oil catch can

[rubicon]

Does anyone have experience with using an oil catch can? I do not have a PCV valve on my engine just breathers on both covers. These breathers get saturated with oil after about 100 miles and oil start to hit the firewall. I'm thinking on using an oil catch can but not sure how to hook it up. SBC383 stroker with triple deuce set up.

Do you have baffles in your valve covers ?/

I've had the same problem. I'm adding valve-cover baffles and a proper PCV setup.

oil start to hit the firewall

Its just the sweat of an honest engine at work....

I have baffles in the valve covers and the caps are also baffled with filter. Oil miss still fills up the caps from the crankcase psi. I'm going to use oil catch tank with breather and run hoses from the breather holes in valve covers to the oil catch tank. There, I will vent the psi. Hopefully the tank will catch the oil and the only thing I vent is gases. I just ordered the parts I needed from Jegs. I will make some fittings to go into the breather holes and screw my AN fitting into them. I'll take pictures when I'm down. Let you guys know how it works.

I bet if you install a PCV, your problems will end.

Guys with small high performance boats (500 - 800 hp) been doing that for years. They often run with throttle wide open. They call their tank for catching oil, a puke tank.

I had oil spraying out, at the Fun Run, in Ocala. "Baffled Breathers" solved the problem completely.

Depending on the thickness of your valve cover, you can use:
"Moroso 68775 - Moroso Breather Grommets with Integral Baffles" or
"Moroso 68776 - Moroso Breather Grommets with Integral Baffles".

Sorry, I would have posted pics, but I am traveling. If someone does not add them by the time I get home, I will add the pics.

Pic of the above grommets . . .

I use one on both of my supercharged toys. The first one I made by splicing in a moisture separator on the pcv line. it works. The other I bought from JLT, JLT Oil Separator 3.0 Passenger Side (2007-2014 GT500) [3012P] - $139.00 : JLT PERFORMANCE, Home of the JLT TRUE COLD AIR KIT. It catches a lot of oil that would contaminate the intercooler and put oil in the fuel mix.

Thanks for posting the pic Spanky!!!

Did you do this yet?

I went with Vibrant Performance # 12695. This model has two IN ports. The fittings were 10AN. I change them to 6AN because I already had 6AN hose and hose fittings. I had to add SS scotch brite pads to the inside because I was getting some mist coming out of the catch can breather. So far seems to be working. Only time will tell.The can is mounted on top of my frame and hangs down almost a far as the oil pan. It has a drain plug in the bottom. I looked at the Mishimoto but did not like the idea of unscrewing the can.

 

[choppinczech]

Nice. I've been plumbing with their hoses and fittings. They're well made.

 

[railroad]

I used the same logic, different material in the bottom of my JLT cans. I cut a circle of fuel cell foam about 3/4" thick and put in the bottom of the can. You probably will not have an issue, but Scotchbrite has some very hard abrasives on the fibers. I doubt any will migrate into the engine, but ??? Maybe some stainless steel wool would be safer, if you do not have some cell foam.

 

[2old2fast]

There is no such thing as SS scotch brite ,I'm guessing he meant SS kitchen scrub pads...

 

[roadmonster]

Why not PCV? Or why not PCV + breather? I have PCV on one side, breather on other. Breather never gets wet.

SS scrubbing pads. Scotch Brite is the brand name. Sorry if there was any confusion. If I use a PCV I would have to alter my carb intake and all that gunk would be going into the carb to get burned. I want to avoid that if possible.
