I have a "low friction" early B230 (B230K carby with heron heads, to be exact, but probably not relevant) that I'm not sure what to do with.
I bought the car it came in with "bad knock" and promptly convinced myself that it was a low-friction bearing failure. Turns out it was something steel dropped into the carby at some point and found its way into cylinder 4 where it did a fair bit of damage.
Although I've not cracked the caps just yet, the engine has 300,000km on it and I couldn't detect any play in the big ends by rotating the crank back and forward. IE, it's probably fine even with highish mileage.
So the questions are:
1) Are these engines really that bad? Or is it all/mostly internet/FAQ hype?
2) Or is it just in turbo applications that they don't hold up?
3) Any info on the friction difference in terms of torque or power with all else equal?
And the final one:
Do I keep it and put a 16v head on it and use the low friction properties to make a little better power than the later/better engines can in a naturally asphyxiated way? Or do I pull a few bits off it and send it to be turned into shipping containers and caster wheels in China? And bide my time for a third squirter block.
I'll probably pull the pistons/rods/crank out of the block the night after tomorrow and can post pics of the bearings then.
Any and all thoughts on low-friction vs later B230 engines welcome!
Chamber/piston pics for amusement:
And a couple of teasers for another thread I'm yet to start:
Again: Any and all thoughts on low-friction vs later B230 engines welcome! Cheers!
