How to set timing on a Toyota 3.0 engine?
Set it with the timing light
I recently had to replace my water pump 1991 Toyota pickup v-6
3.0 3vze engine more than i bargained for!!!
everything was going smooth....until I moved my cam!!! woops
what you have to do is make sure both cams are pointed at the
marks/notches on the back timing cover...the left one might be
pointed a little more to the left of the notch, and the right one
may be pointed a little more to the right. the crankshaft has to be
pointed at 0 degrees... the only way to be sure this is done proper
is to turn the engine twice... use a socket attached to the
crankshaft and turn it past the 0 degree mark once, until it comes
back again (the second time) both marks on the cams need to match
up exactly the way they started... next set a inductive timing
light to number one cylinder, and gap the diagnostic terminal under
the hood (use a paper clip and connect the e terminal to the te
terminal (check manual for this, some years you must detach a
vaccum tube!!!) after this start the truck, put the timing light on
the crankshaft, and measure the timing... timing should be 10
degrees BEFORE top dead center (0 degrees) this is at idle (~700)
if the engine is turning faster than this, the timing will be
different.. best of luck and make sure the terminals are jumped!!
otherwise the engine will try and compensate for the
