Swanny!

Been a while since I’ve been on here. Moved to S. Fl, don’t have any e30s with me and decided that’s just not OK. Worked out a deal with my brother to help move all my cars parts and projects to his gf’s giant unused barn/work shop. The pic above is from yet another project I picked up. Story regarding the move coming soon...

Need manual m20 I driveshaft and exhaust for another project. Any kicking around?

[Swanny]

Over the last few nights got it in and running. Took it for a test run last night and romped on it for 20 minutes to seat everything in.

Things I still need to before the Brodeo:
Valve adjustment
Burp cooling system
Test drivers low beam
Change oil
Check oil level sender
Clean up the half bottle of transmission fluid that dumped all over the center console and ran between the seats(damn it).

[Swanny]

Everything checked out on the crank, rods, and pistons. Looks like it was a combination of rings failing and valve seats being out of spec.
The guy called me yesterday and read me the valve seat installation procedure: head at ~+170 and the seat at ~-270. He couldnt stop laughing about that.
Anywho, should get everything back next weekend

Some shots from this guys garage/shop. The block is from a 1916 ford. Brought over the entire m20 machining specs so he can measure and see where we can tweak things.

Best options and source for bearings rings or a whole kit?

Swanny!

One working car at a time. It's apparently a curse, especially with e30s.

He may have an M62 in his driveway too.

M62tu is torn down for my convertible!

[delamaize]

M60 swap. do it.
hahaha

[Swanny]

I mean i do have this blown m54 sitting in my driveway....just not several thousand to swap

[agent]

24v swap ;D

Got another compression tester from my friend and numbers ran consistent across the cyls even when wet. Assumption now are bad rings. Tore into everything this week after work and gasket was fine. Pistons were VERY caked furthering the ring failure theory.

Got the number of a local machinist to talk to about what he has the capabilities of doing. Thinking bore over and +1 rings but this would be my first complete engine built (this motor had only been a head refresh)

Any pointers/suggestions/told you so?

Grabbed the HF compression tester and then realized I should have used some thread locker on the adapter as it was left in #6. So to start @ 6 cold and dry I had 110 psi. I know this thing can read VERY low so once I fish out the adapter I'm hoping to see something similar across the board. Still can't put together why it seems to be binding up without any kind of knock or other unusual sound. Only other thought is something is caught in the flywheel so will be popping the inspection plate off to check. I just really don't want this motor to just have up and blown within 2k miles of being in use.

Fuel is right on point, went through and looked for a loose connection or something unplugged. Testing compression and leak down next but with the sudden increase in the amount of smoke coming out of the exhaust I'm not too hopeful.

Well after some fun down at the brodeo and a few weeks of cruising around home the damn engine is causing some issues. Driving home from work it died taking off from a traffic light. Pulled over on the side of the road and noticed smoke when cranking and wouldn't idle unless throttle held open. Feels like something is causing high internal friction :( guess it's time to tear down and start over

Have you tested for any fueling/metering issues? Internals seems like the last place to look for something like that.
