They had been soaking in JB-80 since Saturday. I really should have cleaned it, but I hate washing in winter w/o a heated shop to go in when you are done.
I am all nervous that I will spend $100+ per hole and still not fix my dilution problem. What the heck, it is only money.
Yeah that open air garage, I feel your pain :lol: Soaking isn't as effective as the pressure washer. Putting the head on saw horse and working it from both sides makes them loosen up pretty well. If you are not pulling the head, then (for the most part) you only need to pull the injectors, not the cups. Those normally come out pretty decent with some twist action to loosen them. None of my engines had ever sat outside with no hood though, so they weren't all that bad to begin with. A bad injector is usually pretty noticeable, and you can observe it yourself before committing to dollars. I know, it's a bad time of year, but a bad one will feel different at the line next to the injector. It will warm slower and the pulses will feel softer. Also loosen the vents and pay attention to the engine. A squirter is easily spotted unless all are equally funky. Late timing can also lead to oil dilution. Is it wet stacking?
I spent about 30 min with my tool on the two problem injectors and didn't get the NBRs out, but I did get one injector out. It came out pretty easy with a jar from the puller.
I never checked warmth, but I did notice BAD pulses from 2 and 3 (Where is one? Front IIRC) When you crack the bleeders they sputter fuel out and 1 and 4 you can see a rythmic pulse. I never heard a change in engine performance when cracking injector bleeders.
Hopefully timing isn't a problem, but I doubt it has been timed in a long time. Wet stacking doesn't seem extreme, but is certainly present. ie waiting in line to tractor pull or waiting for a full chopper box when the haylage stinks.
