Smoke

[Rudolph]

Hey guys

Does a lot of blue smoke when cold signify piston rings are finished or injector(s) are finished?

[djsdiesel]

what year?? how much milage? ever had injector o-rings replaced? is it using oil? does it start hard?

[Rudolph]

It's 1997 250. 187000 kms. (though many idling hours). Never replaced injector o-rings. It does burn oil. It is hard to start when cold.

A lot of idling is believed to hurt your truck and cause wet stacking. Wet stacking is fuel residue buildup.

i would bet on injector o-rings being bad

[Clay Henry]

You said it uses oil, how much does it use.

[Rudolph]

In about 2000 km of driving it's probably used about 2-3 liters of oil. But it also leaks a lot of oil out of the crankcase breather on top of the driver's side valve cover.

[Clay Henry]

2-3 liters! Dang thats alot of oil brotha....i don't know how uch your leaking but your obviously burning some too i think. Have you done a compression test?

[Rudolph]

I haven't done a compression test because you need some special tools and pressure gauges.

If my oil smells a lot like diesel and the truck smokes a lot, could that also mean injector o-rings?

Hey at least if my truck uses & leaks a lot of oil and I have to add a couple liters every few thousand k, I'll never have to do an oil change.
