Hey guys. So I go the new 308 running in the Mav this weekend but noticed it was a little off. I fired it up this morning and found that with my infared thermometer, that 6 of the cylinders, at the head, were running about 600° while #1 and #4 we running about 230°. I re-checked and adjusted the valves, checked for ignition at the plug and both were good. Any ideas what could be going on here? Thanks!
do a compression check on those 2 cylinders and compare to the others. make sure your head gasket is sealed on that side maybe your sucking in h20. or pull those 2 plugs and pressurize cooling system see if coolant comes out.
Double check that you have the wires on in the right firing order. Does this cam use the new or old firing order?
Thanks guys! I'm just gonna gut the ignition system and start new. I should do that anyway for a new build.
Mine were running around 400 at the header tubes, then one was 250 and one was 180. I found that 2 of my rockers had worked themselves loose. One was still on but only barely. The other was laying off sideways. Then when checking, I had one more (all on driver side, and all intake valves) was coming loose and only on hand tight.
my first thought is that youve got those two cyliders plug wires mixed up. also check to see if there is a vacuum port on the intake that is not pluged up.
