Weep Hole Seepage

Is this the weep hole seepage everyone was talking about a while back?




It's definitely weeping from the small hole in the top pic that's right above the gasket line. Seems like coolant or something. I wiped some off with my hand and it didn't seem oily. Seemed dry. It's whitish colored. Seems like coolant. Am I fucked? Or is this a common thing with these bikes?

Looks like they'd have to remove the cam cover to get at that seal.

Shit.

What seal is it?

my f8gs weeps oil from that hole... I haven't pulled off the water pump yet to check, i'll probably do it next week.

What I have notice is the extremely poor torque on all of the engine bolts. For example 3 bolts on the water pump were not even hand tight, when the bike heated up the pump would leak, re-torque / no leak, that's when I discovered the oil weep from the above hole. I also had oil leaks on from around the clutch cover, I loosened all bolts then tightened them up by tighten opposite sides, wow, no more leaks. Who ever assembled my motor either bmw or rotax failed on the day they did mine and the dealer "I was using" failed as well. So the golden rule want it done right do it yourself!!!

Yep. Been there done that. Seeped oil the first time and had to have the water pump replaced. Seeped coolant a while back but that was from the coolant hose that was too short and got replaced in a recall. I have noticed after a long spirited ride or some slow offroad when it's hot outside it does burp a drip or two of coolant every now and again.

Mine is getting this same problem fixed right now.
Started a few days after I left for SA.
Was only intermittent, and didn't seem to get worse over four months and 20k.

Every so often mine will drip a drop or two of coolant. No biggie I guess. It's only done it twice in 10k miles. I'll have the dealer check it out when I take it in for the 12,000 service.

Stopped by my dealer with the bike today. I'm going to have it checked out on Monday. More than likely they'll order and install a new coolant pump. There's a mechanical seal in there I guess.

Seals on both sides with a void in the center where the weep hole is. I believe. Made like this to separate the oil from the coolant. Unlike the KTM LC8 mill which when the seal goes, and it will, it dumps directly in the oil.

I must have gotten a good one because in 11k miles I have had 1 issue. Notta one.

Oh, I shouldnt have said that...............

My dealer has a new coolant pump on the way.

Again, I'm super pleased with the service at Hopkins Hitching Post!

My bike is at the dealer as we speak for 6,000 mile service. Getting new fork seals as one of them is damaged and leaking under warranty. Switching over to AMSoil 10w-40 and a Mann oil filter. However, we (the BMW tech and I) decided not to do the coolant pump replacement. It has not purged since I started this thread. The BMW tech said he shot an email into BMW and the response was, "the coolant pump will purge from time to time intermittently. This is normal. It's the way the system is designed. If pressure builds up too high within the cooling system due to heat or atmospheric pressure, it will purge a bit if needed. The BMW cars have a 'catch' reservoir for the coolant pump weep hole on their engines. This is the way they are designed. Now, if the consumer was reporting constant purging or a leak somewhere, that would be a warranty issue. The random purge is actually the system doing what it's designed to due under certain circumstances."

So there you go. It's all good.

Mine did that in the fall. The big difference is that is looked more like the valve cover leak than what you show. They started to investigate the cover, but found that it was the water pump. They happened to have one in stock and did the seal at the same time.

My tech told me that it looked like my pump was over-packed with grease from the factory, and when it was hot enough, the grease broke down and became liquidy and then was purged. He also did necessarily fell the need to replace the pump, but they had it and it was authorized! Not a drop since (and that includes a huge trip in May).
