Andrew,
Tony may be correct if it is a small leak of coolant and is getting sucked
into the cylinder on deceleration along the same principle as the valve
guides. I guess the issue is what smoke are you really seeing - white which
indicates water or light grayish blue which indicates oil. When you see
water vapor you'll know it - it's really white. And yes, at some point you
will be running low on coolant if it were a head gasket. Have someone
stamd on the side of the road as you go during deceleration and smell it. A
good sniff of the stuff will definitely tell you what it is.
I let the guides on my original motor get so bad that on deceleration at
high speed there would be a trail of smoke billowing out of my exhaust to
the point where it was hard to see cars behind me. I probably deserved a
ticket!
