Ok, back in town. Truck fires and runs but I got two injectors not firing. 3 and 4. I switched injectors around and it's not firing the proven good injector. Changed the new valve cover gasket/ harness for fear it was bad out the box. New harness still not firing 3 and 4. So I'm thinking IDM???? I replaced everything else on this thing So why not this as well. Thoughts?
I probably shouldn't have done this but I also tied a jumper wire from the IDM harness to the harness just before the plug to the gasket/ harness. No change. I then wired the new harness plug that came with the new gasket into the harness. No change. The IDM I purchased ,I actually drove three hours to pick up they told me no flash...... Is it possible they are incorrect? I found it unlikely a co. that remans these would be wrong.
I bought one that said it would do a 7.3 but it wouldn't do the job. Need one specific to the 99' and up so I've been told. Have I been misinformed? I am ordering one tomorrow so I should know. Runs good smooths out at 1300 rpm but still low on power. No noise other than the thump thump of a dead cylinder. Valves are opening as well. I know this can be solved.
Once up to temp, how much blowby comes out the oil fill cap?
You just need a adapter for a 7.3 powerstroke. Not year specific. It is a tight fit. Google/amazon/ebay "7.3 powerstroke compression test adapter"
Quite a bit. To be honest I don't notice any difference in blow by, but I could be wrong. I always thought there was a lot of blow by but the motor always ran strong.
Not sure if it matters but I have no fuel in the oil and every time I cleared that cylinder through the glow plugs hole it knocked the valve cover over with the residual oil in the cylinder.
