Mine were about 1" long. That is why I threw the (

torx bolts away and used regular hex head bolts on the CCV and throttle body plate to the manifold.

1/4" ratchet + hand to push hard into bolt don't!

Maybe my torx bits are on the longish side. I wasn't able to shove the bit into the bolt and hold it in place as I wrenched (torqued the torx?). The bit driver made a more compact fit and has a longer lever arm. My bolts were really tight, too.

Greg Site address is what you found I think

This will take you to the page, it is the M54

1/4"drive ratchet bit & torx bit will fit in there

The six has a unique problem in that the>>

oil separator is in such a position that it gets little engine heat. The V8 separator is snuggled in behind the front cover, and gets much engine heat, so sludge doesn't seem to form as readily.

I did my V8 CCV, same symptoms

Heavy oil smoke at start-up, rough idle, goes away in time. I tolerated four starts before digging into it. Maybe it was because my first start was in front of 70 bike racing friends who then filled me with comments about my POS German hotrod pimp-mobile for the next three hours of racing.

The CCV is a bugger to get off on the V8 because it is on the back of the manifold very close to the firewall. The torx bolts get tight in the plastic, and there isn't room enough for a socket drive. I used a hex drive torx bit in a 1/4" drive breaker bar. There is a silicone diaphragm that was torn. When removing the CCV use care (wiggle slowly) so the vent tube running fore to aft through the manifold is not dislodged from the fore recess it pushes into. If it comes out a mirror and flashlight may be used to get it back in place if you are a tiny gymnast. Otherwise it's easier to remove the manifold. Putting the new CCV on is easy and reconnecting the hoses is easy. Maybe two and half hours? Fortunately for me it was May and warmish. Hopefully you have a warm bright place to work in.

Would you mind posting a link to this Bavauto

blog site? I found one entry for the M54 engine. Looks similar to my M52 6... or is this the entry to which you were refering?
Thanks.

My vote CCV

Do you live in a cold climate? that's when the CCV problem will show up.BMW found out that they needed to insulate all hoses and the unit itself in cold climate areas. Just did mine on a 03 530 6 cylinder don't know how bad a job it is for the 8. No problem in the summmer as soon as it starts to freeze out, smoke at start up and sometimes when I was going down the road huge clouds for 5 seconds then nothing for a few days then back again. I bet that's your problem. It's a oil separator system and when it plugs up it sucks oil into the intake and that's what causes the smoke.If you unclip the top hose that goes to the unit I would bet you will fined like a yellow whip cream plugging the hose. When I took mine out it was everywhere in the system.
Hope this helps. It took me about 10 hours to do mine, and about $175 in parts. Now that I did it I could do it a lot faster. Bavarian Auto parts blog has a great picture article on how to do the 6 cylinder.

Re: Sounds like you CCV

Thanks Whorse. I really hope it is my CCV. For a while I was thinking about almost giving my car away since I thought the entire engine needed removing.

IF its not CCV related -might be your valve guides

You sure its oil burning?

Sounds like you CCV

Its a common problem
I haven't had this happen (yet:|) but what your describing sounds like what happens when the CCV is clogged/broken. BUT im not sure if it stops after the car is warmed up and the crud in the CCV gets softer.

Blowing smoke at startup but head gasket good...

... I think. I haven't done a compression check.

I have a 2000 540i with 154k miles. It has a slightly rough idle when the engine is cold but other than that it runs great. It isn't losing coolant and isn't losing much oil but often at start-up it blows out a huge amount of oil smoke.

There is no coolant in the oil and no oil in the coolant reservoir. This has been going on for about 4 months. I just bought a new car to replace it but I don't want to give up my 540.

Does anyone have any idea about what I can check to find out what the problem is? I know the valve cover gasket leaks but the smoke is from the exhaust pipe and not the front of the engine.

Thanks
