The greasy intake thread.

[musclemerc]

I recently added an upper intake spacer to my MM and while doing the work it was hard to ignor the grease that coated the entire upper and lower intake, so I figured a fix would be my next mod. I started with a JLT pre filter but it only fits on the drivers side VC and the oil is comming in from the passenger side where the PCV is located, so this is a good piece but not the fix for the oil getting into the upper intake on a MM. So while I had the pre filter open something cought my eye. The element was from a 79~93 mustang 5.0 PCV system and I thought Hmmm that's all to it! So anyway I went fishing for ideas and a catch can did seem like a good idea, but it won't do anything for oil vapors getting through, then it hit me. Do a catch can and figure a way to incorporate the element from the pre filter. I found a company on ebay that had a catch can that had a removable lid and it was made of billet aluminum for $39.99 shipped. I came up with my plan to get the element into the can and here's what I did. I drilled the inlet of the catch can to get a piece of 1/4" copper tube to fit through then flared the end of it to keep it in place, put a nice 90deg. bend with a tubing bender, then used a 1/4" to 3/8" chrush connector that I cut the 3/8" section off flush at the nut before the threads. I then took a 1" copper cap and drilled a hole in it for the chrush connector to go through and afterwards put the element inside of the 1" cap then soldered a copper strap over it to keep it all in place. The cool thing is I can drain the can without removing the assembly and I can also remove the top and degrease the filter assembly. I even kept the JLT piece on the drivers VC just because it could'nt hurt. I'm sure my intake will thank me in the future after I give it a good degreasing. :beer:

pretty cool, company of catchcan? been looking for one myself

I got my panties in a bunch awile back when all these catch cans were being discussed and ended up getting one with way too small fittings. Would this cause any suffication with the hoses? I don't remember the sizes on mine, but they were way way to small to even bother with. Yours looks really good though! Nice work!!

PM sent Dave... Bob the inlet on my set up is 19mm. I'm using 19/32" hose for a nice tight fit so I won't have to clamp it. Considering this is on the vacum side it should'nt be a problem for me.

I wanted to follow up and make a revision. First, Justbob you were correct. The inside diameter of the fittings were way too small and my hoses were drawing closed under throttle, so instead of scrapping the whole thing I went to the shop and got to work and here's what I came up with. I found some 3/4" outside diameter press to fit connectors and redrilled one existing fitting, capped the fitting next to it (to create more room for clearance), and pressed a 90deg. fitting to the top of the unit.I also reworked the inside tube and baffle with a piece of 5/8" tubing and a cut in half 5/8" compression connector and reused the 1" cap from the first set up. I reinstalled the it and problem fixed. :burnout:

Wow, good engineering.

I still prefer breathers :D

[justbob]

Thats some damn good work Bro! Sorry if I jinxed ya before. Mine were only like 1/2" IIRC, so I never did anything with it. Are you a machinest?

[musclemerc]

No I'm not a machinist Bob. I'm a Home Automation Technician (smart house technology). I just love to tool around in my shop and I've always been a car guy.
