Sun, 23 February 2003 09:45 ok, time for ed's dodgy box of cheap ass ideas to be re-opened... i would really like to get new cams to support all the headwork ive recently done, but alas, getting the cam faces welded and reground is a *tad* expensive. so, ive been thinking how i could get away with simply regrinding my existing cams, and figuring out some way of dealing with the reduced lobe base circle dia... so, im thinking, say i grind 2mm of the base of the cam lobe. to compensate, it seems possible that i could whack an *extra* valve shim UNDER the bucket, thus pushing the whole bucket assembly out of the hole some 2mm. as the etra shim would be about 3mm thick, i'd also have to grind the valve stem down some ~1mm to make all the clearances correct spec. give the rest of the cam grinding id, be doing, i cant imagine id be increasing lift to over 8.8mm or so, and the profile wont be to steep, so hopefully i wont be facing shim spitting issues (for the top shim). question is, can anyone see something terribly WRONG with this idea? is the 'under' shim going to be prone to dislodging (i cant see thats possible - its a tight fit for it inside the bucket). is it potentially BAD for the bucket to be protruding an extra 2mm? (theres still A LOT of bucket inside it bore) heres an image of what i mean... 30k big any thoughts at ALL as to why this wouldnt work would be appreciated. as too a pat on the back for this being a potentially UN-stupid idea cheers ed [Report message to a moderator]
