Rant

[930cabman]

I have been a VW and Porsche guy since my 16th birthday in 1968 and have the highest regard for German engineering, it is my opinion there is no better.

side note: our own US made Chevrolet Corvette is by far the "best value" sporting type machine there is, but I would never have one in my stable.

Our '75 911S recently developed a tick, tick, tick on acceleration. I have heard of the cylinder head stud issue for sometime now, but at this point it's in my lap. Really I am thinking WTF, our beloved Porsche who created the flat 12 cylinder that was untouchable in the '70's could mass produce an engine where the head studs would shear/snap/break from failure. Again WTF. I suggest we contact the factory for a mass recall dating back to ......

I am sure the repair tab will be in the thousands for ???? the engine is running just fine, but leaking from the cylinder/head junction because some idiot did not know the steel or whatever the material is would fail??

Is the repair for this mess a simple 1020 grade steel stud?? not too soft and not too hard??

Quite the rant. Not sure if you are joking or not. This ain't big news.

There are several studs that can be used but make sure they are meant for the specific application.

Bob, is this what you mean?

Come on...


We know the studs need to be coated, top to bottom, fully...

You can find a new pic, right?

Ain't new news is the correct term. It's big news to you, unfortunately.

Those guys do sit-ups, I bet.

Unlikely. I've been doing more sit-ups lately, and I surely do NOT have a big smile on my face. The only time I have a grin like that on my face is after a week of sitting on the couch drinking beer...

Pazuzu, can't believe it took you this long to finally realize that.
It's all hype, just IMO. The list is too long.

OP, it could be something other than your studs. Mid-year 2.7's have a tendency to pull the head studs clear out of their magnesium cases.

LOL, throw salt on a wound, why don't ya?!

Yeah all cars have some Achilles heel of some sort. I know my BMW motorcycles have long had the threaded post for points at the very end of a camshaft running along the top of the motor. Just over tighten that and feel your heart stop on shearing...

Like a Ford fender in the rust belt?

My 4Runners antenna broke after 180k miles...probably made in the USA (the antenna)

PS can't wait to check my Studs!

When should I expect you, Rich?!?!

[Rich Gas]

Ron, I don't know if I have an instrument that big!!!

[Rawknees'Turbo]

Let's paaarrr taaaayyyy!!!

[Elombard]

Looking at it half glass full.....the studs lasted 40 years, most cars from 77' are dust. That is pretty good engineering.

I dont know what to say about the rest of this conversation :-)

German crap-my '67 Corvette's cylinder heads are as securely attached today as they were in '67.

[Rawknees'Turbo]

Two areas in which Porsche, at least the 911 side of the shed, has excelled at suckage = headstuds (including non-reinforced bosses in mag cases) and wiring/electrical best (worst?!) practices! Oh, and climate control, buttofcourse! And oh, oh - oil retention!

[930cabman]

True, I may be behind the curve a bit, none of that makes it ok.

It sounds as though a "normal" steel stud is the fix? and while we are in there, of course thousands and thousands later.

Really I cannot complain much, bought the rust free solid, straight somewhat original car in Vegas and drove her home to Buffalo without incident six or seven years ago.

Still, why would the engineers simply have not used a mild steel??

Yes, but the crank fell out so the point is moot
