(H22) I have my head milled 30 thou, and the block has been decked slightly (before I got the motor) and I'm running a stock headgasket. I'm getting the engine dyno tuned next week so I'm getting all the noises and quirks taken care of before I tune it. One of the noises I've found out is the timing belt slapping on the cover from it being too loose (I took off the top cover and ran the engine and saw how much the damn thing was vibrating back and fourth, between the exhaust cam gear and the crank gear). I have the manual tensioner on there, I've done the tensioning procedure 2 times already with no avail. So... is the engine shaved down so much that the tensioner can't pick up the slack of the belt?? I'm using the PE super strong belt if that makes a difference. Also, to make this weirder, the noise goes away when the engine is fully warmed up, but I don't know if it stops wobbling as much as I can't warm up the engine right now.

 

hmm maybe 4bidden has an opinion he was having problems with a loose belt.

 

yes its possible that the tensioner is maxed out the auto tensioner is just that, losent the bolt and its automatticly takes up the slack.

, 30 thousanths on the head and decking the block is taking alot of material off.

i have a block decked 35 thousanths, and stock head, and my timing belt is brand new and the tensioner is maxed out, im using the manual tentioner from the f22/h23, if you find a solution post up,

 

Ok, so you're about as milled as I am then. I fixed the problem, though I don't know if it's 'technically' the right way to do it. Following the tensioning procedure up to the point of loosening the tensioner the second time, then using a screwdriver with the timing covers off, pushed up on the manual tensioner to take up all the slack, then tightened the bolt. Viola, problem solved. Now my engine runs ****, no sounds, freaking perfect.
