Title: 2.25D smoke on starting
Post by: Singlefin on March 16, 2006, 14:55:44

When I fire her up, my 2.25 diesel smokes (whitish smoke) like a [!Expletive Deleted!] for about a minute or so. Am I right in suspecting worn valve seals?
Cheers  :lol:

Condensation? Would that be coolant getting somewhere it shouldn't be? Don't like the sound of that  :?

mine does that. apparently a fuel system specialist said its was my injectors not atomising the diesel properly so the when the engine is cold, it doesnt burn the diesel fully.
once its warm, its fine.

Then again its a 2.25... mine does the same, but only for about 5 seconds after firing..

Same here, but as said it clears almost straight away.  I just live with it, don't see it as a big deal.  It'd be nice to have a clean exhaust from starting, but remember not many diesels do, so a bit from a 30+ year old engine isn't a worry point for me.

i would look at the fuel system first aswell, shoulnd cost you much to have your injectors re nozzled. it would make your motor run better aswell.

Mine does but its a cocktail of a few things. Valve stem seals are not a tight fit anymore so whilst the engine is hot and turned off the oil leaks down the valve guide and sits on the closed valves ready for the morning and the valves that are open it just lands on the top of the piston. You got to remember it only takes a drip of oil on top of one piston to do the smoke thing.

Also the injectors can also cause this problem. When you switch off the engine and the injectors are still under pressure the diesel can drip out over night and leave the tops of the pistons wet which also causes smoke.

Do you do greenlaning ? If so when you have left the engine ticking over for a while do you see smoke coming from the exhaust... ?

Do you have a leak of oil from the top of the rocker cover where the breather cap is ?

I don't know if he does, but I do.  Do you have a diagnosis and resolution to this problem?

sounds to me like worn piston rings, which means you get pressure building in the crank case and so it pushes oil out of the only available outlet

Yep he is right. That would be worn oil control and piston rings. What it is is the compression is leaking past the piston and blowing the oil out of the top.... Thats if it is doing that....
