Just put a converter in the car before Winter storage and noticed some evidence of coolant on the outside of the motor towards the rear of each head. Obviously not where it should be or has ever been before. I had some voltage and fuel pump issues that are now corrected but it backfired BAD one day while passing a car on the way home from a track day. I think the heads lifted but they appear to have resealed. Anyone else ever been this lucky? I've had 2k or more miles on the car since the incident and it's not using coolant. I'll pull the plugs in the spring and replace and inspect the old ones. I don't want to pull the heads if I don't have to as they've never been off the car yet but with 65k now, I'm sure I'll break them sooner than later. Thoughts? I also have an rpm related tick that only occurs while driving at light throttle between 2-3k rpms but that's another thread. Driving me nuts though as I can't get it to do it in park or in gear with throttle without the car moving so it's hard to stethiscope it while moving! Love this thing...
