New engine observations
With the new 1600 cc inline six as the backround on my computer I have a couple of observations I'd like to throw out there.
1. With 5mm spacing between the cylinders to keep the engine width narrow. I wonder how they seal this area at the head gasket. Keep in mind that 5mm is .1969 in. or 1/5 of an inch. And the engine has 12.2:1 compression ratio, so cylinder pressures are going to be high.
2. The "composit" camshaft. If I read this right the camshaft is a tube with the lobes "compression-moulded" to the tube. BMW saved weight and this desigh may be fine but I'm not sure how comon this is and wonder how reliable it will be.
Just thought I'd throw this out there. It may have little merit, but it did give me reason for thought.
