E34 550iT....The Gristle Hammer

You're talking about the headstuds or main bearing cap studs?

Eyeballing headstuds as we speak....

Yes ,, ARP head studs,,,,

i think nothing is more annoying then a bolt lose its grip because of bad threads

[slammin.e28]

The main bearing were not that expensive,, as oem,, but the rod bearing ,, i paid over 1000 US$ for them here in Iceland from the dealer,, and they are ONLY MADE for BMW... damn expensive

STUDS,,,,, do it,,, absolutely,,, even the M70 is a high quality alu block, i would recommend studs,, use the M50/52 same length as oem M70 bolts

Oh yeah. I wasn't going to but the curiosity was killing me as to the bearing condition. Then I discovered this place called Calico Coatings that could recoat the shells, mains and rods, for around $130 or so. Seeing as each bearing HALF is over $20 each from BMW, it was a no brainer. Hopefully have the shells back early next week then I can start re-assembly. Also still waiting on my main cap bolts. Stretch bolts. I would have gone studs but the bolts are half the price and these bottoms are goddamn stout. Don't see the point if I use new bolts.

I can't wait. This thing is gonna be so nice.

I think I'll get a touring next, not a fan of the iX to be honest.

E34 550iT....The Gristle Hammer (3/8 update)

Heads all done up two weekends ago. Valves lapped, new guide seals.....fresh.



Block is 100% torn down, but I've started bolting bits back onto it. Waiting for my bearings to come back from coating and for main bearing bolts to come in from Germany. The tensioner guide is wild...that little gear is kinda cool. Pricey little bugger.



Pistons all cleaned, rings are all free and the lands are free of debris, etc.



I totally disassembled the oil pump and cleaned it. Good thing to, as the pressure relief was stuck shut. Got that all freed up and perfect, lubed everything and reassembled.



I have had every nut/bolt out of this engine. Every. Single. One.
....and there are a lot.

[slammin.e28]

New engine tear down.







....annnnd when the head didn't wanna come off I went about tapping it with a rubber mallet....tapped just right in the just wrong spot...dumbass.




Oh well....two more heads at home w/~90k miles or so....so no biggy.




This weekend I'll go through the heads, lap the valves, do guide seals, etc, then it'll be really close to going back together....should be one more weekend to get it assembled...then I'll bring the Hammer in and do the switcheroo...

I sold the 318Ti too, so I've got more capital to dump into the Hammer, so I'm going to get a new flywheel and clutch. May even address some other issues with the chassis. Going to swap in the rear from the 750iL. 7mm wider (at the hubs) and I can run the larger axles. Also need to do the hatch wiring. It's started to short and kill fuse 1, which controls, among other things, the cluster and brake lights.

Is that the famous "Horse Cock" hitch?

Yessir!

[MrBurgundy]

The best part about this car is the "Where's your v12, Peasant?" sticker

[slammin.e28]

I went ahead and got my euro hitch installed. Just have to get the cover for the hole in the rear bumper before I get that wrapped up.



Also did an aesthetic thing:




Gearing up to pull the engine from the other 750 to put into this thing. Going to tow the Jensen home from Vintage this year.

wow, this touring is wicked.

[elcoy]

I'll have you know I am going to look at a cheap 750il today just because of this thread...

I might shelf the dream of a S38 touring if I can pick it up cheap.
