It's been a good run. And she's still chugging along.
I've killed it a few times, running inferior oil (royal purple). Running it too long, too hot. Shutting off/starting under load. I scored cylinder #1, forgetting to put in the wrist pin retainer, and resurfaced by hand. Lost a little compression there, and reduced check valve pressure to fix. Broke the crank bolt, (along with two connecting rods) likely from detonation from royal purple. Also bent my crank from using no crank case to cylinder gasket(piston hitting cylinder head). And galled the crank where is fits onto the motor shaft (from operation with loose/broken crank bolt).
Pressure gauge, rear cooling fan, and crank bolt have been upgraded. All electrical connections are now soldered and shrink wrapped.
As it sits, it has a walking connecting rod. Running corena s2 p150 oil, no measurable wear on conrod journal with several fills. An expremely high compression 2nd stage, a lower than normal compression 1st stage, an epoxied crank/drive shaft snout. And she runs like butter. Has been running like this for a year and a half now. I'm surprised every time it does, haha. Still builds pressure well past 250bar.
In summary, use good oil, don't run hot (much over 55c) or for too long (15min). Don't start or stop under load. Oh, and don't delete your gaskets!
