No just slowed down!

 

That's how my TTR manifold was tapped - should be fine!

 

Under instead of over? Why not, it is a science project.

 

The potential downsides to locating the port under the manifold, that I can think of, are -
1. It may be very difficult to get to if you need to.
2. The oil could puddle in the low point of the line, possibly clogging the line.

 

I agree RJ, it seems power mizer got lucky and cleared the fuel rail some how. I wouldn't want the headache of trying to reach it either. Hopefully he won't need to often.

Finally got everything laid out to start building my catch cans. These are a modular, 3 chamber design. Dirty tank, filtering chamber, and fresh air chamber. Made from quality 6061 aluminum and Stainless steel guts. Sorry I don't have a better drawing, I'll keep updated with the progress. Should have enough material for 6 cans or so.



Dirty air enters and goes straight through a SS tube into the dirty tank. Exits through a sintered filter and must work its way out through the filter chamber before it can exit as clean air. With a built in pcv check (hopefully, in theory...)



Here's how the material started. 6' each of 6061 aluminum, 2" square tube and 2" flat stock. SS wire mesh with .015" and .050" openings. To separate those I'll be using the large sheet of poly filtering material. The filtering chamber is made up of layers of poly and SS mesh.



Here's the rough cut, basic shape. 6" tall, Dirty tank and fresh air chamber are 2"T, filtering chamber is 1"T. There's a 1" overhang on the lid for mounting purposes.

The wife's SS is finally coming back together and I'll need a pair of these to get it running again. There's also a local SS owner who would like to try them out. Hope to be "finished" sometime next week. Lot of machining yet to do.

 

Gotta love McMaster Carr

 

I reached the miles for the end of phase 2 testing, with unexpected results.

I only caught about 1 oz. However, it looks like oil was blowing out the oil filler cap also(yeah, I know, not good). I see 2 potential causes:
1. Port 2 just isn't able to evacuate the crankcase pressure.
2. The hose between the brake booster line and the Tee between the catch can and turbo may have worked loose at said Tee. See pic, blue arrow.



When I moved the hose for access to remove the cap on the new intake port, the hose popped right off the Tee. There is no evidence of oil leaking at that spot, but it would have been a vacuum leak, not necessarily an oil leak. I know, that's clean side anyway, but there was mixed liquids there inside the Tee, so my catch can is allowing some vapors by the filtration media(that's a battle for another day).

It's a poor connection to the Tee, I'm going to rework it with a different Tee.

So the (possibly)loose hose may have leaked enough vacuum that the crankcase pressure could not evacuate very well, or port 2 can't evacuate on it's own. I may repeat phase 2 at another time, but now it's on to phase 3.

 

I couldn't find a tee that was 5/16" barb on the run and 1/2" barb at the tee, so I had to make one. Thankfully, I had a 1/4" MNPT x 1/2" barb, and a 1/4" MNPT x 5/16" barb left over from my small catch cans. I also had (2) $5 coupons for ACE hardware, so I got what I needed for under $2. Here it is assembled.



Installed it in about 2 minutes, so I should be good to go now!

 

OK so phase 2 and 3 are both a bust. I'm still blowing oil out through the oil filler cap, so 1 vapor draw point is simply not enough to evacuate the crankcase pressure!

I'm going to have to tee the 2 original vapor draw points together, like drummerboy0088 has done, and start testing again.

 

Forgot Offenhauser?
