Rody, what temp do you try to get the engine to by pre-heating before starting?

You also want to get the heat into the engine quickly! What's happening is the sleeve gets hot and expands, but the piston doesn't, and this loosens things up, and reduces stress and wear, durin break in, but i also preheat later on in the engine's life. I preheat religiously, every time, always, continuously, no matter what, forever! After break in, the only wear the piston and sleeve goes through is from cold starts, where there's no lubricating oil, and everything is super tight. Preheating makes my engines start super easy also. It does make break in take a bit longer, but it's well worth it.

I use 30% exclusively in my S7ii from the very beginning. I would recommend adding one 0.1 shim.
