need urgent help with timing belt
just doing the klze swap today, had some friends helping out, two of them decide to pull the timing belt off, the pistons were not set and neither were the marking on the cams, now i need to know where the markings are on the block. the cams have little paint marks on them, the rear one has two little triangle marks on the block and the front has nothing that i can see. need to have this motor back into the car by sunday morning so help would be appreciated alot, thanks.

Re: need urgent help with timing belt
Well, just set the engine to TDC (top dead center) meaning piston one is all the way to the top. It should be marked on the block. you can also use a long straw and remove the no 1 plug and putnthe straw there to check when the pistomn is up. Try not to turn it alot o.0 since valves can be bent. Also..why did ur friend do that? was the belt old?? make sure u align al the timing marks. Get a manual (book) for this car!! even better..get someone that knows very well (mechanic) to set it to correct timing. DONT crank the engine. it will bend the valves. If you do bend them ..sell me ur shoft block :p ha jk. YEah just align it properly.

No. K series engines are 'non interference' engines, so even if the belt snaps at full blast, you shouldn't damage any valves or pistons.Originally posted by hgallegos915:

Re: need urgent help with timing belt
honestly, the valves wont hit the pistone, i broke my timeing belt at over 8,000 rpm. all i did was replace the belt, i still drive it every day to work. i just put a long clean piece of wire in the no.1 sparkplug hole and useing a socket roatate the engine until it was at its highest point. but there is a little mark on the crank that will tell you when its there. i wish i knew that before. oh and be sure to line up the cam pulley marks too

Re: need urgent help with timing belt
You still need to figure top dead center, because every other time that mark on the cam lines up, it'll actually be 180 degrees off TDC.Originally posted by goldy1:
