Just measured my valve stems and the "side to side " movement of the valve at 10 mm open ( using a dial gauge ) I then recalculated the Measurement to STEM / GUIDE clearences
I got the below tolerances measured in 1/100 mm and they all looks to be more than double of the max allowed 4,5 1/100 mm
Will this be the reason of my engine burning oil and covering my surroundings in blue smoke during acceleration?
When I send it out for reconditioning should I then go for the smallest possible tolerance between the guide and stem ?
