so i was changing my timing chain ten. and when i went to push on the chain guide to set the tensioner i snapped some of the nylon off it,can i get the side cover off without dropping the motor seems close to the frame, also i doubt it but does anyone have a chain guide

How does this help him?

 

yes u can pull the cover off without droping the engine just pull the balancer first

 

the side cover can be taken off without dropping the motor but I had to take the top engine mount off and lower the engine enough to get the water pump bolt out because it is very long and will not come out fully without lowering the motor.

 

ok so i found the chain guide part number and i have to replace the balancer bolt and camshaft sprocket bolt,also when timing what colored links on the chain go where

 

The links are not the same color for all ecotec motors.

On the crankshaft pulley with the timing cover on the motor there is a timing mark at 10-oclock and a notch on the crank just like old school if you line these up your at TDC. Then go ahead and pull the timing cover off and the crankshaft should have a white dot on the sprocket pointing to 5-oclock if you lined the timing marks up. On top the exhaust cam should be set with the exh mark at 10-oclock. The intake cam with the int mark should be at 2-oclock. The colored links will then need to be lined up on all three marks, in a nut shell this is what you’re looking for. Taking the tension adjuster out will still not give you enough slack so by removing the cam sprocket and placing the chain on it then lining the sprocket back up with the chain on it will make it easier. the crankshaft pulley bolt and cam sprocket bolts need to be replaced and tourqed accordingly.

 

take off FR wheel, remove plastic, remove crank pulley and i think the tensioner pulley, remove side plate. its easy

got the timing down seems pretty easy, do the cam gears only go on 1 way?
also what should i use to release the timing ten. so i don't break the guide again
last is their anything that i can upgrade with the cover off

 

the cam gears are keyed and only go on one way. Both gears are EXACTLY the same so theres no mixing them up. To remove the tension, you will have to remove the timing chain tensioner by screwing it out (located on the back side of the block, passenger side. takes like a 1.5 inch socket). After that, i just removed the chain by taking the cam gears off first (be careful of where the rollers are located on the cam making it want to spin. just keep your fingers out of the way). As far as upgrades, I have some high performance GM racing cams for your car. I bought them but Id rather spend the money on a clutch.

no need to take the tensioner out....i actually took my head out today....i smashed my hand twice trying to get the dam tensioner off and said **** it....so i took all the caps off the cams and took a 24mm and stuck on the intake cam near the sprocket and i twisted it back and boom it popped out....much easier and i didnt smash my hand again....lol.....but i guess you need to take it off anyway to get the timing right...well good luck....i cant remember off the top of my head what size bolt that is...but i think its a 27mm for the tensioner....or get a big enough crescent and put some ez grip (aka some kind of grippy substance like spit and dirt....lol) and you should be able to get it off fairly easy....just hope your tool does not slip when your getting it off

 

i love how you have one more line in your paragragh than i, but contributed no more information to this thread...and turned what i already stated into jibberish.

 

1 1/4 inch socket with a long breaker bar will remove the tensioner.

 

whats the easily was to release the timing ten so i dont break the guide again

 

turning the engine over by hand (wrench on cam bolt), made mine pop in basically as soon as i moved it a millimeter

 

why does the engine need to be turned over to release the tensioner

 

383 was referring to the spring release to retension it

1 1/4"(32mm) and a breaker bar

 

i thought all you have to do is move the tensioner back 2mm,what does turning the motor over obtain??

 

aww thank you...i could not remember wat size it was...thanks for the verification
