Just fitted a new transfer box to the car. Took it for a 5 min test drive and everything seemed fine. Took it straight back out again and the first time I properly tried to welly it, it got half way through the rev range then heard a pop/bang then lost power. Car is ticking over very slowly and spluttery with some blackish smoke coming from the exhaust (not a massive amount). Managed to limp it home, keeping it under 2000rpm the engine didnt seem to run too bad but as soon as the revs tried to pick up it was spluttering and trying to cut out.
Quickly whipped the spark plugs out when i got back and they look alright other than being well sooted up but when I took the plug out of cylinder 3 there was some smoke coming out from the cylinder. Could this be a knackered piston ring or something?
Any ideas what it could be or any easy checks i can carry out before having to look at big strip downs?
Cheers for any ideas.
