Hey guys!! i finally got my celica on the road as u all may know, and now i am to the point of replacing the timing chain.
Went on beautifully, all the cams stayed in time etc, maked it all and still runs good. Just now i have a VERY annoying bad sound comming from the rocker cover. Sounds to me like a valve tapping of some sort. But the timing chain rattle is fixed. Is it possible that due to the engine being run on a timing chain that was 1cm longer (streched) than the original, and therefore the cams not workin on the exact time, that one of the cams could have been worn in the wrong way? causing this tapping now that its back in time with hte new chain?
Any other ideas? Valves wouldnt be effected by a timing chain change i wouldnt say...considering it still runs smooth.
But i havnt got an 18r-g book. Could someone scan a couple of pages of specs for the valves and stuff? or post.
I need the valve clearance, (yamaha head)
And whatever else info u might know in help of fixing this problem. I swear if i blow this motor for some unknown reason ill b sooo pissed.  but all ideas would be greatly appriciated.
Cheers
Steve
