Thought I had it solved when I pulled this out of the head @ cyl. #2:
But once I put it back together with new O-Rings on the injectors I still have the same problem.
The engine's tired. Compression is 350-375 on all cylinders. Within 25% hi-to-lo but below 400...
Don't think this is the issue since it's hydrolocking. If lack of compression (i.e. not enough for ignition) were the issue wouldn't I have enough blowby to avoid hydrolock? And is there even enough fuel in one proper squirt to hydrolock the engine anyways...
When I started the truck after the new injector o-rings, the smoke was dark grey and wreaked of diesel.
Pulled the glowplugs, and checked each cylinder for fluid with a syphon pump. Didn't find any with the tube bottoming on each piston.
Turned it over using a remote starter lead to the starter solenoid. Cylinder #2 blew diesel out of it every revolution for about 25-30 revolutions.
Could the injector be stuck open, and since the remote starter is pumping up the oil pressure, I'm causing the residual fuel in the fuel rail/galley to be exhausted?
Will a buzz test tell me if the injector is stuck, I don't want to try starting it anymore b/c of the hard stop it does while turning over... so not sure if I can do a contribution test.
Either way if I should run the tests I have to order Autoenginuity or OBD2.
Thinking of just throwing in a brand new AE injector I have lying around to see if that fixes it.
Anyone know if running an AE in any cyl other than #8 temporarily is a really bad idea?
