2.25 Blue Smoke: Injectors or pump timing?
I'm new to this forum...good to meet you; thanks for having me.
I've got a 109" 2.25 diesel (+0.060) that smokes blue and smells of raw diesel.
Big surprise 'eh? When I first got it the smoke was real bad; clouds of white / blue smoke thanks to a cracked head. I've since replaced the head, honed the cylinder bores, replaced the radiator, water pump, hoses, heater plugs and such. It runs much better now, but still seems to puff blue smoke and the exhaust smells real rich. Gets about 18mpg avg.
The research I've done (inc. the Land Rover Service Manual) points to bad injectors or pump timing. Any way to diagnose which?
If it is the injection pump timing; can you simply loosen the pump and lines and twist to adjust like a distributor? If so, which way is leaner?
If it's the injectors, I'll have them rebuilt.
I'm just not sure how to tell what to work on...both?
