1998 528i CDV removed!!!!

Reverse bleeding is always a bad bad and bad idea.

why?

Because reverse bleeding brings contaminated fluid, either from the brake caliper or slave cylinder, upstream into critical components.
If any place that gets contaminated brake fluid, it is always the brake caliper drawing in water, mud etc into the caliper, and slave cylinder for the same reasons.
Do a search on reverse bleeding and you will see it is not recommended. Actually it is discouraged.
Always bleed from above downward.

Can't remember where I saw the caution (think it was cn90), but what's the reason for -not- pressing the clutch pedal all the way down when bleeding the clutch line?

By way of cross reference, there is a healthy discussion today of how exactly to bend the line for the CDV delete over in this thread:
- E39 (1997 - 2003) > CDV mod from zeckhausen

i think i just found my next mod thanks guys!!!

By way of reference, these nice CDV delete pictures were posted just now over on the E46 side of the house:
- E46 (1999 - 2006) > Got little sucker (CDV) out

End result: much smoother engaging and feels more responsive

Edit: Just noticed it says LUK, same as old flywheel and clutch. Was that a aftermarket CDV?

For the crosslinked record, this thread today refers to the CDV delete & explains why:

As Edjack said, stay OEM.

And removing the clutch delay valve doesn't make it killer, it removes the slippage and jerkyness the CDV causes.

Thank you for this write up.
I just did my diff then the cdv now on to the trans

I wanted to say i know my cdv was never drilled or punched and it has the same size opening as yours.
