Default 993 Yearly Maintenance Brainstorm - the Fastidious Edition

Edit - See additions from feedback on this thread at bottom of list.

Assuming us 993 owners had endless time to throw at car maintenance, what would we possibly do as part of a yearly routine? I’ve started a list here based on some searches and tried to make it as comprehensive as possible. What am I missing?

If it's not obvious, I'm looking to spend some quality time in the garage once it cools off.

Readout of DME, ABS, Climate, Alarm fault codes
Engine Oil / Filter Change
Gearbox Oil Change (every few years)
Check all Belts for wear and proper tension
Inspect the oil cooler and AC condenser for debris
Inspect the valve cover and chain cover seals
Inspect the brake pads, rotors, lines
Flush brakes with fresh fluid
Flush clutch with fresh fluid
Inspect the air filter
Inspect poller filters
Inspect the suspension
Inspect engine mounts for leaks or excess sagging
Inspect shift linkage (car still has the original forward shift rod)
Inspect boots of ball joints, drive shafts, etc
Inflate and inspect tires
Remove and clean wheels
Check all bulbs and light function
Clean MAF
Clean ISV
Lube door hinges
Lube frunk, engine compartment, fuel door latches and hinges
Replace wiper inserts
Top off washer fluid
Top of battery with distilled water
Test battery voltage at rest
Test battery voltage while cranking
Test all 3 fan resistors
Test varioram servos
Install new batteries in the alarm remotes + replace spare batteries in glove box
Test secondary distributor rotor
Pour in some Lubro moly jectron
Inspect windshield seal area for rust
Lube windshield seal with some ice wax
Check / adjust alignment of targa roof
Verify tightness of targa axle screws
Check all targa water drains work



Maybe on the list:
Replace SAI valve (every few years)
Flush power steering system


Additions from the thread:
Remove windshield and rear window seal, inspect for rust, clean, replace (every few years)
Remove headlights, clean brackets, inspect for rust
lubricate clutch slave cylinder pin
Clean pedal box and inspect clutch master cylinder boot
inspect fuel lines from the fuel rails back to the hard fuel line on the firewall
Check CV joint bellows for cracks

Do you have to do it in that order?

That' s a great list. Some of those items could maybe go on a every two, 3 or 5 year list though. I think ideally follow the typical milage maintenance and then ad a list like this in the background. I think if you can do all that every year would be awesome but you might get fired and or divorced

I'd ad remove front and rear window seals and clean channels, once every few years. I replaced my seals last year. The channel was full of crud. Don't think anyone had ever done that.

Pop out the headlights, clean brackets, and inspect for rust.

Hah - not going to do it in this order, and yes, I'll need to strike a balance with those pesky work, wife, and family things. Luckily, a lot of these things are quick jobs (inspect stuff, replace batteries, lube latches, add jectron, etc).

Good call on the seal.

I would tear the engine down to the crank just to make sure it all looks good!

One maintenance item that is is not regularly done but I do because of the lift is lubricate clutch slave cylinder pin. For some reason, the grease on the pin does not last very long, and then your get that nice squeaking noise when pressing down on the clutch.

Clean pedal box and inspect clutch master cylinder boot?

Fuel line check is good - there is a spot that I have seen issues with on the 964's that I think will start to emerge with the 993's - the hard line from the fuel pump terminates in a flex hose on the rear firewall of the engine bay. That flex hose (about 8" long) seems to get hard and can crack due to the heat cycles. I have seen them split wide open - and replacing them requires a lift because you need the swing room due to the threading of the hard line through some very tight spots. So inspect fuel lines from the fuel rails back to the hard fuel line on the firewall is a good one.

Cheers,

Mike

Plan is to not tear down the engine exactly, but remove any and all plated fasteners for re-plating in original cadmium yearly for corrosion protection. None of that eco-junk yellow zinc in my car.

Good call on the clutch, pedal box, and fuel line info. Will add to the list.

I do a yearly: Check CV joint bellows for cracks.

Other than that, it's a good list.
