I had the front intercooler radiator on the 340 get punctured near the bottom, there was no guard or anything.

I've been trying since Thursday night to get the exhaust and rear bumper installed correctly. I'm about to drive this f****** thing into the river. I think I got it though. They really make you work for it. All the trim and stuff has just taken forever to install correctly. I also had an 18 mm wrench fall off the guiding link bolt and smack me right in the mouth. I spent most of yesterday bleeding significantly. Today I look like s***. But we're getting there. Radiator intact... I can't complain. Sorry man.

I also forgot to add the lower radiator hose and serpentine belt to that list...

This was a 6"×6" piece of OSB that I got kicked up by 120kph traffic because just before I hit it, it was flipping from flat to edge to flat and the hit sounded solid like metal. At that moment I was so happy my front clip sounded intact and thought that it hit the stiffening plate. NOPE it made the gap

two of my most prize possessions are 21 and 28 inch titanium crowbars. they were all made Russia, probably 20 years ago or more. you used to be able to buy them on eBay, but they are nonexistent for sale in the entire world now as far as I know.

they are better at most things in every way compared to steel but they are a lot more flexible so you can get yourself in trouble by storing energy as a spring.

One day, I was in the wrong place when one of these unsprung and poked the two ends of the claw right into the bridge off my nose.

so I definitely feel you with that 18 mm wrench smashing your mouth been there, brother

Ouch! Safety glasses and gloves. Two things I've learned to wear due to similar incidents.

[andrewwynn]

I always have glasses on that have PC lenses. May have saved me big-time in that incident.

Note the bruise under my left eye where the frame hit me.

Heyyyy. Replaced the rear brake shield with all new e-brake hardware/shoes ( much needed with the 5 speed)
Next is to delete the CDV for the clutch line …

Haha.. I had very similar markings, just 2" further down.

First test drive was a success. The exhaust sounds great it's really quiet. It's pretty much stock just sounds a little different. The suspension is a little stiff so far. But the brakes are all working.

I didn't get very far though. Second test drive after topping off the diff and again bleeding the brakes, this happened:



I had taken the water pump pulley off many months ago just to look at some blue area to see if it was leaking. I took the belt off. I put the belt on correctly made sure it was on good. But I just ran the water pump pulley on with a quarter inch ratchet. Maybe that was enough deflection at 6,000 RPM.

The oil filter is full of strange little black shreds and black crumbs. Someone posted a picture of what they got in the pickup and it looks like what I have in the filter. There was also some copper flakes in the filter. I attempted to borecope through the oil pan and dipstick and couldn't really see anything conclusive. There's not really a crank pulley tool available. I'm fairly certain it's in there. A new belt is 90 g I have about 60 g accounted for. So this thing's probably coming out. Salty b if you're reading this I probably won't be seeing you at the junkyard this month. I don't know what I'm going to do yet. If anyone has a half decent m54b30 long block sitting around let me know. Maybe I can just clean it out and do the rod bearings.

Ugh. Did it get sucked into the crank seal?

I'm not aware of m54 having an issue with swallow serpentine through FMS but I've experienced it happen with the N55.

If you can examine the rod bearings with the engine in place, and especially if you never heard knock, there's a good chance you didn't cause crank damage.

I just did the initial autopsy on wife's n55 that spun 2-3 rod bearings and it looks like the crank survived. Likely needs to be polished and 50% honed just a bit but that can use thicker bearing shells and be restored.

One bearing was worn down to polished copper, but the crazy one: the bearing shells turned enough to overlap and stuck to the crank and spun inside the big end until about 1.3mm wore off the outside of the bearing shells!

The rubber bits kill the engine when they get into the oil galleys and stop the flow. Odds seem good you can clean and change rod bearings.

Where are you located?

Any benefit to replacing the plastic WP pulley with a metal one? FCP has one, but some of the reviews imply that the extra weight vs the plastic one causes premature WP wear.

FCP also has a beefier WP that I've considered. https://www.fcpeuro.com/products/bmw...wart-888010330

The prior owner installed a no-name Chinesium WP which failed catastrophically halfway through a 350-mile road trip, stranding me for several days in a small town over the July 4 holiday. The serp belt was destroyed too but fortunately did not get wedged into the crank seal.

That issue on N55 seems related to a leaky oil filter housing gasket at least based on the F30 forum I'm also on. I check mine every few months.
