missfiring woes
Hi ,
Need some help if possible.

Wife was out driving 110 TD5 when sudden loss of power and lots of grey smoke. Managed to limp home and get onto drive .

At this point no missfire, engine seemed to run o.k. and rev fine just what I asume was unburnt diesel ( not a lot though)

Conected the lync diagnostic and there was an error associated with injector 5. and a few relating to things not actually present on the truck.

Cleared the codes and started again ... again no missfiring and some grey smoke.

This morning went out started again. this time, clouds of grey smoke and definite missfire.

Checked fault codes ... none

Fairly good at diagnosing petrol engine issues, but diesel is a completely different world

where do i start to figure out which cylinder is at fault?

I’d start with new air and fuel filters. How old is the fuel filter?

Any odd fuel pump noise recently?

When did it last have an injector loom? Have you checked red plug?

o.k

Had an issue with bad starting a couple of months ago
so
changed fuel pressure regulator and checked pressure, 4 bar
new glow plugs
new fuel filter housing
new fuel filter
new injector harness (land rover)

red plug clean no oil

At mot, told local garage to change injector seals .. and all of the bolts holding what i'd call the rocker shaft sheared. Had a 10p TD5 in the garage so they took the head of that and put that on, with its injectors, dont know if they changed the injector harness at that point or used the one in that was in there. They were a bit timid about changing the seals on that head (understandably)

Air filter was changed a month ago


New fuel filter few 100 miles ago,
fuel pump sounds good
did change injector loom farily recently Santa - 1977 Series 3 - new chassis, tub, disc brakes,SU Carb

If they used the other set of injectors did they code them to your current ecu?

yes they did,

The missifre was a red herring. After running for a bit it went away. However, checked the oil level and was damn near empty. Since 2012 this engine has hardly used any oil and just had to put 5 ltrs in it to get it to the max level.

Still loads of white smoke though and no erro codes.

Thoinking thst the turbo might have gone south. revving ther engine and squeezing an intercooler hose produced hardly any push back from the squeeze Santa - 1977 Series 3 - new chassis, tub, disc brakes,SU Carb

Sounds like the turbo is burning oil. Take the pipes off it and take a look.
