SAI Pump Wire Insulation

A known weakness, the insulation falls of the wires leading to the SAI pump.  I addressed it by knocking off the old insulation and replacing it with Ancor marine-grade shrink wrap (1/4").  Not only did this shrink wrap seem extra sturdy, but it shrinks to 1/3 it's original diameter.  This allows it to clear the collar on the plug and still shrink tight around the wire.  But next time, I would probably just replace the wires.

Engine Pad Replacement

Out with the old

As is common, my 993's engine pad was in sad shape.  There is no easier time to replace it than when the engine is out...

The Fan/Fan Housing Saga

Broken Blade Tip

At the beginning of my top-end rebuild, I was excited about the opportunity to refinish my decrepit-looking 911 engine cooling fan and housing.  Once they were removed, however, I realized they were both damaged beyond repair.

The Damage

The fan was missing two blade tips, and the fan housing was cracked around the alternator mount.  So I decided to bite the bullet and order both new.  I figured it would at least be easy, but Porsche had something else in store for me...

Plated!

Progress has been slow over the last few months (three months since the last post!?!), but it hasn't completely ground to a halt.  The big news this weekend - parts are back from being yellow-zinc plated!

The freshly plated oil-filler cap might be the first part I have re-installed, which seems like a landmark worth capturing :-).

Porsche 993 Top-End Machine Shop Work

Return Shipment

I am way behind on updating the blog. I shipped the cylinder heads for valve-guide replacements almost three months ago, and they came back the day before my daughter was born (the original deadline for finishing the project - oh well).

DIY Soda Blasting

I have sent several batches of parts to a soda blasting service, and been very happy with the results (see here). However, for a couple of reasons I decided that it would be nice to have the capability at home.

There is a fair amount of information on the web, but I never could find a clear guide that fit my needs and circumstances.  Here I will document what worked well for me.

Plastic Repair

Recent progress on Ella has been slow, as usual, but I figure if it hasn't come to a complete halt, then everything is ok ;-).

The top-end machine work is done and should be shipped back from Rennsport Systems next week.  They also are doing a distributor rebuild for me.

I also shipped out my mufflers for a Fister Stage 3 conversion and ceramic coat -- I can't wait to see how they look and even more how they sound!

That stuff will all be back before I am ready to start re-assembly -- the list of "while I'm in there" tasks to do is still long.  One item on that list was repairing a cracked plastic wheel liner and a broken under-body tray.

The under-body tray (Porsche part number 99350412900) was functional and out of sight, so I couldn't justify the $300 to replace it.  However, I also didn't like it being broken.  Last year I fixed my kids' plastic slide using fiberglass tape and plastic epoxy, and I figured the same would work on this part.  Here are a few before and after photos.
