Hi I've just brought a 1.6 petrol zaffy a 54 plate. And it smokes like crazy ( white smoke ) but after a while it will clear to almost gone. the oil level is ok it does smell a little of fuel the water is good. And the plugs are sooty and number 1 is wet and the piston top is wet and shiny.
I've got a new MAF Sensor, new MAP Sensor and new Plugs. I've cleared the misfire codes. Is there anything else I can do before putting the new Plugs in and f*kin them up.
Please help need the family car on the road before the new edition arrives

Get a compression test done. Sounds like perhaps it's not firing on number 1 cylinder. Un burnt fuel hence the wet piston (how can you see this?). Could be valves or head gasket. If compressions are not equal the engine will need a strip down to investigate.

I put a set of old plugs from my polo and it ran perfect on all 4 cylinders no miss but still smoked bad. I took the plugs out and n°1 was wet again. I can see that the piston is wet buy shining light down plug hole 1 and it's easy to see it's wet, over fuelling. I've got new parts but don't wanna ruin them in the first run.

You got an inline HT tester to stick on no.1? Or can you confirm there's a spark on that pot? Unburnt fuel on that cylinder will do it no good; washes the oil off the

White smoke is probably coolant burning. I know you say it's not using coolant but how many miles have you done to come to this conclusion? Possibly the head gasket leaking which will cause a miss fire and the smoke you describe but knowing the z16xe engine very well and having sooty plugs I wouldnt be surprised if the stem seals and/or rings are sticking. It's mega common on this engine. It's also known to cause miss fires as the plugs foul up.

Going to get a compression test on Tuesday. Which fuse is it to switch off the fuel pump or ignition to stop the engine from firing up on the test.
Thanks
