I believe one of them shows TDC on #5. Not sure why though. It's easy enough just to mark both with white paint, and put the timing light on #1 - you'll be in the right ballpark. However, if you're trying to drop your distributor in, you need to know when #1 is at TDC. For this you need to take off the RH rocker cover, and take out #1 spark plug. With the aid of a long screwdriver dropped down the hole, turn the engine until the piston is at the top of its stroke. The valves on #1 should have a small amount of play in them (ie they're set for firing stroke). If they're "on the rock", you need to rotate the crank by 360 degrees. When your screwdriver looks as if it's at the top of its stroke, look at the crankshaft pulley and you'll see one of the notches close to 0. Put it at 0, and drop the distributor in so the rotor points to the little mark on the casing Martin 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!
