Well, first off its running again, and quite strong for a 2.4. ANyways, Im not out of the clear yet, totally opposite actually. After the 3L head swap, on startups this thing has super rough idle and smokes white/blue to the point where I am embrassed and afraid of getting a ticket from the enviro police! Seriously!! Yuo may remember when it overheated it was roasted well - cooking hot. When we had the head off bores, and piston tops *looked* OK.
I did check the glowplugs and they are getting juice. I will pull them this weekend and do continuity test.
I am appealling to the collective knowledge on this board.
Why the crazy smoke? Others have done this swap with same results, same motor, some in England, some in Aus etc. with no or very few solid answers. Rough idle for a minute/30 sec and lots of whiteish smoke. ?
I was talking to a buddy and he suggested the turbo seals might have got fried if there was low coolant being near the top of the motor and tings got very hot. This makes sense. BUT when I get up to temp - it runs like a dream. Lots of power, little smoke (maybe a bit o black on hard accel), great fuel consump, smooth etc. Wouldnt I be spewing huge coulds of smoke when hot if turbo seals were gone? This stratup routine HAS to change.
I will pull the turbo inlet off ASAP to check for (hopefully) gobs of oil!! At least it would be a known straight forward fix (albeit $$). But I would much rather have that than mystery...
What other things could I check?
What does a leaky injector do on start up? Could this be? HOw to check individually can I do this without full removal?
Injector pump/EFI module? No ideas here....just throwing it out (well not really yet ) Althoug Im thinking I could use a manual pump and ditch the elecs.
HOw about air in fuel lines somehow overnight?
Any chance the machine shop buggered up valve re-grind or valve stems?
Lastly, dreaded head off again to check for water, but I dont think this is so becasue Im not using/loosing coolant anymore!! Hooray! And the colour of smoke is blue/white and not steam.
Even going shopping for 2 hrs in -2C it puffed quite a bit more than it should for sure. The truck ran well with no smoke and pretty smooth cold startup idle before the head fiasco.
Well, a bit of a rant sorry. Guess I should go and do some more diggin around before I whine away on the board.
cheers,
Johnny
