Going to look at a fantastic 1973 911S tomorrow. Need a bit of advice.

Great thread. Beautiful work. Beautiful car.

One thing's for certain Ravi, you know your car. You know what you've got. That's worth it's weight in gold.

(and thanks for sharing your journey Ravi)

Ravi… congratulations on the completion of your restored 1973 911s..... well done

In her natural habitat today at the Whaletail BBQ and swap meet. Good drive out and even got to use the heat. Both door seals are whistling at the A-pillar, so I'm going to have to check that out. A lot of breeze through the speaker grill too when doing 100 km/h. Is that normal? Finally when I got home, I noticed subtle white smoke at idle with bigger puffs on revving. Never noticed that before. Any ideas? Oil temp was 185 on the drive and maybe 205 after idling in the driveway for 15 minutes while I checked various things out after the drive. Oil level is on the low end of the dipstick, at idle, engine warm and on a level surface. Pretty sure it has dropped a touch since I have been driving.

I now have about 200 miles on the motor and haven't revved past 5k on the road, though it was run in and dyno'd all the way up to redline.

If you don't have a speaker to fill that space, yes it is common. You need to cover that hole underneath the speaker grill with some sort of material to get rid of that wind sound.

What a trip it's been . . .

. . . and good on you for driving it

Thanks. Good to know. Might stick some 3M dum dum in there as that is exactly where the noise comes from.

Have bigger problems right now. Car barely noticably smokes at idle but leaves a good grey-white cloud on acceleration. Looks not bad at cruise. And I lost a quart and change of oil over the 200 miles I’ve driven it. Almost all during yesterdays 150 mile trip I think as it seemed OK when I checked it half way there and I only noticed the smoking when I pulled up in the driveway.

Pulling the plugs this morning to see what’s up.

[NorthernThrux]

Somebody needs to talk me out of jumping off a tall building.

Here are the plugs. I cleaned #4 with a wire brush but it was the same as 2, 3 and 6. Rich. 5 looks normal to lean. And 1 has OIL and was also running rich judging by the soot. That’s where my quart of oil has gone. Looks like the oil ring given the smoke under acceleration observation? Just frigging shoot me. After 7 years I got to drive it 220 miles.

Robert thinks it is actually ignition (or did he say injection?) related. Ken will be here Tuesday morning to pick up the car and take it to his shop on a trailer. Not sure about that diagnosis, but he’s the expert.

[frederik]

Man I feel for you. Hopefully it’s only an adjustment issue (although that doesn’t explain the excessive oil consumption...) and Robert will be able to get it fixed soon.

[NorthernThrux]

Update: Car was picked up on Tuesday morning by Ken and the motor completely torn down by this morning. When they split the case they found that the updated bypass valve was the issue. Robert found the valve had jammed itself fully closed. He had to drive it out with a long drift. Probably a grain of something somehow wedged itself jamming the valve. Could have come from anywhere. Perhaps manufacturing dust or weld slag from the new hard lines or a rubber component from soft lines etc etc.. anyone’s guess. He assumes from something new because the motor ran 25hrs on the bench without any issues.

So... The motor was having oil cavitation issues, filling the engine case and forcing oil past the rings...hence the smoke ..,

Motor will be put back together and run in on the dyno by next week.

So no cost other than a few sleepless nights and the loss of a gorgeous driving week, but the fall colours are yet to come.
