supra head gasket questions+ rebuild

Another thing worth checking is that cam pulleys are bolted to the camshaft correctly; they should be mounted with the dowel pin in the middle hole. After you have bolted it on and you need to line up the match marks for timing, rotate the pulley and the cam together.

hi bill, still problems was 180 out corrected that and drove round the block this was timed on cylinder 1. cylinder 6 just wont time. still lumpy

cylinder 6 is at the back of the engine number 1 at the front no one else as ever heard of timing on number 6????

did you time number 6 yourself or did someone else do it?

No one touches the Supra except myself, I've set the timing dozens of times using # 6 as stated in document below. (# 6 is at the back) if you have a variable setting on your strobe light set it at zero. It sounds if you may have a doggie HT lead. Does the timing advance when you remove the terminal link in the diagnosis box.

Also make sure the arrow on the pick up clip that connects to # 6 HT lead, is pointing towards the spark plug.
