing belt on and make that bitch tight. you should be good to go then

Re: timing belt broke.... now problems :(
 

bingo...youre 16 degrees off or whatever that middle mark is

I took it to a shop and they said it was perfectly in time... I changed the fuel filter.. But didnt help at all... Now it idles great just sometimes when i hit the gas it bogs out, likes its not getting enough fuel... I was thinking maybe my fuel pump is going out or maybe the Vortec FMU im using is messing up on me. Any other suggestions???
