well the cam has nothing to do with the cam gear and belt...other than holding the gear on. you put that lil pin inside between the camshaft and the gear right? if the belt is not tight, its the tensioner. Either it broke when you were removing everything, or the shop doesn't know how to work it. its an auto-tensioner.
I need TP for my bunghole

Rep Power: 300 im not sure what they did becuase i was not there today(had to work) but they called me once they got it installed and thats when they said there was a problem
they said they thought it might be the springs or something.
little pin? i will have to ask.
so this is not a comman problem?

Rep Power: 281 May be the timing belt not put back right??
I mean if engine worked right before install, then nothing should be wrong if you put everything back. Unless of course something got physicaly broken when assembling/dissasembling

Rep Power: 812 no it wouldn't its just to make sure the camshaft and gear stay connected and move at the same time. when i go home from work in a couple hours i'll try and get pics up of how you put the belt back. just take them that because they obviously have no clue how it goes on.

Rep Power: 812 pics dont really help so i'll just describe it.
Once everything is off...
set the crankshaft to top dead center (TDC). Align the TDC mark on the timing belt drive pulley with the pointer on the oil pump
set the camshaft pulley to TDC. The UP mark on the pulley should be at the top and the tdc marks on the pulley should line up with the top edge of the head.
align the holes on the tensioner pulley and tensioner base and insert a 3mm diameter pin into the holes.
loosen auto tensioner mounting bolt by 180 degrees.
move the auto tensioner to remove tension in the belt.
install the belt in a counterclockwise sequence, starting with the drive pulley, then the tensioner pulley, then the water pump pulley, and finally the camshaft pulley.
install the crankshaft pulley. rotate the crankshaft pulley two turns counterclockwise so the timing belt positions on the pulleys.
set the #1 piston at tdc.
tighten the auto tensioner mounting bolt to 33 lbf*ft then remove the pin from the auto tensioner.
remove the crankshaft pulley.
install the crankshaft position sensor (CKP).
install engine mount and lower timing cover
install the crankshaft pulley after oiling the bolt. tighten to 181 lbf*ft
rotate the crankshaft pulley so its TDC mark lines up with the pointers.
check camshaft pulley marks. if they are not at TDC, remove the belt and start over.
install upper timing cover, connect camshaft position sensor and tdc sensor and install grommet.
install upper bracket and tighten the nuts.
install valve cover, coils, alt, ps, splash guards, wheel.

^^^ Its not the mechanic its caused by the valvesprings. Sorry i didn't see this post before but in my cam dyno post i posted how to fix this and why it is caused. Sorry about not seeing it yesterday

Rep Power: 324 just a note. the pin is only used on a new tensioner. also I don't see the tensioner spring mentioned anywhere in those instructions. make sure that it is installed.

After this when you are ready you must just tighten the belt to where you would like and bolt the tensioner where the timing belt is firmly tight. After this you will no longer have problems with the belt becoming loose. The reason you must do that is because the valvesprings are a lot stiffer and stronger than the stock ones and the stock tensioner cannot take that. I learned this the hard way because my belt kept coming loose until finally i bent a valve. Let me know if my explaination makes any sense if it does not i will try to take pics or try and make a diy.
