Well, the only one thing I found in your post about that motor-red clay fell off, the rest was again about service, which is not a topic. I saw that clay fell off on MAX too. Then you sad metalurgy is poor-how do we have to understand that stament? Which part is poor?
I am not sure if you know what I was asking you, when I ask give some tech info to proove that JP is crap.
We did test a lot of parameters on banch of motors-crancase pressure, expantion rates vs tapers, back pressure to carb from crancse by 5% increaments of opening, unleaniarity of crankshaft under pressure of combustion process etc. We found nothing is wrong with a lot of motors. I wouldn't agree with some ports lay outs (everybody has their own opinion on tech data), balancing is another thing I am not agree with.
So because you can't proove that JP is crap, you didn't post any valuble info beside clay fell out, I wouldn't take your statment seriosly and I will not recomend to anybody do that.
Sorry man, but if you make claims like that you need to stay behind it, not just empty words.
