Jun 22, 2011 update to the Porsche 911 Carrera project car

Oh, Snap!

The Porsche still looks good, but it's currently on the DL.
See the empty hole on the right? There should be a cylinder head stud in there.
The clutch has seen better days, and a new one from Spec has already been ordered.

What made it really sting is that someone had removed the end of the stud and reinstalled the valve cover. So much for that pre-purchase inspection.

The latest garage session with the Porsche didn’t exactly go as planned. We started the day looking at a valve adjustment, which is regular maintenance on these cars.

When we removed the lower-right valve cover, however, we received some bad news: a broken cylinder head stud. What made it really sting is that someone had removed the end of the stud and reinstalled the valve cover. So much for that pre-purchase inspection.

If there’s a bright side to all of this, we needed to remove the engine anyway to replace the clutch—it’s really on its last legs. This will also give us a chance to right a few small wrongs that we have noticed.

The engine is already out of the Porsche, and parts have been ordered. We have ARP studs and a Spec clutch on the way. Soon we’ll order the various gaskets and bits that we also need, and we’ve already talked to JB Racing about some head freshening.

The plan is to have the car back together in time for Porsche Parade. Tick, tick.

Hey, dudes! Better order a flywheel, too.

Thanks. It's been sent out for machining. Should be good as new.

I chose ARP head studs when I rebuilt my '78 911SC engine. Once it was done (sigh) a trusted mechanic suggested I check the torque on my studs at least once a year. Sad to say he was right. Four of my exhaust studs have a tendency to loosen. Now I re-torque the exhaust studs every fall while changing my oil prior to putting the car away for the winter.

The mechanic who tipped me off to this issue recommends Porsche 993 or Raceware on early 911 engines.

Glad to see you're enjoying your car.
