Align it - make it straight!

In the three-plus years I've had my car, I've never had an alignment done. Goodness knows I've changed a lot of suspension pieces - like all of them. I came across a Living Social deal for a 4-wheel alignment for $55 and though, what the heck. So here's my car getting its first alignment. Screen Sho...

Do the colors match?

So it's been three days since I painted my front air dam. The paint appears to have cured quite well and I've inspected the air dam closely with a flashlight at night and there's not a single visible spec of dirt from the re-paint. I am shocked. I won't get put this on until the weekend, but in the ...

Re: 1984 633CSi Rises again!

Thanks for the details Song. A couple of pics to show the bracketry for the air dam. Hope this helps you. Ralph Airdam Brackets.JPGAirdam Brackets2.JPG Excellent Ralph! That's a lot of hardware to hold up some plastic! Lol. With those pics, I'll be able to figure all this out I am sure. Many thanks...

Re: 1984 633CSi Rises again!

Are you sure that's LVLP, and not HVLP (High Volume Low Pressure)? Because that's the industry standard now. I've never heard of LVLP. The HVLP guns deliver more paint with very little overspray. I am very sure. I struggled with the consideration of a HVLP gun for a long time. You see, my compresso...

Re: 1984 633CSi Rises again!

My best piece of advice is make sure you have a very good air filration system. You want clean, dry air for the sprayer. I sold that spoiler to Song last year as it was the last one I had for sale and I really don't expect to see anymore come up at the scrap yards. He knew I didn't want to ship it ...

Garage Sprayed 2K Paint for Airdam

So after extensive study, I decided to use a LVLP (Low volume Low Pressure) gun to paint my airdam that I got from Ralph. You see, I have a smaller compressor and the LVLP only needed 25-40psi and 3.5cfm. Also, my understanding was that there is much less overspray with a LVLP gun. Cut to the chase,...

Re: 1984 633CSi Rises again!

I was quoted for a full repaint, glass out in Bronzit of $10,000 for labor (including some body and rust repair work) plus $5,000 for materials. I would never consider DIY on painting, especially primer, base and clears. This was not from your typical body shop but a restoration specialist with a l...

Front Spoiler and Paint - step 1

This weekend I snuck some time away to begin to prepare the front spoiler. First order of business was to repair the 2 cracks in the spoiler. I used a 3M bumper epoxy. It was a kit I got off Amazon for $6.00. That was super cheap. Spoiler.png Next, I needed paint to match it up with my car. I went t...

The Reset Light - makes no sense

So, today I thought I would reset the "Oil Service" light with one yellow LED. I read in the forum that I simply had to ground pin 7 for 3 seconds while the key is turned to position 2. Easy enough! I reset the light and now here's what I see. GreenLight.png Green makes sense, but why isn't the far ...

Re: 1984 633CSi Rises again!

Looks like your number plate has claimed a few road kills. If it's legal in Cal I would ditch it completely and replace with vinyl numbers on your new spoiler lip. Yea, that plate has seen better days, but it's the ORIGINAL plate that came on the car when new. I kinda like that it's true to the his...

Re: 1984 633CSi Rises again!

Nice airdam! :D if your service indicator lights have never come on before, it could be leaky NI cad batteries. As the SI board used NI cad batteries, unless it truly is working, it seems kinda random after long term ownership they all of sudden work. You may want to pull the cluster and make sure ...

Airdam andService Light

So a few new things have appeared for my 6'er. First is my long awaited Air Dam! This is from a 1985 M6 I believe. There are a few cracks that I need to repair and then I'll have to refinish it. As you can see, it's not a perfect match right now. Given my current schedule, it may be a long time befo...

Re: 1984 633CSi Rises again!

just a couple of comments - they don't appear to have keyed the old paint (eg using 800 grit paper) which may be part of the reason the new paint didn't stick - if you have to use a lubricant on the ARB bushings, a silicone grease (which is inert) would be better; some lithium greases may degrade t...

Massive Paint Fail

Well, if you have been following along, you know I've mentioned multiple times that I need paintwork. So what am I talking about? Well, before I acquired the car about 3 years ago, the car had a repaint. It's one of those paint jobs that I would consider a 20 footer. It looks awesome at 20 feet, but...

Wrenching on the car this weekend

My replacement part came in for my damaged tie rod. True to their word, FCP allowed me to return my loose toe rod and replaced it with a nice new Meyle. Only issue was the Meyle cost twice as much, but the warranty credited me the original part price. So I got an unintended upgrade I guess. Once aga...

Wheel swap and other fun

My front tires wear on the outside and my rear tires wear on the inside. So I decided to swap the front and rear tires today to even out the wear.

Re: Good things begin on Jan. 12, 2009!!

Right! I needed a new starter and new CV boots. Autohausz got the order and while the CV boots can be gotten for less, the shipping eats up the difference. Anyway, I'm having a shop swap out the old starter and put in the new one. I am just too damn old to fight that fight AGAIN. Twitchy backs do N...

I was going to suggest an additional heatsink, too. This one works at the original mounting position with a little modification. Good to see you posting again, Song.

Re: 1984 633CSi Rises again!

Song, did you replace your heater fan motor? After replacing these transistors multiple times I suspect that the real culprit is the old fan motors which either stick or are slow to start up and pull too much current. I replaced the heater and AC fan transistors and they both failed within a year. ...

Re: Finally! '85 635CSi - Euro-Spec-Stick!

I’d say you got a really good deal. Your car looks to be in great shape, especially the engine compartment. Good example in Northern California are $6-8K and rough ones are $4-5K. The rust in the fender is an easy fix (I had that too). I did notice the diagnostic port wasn’t in it’s normal perch. Al...
