2.25 diesel smoke?

**Muckinhell** · 29th January 2010, 07:22 PM

could the smoke from my 2.25 be related to the fact that it doesnt have a muffler or any exhaust other than from outa the head down and under the pass foot well? would appropriate back pressure help with a full system in place?

no, odds are you are seeing the normal cold combustion smoke,

Fozzy smokes like a chimney when cold and idling but once you get some load on or warm it up its gone instantly.

they all blow a little smoke on initial start up.

If it has been sitting for a while there is a good chance the valve stem seals are hardened and not sealing, which could lead to a lot of smoke, particularly if it has the butterfly in the intake to provide vacuum. (The vacuum sucks oil down the valve stems)

it prob had been sitting a while before i got it but alas no vacuum butterfly either.

if it clears when you start driving (have a passnager watch it) its not too bad.

changing my shoddy injectors helped but I suspect my current batch of fuel isnt.

Diesel heads are prone to cracking you could be geting water in the combustion chamber. Have you checked the pump is timed correctly?

If it has been sitting for a while or not used a lot the fuel may be off.
drain the tank and put new fuel in. Diesel don't last long.
It probably needs a good run to get up to temp.
take it for a good run and work it hard with a load on a good pull.
They like a good workout now and then.

Mine was the opposite it had a bit of a restrictive muffler on and smoked a bit too mutch .
I put a Walker straight through muffler and it cured the smoke down to just a light haze.......Mark
