just replaced the head on my 91 integra, w/rebuilt head (both pr4 castings) car started perfectly 1st try, i removed the valve cover for other reason later & discovered my timing belt appeared to have walked 1/2 way off the cam gears! & the gears had rubbed hard on the inner cover, upon further inspection i discovered the camshafts are a 1/4 inch shorter than the originals, so the gears are closer to the engine! making it impossible for all the gears to be lined up for the belt, does anyone know if older or newer tegs have shorter cams? help

 

Cams were all the same sizes, the only difference is from 90-91 they had a 130HP to crank.

The revamped the cam profile in 92+ and the motors started making 140chp.

Profile isn't length, its the actual cut of the cam.

 

thanx rajin, then what the hell can these cams be from! they are a solid 1/4 inch shorter, even with a new inner cover wich isnt warped @ all, the gears are up against it (the new cover) and you can clearly see all the gears for the belt dont line up w/ it! im lost here and the head is definetly the same pr4 casting, any ideas? i would use my old cams but one had siezed in the old head so is not an option, help

 

I have a set of actual used B18A cams. I'll get them sent to you for a pretty low price.

Just PM me.

 

i might do that, if i went to pick & pull how do you identify the 130hp from the 140hp? thnx
