Message-ID: [EMAIL PROTECTED] It weighs less, as everyone except Ben knows. Stroking it to 2.7L removed exactly 53.788 lbs (24.499 kg). Therefore, the chevron seals are less stressed, and the incoming air is cooler. QED.

Regards, Rich -Original Message- My whole reason for getting the B27 over the B25 was the reliability of the ETA. I drive 70 miles a day (six days a week) to and from work, school, and back home. I have a year left and then I will probably upgrade to something else before grad. school. I am so amazed at how reliable this car is. Every morning I turn the key and it starts right up. It is a great improvement over my M10 E21 that I used to drive everyday (I had to rebuild it twice in six years due to oil pump issues and missing a gear with the dog leg tranny(when I was 16:))). I don't want to do anything to the the E30 that will compromise the integrity of its purpose. thanks Barry and Gary.

Message-ID: [EMAIL PROTECTED] BMW makes money from selling new cars. New cars get purchased to replace old cars. Old cars need replacing more often with revised oil change intervals of 15K miles. 15K-mile oil change intervals advertised as customer convenience. Instant accountant-approved marketing scheme.

So engine wear hour meters focus solely on block wear? Valves and seals and bearings and such are incidental to the question of when do we have to bore or hone the block? A thought: why is there a ridge at the un-oiled top of the cylinder? No rubbing, but maximum heat, pressure and presumably corrosion. Protective carbon layer?

Warm and lubricated surfaces don't touch and don't wear. Of course, all cycles are not perfect, so there is some touching and wear, but for cylinder walls, the main wear action is from corrosion. After the power stroke, the high heat and pressure cause the piston rings to scrape the oil off the walls. They are then exposed to the corrosive combustion gases. On overlap, the lightly loaded piston returns and places a coat of oil on the cylinder wall stopping the corrosion. The exposure time depends only on the operating time, not the number of revolutions. Note that cylinders wear more at the top of the stroke where exposure time is longer. Gary Derian This statement could use some clarification. I won't be obtuse and pretend that you are saying that the dusty NOS engine sitting on the shelf is rapidly wearing out, and understand that boats, airplanes, and heavy equipment have hour meters. What is not obvious is why revolutions, which translate into distance that friction surfaces are dragged (bearings, rings/cylinder walls) and number of forces applied (piston direction changes), are not the better indicator. Does oiling become so inferior at idle? Rich friction enhancing mixture? Greater engine load climbing a grade at low rpms vs. zooming down the other side? Why is time the superior gauge? Tom (background music: Flings, nothing more than flings) Engine wear is time dependent, not revolutions dependent. Using non-scientific analysis to form scientific conclusions is folly.
