I also just reralized I forgot to drill and tap holes for the oil pickup mount.


You shouldn't need to drill them.... they should already be drilled and tapped. You will want to clean the threads, though - with nothing in the holes, they tend to get carboned up a lot. It takes an 8mm x 1.25 tap.

I was under the impression that seq. inj. gave a little more performance , as in lees pollution and a little better gas economy . In 90 CA dropped the EGR . I thought this might be cause emmissions and milage are improved with this system. Maybe thats just a CA thing. Mine is from back East so its a fed. ECU. I run alittle richer , I think.


Sequential port injection does give a little better fuel control and economy, but not much. It also requires a more complicated ECU with an injector driver for each cylinder and a camshaft position sensor. The next version of MegaSquirt reportedly will have sequential injection.

I think all of the '90 3.0L Montero models had no EGR.
