You stand by your opinion and there is absolutely nothing wrong with that, I agree with you on a lot concerning OS, there is very little chance I'll buy a brand new OS ever again unless it's a ringed motor, I've torn down so many of there engines the last few months, so far I've seen peeling in 4 out of 10 engines.

as far as glow plugs are concerned, I've never experimented much with different brands, I'm quite ignorant when it comes to them.
