Dropped off the fuel distributor for Tony to look at. BTW, happy birthday, Tony.

For sure the air metering plate was misaligned and the microswitch or contacts for running the fuel pump has not worked in a while.

One of the items we talked about was the frequency valve. Not sure how one tests the f-valve. Are these things so bullet-proof that they never fail and never need tested?

Also does anyone know what frequency the valve runs at?

We tried powering a f-valve using an EP26 flasher relay. But the EP26 only operates at 1.2Hz. My guess is the f-valve runs at least 100Hz, maybe higher.

Also we do not know how much voltage is applied to the f-valve. With our EP26 driving at 14V, the f-valve got real hot. I'm guessing 6V or lower is applied to the f-valve from the oxygen sensor control unit.

I bought new engine tin seals but the rear+sides piece looks different than what is OEM. The OEM seals have a double flap and this new one turns the corners to the sides.

The channels in the car do not turn the corner. Do I cut this piece to fit in the rear and the sides? Is this the correct part? Not sure how to install this.

Hey, Spoke: Sorry I didn't see your question RE: engine compartment seal earlier. Your piece appears correct to me. As many others have mentioned, it's a ***** to install. I remember clearly, my fingers were numb for 8 days following my installation.

I used a large flat screwdriver to pry open just a bit the tracks at the curved corners, and I had to leave a bit of slack in the rubber to make the distance around the corner while maintaining the proper shape to make the seal. I also lubed the rubber with Aerospace 303 to assist. I think I pressed the rubber into the gap, rather than sliding it that superlong length, and I'm sure I used the large flat screwdriver to assist. I slid the rubber just a bit as necessary, then after the entire position looked right, I used a hard wooden dowel and hammer on the track to close the gap that I had opened up with cut the tiny bit extra off both ends, ensuring it fit and overlapped properly with the front seal. It took me about 3 hours to do both seals. Hope this helps.

Thanks for the info. Just pulled the rubber seals off. Much easier than I expected. The rubber seal adjacent to the turbo was hard as a rock and came out in pieces.

I'll need to replace the insulation on the cabin side. What type of insulation do guys use today for insulation?

Met with Mark and Scott at their shop this week to discuss items moving forward.
Some of the items:
P&C: Pistons out of round; Cylinders worn; Will replace with new. Scott says go bigger. Will try to get the HP from 280 stock to 330.
Heads will need reworked; new valves; new valve guides; repair #2 spark plug that I crossthreaded.
Rockers will be refurbished
New Pauter rods
New cams
New head studs
New oil pump
New heat exchangers/exhaust
New cam sprockets
New turbo
Inspect/polish crankshaft
Distributor: Will look for a replacement push/pull advance can or go with crank fired ignition.
Scott wants the oil cooler and oil tank out of the chassis for deep cleaning.

I'm sure I fogot things.

Great restoration project, Spoke!

I am loving driving my 930 after a similar restoration to yours (I did go Haltech EFI). Mine took 3.5 years for most of the usual reasons and I still have some small things left to do, like A/C, lol. It was so worth it though.

Parts are ordered for the transmission and engine.

I've been consumed with trying to box the brake calipers to ship to PMB.

As with everything I've over engineered the shipping to fabricate custom made shipping boxes. With a bunch of cardboard (most donated by Amazon) and hot melt glue each caliper will have its own shipping box.

Way over-kill, Wrap them in the Amazon Heavy Paper everybody gets, put them in a USPS Medium Flat-Rate Box and be done with it. If you worry about breaking bleeder screws off, take them out. If there is still fluid coming out, put the a gallon freezer bag first.

Absolutely agree. My paranoia of something bad happening to the calipers in shipping drove me to do the boxes. Each box took about 1 movie's time to complete. Total cost to me is one bag of 50 hot melt sticks. Also go rid of a lot of cardboard from stuff shipped to me.

I am very creative with cardboard and hot melt glue. I used cardboard to do the base for scenery on my model railroad. Everything shown painted green is cardboard. One picture shows some of the cardboard framework to support the scenery. I'm able to make I beams with cardboard which are quite strong.

Yeah, Mark suggested bubble wrap. I used bubble wrap for 914 calipers before but I had none available and had a ton of boxes available for free. The 930 calipers are huge. They are 11 inches long (w/o the connecting pipe) and the large flat rate boxes are 12 in leaving just 1/2 inch on either side. That's why I did 2 boxes at diagonals.

Also had to remove the short connecting pipe between the caliper halves. I couldn't place the caliper in the box w/o the pipe hitting the box.

BTW, according to USPS tracking all calipers arrived at PMB but they were closed on Sat so will be delivered on Monday.

porschedude996 04-20-2025 10:09 AM

My other thought is the free USPS boxes make great packaging that can be placed to cushion the item being shipped.

porschedude996 04-20-2025 10:11 AM

My other thought is to use USPS Boxes internally of the outside box as packing.

Jerry,

You dropped off your 930 AFM unit 3 months ago and did not leave any address or telephone # to contact you. I found the problem and fixed it 2 weeks later. Do you want me to send the AFM to Mark Epstein or you will pick it up? The service is FREE but I will charge you for STORAGE fee. You owe me a cup of black coffee from Dunkin Donuts no cream.

The driver side rear bearings and races are out and the swing arm is cleaned up. Now to give to someone who is more talented than I to have the new bearings pressed in. Probably check with John Butz as he did the passenger side bearings a few years ago. At that time the inner bearing had blown apart. This work is just preventative.
