Yeah dude, many names on many forums its hard trying to remember them all
 :grin:

I would strip the rings out cos even if you free them up the oxidized metal and carbon build up could effectivly lap/score your bores.
As Danny P says sump and head off scotchbright the bores pistons and grooves, oh and clean out oil jets while you are there.
Cost a bit but better than taking it apart twice :smiley:

ouch,  those compression numbers are a bit to low  really need to find whats causeing the inbalance in readings and why,    Two cyls reading low is often headgasket, 100 is bad  but 150 is reall a bit low as well. but at least theer not knackerd piston low  :smiley:

as darn PB said   get some heat into it that'll help things get moveing  and see if the smoke will burn off, then do another CR test to see if the numbers come up.  and go from there
all the VW's have gone bar 1.

cheers fella
been driving it about today a bit and the smoke seems to come and go when it feels like it im getting a tiny bit of black smoke out of the breather but its not smoking no were near as much as it was on tick over and fook me it pulls like a train
i have messed about with the carbs a little and that seems to have made a bit of difference in the smoke to i will run it about tom and then do a nother cp test on monday


what should the figures be m8
