Took the oil level right down and still smokes. Have ordered a new piston kit and valve guide seals. Maybe I should get the guides checked too - is there a way I can tell? I only have a simple digital vernier caliper. Have seen people using dial guages but how do you mount one on an aluminium head? Not even sure how much play is alowable. Wondering if I should just take the head to a specialist and have them fit new guides and maybe valves.
