DrLeadFoot Posted November 10, 2015 Author Report Share Posted November 10, 2015 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.

DrLeadFoot Posted November 11, 2015 Author Report Share Posted November 11, 2015 Doing the rod bearings and other odds and ends while the motor is on the engine stand.This is one of the better ones. The rod side bearings were in need of replacing. Glad I'm doing this now.Zipties to keep the rods from banging into the journals.The chaos Quote Link to comment Share on other sites More sharing options...
wasnt m3 Posted November 11, 2015 Report Share Posted November 11, 2015 Did you ever figure out why the compression was so low? Quote Link to comment Share on other sites More sharing options...
DrLeadFoot Posted November 12, 2015 Author Report Share Posted November 12, 2015 Did you ever figure out why the compression was so low? I didn't yet but a lot of signs are pointing to rings. Oil in the intake manifold. When the motor was running and you take the oil cap off it was smoking pretty badly. I have the parts for the bearings and the directions from a BMW tech for the torquing process. It is a process to say the least. Quote Link to comment Share on other sites More sharing options...
DrLeadFoot Posted December 8, 2015 Author Report Share Posted December 8, 2015 I turned the crank about 33 degrees to get the next two rod bearings into the wrenching accessibility stage. That is all. Sent from my SM-G900V using Tapatalk Quote Link to comment Share on other sites More sharing options...
DrLeadFoot Posted December 11, 2015 Author Report Share Posted December 11, 2015 Finished the rod bearings on the new to me M3 motor. New oil pan gasket and a freshly cleaned pan to match.Dirty bolts. The valve cover and oil pan gaskets were in desperate need of replacement.All clean!Need to swap over some sensors, pop in new spark plugs, install a new rear main seal and do the valve cover gasket. Then just need to pop the flywheel and clutch on and throw it in the car. Quote Link to comment Share on other sites More sharing options...
GunMetalGrey Posted December 11, 2015 Report Share Posted December 11, 2015 Did you ever think about having the crank micro polished after seeing a higher bearing wear than normal? I see a bit of wear on my m52's bearings, which appears to be due to extended duration between oil changes, and was to look into micro polishing the crank to make sure it is smooth.

The crank journals looked like glass and there were no imperfections. Gonna run it as is. The S52 crank will probably need some work.

DrLeadFoot Posted December 11, 2015 Author Report Share Posted December 11, 2015 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.

Sent from my SM-G900V using Tapatalk Back 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.

DrLeadFoot Posted December 16, 2015 Author Report Share Posted December 16, 2015 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. Quote Link to comment Share on other sites More sharing options...
DrLeadFoot Posted December 17, 2015 Author Report Share Posted December 17, 2015 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. Quote Link to comment Share on other sites More sharing options...

jc43089 Posted December 17, 2015 Report Share Posted December 17, 2015 If it rotates too easily that isn't good either. I removed one that freely spun back and forth, it should feel like its rotating through heavy oil. Best description I could think of this early.

DrLeadFoot Posted December 29, 2015 Author Report Share Posted December 29, 2015 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.
