hi guys I have a have a 1996 psd with 198,000 miles on it
a week ago i when to a friends house and lit it idel for about 15-20 mintes as i left the biggest cloud of smoke i have seen came out of the exhaust it was so bad you could not see the house behind you but it stopped after about a half mile
and did not give me any more problems until yesterday it stared to smoke again now it smoked the worst at a idle but when you are at 2,000 rpms or higher it does not smoke
i am stumped
any help


3in downpipe
5in exhaust
k@n air intake
superchips
spooled turbo

 

White smoke is unburnt fuel. Excessive idling will cause white smoke
if the engine temp drops too low for complete combustion.
Get A hotter thermostat (203F). Adds a little Performance too.

BTW:
Blue smoke is oil
Black smoke it too much fuel.

 

if i dont wait for glow plugs or my gpr isnt working properly i get lots of white smoke on startup.

 

It will not smoke until you dive it for 5-10min
You know it bad when i will not even dive it on my farm. The inside of my exhaust looks to be caked in oil.
i was thinking valves. i pulled off my valves covers (just messing around) and the are spot less.

 

Injector O rings are bad maybe

 

Check the base of the injectors for bubbles while running
at normal temp.

Does it run OK when smoking? Missing, lack of power ect.
Are you loosing coolant?
Is it running hotter than normal?

Check your coolant bottle for engine oil.
Check your oil level, high or low, and for coolant in the oil.
I agree with waljon, It could be injector o rings
or injector cups.

 

FYI my Injector O rings are shot and they have been getting slowly worse over the summer my symptoms at first were smoke like you are talking about and oily residue on the tail pipe just like you I still do not have any mixing of fluids or some of the other symptoms that go along with it .

This summer I put a 203* stat in and it kinda got rid of the smoking thing at Idle now my exhaust is just real black and sooty.

 

it runs perfect when smoking. no loss of power or missing. i am hoping it is the injectors because i ordered stage 2 160cc injectors 4 days ago but i do leak coolant from around the oil filter but it does not appear to be in the oil
i am going to try 203f thermostat.
