Mike's Alpine White 1991 318is

This should be on a nice set of coilovers. It totally deserves it.

It was good to see you this morning, Mike. Car looked great, as always!

It has been about a month, here are some updates.

Transmission Mounts

I replaced these a few weeks ago. The old ones were in decent shape, but the new ones were $7 each and it's a very easy install so why not. I haven't noticed much of a difference to be honest. There was a noticeable difference when I replaced the engine mounts about a month ago.



Intermittent Ticking (Lifters) Issue Resolved?

At the risk of jinxing myself, I believe I can close the book on my ticking lifters.

Over the past couple months the loud ticking became more and more common. It never affected drivability or performance. I posted about it here.

I dropped the oil pan to verify everything looked good, which it did:



I removed the valve cover to inspect everything, which also looked good:



I replaced the timing chain tensioner, which had no effect.

I checked the spark plugs, wires, and coils. No effect.

I added Liqui Moly Lifter Additive, which quieted them down somewhat for half a day, then it came back louder.

I changed the oil from Mobil 1 15W50, to a thinner Rotella T6 5W40. The seemed to have no effect as well.

Eventually I became fed up of not being able to properly diagnose this and I wasn't 100% sure it was lifter noise. For all I knew it was a crazy loud injector or an odd exhaust leak. I made an appointment at RRT to have them figure out the issue.

I took the car to RRT earlier in the week and gave them the list of what I've done, photos, videos, and other information. After looking at the car they called me back to the garage. The car was totally silent. No ticking. It's like my kids: angels at school, but not always the best behaved at home.

So Alex, JW, and I chatted for a bit and they sent me on my way. That was 5 days and 300 miles ago. The car has not ticked since then. The car went from ticking on a regular basis to not ticking at all. I have some theories:
- RRT fixed something in ~15 minutes that was glaringly obvious and didn't want to tell me because I'd feel like a moron.
- The thinner Rotella T6 5W40 cleaned out the oil passages and removed varnish from an offending lifter. It just took a few hundred miles to do it's work.
- The Lifter Additive, which was only run for 500 miles with the Mobil 1 15W50, may have continued to work it's way through the system after draining the M1 and filling the T6.

As of right now the engine sounds like the regular old M42 sewing machine and that makes me happy.

Mileage turnover
I always miss these, but I was stopped at a light, looked down, and saw it about to roll over 144K miles. Yes, I synched the trip meter with the odometer when I got the car. :)



Track Days (bro)
I'm signed up for a 2 day HPDE with BMW CCA NCC in September. Looking forward to that! This group requires a shop to perform a tech inspection. I'll be taking the car back to RRT next month for that and an alignment.

Cars and Coffee
I've been busy, but I've managed to make it out to a couple C&C events and catch up with friends.





Steering Wheel Search
I may have eaten my steering wheel budget with the track day registration costs, but I'm on the lookout for a good condition Nardi Blackline steering wheel. Please let me know if you come across one!

Ok, so I've confirmed mine doesn't move more than 1/4". Here's how I measured it:

I placed some tape on the wiring harness cover (static point). I marked a line on the tape which lined up with the 90 degree elbow for the ICV attached to the engine. I then (not pictured) taped a straight, thick coat hanger wire to the top of the intake manifold so the end would line up with the mark on the tape. I rocked the engine back and forth and never saw the wire move more than 1/4" past the mark. Not perfect measurement, but a quick and easy way to gauge how much the engine moves relative to a static point.

Absolutely perfect, that's 100% what I needed. You're a total gentleman.

Beautiful car ! Perfect ride height too !

I dunno about that, I think it could be lowered with some coilovers.

[mike.bmw]

Since you've got new mounts in, can you give the engine a wobble and tell me approx how far it moves side to side? If I push on the intake manifold from left to right there's a good 15mm movement (3/4in?) and I'm not sure if that's normal. Mounts were fitted to my old car for a few thousand km, stored for 3 years, then fitted to the new car. Want to know if they've had it or not

I got out of the house early this morning for some photos (5:30AM). Unfortunately I left the camera battery on the charger at home, so I didn't get back to the spot until 6:15AM. The light was still decent so it worked out.

The location is under a bridge alongside the Washington and Old Dominion Trail in Virginia. I've biked and run this trail many (many is an understatement) times over the years. Only recently did I see some cars parked here for overflow parking and thought it might be a cool place to take some photos.

Really great stuff.

Your car is the benchmark for my recently acquired 318is.

Wonderful.

Glad to see you are still making your car better. It brings me joy to visit every year or so and see progress.

Love everything about this car. Good work!

Thanks, guys!

I will try to take some measurements later today, but I don't think it moves much. Definitely not 3/4". My old mounts were pretty shot as I can compress them with my hand and it appears the liquid inside was making it's way out. The car drives MUCH better with the new mounts. Shifting feels better, on/off throttle transitions feel better, and there's less vibration in the cabin.
