I've heard other people comment on the difficulty of isolating oil leaks with black engines but I've painted my last 4 engines gloss black and haven't had any issues tracing leaks to their source. It's always been easy for me to see where the dust is wet vs. dry.
gray is THE SHIZZ for finding oil leaks.. the 1.5 i built, was gray, and showed every leak. i LOVED it.

I currently have 2 cans of John Deere green in my shed that I didn't know I had. So I think I have found my paint color...unless I have some others that I don't know I still have.
I cannot wait as the machinist should have me the block this week 7-25-12* and I will start going after it. I still have the taps to do all the holes. It is like waiting to open presents.

I think you'd be ok, you have such a purdy mouth that eventhough you probably say aboat, they would love you here, lol.
The solution would be buy another car. Then tear down something and play. Which, don't you have 5 or more of these cars or is that the extended family?

I started this with less money, but really wanted something better. Luckily, the machinist has a soft spot for old VW's as this is going to be just a fuzz cheaper than my last build or right at the same. I have a lot of reusable stuff, I think it was less than 50.00 per piston to coat them with both coatings. I will have the stuff together as soon as I check the ring gaps. The machinist said that he went 10 years with no issues with ring end gaps being off. Now sadly he says that it is just about every other box. Mine came with the KS pistons so I am hoping that they did a good job. I can't remember what the spec is, but from 3 years ago I am thinking it was somewhere between .015" and .020" for those rings.
Now that I know the head is not going to be done soon I may build that intake before it is done. All depends on how much wood I get split in between now and then. The good news is I have my sausage stuffing tubes ready to go for it

Hmm when I pulled the pistons from my engine I cracked the head on, the cylinder that had been getting water had .030 gap in the top ring, the thickness of a credit card.
Get this thing together man, u are the man right, can't wait to see ur intake and ur sausage funnel, let's see that sausage funnel

Well I only measured 2 rings and one was in spec at .016" and one was out at .021". Bentley said spec is .014"-.018" 5/8" down the bore. I don't know what to do yet so I gave up for this evening.
I will post pics of the stuffing tubes soon.

Here is the idea. I have been reading like an intake builder wanna be and asking the machinist with a flow bench how not to mess this up. From what I gathered, at the end of the day, whatever I do will be better than the stock intake. So goal #1 accomplished in that. Goal 2 is to do this cheaply and so far I have about 30 in the intake, 30 in the aluminum tubing, and 40 in the sausage funnels. One funnel from a speed shop was going to be around 30 here, I am ahead of the game so far. Goal 3 was accomplished in that I found the sausage funnels that had a good taper #22 and 3/4" IIRC and will pack more air in each runner and not bias it badly.
The design is to cut the funnels down on the OD to just clear the ID of the big pipe *plenum*. It only has to clear .125" or more and 2 and 3 will be cut some more as they will be close enough to hit. I'll cut the plenum in 1/2. Then the plenum will have the 4 holes cut so the runners can come through with the sausage funnels on top of them and weld the plenum back up. The bottom of the sausage funnels will be cut off to fit the aluminum tube and all sanded to promote flow. The plenum volume is 1/2 the engine displacement so roughly .8L. The runners will be either 8.25" or 9" I have some more math to do on the harmonic of it, but fairly long. That is the added benefit of putting the sausage funnels into the pipe, I won't have hood issues that way. The runners will attach to the cut up stock intake manifold ports for the first 1.5" or so. The sausage funnels will not actually be a structural piece, but just welded to the runners and the runners to the plenum.
Here are some pics. On the bottom just imagine the sausage funnels with the OD cut and inside that plenum tube instead of under it...
You can see there is a good taper in these sausage funnels.
Lastly with the tube on.

I think the John Deere green is about the closest color you can get to the stock VW diesel engine blocks without having a custom color mixed.
Anyone ever notice that the gasser blocks were not green?
Anyway, I like to paint engines black to hide oil leaks!!!

That is nicely modelled, with the CFD, did you simply put the airflow onto the inlet and let it work itself out regarding the passing over the fins or did you stipulate that the air had to flow equally over the fins?
I only ask because if you simply told the system that there was an airflow at the inlet on both then it proves categorically that the fins are required.
