Hi guys new to the site and after some advice.

bought a non runner beetle been sitting for 2 years and was only firing on 3, no.3 cylinder failed compression and a leak through identified the intake valve to be faulty. During the leak through test the battery went flat and the car was push started (gave my jump leads to a friend lol) when everything was back together of course, anyway when it fired plumes of smoke came out of the exhaust, I wasn't overly fussed at the time as the engine had to be stripped.

On to the next part, head off no. 3 valve replaced as old one slightly out of shape, new valve seals, new head gasket , new bolts, new gasket set, new vw coolant, new water pump, new timing belt, new crankcase breather (old one was split) new intake pipe after maf as breather pipe split, new air filter, new oil, new oil filter. Leak through showed no leaks on any cylinder, job done so I thought, it's still chucking out smoke and a watery substance that smells like fuel, it has no oily residue, I'm not loosing coolant and the oil is clean, I am now stumped it hardly smokes at idle, I get more smoke on over run, it is white by the way and not steam as it lingers and under heavy load it turns black.

could this be down to old fuel, I have got a new fuel filter but haven't fitted it yet as it has old fuel in the car, should I change it and drain the tank ? I've checked injectors they are all pulsing evenly (listened through a screwdriver)

the car idles lovely but bogs a little when accelerating.

any ideas would be gratefully received, thanks for taking the time to read this post

*edit* forgot to add eml shows p0407 egr, I've removed and cleaned but still faulty
