Intake is off...took me about 1+45, and thats after shooting the $hit with my neighbor for 20 mins. Not something that I want to be good at, unfortunately.
Happily, the leak appears to be from the large coolant pipe at the rear manifold. It will be a PITA, but nothing compared to "door 3": the rear coolant cover. I was a bit concerned about this because the motor is so new I figured it could be anything, not just the usual suspects.
Sure enough, a mirror shows coolant dripping from under the large pipe, and the valley full to the weep-holes.
I cleaned up the valley mess and stuffed a rag under the pipe to see if I may also have a valley pan leak. That would be super unlucky, but it is a BMW and I'd rather do both jobs now than have to pull it apart again.
I noticed oil around several intake holes, and the small oil return line from the dinky plastic nipple on the breather valve was off. This was a huge pita to get attached while dropping the intake on, and clearly I didn't do a good job. I'm wondering if this would cause oil to be drawn into the intake. I'll pull the valve and look at it, and the intake. The car doesn't use very much oil at all however, so I'm a bit stumped about the oil under the intake gaskets.
I sprung for new pipes, o-rings and rear manifold gaskets. I think I'm going to pull the manifold and get the pipes out that way. I reused my old ones, and my old manifold on the new motor, and I'd like to check the manifold out. It didn't leak for close to 2 years however, so I suspect I just rolled or cracked an O-ring.
On a positive note, I took the Quaife diff down to the local steering shop and had the press the new output bearings on. Much easier than me banging on them with a hammer and a big socket. Its ready to assemble and test for backlash and gear mesh.
