E21 project thread

I did a compression test today and compression on all cylinders checked out fine. Looks like all is good. My spark plug gap was really high tho, so I regapped them lower and seems to idle a lot smoother as well.

This car drove.
For a whole 30 feet!

From last 30 foot drive, I heard a grinding/thumping from the rear which made me stop. This morning I raised the rear and noticed the driveshaft was rubbing on the exhaust. I got 2 new rubber muffler hangers and that fixed the issue. I then noticed a small oil leak. During my investigating I have a hunch it is coming from the thermostat on the oil filter housing. Hard to tell tho from the clean oil and whatnot.
I just drove it around the block for the first time and it was interesting. Lol. Figuring out Megasquirt as I go is probably going to take some time.
I also think there might be an exhaust leak at the turbo. Nows the time to get all the kinks out I guess.

I had a steady drip from the oil cooler thermostat on my m20, it got to the point of a drip every couple seconds when the engine was running. I replaced the o ring (which comes with a new retaining ring and metal cap??) and all was well. The old o ring crumbled into pieces when I removed it.
-
Not sure if mine has/had an oring since its basically just a sandwich plate with a built in thermostat. I know it has a c-clip that holds it all inside the housing tho.

In due time sir, in due time.

I don't have an m20 in my e21. I am using a purolater thermostatic sandwich adapter on my m10 filter housing.
-
I didn't know if they used a similar setup on the m10. I didn't realize yours was aftermarket, I have considered using an adapter to do a remote mount filter on some cars with poor filter placement to make oil changes easier. Would you recommend the Purolator? I use their synthetic line of spin on filters for my non BMWs.
-
Yeah I would recommend Purolator. That is my go to filer for my car, but most the time no one has it in stock so I end up having to get something different.
I have been tuning and tuning with Brian (Snap) and we are kind of stumped. It is running almost as if a spark plug is intermittent or wire is bad, but I just replaced plugs and wires. We are aiming towards the coil not producing a hot enough spark and maybe even the EDIS module not being grounded properly due to it sitting on a painted surface. I will be replacing the coil today and possibly grinding the paint away from under the module. Hope this works.
