Weep hole leak

Well at 148k on the clock the weep hole leak finally got to me. But with a BMW tech doing work on side and aga coolant pipe getting it done this weekend. Last weekend it was struts control arms and alternator bracket. I would say at 148 those failures could have been a lot sooner.

I'd say you're doing pretty good.. my alt bracket was leaking at 68,000 miles. At 148k, the repairs are justified.

825 for labor 145 of that is for parts like valley pan intake gaskets. I had to buy pipe from aga for 600. He gets the other parts at discount.

I just noticed some "green" stuff next to the "y" pipe passenger side, not sure where it's coming from and I fear the worst

Either the vent coolant Y-hose(not to be confused with the secondary air y-pipe) that runs between the cylinder heads to the expansion tank, or the valley pan. The coolant weep hole is on the front timing cover, next to the water pump.

If its not your valley pan or weep hole I would get them done anyway. Since last winter I chased coolant leaks first it was hose from reservoir to cylinder heads then expansion tank then finally weep hole pipe. I should if went straight to the pipe and save time and money.

It is possible that the leak could be from the vent coolant hose cause i don't see anything from the weep hole.

Is there a way to check the vent hose visually?

Its underneath the front of the intake manifold. If you are having a hard time seeing it, remove the throttle air duct, and then the throttle(4 10mm bolts and a connector). With the throttle removed you can easily see and replace the coolant vent y-hose. You can also see the valley pan for inspection.

Thanks Meangreen94z, it worked like a charm just like you mentioned. Was easy to replace, the "Y" joint had gone hard and cracked and was leaking.
