Non-BMW Stuff on a BMW Forum

What would be the best way to see if it's reaching the gear all the way?
lil grease or nondrying paint on the gears to measure the lash?

That M20 swap in that volvo looks mighty clean.

Drove it to work with no issue! With the trunk hole patched and the HD rubber bushings in place of the solid bushings it was a very enjoyable drive. Once I got to work the flywheel chatter with the lightweight flywheel is definitely noticeable when your outside the car. Goes away when the clutch pedal is pressed.

the car looks amazing, i'm jealous you've got it on the road!

Thank you! It's on the road, but I didn't really do that much to it compared to most projects here.

if you don't drive this in cold weather much, you can opt to thicken the gear oil a bit to reduce the sound.

Looks fantastic!! Are you planning to bring it to the E30 picnic in June?
Thank you! And I forgot that was happening. I think I'm going to try to bring it.
great job dude!
The gear rattle is somewhat of a fact of life.
Thanks!

Today is probably as cool of weather I'll be driving it in. Definitely will not be driven during winters. That is a very interesting read, thank you for sharing that.

I have a UUC flywheel which is very light at 8.5 lbs and I use the mix of Redline fluids that they recommend. There is still a little rattle but not much. It is good advice.
That's good to hear. I will definitely try that.
Car is back home. Drive home was just as magnificent. Car is so much smoother without the should mounts. I cam actually hear the exhaust and m20 now. I couldn't hear anything but vibrations with the solid mounts.
And with the combination of the chip, lightweight flywheel, and new tires it is so enjoyable. I was smiling the whole way home.
I put on new auxiliary belts and one of them is squealing a bit. Need to try tightening it but the brackets were just about stripped.

Well, all has been going well until my drive this morning developed a pretty loud tick. As suggested I'm hoping it's just a rocker that came out of adjustment. I still have the spare block in case it's not that.
I also need to replace the driveline mounts - CSB, diff mount, and guibo. I'm getting a pretty significant knock when shifting. I can feel it coming from the back under the car.
Sooooo, back up on jackstands for a bit! Hoping the engine can stay in. I'm also considering putting the stock flywheel back in. I'm not sure I noticed a significant enough difference when driving the car to warrant the awful starting sound and gear rattle to keep the RHD flywheel in.

Clutch-type LSDs, in my experience, will always be a little noisy and clunky. Older diffs can have some excessive backlash in the gearing , but even a healthy new/rebuilt clutch type LSD is going to be a little clunky as the pin moves back and forth between the opening in the carrier halves.
Loose u-joints can sometimes cause it.
slop in the CV axles is most certainly a thing.
A bad center support bearing will most definitely clunk as well.
There is also quite a lot of backlash in the transmission too.
I was able to get my E30 drivetrain to an acceptable level of driveline clunkiness to where as long as I was driving smooth there was no noise. Pausing a fraction of a second longer than normal to let the engine slow down to match the speed of the next gear also helps.
The CSB was the last link in my search for a quiet driveline though.

For the ticking: rocker arm coming out of adjustment or perhaps a manifold leak. I have had a rocker lose adjustment before. An injector could also be extra noisy so dont rule that out.
I find that running Lucas Fuel Additive really quiets the M20 down a bit and im not sure how or why but It seems to be a product that actually helps.

The clunking has gotten worse so I don't believe it is just natural play in the system.
I will check the rockers tonight. I have a video but I cannot get it to load on here. I can definitely check to see if it has an exhaust leak, but this sounds internal to the engine.

A clunk like your describing has typically been worn U-joints in the driveshaft (for me).
Easy to check if it's in the air. -
Are those easy to replace?
Also, got a mechanics stethoscope at lunch and listened around. There was not an injector that was louder than the other, they were all the same. So I think I'll rule that out. The sound was almost non-existent in the block, so I'm going to hope a couple valves are out of adjustment.

BMW u-joints are non-servicable. In the event that there is a non-OE driveshaft in there, there may be grease fittings (probably too late even if thats the case).
For a reman driveshaft, I have had great luck with these guys and they still seem to be the cheapest around

While the valve cover is off, just check to make sure the rocker arm retainers are all seated securely. if any seem a bit loose you can remove them and bend them a bit for a better fit.
