Slave cylinder bolt size?

Does anyone have handy the size (dia., thread and length) of the bolt that holds the slave cylinder on to the bellhousing? I talked to a mechanic about the clutch slipping issue, and he thought perhaps I need a spacer b/t the slave and the bellhousing. So, I need longer bolts, and was hoping to pick them up on the way home before NAPA closes. Anyone? Anyone? Bueller?

I seriously doubt you need any kind of spacer between the slave cylinder and the bell housing. My 240D doesn't even have a gasket in this location.

The beauty of the hydraulic clutch system is that it is totally self-adjusting. It "settles down" to the correct positioning after use and then when you push the clutch pedal down you always get the right distance of travel on the clutch release mechanism.

If your clutch is slipping it is not likely to be the hydraulic slave cylinder refusing to back off enough to engage the clutch.

How long

is a little while? Two plus days of stop and go driving, and it doesn't seem to be getting any better...

If anything, before the hydraulic system adjusts itself, the pedal movement would not release the clutch. I don't know of a condition where it would hold the clutch in to the extent it would slip. The system errs on the side of not pushing far enough, not an error in holding the actuator in too far.

Now you could have something broken inside the clutch area that prevents the clutch from fully engaging. But I don't think there is likely to be a problem with the slave cylinder unless it is binding somehow inside the hydraulic cylinder - again not likely.
