anyone here hear about this? the Porsche alum clys are coated with this,, and are very reliable.. has benifites to this. oil retension,, unwearable cly walls. etc..
Yeah, apparently they only tested them on European fuel, and the relatively high levels of sulfur in US fuel dissolved the coating. Oops.Funny thing is BMW had a bigtime problem with their Nicasil blocks in the M60 V8 engines and had to recall most of them due to chipping, wear, oil usage and general durability problems. Go figure?
