It is COMPLETELY RANDOM! what liners you have in your engine and cannot be determined until you pull the head off the engine and measure the tops.

Just curious - how you can tell from the top? Quickserve shows measuring the "land" below the o-ring.

I just ordered a new crank and out of frame kit for mine - 150mm, flat top liners, no grooves on the bottom, no liner shims. I would like to verify the block didn't have the wrong liners in it though.

Here is where they are measured (poor choice of words I suppose, I have corrected it ) ...


As far as ensuring you have the right one, the 152 liner will not fit into the block if it was cut for 150 liners. - If you try to put in a 150 liner where the block was cut for a 152 liner, it will be very loose and fairly obvious it is too small.
