what TDC did you have it at? id have to research it, but there are two TDCs, one on the compression stroke and one on the exhaust stroke. iff the top of my head, you need to do it when both the cam sproket and crank sproket have their respective lines pointing at a little line on the block, its roughly the 1 oclock position on the crank, and 11 oclock on the cam, but i havent done it for several years now.
i assume couve researched the procedure???
whatever you do, DONT drive it to work tomorrow
