Coolant leak @ rear of motor

[Whorse]

Confirmed its the valley pan today, made a shopping list and got a price quote from blunttech.com I added the CCV, throttle body gasket and a couple of other parts that would be dumb to leave out.

Anybody see anything I'm missing?? Anything i should order OE BMW instead of aftermarket?

It's just a plastic cover that goes over the top of the valley pan to keep junk from collecting in it.
IIRC, it is also suppose to isolate some of the engine noise too. You should be able to use your old one again.

Thats what i was thinking but every write up i see on the valley pan included this in the parts list. It doesn't even look like its held down by anything.
You see anything Im missing or anything that will probably break during this work that i should get?

heads of the nuts that hold the VP down. I reused mine, no need to spend extra $$ for nothing.
Looks like you have all of the parts needed, just get some 6mm x 1.0 x 25mm bolts to replace the torx bolts on the CCV. Home Depot or Lowes should have them.

I went to 3 home depots and they didnt have the right size bolts. Im gonna hit the mom and pop hardware store monday. They always have what i need.
Thanks again Jim!

mail you some. I bought a box of 100 of them.

behind the flywheel? BC, what plate did you have to replace? I have severe leak and the fluid appears to be coming out the inspection hole in the bellhousing. I'm hoping it's the valley pan gasket as I don't want to think of what I'm up against if it's not......

[JimLev]

will drain coolant between the block and the flywheel. It will then come out the holes at the bottom of the tranny.
If it's not the valley pan or the connecting pipe between the back of the heads or the hoses back there, then it's coming from the cover on the back of the block. That requires the flywheel to be removed to gain access to fix it.
Thought all of that info was in the link above.

I was looking at, I've never seen anything like that before. I'm mostly familiar with old American v8's and Japanese 4 and 6 bangers, I'm not that familiar with BMWs. I have no idea what the function of that plate is, I'm going to guess it's part of the water jacket, instead of being cast in, it's bolted on? Everything on this car is different than what I'm used to, and a real education. Thanks for all your help.

[Whorse]

Picture of weep holes Jim was talking about. From what Ive read and experienced the valley pan is a slow inconsistent leak not severe like you mentioned.




Lots of good write ups including valley pan if you need it.
