Polishing intake and cam tower
I currently have my cam tower and intake off in teh process of replacing my headgasket, and I wanted to polish the two. Can anyone give me some insight how to do so? Turbotim? I have been using hendheld sandpaper to rub them down, and its workout out pretty good thus far, but not getting the results I want before I start to use a polisher. Do I need a sander? Any insight/tips would help, thanks

I have my engine apart and have been cleaning some stuff up. I have not done too much yet on the cam housing. I used a wire brush, and a wire wheel on a drill for my intake manifold. I used a dremel also, and that works pretty well also. I tried using sandpaper, but that took too long. I would start with a wire brush, then use the sandpaper to clean it up.

Unless something happens that forces me to rip stuff apart I don't se myself doing any of this in the near future. However, if and when I do it, I want to ceramic coat the valve cover and paint the "PORSCHE" letters red. The intake and exhaust manifolds will probably get coated as well.

Simple three-step procedure. Tape off the mating surfaces to protect them. Get a buffing wheel for your rotary sander, or a drill-attachment:
1. start with rubbing compound and lots of water and go over the entire surface really well. You many need to continue with a rag and do by hand to reach the crevices between the lettering.
2. rinse off all traces of rubbing compound and use a new polishing pad with polishing compound.
3. rinse off and dry the part really well. Then finish with a chemical polishing compound like Blue Magic or Mothers. To help to pick the right compound, this stuff usually has 'ammonia' in the ingredients

Does anyone have some pictures of a polished intake manifold or cam tower that they did themselves? If so post the pics and what procedure you used.
I am also interested in this, I have a spare intake manifold that has been sitting in my garage for a while now.

To remove heavy castings.... you can use sandpaper.Strat with 80 grit and use 180 after that.
To remove light castings and heavy scratches you should use a 320 grit greaseless abrasive(red Lee compound) on a tight sewn buff.
To take out the light scratches from this process you can use black emery compound on a tight sewn buff.
To start the polishing process..... use tripoli on a tight or loose sewn buff.
To finish it off you can use white compound on a loose sewn buff.
To clean all the fingerprints, smudges, grease, etc..... off sprinkle some cornstarch on your parts and wipe off with some soft rags.

I went ahead last night and tried polishing a small area of my intake. It worked pretty well. I was getting tired so I used the wire wheel and polishing compound before I had it completely smooth. I just used 100 and 150 grit paper on it. I am going to slowely work on it and get as much of the rough casting out that I can. With a little more work and using the different grades of sand paper and emery cloth I should be able to get it really smooth..It is going to take some time though.... I kind of like how it looked before I used the compound on it, just the smooth Aluminium.
