TIP:

hey here is a tip for anyone who has a lot of trouble with installing back on the alternator cause it's so tight, when you first take it out using a prybar, watch out the for expansion tank coolant lines, and then spray PB blaster on the bottom end nut. when time to reinstall it. thread the bolt into the nut (while off the car) and hit it a few times with a hammer until you have easy putting it back in. it should really help a lot. and dont forget to tighten it really well so that the nut can slide back into place.

I don't suppose this leak would cause the same symptoms as a VCG leak? Got that smoking smell from time to time and seems to be coming from the back of the block.

If you smell smoke then it's almost always the valve cover gasket (VCG), not the oil filter housing gasket.

what is the CCV

I just did this DIY (good job beberle!) this past weekend before changing oil. After one day, I'm getting oil leaking out from the bottom of the oil filter housing. Perhaps some of the six filter housing bolts weren't torqued enough? I'm pretty sure it's not the gasket as it's new and I double-checked that it was in place (with two sets of eyes) before replacing the housing. Any ideas?

Did you clean the engine block surface? Mine had pieces of the old gasket on it when I removed it. You have to carefully remove any contaminates. Don't use screwdrivers because it will scratch the aluminum surface. Don't overtorque the bolts either... steel bolts going into alumimum block is a torque wrench MUST. Only thing I can think of other than the gasket moved while you were reinstalling... either way, you have to go back in '

Luck!

I,ve had this oil leak for awhile now, just cleaned the block and will double check after driving tomorrow, but I'm sure this is the source since the oil was accumulating right behind the filter housing where SSM1991 pic shows. Originally I thought it was coming from the CVV but that area is clean and dry. It looks like next weekend's project. And no Rocklee, you don't have to drain the oil to replace this gasket.

beberle,

Yes, the engine block surface was cleaned. The old gasket, which was very hard, came out in one piece. There were no solid contaminates left over. I can't imagine the new gasket having moved too much, as we carefully made sure it stayed in place going in. I suppose it was residual oil from the engine side. I haven't seen oil on the floor for a couple of days and the dipstick oil level is only about a millimeter down from the subsequent oil change, so hopefully that was it. Also, the bolts were torqued at the 22 N-m spec that you provided. I couldn't find this spec in Bentley's, so I was just wondering where you got it from.

I'm not gonna stress out about this now, though. I'm now having misfire/idling problems.

Thanks,

Pat

As you may have found out by now a lot of idle/misfires are caused by a hole in the rubber flexible boot that connects the ouput side of the MAF to the intake manifold. It is close to the headers and it just seems to tear where it is accordian shaped. Very common and only and hour to change out and costs about $25 for the part.

I recently purchased a '99 323i for my son and this car has this oil leak. It's on the list.

I've got two years of working on my '98 328i and my wife's '97 528i under my belt. What has shocked me about this new engine is how difficult it is to access anything under the intake manifold.

So, my question is: While all this crap is out of the way, will I have reasonable access to everyting under the intake? I'm considering replacing the CVV (and all associated hoses) and all the vacuum lines I can get my hands on.

Or, should I also pull the intake for complete access?

Thanks for all the excellent write-ups!

Keith

no need to pull the intake..remove the alternator, remove the oil filter housing then you will have clear access to the CVV and all vacuum hoses

Once you have the alternator and oil filter housing assembly out of the way, it opens up a lot of room and makes the CVV much easier.
