Having trouble with diesel motor

Post by **bugshifter** » Sun Mar 08, 2009 10:31 pm

I have a LN106 2.8 diesel. When starting it bangs into life as if the timing was out but seemed to run fine when going . i had a new timing belt fitted but that never helped as the motor was a little tired i replaced it myself with a 5l motor and fitted the new timing belt and tension er . I aliened all the timing marks and all seemed good. Over a few days of driving the original problem of very rough starting came back. Yesterday i started it in the driveway backed out and reversed in and stopped the motor. A couple of hours later i went to start it and would not start and when it did it sounded very tappy. Anyone have a guess at what might be wrong

Just a guess off what you've said, but it could be a fuel problem, ie dirty fuel, blocked pickup and/or lines. If it's only a starting problem, and it runs fine other wise it may be a glow plug issue.

It turned over normal and started quick but did not start smooth

There was only a small puff of smoke at start Not a lot

The glow plugs were tested by the mechanic that did the timing belt

Think fuel must be the problem as its almost the only common denominator between the two engines.

Thanks for all the replies it helps to get a few ideas

did he check the power going to the glow plugs? could simply be a relay starting to crap out which will be the same relay as you used with the old motor.

Well it was a timing issue not sure why both motors had the same problem but the guys at Diesel Australia in bris got it all sorted for me.
