Type S Prelude Head Upgrade questions/weird cambelt wearing - Honda Prelude Forum

Vanadium · 03-12-2008, 11:42 AM

I have brought some skunk2 stuff for my car:
Stage 2 pro cams, cam gears, ti retainers, Pro IM and TB.

Is there any chance of type s piston vs valves with my new cams assuming its all installed correctly? as its 1.2mm more lift on vtec lobes compaired to type s cams.

Another question, I have had really bad cam belt wear...
when I got my cam imported from Japan it had the cam belt incorrect installed (exhaust was retarded by one tooth), this was refitted.
I took my car round a track and I could hear some funny noises comming from cam belt area.... so I took cam cover off and noticed that the cam belt had half worn away... its like the cam belt is trying to slide off the cam gears!!! WTF!
has anyone else had this ?

The strange thing with this cam belt wear is my bb4 did the same thing... just not as bad! bb4 ate about 1/3 of the cambelt.

Has this happend to anyone else? > how do you fix this?

Will upgrading cams make this problem worse?

I read somewhere that autotensioner is CR*P so I was planning to convert to manual h23 one.

Thanks all for reading this, any help will be greatly apreciated!!!

Using S2 Pro cams without degreeing them is a big no no.

ok, the wearing is on the engine side of the cam belt, aswell as a chunk removed from the flat face about 2cm in size with a 1cm space and then another chunk continuing around the cam belt!
I have taken the head off, and when removing this I have scared the block flat facing, does this need to be smoothed out before refiting of the head? Its not bad, well it doesnt look bad to me....

Thanks Jade
