Great info Duncan. Thank you for posting that. I will leave my pump alone for now. I did notice the #1 injector had some compression blowby at the base of the injector. My new seats must not have sealed all the way. Will have to pull it and install a new seat.
Has anyone had better luck...
When injector pumps gunk up, where typically does this occur within the pump? I would think the delivery valves. Can you unscrew the delivery valves and clean them while the pump is still on the motor? Do they take special gaskets or seats like the injectors do and are they serviceable like...
OK, big progress today! I did a Diesel Purge using the Liqui Moly brand. Unhooked the fuel feed line from the tank and dropped it into the Diesel Purge can. In about 2 mins my idle cleared up nicely, about 10mins in no smoke at idle and rev'd real smooth with a bit of black smoke at WOT...
Duncan, I hope it does show a leak. Then I would at least know where to focus. Will try a warm engine compression test next. I would hope the Hi-Tech injector folks out of Australia I used set the Pop pressure correctly. I will see if any local shops can pop test them. If not a head leak...
As suspected, it still runs the same. I bled the fuel system until fuel was pouring out of the filter, inj pump and injectors. I did have a productive day though and replaced the axle bump stops and all motor/trans mounts. One was broken badly.
I guess I will just wait for the head gasket...
OK, went out and re-torqued the head bolts to 103ft/lbs in the order the manual shows. They were all right on but 2 towards the middle that took about 1 turn to reach full torque each. Going to fire it up to see if any difference but not confident there will be. Will bleed the fuel system...
I let it idle about 2 mins and then shut it down since it was smoking pretty good. I live in the forest and did not want my neighbors thinking there was a fire. I put a brand new thermostat in it just recently as well when I changed the radiator hoses. Mine is fully manual glow now so full...
I fired it up today and took the oil cap off. No pressure coming out at all. Waiting for my head gasket leak detector and will check that next. If I post glow at idle, it idles really smooth. Once I let off the glow, lumpy and low idle again.
It ran OK once warmed up but still lower power and a lot of sputtering. Will have to try glowing while accelerating. If I glow while revving parked, it seems to help a bit but not much.
BTW: I am reading your Old Landy post. Very interesting read.
The intake butterfly appears to be operating correctly from what I can tell. I replaced the accelerator cable and adjusted it per the manual. It is in it's most closed position at idle and goes wide open with the accelerator pedal to the floor. I have a slight slack in cable at idle. Do...
