Decided to align the front hood properly this evening. Adjusted the two rear latches (near the windshield pillars area), then adjusted the front center latch and secondary release that's under the Porsche crest in between the headlights.

Much cleaner look and easier opening/closing now.

I'm tempted to run a backup cable from the front latch to down below the radiator, just in case I ever need an easy way to open up the hood after a cable break.

That would be a slick aftermarket kit/instruction guide (sponsors, go for it!). Would only cost pennies.

 

Fabricated an air filter for the cockpit air intake today, as the stock 928 from 1988 would otherwise just allow in unfiltered air to the passenger compartment.

Then I adjusted the parking brake. It's very convenient that the adjustment mechanism is right there under the panel next to the driver's seat. I held the main nut with a 14mm wrench while unscrewing the lock nut with a 10mm wrench. Easy.

Then I pulled the emergency brake handle up two clicks, held the parking brake cable with pliers, and tightened up the cable by "unscrewing" the main adjustment 14mm nut 1/2 turn.

Tightened up the locking nut and put the car into Neutral while parked on an incline. She began rapidly backing downhill...pulled parking brake two more clicks up...my 928 slowed but didn't stop...pulled two more clicks and she stopped cold.

Perfect.

Released the emergency brake and down she went. Repeated the above to verify that there was no braking action at three clicks.

Ideal.

Have to go to 4 clicks up on the handle before any braking action occurs, and 6 clicks up stops the 928 hard.

I can dig it!

 

Pics of this? I think only the GTS got a cabin air filter - would be good to know where and what size filter you fitted.

 

Nooooo...not taking a picture of my hack job! It's ugly. It's not professional at all, just functional up under the top of the underhood area on the passenger side (U.S. vehicle).

Took my family out to dinner this evening and enjoyed clean air, though. Nice touch.


Some home air filters can be cut to shape. Use one of those and cover the hole that's next to the passenger-side hood hinge just below the windshield.

 

No Doubt, You are a credit to 928 owners everywhere. I have enjoyed reading this thread immensely, and was pleased to find that the Odo gear was not so bad to change, I have been putting off that repair for five years. (which is kind of pathetic, since I have done the timing belt twice in that time)

Kudo to you for jumping in and just getting it done.

 

You're too kind! My general strategy is to just jump in and then get my butt kicked until I finally figure out how to do something.

Failure First! Then success.

 

That's how I know so much!

I have earned all my automotive knowledge by breaking cars in very unusual ways.

 

I replaced a fuel hose to my fuel expansion tank, and today I cut it open to dissect it. Appears to be an OEM hose from 1987 about 3/8". Looked awful on the outside, so I was surprised when I cut it open to find it looking brand new inside.

Maybe the fuel keeps it lubed and wet so that it doesn't dry out internally?

Anyway, it's nice to know that 20+ years of use don't automatically mean that all of our fuel hoses are toast, even when they look awful on the outside.

Still, I'm replacing all of my rubber fuel hoses as my new parts arrive.


Right now I'm pleased with how my 928 is running, driving, handling, operating, and sounding. The seat memory doesn't seem to be working, and the electric mirrors don't work (though they are easily adjusted manually)...but that's pretty small stuff for a project car picked up on the cheap from a Sheriff's seizure auction.

The A/C is cold, the heater is hot. The cruise control works! The motor is beautiful and purrs at idle, growls when revved, and goes! Tranny seems fine, but the shift from Park into Reverse is harsh each morning. Sunroof works, all dash gages work properly.

I may even replace the rear defrost relay with a new one so that I've got rear defrost.

All lights work, but I've got to put 30 mils of XPEL film on my foglights to protect them from debris. Rear hatch release works, rear windshield wiper works (new RainX blades all around), and no leaks.

Manual BC fire extinguisher in the Driver's side arm rest; automatic ABC Halon fire extinguisher in the engine compartment.

Bosch +4 spark plugs (love 'em!) and K&N air filter.

Rear Muffler Bypass (RMB) installed. New brake pads and turned rotors. ABS works! Radar detector installed and wired to Run power (i.e. not active when motor is off).

Wheels are aligned and shod with new Sumitomo rubber at 36 psi front and 44 psi rear per Owner's Manual (surprising pressure numbers to me, could this be a factory typo??).

New 115 Amp Bosch alternator and handmade cockpit air intake air filter (easy to do and very, very worthwhile). New oil pressure sender. New (and correct) front hood shocks. New aftermarket super-synthetic odometer gear (this puppy will have the odometer outlasting the car!). New timing belt, oil change, tranny fluid change, differential fluid change. Multiple vacuum leaks fixed. Working CD player, radio (even fixed the windshield antenna cable link), clock (on stereo), compass (internal to the detector), and speakers.

New thinner, shorter, wider, center rear-view mirror (moved up higher to negate 928 blind spot and improve forward vision area). New doorcheck stops and new horn/defrost relay.

Shoot, I may start doing some minor cosmetic updates now that the shark is generally functional now! She's starting to be quite the pleasant driving experience. My kids dig the two back seats...just their size!

 

Damn good list given you started working on the car less than 1 month ago

Which Sumitomo's did you go with? The HTRZ III's are getting a pretty good rap on other rennlist forums, unlike previous generations of Sumitomo.

 

What hole is that?

 

I had good luck filtering just the small red circled area in 12, but to do it "right" you'll want to fully filter the air going into 16 & 17.

 

Yikes! I don't really know...they say "Sumitomo ZR16" on them.

 

If it works for you

However placing a filter there has no effect. That hole is for the washer hoses and wires for the heated nozzles and engine bay light. The blower sucks air in through the recirculation box, either from inside of outside. The outside passage is *I think* somewhere between the firewall and the right wheel well. 16 and 17 are the outlets on your dash, not inlets. Some people who don't have a factory pollen filter installed (GTS), installed a filter in front of the evaporator, so in the main HVAC housing (see pic).

 

It definitely works for me. By coincidence I had some pungent silicon gel under the hood, and the installation of my filter completely blocked it from the cockpit.

My 88 is different from the factory diagram of the '91 model shown on this thread.

The air input hole is rectangular, as appears in that '91 giagram, but there is also an additional round hole just above it (not shown in daigram, shown in my pic below, though) for the washer hoses and engine bay light.

This entire area is just above the blower, and just behind the blower under the passenger/right-side fender should be the air input (which is why my simple filter works).

 

Well, my back corner driver-side red driving light went out today, but it wasn't the bulb. As I was tracing the wiring from the bulb socket (that had 0 volts), I must have pulled the right wire because the light came on.

I bet that I end up running my own wires to that socket, eventually.

Replaced both of my fog light bulbs (one died, so changed both) and noticed that I have two different styles of fog light lenses, each with a different light pattern and diffusion scheme.

Ugh. I just assumed that I had fog light bulbs of different types or different ages before...but using two new H3 bulbs of the same type (Silvania) shows the difference in the lenses.

That won't be cheap to fix.


Oh well.
