thanks, i have done it as per the above but still no joy. is there somewhere i can get a copy of the manual

Nissansilvia.net
or just google it
timming dots need to be 11 links apart
with lobes pointing outward on both cams

sawyers bay motors · 06-11-2012, 02:40 PM

do you have a diagram. does the crank need to be set at TDC? what i have seen on google is:

cam
there should be 3.5 links after the mark on the exhaust cam
10 links between the exhaust and intake
and 1.5 links after the intake cam mark (looking on eye level with the head)

Is this correct?

sawyers bay motors · 06-11-2012, 02:52 PM

JDMRIDDAZ · 06-11-2012, 03:03 PM

Yeah you're using the motor with the distributor right? So pull signal off the no.1 spark plug wire and make sure you got the gun hooked up right and the gun is in good shape too haha.
