What did you do with/to your Boxster today?

Might be helpful for anyone wondering how deep to drill. Measure measure measure. The last thing you want to do is drill too deep and into the block.

Few pics attached for ref. It's a slow process but satisfying when done. I cleaned the surface but I can still see stuff / staining on the surface. I can feel any lips but should I keep cleaning and get shiny metal or is it good enough? I mean how clean does it need to be? This is after wet 240 sandpaper and steel wool. I didn't go too crazy but as I've done this much right it would be shame to mess up on the gasket faces.

Nice work, Traco. As long as the surface feels smooth when you drag your fingers over it you should be good. For future reference, don't use sandpaper or steel wool on aluminum mating surfaces. It's too easy to wear it down unevenly and you won't have a true flat surface. I use Scotch-Brite and brake cleaner.

Cheers Piper. I did scrub it with a green scotch pad and cleaner. There was the odd build up that I hit lightly with the steel wool then wet and dry lightly. I was afarid to go too hard as you mentioned that's why I was wondering how clean it needs to be.

Should I attempt to clean the ports and if so how or would I be asking for trouble there for little or no benefit?

Also any thoughts on reassembly with ceramic grease. Rated for 1500C and I've seen it mentioned on aircraft assemblies. As it's non conductive it might reduce the galvanic corrosion between the steel and aluminium. If I keep an eye on the bolts for torque at each oil change it might be an interesting experiment for a few years down the road??

Throttle body cleaned - it did need a celaning indeed the car runs soooo much better now and feels like there is more power thru out the rev spectrum
