Hi all, been looking here for a while but now I am in need of help.
have a 1995 vx 24v 1hd-ft diesel
16psi
boost guage
3' exhaust
egt
tranny cooler
radios galore (im in Search and Rescue)
recently when towing my jayco (2500kg) over a mother of a hill got black/blue smoke and a bad knocking noise from the IP area. thought id killed the turbo but still had boost, as soon as I backed off gas it got better after about 30 seconds and we were away again. after leaving a little brown stain in a certain place I thought ??? what could that be. it did it 5 more times getting there. Fuel starvation ?? I cleaned all the lines, filters and took unloaded over the same hill at full throttle. with no problems.
Ahh I though dirty fuel. so we hooked on caravan and went for another to. Then under 3/4 throttle under incline load tick tick tick, bang bang bang and black, then blue smoke. same symptoms as before. I took it to a diesel shop they said the turbo had been boosted from the waste gate to the airbox so could run at max that the turbo could do (which was about 16) we blanked that off and took her for another spin with max boost of 12psi with the same problem under load.
left caravan in Nelson and cruised home to Christchurch very carefully, but this time on inclines and under 4/5 throttle will do the same tick tick tick, bang bang bang and black, then blue smoke. same symptoms as before.
Took her today to a local diesel specialist who said she was running rough at 900rpm and breathing hard with a lot of oil. possible cause a ring scratch or busted block. I thought these were tough dogs, has anyone heard of a block crack or possible causes to this sort of problem. been quoted 6k for a basic or 13k for a new block and rebuild. ahhhhhhhh
Any help is good help.
