No prob, will do tonight. I stuffed that stuff in a box and have not studied it yet.

 

i talked with sean and he doesnt feel this is the issue but im just trying to get a visual since i left his shop before the cams went in and that section was completed

you could start over and do a video of the entire build!

 

Not sure what side this is but here are some pics. Gasket is upside down.

 

thanx for the pics. gives a better idea . i really dont see how the gasket could be installed incorrectly. whenyou say the gasket is upside down you mean im looking at it from the upside down position right? not that its installed backwards

 

The gasket is 3 layers with the middle being thicker. The top has different lowered crush channels than the bottom and the middle layer is flat. There is a hole for the sensor plug in thingy to flow oil on one side that would be blocked if the gasket were installed upside down. The gasket does fit if you install it upside down, it is installed upside down in the picture because I was handling the lifters earlier. You can see the hole in the gasket on the middle left where there is just flat aluminum under the hole. There are two holes underneath the sensor. One has a spring and a check valve and flows to the side, the other is underneath it. The open hole would certainly be blocked if the gasket were installed upside down. I believe that your concern is a possibility.

 

Update. I spent some time cleaning my pistons and studying the installation procedure. There are some special tools required but I think I have a ring compressor that will work. I have been worrying that I didn't lubricate my stretch bolt seals well enough and they may have bunched up and torn, so I took one of the outside bolts out. I have some extra seals that came with the gasket kit anyways. The seals look great so I am content with that. I should be able to put my pistons in pretty soon. I want to torque my crank pulley but there is red loctite on the threads so I am going to pick up a thread chaser tomorrow.

 

Subscribed!

So glad to finally see one of these getting documented Any chance you could list your source materials you used for instruction, and any specialty tools you had to buy or make?

Thanks!

 

we always use 574 and i believe that is what Porsche calls for as well

putting in the center pistons is by far the trickiest part of the build, i def recommend getting the correct ring compressor and cylinder press tool kit that comes with the housing spacers. stomski racing makes these.

Sure. My sources are:
1. The service manual is the first thing I refer to. It has good info but it can be a bit unclear.
2. Pfixit.com has a great DIY video for building 964 aircooled motor. Lucky for me our cars use the 964 case so the video is perfect. Just a few differences with the newer version. It costs $16 to see chapter 2 but is well worth it as it took out all the guess work for building the crank case.
3. I am drawing off of my own personal experience with building my own engines. I've made some mistakes in the past that I had to redo so I know what works and what does not. I also took the motor apart myself and took notes.
4. I got a few tips from builders and had machine shops work on certain parts.

No super special tools needed that I couldn't work around so far. I think I have a ring compressor that will work. I plan to have EBS Racing set my cams later. I know there are tools needed for that job.

 

Those look nice. I think I have a redneck workaround that involves a $20 ring compressor, a freezer, an oven, a rubber mallett, and vise grip pliers. I am planning on coating my base gasket in Permatex copper spray-a-gasket. I've had good luck with it before on my motorcycles. Any reason I shouldn't?

 

Made the attempt at installing one cylinder bank. I struggled with it for a while until I figured out how to pop in the piston clips consistently. I installed both outside cylinders and was ready to slide the middle liner in but the oil that spilled from the pistons was wicking away the copper gasket spray that I put on the base gasket. I prefer that spray on the base gaskets I have installed before but now I am going to have to figure something else out. I am taking the cylinders back apart. I have that part figured out so it won't be too bad next time. I am going to focus my time on finishing my heads so I can bolt the whole thing down all at once.

 

I was able to get one side installed. I used the copper base gasket spray again and was more careful this time not to spill oil on it. I contacted vr6tee through PM and asked him how he installed his cylinders on his awesome 997 build. He had a great simple ring compressor idea. Special tools needed to install the cylinders: one regular ring compressor, one hose clamp, a screw driver, and a rubber mallett. To do this job you need steady hands and a lot of patience. You have to get good at popping in the piston circlips before you start or you will never get them in while attatched to the rods. I was able to carefully slip the middle liner in using the hose clamp to compress the rings and the rubber mallett to knock it in. I forgot to get a picture of the middle liner install as I was really focused trying to keep it all lined up. I will get one when I do the other side.

 

Thanks for the detail! I ran across a YouTube channel "Speed Academy", he has a series on a 930 that he is having built at a place called www.turbokraft.com, pretty decent tear-down and build videos. Not sure how relevant they are to the 996 but the last build covers most of the cam timing, not a ton of detail but good overall process, you might pick up something from them.

 

Awesome build!

I'm gonna use this!

 

I would be careful, the fun police will be all over your *** (see picture).


I would love to time my own cams but it is not economical to buy the tools when I was quoted $200 for a shop to do the job.
