someone's parked a toyota in the way!

A bit of both i think, its harder to maintain a good oil film between the bearing and crank with higher pressure due to smaller surface area, which in turn leads to higher temps and contact between the surfaces. I think over all BMW did a pretty good job with the lubrication system on this motor, but there are always compromises when you are designing an engine to sell to the public. Also this engine was designed using their experience with their F1 V10, and none of them were expected to do 160,000 km !!

507

From what I understand the main issue is the size of the bearings, they have a very small surface area when compared to bearings from more run of the mill engines, and given that the red line is 8250 rpm they cop a bit of punishment. I have seen pictures of worse bearings from much lower mileage cars, so mine has probably been treated better than some, one careful lady owner, only driven to church on Sunday etc!

I belive the copper Is the first coating layer on the base metal, then lead, then a teflon type material, so almost through 3 layers In places.

About 160k.

the only thing that would make that photo better is if i had taken it, in my garage!

So, apparently got to this just in time, very light scoring on the crank but not enough to worry about, lower oil pump chain guide broken but still in place, bearings well used...

Specific requirements list; 1) Not a Granvia. 2)

Car is on a hoist with all the paraphenalia removed to allow the sump to fall off, found a leaking power steering hose so that is on its way from Germany, power pulley arrived yesterday so will be fitted at the same time, should help with the running in donuts! Also noticed some tired bushes in front suspension but will get those replaced at next service after bearings are run in.

yep, good ole slush box, better for smooth takeoffs and apparently that's what M5 owners are all about these days! Lets face it though, that auto will be orders of magnitude better than the old 4 speed in your dads Cortina.

Are you sure? my e36 had an issue after i changed the door handle, the new one was from an ews car, and if i didn't unlock the door with the key it would crank over until the battery died but wouldn't fire, if i unlocked the drivers door with the key or reached into the door and flicked a little switch on the handle housing it fired up straight away.

Because there's ALWAYS one !

Check the bottom of her handbag (if you dare)

Im pretty sure you mean E61 M5!
