Yes but your E30/E34/my 95 M3 did not have one. And shifting is noticeably different with the CDV. I haven't blown up any transmissions so I suspect it'll survive. :-) > What is the purpose of the SS clutch hose? Supposedly improved clutch control, removes mushy pedal feel, better slave cylinder actuation, yada, yada. Probably BS but I have one so I may try it, heck it may not even fit as mine is a Goodrigde line. I'll keep the other parts in case I need to put all that crap back.

Let's see gotta get the KP race car ready for Putnam, why not sell the perfectly good E34 and pick up a POS Jetta TDI that costs almost double and right away needed a new turbo, master cylinder, brake booster, etc and a bunch of wrenching time instead of spending the time finishing the race car. Yeah I'm the only one that does this kinda stuff. ;-) Carlos. PS The M20 will be ready to be installed after today, later in the week the E30 interior will be stripped out. Date already scheduled for the cage. Hell I've got plenty of time to goof around with the E36! :-) __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!

When the intake came off it was nasty. Thick, thick layer of gunk in there. I know some of you guys have BTDT, what did you do to make it nice and clean on the inside? I assume some sort of soaking method is required here? The rest of the work went pretty well, my goal is just to clean the engine up, paint the block, replace a few things like the oil pump, timing belt/water pump, and all the other bits (read gaskets) that make sense while it's sitting on a stand and it's easy to do. Next time we should be able to finish all the cleanup/maintenance work.
