This is an ongoing issue I've been helping a mate with (c.gerrard on here)
Just before FCS, he suddenly lost all power. We couldn't see anything wrong, but I suspected it could be a fuelling issue, there was no smoke at all, and the power deliver was very similar to a NAD (flat power curve, smooth though, just no power)
He'd been having issues with white/grey smoke when the engine was cold, but on two occasions it was idling fine, left on the drive, then it started missing and kicking out smoke. I turned it off and straight back on again, and it was fine
We started it up after changing the pump and there was massive amounts of greyish white smoke, idling rough etc. we checked everything we could, there was no pressurising of the coolant, everything seemed fine.
We decided to lift the head, and found that the valves had had a disagreement with the pistons, we're now thinking that we got the belt a tooth out when we changed the pump
So got a head from the scrapyard, put it on, crossed everything and fired it up. It was late at night, and we couldn't tell what colour, but there was smoke.
Got it running the following day, and there was a good amount of blue/grey smoke. Let it warm up, then gave it a run up and down the drive (a long drive) the smoke on idle cleared and, apart from an epic boost leak (didn't do the jubilee tight enough), all seemed well, and it seemed to be running standard(ish) power.
Carl went home from work today and started it up, the blue/grey smoke is back. I suggested removing the I/C as if the turbo seals were gone, doing that would stop the oil getting from the turbo to the cylinders (I think that's right anyway) This made no difference. He's going to post a couple of pictures in here, one with the I/C on, one without.
I'm thinking either:
Piston rings (the engine was sat unused for a long time before he bought it, could they have seized to the bores and broken when it was started?)
Valve stem seals (duff head from the scrappy?)
Or turbo seal and I'm wrong about removing the intercooler to check this.
It's on 67,000 by the way.
EDIT: He's just told me it's running clean now, he turned it off to replace the intercooler, and when he re started it, it's running clean with NO smoke what so ever. What the actual f**k? Intermittent burning of oil? Now I'm really confused!
