PRV has a nifty way of locating TDC cylinder 1: Are 2 plugs on top of the engine. One farthest from the "front" (closest to the flywheel) is used to locate #1 TDC. Rotate the engine to within 20 degrees of TDC via the timing scale. Remove that plug and insert a foot long 5/16" (8mm) drill bit through the hole. Bit will rest on #3 or #6 counterweight -- can't remember which -- into which an 8mm indexing hole was drilled at Douvrin. Rotate the the engine until the bit drops into the indexing hole. Engine is now at absolute TDC #1. Be sure to adjust your timing scale accordingly. This is a factory procedure BTW.

Once it is at TDC you set up your distributor. -Dani B. > #5003 > To address comments privately to the moderating team, please address: moderators@xxxxxxxxxxx For more info on the list, tech articles, cars for sale see www.dmcnews.com To search the archives or view files, log in at http://groups.yahoo.com/group/dmcnews Yahoo!
