If anybody knows how to get in touch with Larry, I need an assist call from him. I'm trying to put the Type IV valve covers he made on my car, and I believe I have the wrong studs.

If anybody's done this conversion from the bail-type covers to studded ones, give a yell. Likewise, if anybody's got Larry's number and can ask him to call me, I'd appreciate the help ...

I decided to do this at the firehouse, so I'll be here until I get the right answer. One of my old VCs is still useful, and I haven't monkeyed with that side yet, but I'm short a gasket to put back on the side I'm working on. I glued the new gaskets into the new covers back in May.

I'm retarded for not being prepared. Such is my luck ...

On my similar covers I replaced the nuts holding the rockers on with longer coupling nuts. Then bolts go through the valve covers into the coupling nuts.

You have to be careful that the bolts are not too long and bottom out before the covers are tight.

I am a little concerned that the coupling nuts are softer material than the original nuts but that may be offset by them engaging more threads.

After trying o-rings and then steel washers with rubber around the hole under the bolt heads I am now trying out slices of 5/16" fuel line. I was amazed at how much a foot long piece cost. I should have asked first. I only needed an inch or two.
Here's the situation. I thought I had two long studs and two short studs, a set of coppers from Danny and the right hardware to press the covers neatly against the spacer nuts inside -- but the short studs don't seem like they're long enough to work correctly.

Larry is going to send me the instruction sheet (I swear I've had it with the parts for a frigging year now, and it just wasn't there) again on e-mail. He's in the middle of some SoCal desert right now, but still took the time to answer a phone call from a dummy.

So ... For now, the car is safely indoors in a secure building, I'm running calls on the fire truck, and maybe tomorrow I can get it fixed properly.

I have my trusty wrenches, my .006 feeler, some RTV in case I have to put the old gaskets back on ... and a cigar for when I have to take a step back. Meanwhile, the citizens of my little burg will have an unscheduled fireman running around on a truck for as long as it takes Larry to send me some smoke signals. (:

Naaah.

I've salvaged the old gasket and gotten everything back to what I had, minus the back section of the body. I'll be okay to get it home, at least. It's 3:30 in the morning here now, and I'm shot. I'll re-attack later today.

(The fire trucks here are red, by the way. Yellow ones just need more sun before they ripen up.)

Jack, you're sooo right. I made it home, barely. The OP light came on at about 100 meters to the garage door. I coasted in and shut'er down ... At least there won't be a huge mess on the garage floor.

That patch-job on 1/2 side gasket didn't hold. She was smoking like Manfred von Richtofen on his last ride. Sucks, but what'cha gonna do?

At least the repair is going to be simple, eh? Everything else is perfect.
Cory, these are the instructions I got from Larry. I found that the shoter stud barely catches the nut at first. Once you start to tighten things up the gasket will compress enough to get the nut to thread.

TYPE IV Valve Covers
Go to your local hardware store and purchase a small bottle of Weldwood Contact cement (small bottles have an applicator brush attached to the inner lid. Also, buy a small tube of Loctite. (Loctite comes in several strengths, medium holding power is fine)
Remove your existing valve covers, if you have stock covers, also remove the bails.
Remove the 4 nuts holding your rocker shaft to your cylinder head.
Remove the rocker arm shaft then remove the (2) outer rocker shaft mounting studs. (You can double nut the studs or, use a pair of vice grips) Insert the new rocker arm studs making sure that the longer stud is inserted into the head on the left side of the engine (see below)
(Look at the valve cover and note the stud hole to the left of the letter "P" of the word Porsche. A long stud must be inserted into the head so it protrudes through that hole.. The short stud is inserted into the head on the opposite end or, where it will protrude through the hole in the valve cover to the right of the letter "E" of the word "Porsche")
Double nut the new step studs and tighten the double nuts against each other. Install via a wrench on the outer double nut and make sure the stud has seated correctly by ensuring that the larger threads of the stud are flush with the rocker arm stands.

Re-install your rocker arms and tighten the 2 inner and the 2 outer nuts that secure the rocker to the head.

Now is a good time to adjust your valves.
Apply a thin coat of contact cement on the valve cover in the gasket groove and also apply a thin coat to one side of the cork gasket. Set these aside for at least 8 to 10 minutes (longer if cold weather) to allow the glue to become tacky. Insert the gasket into the groove of the Valve Cover, glue to glue side.
If they don't stick, you didn't let them dry long enough. (Glue residue can be cleaned with Lacquer Thinner, Goof off or Brake Clean)
Clean the gasket mating surface on the cylinder head making sure that no old gasket or oil remains.
Install the Valve Cover and make sure the gasket seats around the cylinder head. Next, install the copper washer with the groove facing out, next comes the aluminum washer and finally the nut.
Using the brush in the lid of the cement bottle, dab a small amount of contact cement on the exposed stud and install the nut, tightening to around 8 to 10 ft. pounds. (Don
Thanks, Jeff. The covers are not going onto my engine. I'm shipping them to a friend for his car.

I got the same instructions from Larry a couple days ago, and I think I have something different than they were intended for. I tried a series of combinations of things to make them work, and I came up empty-handed. I'm just not going to keep banging my head against a wall and hoping they eventually fit.

If I leave them on the shelf in the garage, they'll tempt me and I'm sure I'd eventually mess them up. Better that I move them along to a car they'll fit on out of the box.
