Ok so iv nearly finished my rebuild (just stock parts really), just trying to fit the timing belt but im scared of getting the timing wrong and ****ing up all my hard work.

Whats a precise reliable way of; finding TDC, keeping it there and getting the timing belt on, then after that how do i know its all good?

any help much apreciated

thanks in advnace

 

Well the motor should be at TDC before you tore it down and after you rebuilt it, including the valve positioning....

You should also have a manual showing you where your TDC markings are... Either way on the crankshaft there is a mark that needs to line up with a mark on the block.

As for the cams if you’re using stock cam gears there is a mark on head gear, they align at 3 o'clock and 9 o'clock pointing at each other. The cam lobs should be positioned proportionally on 1 and 4 cylinders as well...

When installing the timing belt you rout it from the crankshaft to the water pump intake cam exhaust cam pulley and back to crank.

Once on you should rotate the assembly counter clock wise three times, feeling for any faults like a piston ring catching or valve touch a piston. After the third revolution everything should return to the original position and the belt should be tight enough to torque down your pulley bolt...

p.s. I like to back my valve adjustments all the way out, once I'm confident I adjust the valves according to the manual, then rotate again feeling
