The E46 M3 Journal

Did the valve cover gasket, spark plugs, and oil filter housing gasket (this was very necessary).
Going to swap over the water pump and thermostat from the old motor. Also, will swap over the under drive pulleys.
Need to get on the headers next.

A caliper is not for measuring journals. Machinist rant over. I wish I was working in my car rather than drywalling. Sent from my 831C using Tapatalk
Forgot I had this caliper from the ammo reloading stage I had before I got my license. 
I have the 49mm bearings coming tomorrow. -Have a lot of clean up to do on the outside. Oil and corrosion from winter motoring. -Swap all the new sensors over to the new motor. -Valve cover gasket and plugs. -Move all coils over to the new motor. -Clean vacuum lines out with brake cleaner. Sent from my SM-G900V using TapatalkBack the truck up... Is that the standard size bearing? As was pointed out, a calipers is not the right tool for measuring crank journals. A micrometer would be better, but... after thinking about it, as long as you plasti-gauge it before get too gung-ho sealing things up, you should be fine.
-
I hope I will be okay. Didn't plastic gauge it. From reading a bit about the process, knowing how hard the crank is and not seeing/feeling any damage on the journals I'm feeling good about everything.
Going to try to get in my 1 car garage and play musical motors this afternoon to get the newer S54 towards the door so I can get the picker in play. Currently have 2 m52 blocks, 3 m52 heads, the front everything of the e46 M3, a bunch of m52 parts and an e30 in the garage.

Moved the motors around. Got the new one towards the garage door.
Is there supposed to be a lot of play in the flywheel assembly? Seems weird.
My 1 car garage situation...
This is the only exhaust nut that was loose. I used all new nuts and the threads were very clean when installed.

Swapped over the intake cam sensor. This one is a slight pain. Need to take off the vacuum tube and fuel rail/injectors.
Turned my attention to the TPS sensors. Took the definitely working ones from the old motor and put them on the new motor. Then swapped all the parts I took off the new motor back to the old one so it can remain complete as possible.
Ordered a couple of transmission gaskets that will get here Wednesday. Also need to swap over all the pulleys and tensioners because they were recently replaced on the original motor. Rear main seal to do still.

Slowly chipping away on getting the M3 motor back in. Rear main, gear selector, and transmission input shaft seals all done.
We all know the drill. Pop a hole.
Screw it in.
Needed a bigger screw. And slide hammer it out.
Rear main and pilot bearing all snugged up.
Old shift selector seal.
New one installed.
Transmission input seal.
Next to do is the throw out bearing and clutch fork pivot plastic thing. Pop on the flywheel/clutch/pressure plate. Then mate up the motor and trans. After that it's SMG time!!

How much of a bear is it to pull the selector shaft seal out without scratching the bore? SOP with e30 guys is usually to embed the old seal further into the trans by hammering it in with a 12mm-ish socket and then put the new one in without the risk of gouging the seal bore.
Boom, double seal

It wasn't too hard. Just took my time and didn't apply too much pressure.

Not too m3 related but got a winter wheel setup. The m3 is displayed in its current status.

Picked those up from Kerry?
I did! I'm really digging them on the 325xi

Flywheel time!
Took a scotch bright pad and lightly went over the surface.
Torqued down the new bolts to 105NM.
One car garage problems...
Picking up new exhaust manifold gaskets and nuts from BMW today. Not too much to do after I swap over the headers.
Install to-do:
- Headers
- O2 Sensors
- Swap passenger side motor mount arm
- Loosely bolt up motor mounts
- Pressure plate
- Clutch fork, pivot pin, throw-out bearing
- Bolt on Trans to torque spec
- Bolt on SMG systemBundle up and install motor. Outside. In a Wisconsin winter.

Header time!
Took off the headers and labeled both sides of the O2 sensors on both motors with different color zipties.
The old one is on the stand. New one on the ground.
What I'm dealing with for a work space.
