More progress! I like this. I had no idea your car was originally an auto. Intradusting!

Time for my daily micro update with almost negligible progress!

I received some more gaskets and seals in the mail. I cleaned up the crustaceans inside and outside of the water flange on the rear of the head, replaced the gasket, I dont care that it has a small bead of embedded silicone, im adding my small slather of gray RTV anyways.

I started working on the rear main seal

We have a nice little groove here. I will install the new seal with maybe 1-1.5mm protrusion so it rides on a clean surface and doesnt hang up on the groove when being installed.

Should work like a charm. If I ever need to mess with it again I will do a speedi-sleeve

THE DAMN LAST 1/4" OF PEDAL TRAVEL

My car was also manual swapped at some point in it's life.

I cannot stress how often I pull the pedal up with the top of my foot.

Drives my OCD insane

And I thought I was the only one [emoji16]

Tonight I installed the rear main seal into its carrier, protruding 1.5mm. I will wait until I install the E34 oil pan to install the carrier/seal onto the block.

Out of my own curiosity, I wanted to overlay all the BMW 2.5L engines: M20B25, M50NV, M50TU, M52B25, M54B25, N52B25 and see how the torque curve flattened over time with all the technology advancements. Instead I lost interest and threw the modded M52 data over some data for

a stock M20B25 vs. an M52B28, M50 manifold, S52 cams, intake, exhaust, stock ex. manifolds, and tune.

I remember having fun with my stock M20 so it appears there is a little more fun in store with the M52. Next week will for sure see some significant progress as I will have some extra time, but I will keep nibbling away at things this week like I have been doing.

When the vanos hits!! In all seriousness though it is interesting that the the hp and torque curves have a similar profile between the two engines.

I noticed that as well. The M50 manifold and S52 cams sacrifice the low end, but definitely make up for it in the higher revs

Hello turd.

Last night I replaced the clutch hardline that had rounded hardware, scrubbed the engine bay, and cut off the intercooler mounts I had welded on.

Tonight: more scrubbing and paint touchup in the engine bay. Nothing worth taking pictures of, but all necessary tasks to make me feel some level of satisfaction with my efforts.

"You'll never get the crank bolt without the locking pin or at least the engine in the car"

"Nobody ever gets the jesus bolt loose at home, its red-loctited from the factory"

"Harbor freight tools are garbage"

"Electric impact guns are inferior to a traditional air impact"

Rubbish.

This is the 4th BMW crank bolt I have removed with this 6 year old HF electric impact gun.

And that same impact got my rear axle nuts loose on my trailing arms after they were already off the car. *thumbs up*

Why not just get an OBD1 timing cover and avoid the JB welding massacre that will be installing the coolant pipe.

Unless that won't work

B C

Im only removing them to check the chain guides, replace the seals, and clean them up. The covers should be milled with the head/block to keep from being too high/low so i will keep these since they match the engine

Re-RTV that shiz

Black rtv on anything that touches oil, gray rtv on anything that touches coolant, copper rtv on anything that touches exhaust. Always and forever

JB weld on everything remaining?

Things a significant other said today:

"Why do you have to clean everything???"

The slow progress, the cleaning, the painting , the toaster quality photos, and all the pointless updates continue...

If anybody in my area has experience with 24V cam removal/install/timing I invite you to join me on a magical cam replacement adventure this weekend.

This is your invitation.

You have no date posted for said event...

Or time...

Not that I don't have things that I can do, but I'm kind of playing the waiting-on-parts game at the moment.

Also, I actually don't have any experience with 24v things, but I'll be happy to tell you what you've done wrong after something breaks.

I can vouch for his qualifications in this area.
