Does anyone know the cylinder bore tolerance before it needs to be bored out? (2002 Protege LX 2.0L FS engine) I can't find a mention of it in the manual.
I'd like to get an idea what the shop will tell me when I take the block in for evaluation... specifically if I can get away with throwing a set of standard rings in and go... or if it's too out of tolerance and needs to be bored for oversize pistons and rings.
I measured 4 places at the bottom, mid and top of each cylinder.
Angle=position of bore gauge in cylinder (ie 0-180 =12 clock to 6 clock position)
Measurements in mm:
(Sorry about the formatting... won't let me align the columns)
angle 0-180deg 45-225deg 90-270deg 135-315deg Max Diff
Bottom1 83.01 83.03 83.05 83.01 4/100mm
Mid1 83.01 83.02 83.02 82.97 5/100mm
top1 83.04 83.01 83.02 83.04 3/100mm
Bottom2 83.01 82.98 83.04 83.01 6/100mm
Mid2 82.96 82.99 83 83.02 6/100mm
Top2 83.03 83.01 83.01 83 3/100mm
Bottom3 82.99 83.04 83.03 83.02 5/100mm
mid3 83 82.96 83.02 83.02 6/100mm
top3 83.02 83.02 83.01 83.01 1/100mm
bottom4 83 83 82.99 83 1/100mm
mid4 83 83.02 83.01 83.01 2/100m
top4 83.03 83 83.01 83 3/100mm
Is there anything else I need to measure?
