Re: 1984 633CSi Rises again!

Nice work, Song! =D> Did you bleed the clutch, too? :-" Haha, if I only had a clutch to even worry about. I keep waffling about the cost and benefit of a manual swap. I use this car for commuting and stop and go traffic is best handled with an auto. I have a manual car with a 6 speed (S2000) a...

Brake Lines and Bleed, Tire Rotation

Today I decided to change all of my rubber brake lines. I purchased a complete kit manufactured by Corteco which also included fluid for about $73 from FCP Euro. This seems like a great deal! (https://www.fcpeuro.com/products/bmw-comprehensive-brake-hose-kit-corteco-19025516kt1). I also needed to ro...

Re: 1980 633 safari - front spoiler complete

I second Bobbo on the great and unique color combo of the spoiler, body and stripes!
I looked at the auction pics and man, someone took a lot of time to take and post so many detailed pics. Congrats on getting into a fun car and many the years of blissful motoring ahead!

Re: '83 633CSi - running so rich it stalls

The silver relay would not have been done to your car but the coolant temp sensor test does apply. Same location on the thermostat housing but may be different ecu input terminal Ralph For what it's worth, I have completely removed the mystery silver relay and driven my car the better part of 510 m...

Re: What did you do to your E24 today?

I really didn't do this - I had it done for me... My wife and I sold our house in Michigan and we're roaming the country - currently Florida - in search of a new home. So I'm currently houseless, garageless, and almost completely tool-less. While heading to a new rental in Port Charlotte at nearly ...

Door Handle, Bump Stops and Alternate use for Grommet

As planned a few parts arrived as scheduled and I installed them all while dodging the on-again and off-again rain. First order of business was replacing my broken interior door handle on the passenger side. No surprises here. The tab was broken and the remains of the original grommet was in pretty ...

Gotta stop the door rattle!

Well, the silicon tubing made things noticeably better, but I still hear something going on. Looking at my old door bump stops, I think they may be compressed and shrunk, allowing the metal to metal sounds. I hopped on Pelican Part and found a decent deal on the following. Door BIts.png I'll install...

They look good. I too rate the Eastwood products very highly. I did my family Volvo SUV with the Eastwood plastic restorer and it did a great job. It's about $30 a can. I did mine at the end of 2018 and even today (2023) it still looks good! Here's a picture of the process. It's like painting parts...

Re: Rough idle/ misfire on an 85

I wanted to close the loop on the issue with my car that caused it to get towed to the shop. Turns out that I had a broken connection from harness for the temp sensor mounted in the thermostat housing cover. Way back in 1986 BMW had a technical bulletin where it had dealers install an in-line resist...

Re: 1984 633CSi Rises again!

There are supposed to be grommets in those holes, and they are still available for cheap. The grommets are a harder plastic, and in addition to stopping the rattling they also “tighten up” the feel of the interior door handles and the door lock knobs. Takes all the play out of the system. But the s...

Anti-Rattle and a Drop

I've noticed rattling noises in my doors when I am on a bumpy road. The recent incessant rains in California has done a number on the roads. There are potholes and damage everywhere making for a rough ride in spots. I decided to look inside my doors for any loose bits. I'm glad to report that the wi...

Capturing a Milestone - 200K

I purchased my shark way back in 2015 with about 142k showing on the odometer.

Well, last week on 1/24 it crossed a milestone. 200K.png It's runnin...

Good to have an easy solution, especially when it's something that was never listed in the official troubleshooting manual. $550 is about 4 hours labour where I live.

Does that $550 include the spark plugs? Even if it doesn't, not a bad price to find that elusive problem.
Yes it included new Bosch plugs. I asked and they were $12 each. I thought that a bit high, but ok.
