I'm very puzzled at what's going on with my 102, here's my setup. It's in a Giles 202, 26x10 Mezjlik, Pennzoil air cooled 40-1. I've had this engine in this very airplane for almost 5 years, and it never missed a beat. In the springtime of this year it siezed up and wiped out the left cylinder, piston, and rings, the piston was bone dry, while the right side piston was well lubed. I sent it to Keith at BME and he replaced the jug, piston and rings, and the rings on the other piston also. This morning I started her up and she seemed to run fine, about two minutes into the first conservative flight, she seized up again. Once again the left jug, piston and rings destroyed and once again bone dry, while the right side was well lubed. After landing, I immediately hit the left jug with my heat gun and could only read 189 degrees on the left side, and about 154 on the right jug. Could there be a reason why the left jug isn't getting proper lube? There is plenty of exiting in the cowl and not baffled because if OK for 5 years it should be OK, I would think. BTW the repair cost me 297.00 and now who knows what will be.
