Ok, like the title says, I need a oil catch can for my car. As of now my car makes 700hp+ and does not have a catch can installed. Im also still using the oem pcv valve. The problem im currently facing is my oil pan is leaking and Im assuming this is being caused by high levels of cc pressure. If anyone has any suggestions on what to do please let me know.

 

Anyone?

 

There is big thread that covers this.

TSComp started it. Title is something like "for those who have high crankcase pressures"

 

This is what ive been using on my 700+hp evo and has worked like a charm


Buschur Racing Catch Can

http://www.mellonracing.com/indeThe

The entire kit is built from tig welded 304 grade stainless steel.

Included in the kit is a modified, new dipstick. You simply remove your old dipstick, replace it with the new one and run the hose from the bottom of the catch can back into the dipstick. This also acts as another port to relieve crank case pressure. You end up with 3 ports to vent crankcase pressure rather than the 1 factory port. This does free up some horsepower.

This catch can unlike any others on the market has four ports. The top port is the vent. The included breather can be removed and a hose can be attached to the top of the catch can and ran back to your turbo inlet if you wish to do so. This will pull the crankcase vapors out of the can and run them back through the engine. It works quite well. The two side ports are for the inlet hoses from the valve cover. The stock valve cover has one vent on the drivers side and the PCV valve. This is intended to eliminate the PCV but can be run still using it too. If you choose to run the PCV you will simply hook the hose from the valve cover directly to the side port of the catch can and then you can run the top port, with an inline PCV back to the intake manifold. This will allow the PCV to function but will not let the oil get back into the intake manifold.

Last and the most important feature of the can is the 4th port for returning the oil that gets into the catch can back to your oil pan where it belongs.

The can mounts to an existing tab on the firewall and uses an existing bolt to hold it in place. The only fitment issue is with the factory fuel pressure solenoid located on the passenger side of the intake manifold. For anyone running a stand alone it should be eliminated anyway. For those of you with the factory ECU simply unbolt it and leave hooked up so you don't get a CEL.x.php?main_page=product_info&cPath=1_16_22&pro ducts_id=191

Ive always wondered in a street application why the catch can. Is this extra pressure happening because of wrong gaps, etc? Why AMS street cars dont use catch cans? Mine has 15k on the motir and using the stock PCV system. Dipstick doesnt shoot out, no oil leaks. Im wondering, because I recently installed one and did I really needed it?

 

Most common use is for keeping oil out of the intake and intercooler. Oil coats the intercooler and pipes making them less efficient. I use a Kobalt mini air compressor filter on my Altima between the intake manifold and PCV valve and the amount of oil it catches is unreal. Even after 5k miles on the same change of oil, it still catches oil but the intake manifold is spotless now whereas it had oil coating the entire manifold and runners.

 

i just use a buschur catch can, no problems at all.

 

Same here. Iv seen plenty of hi hp cars with no catch can at all. I didn't start having problems until I blew a couple freeze plugs. That's when my oil pan started to leak so im assuming im having a cc pressure problem. Thanks everyone else for the ideas and ill prob just go with the Buschur setup.

 

The weird thing is though Iv never had a problem with my dipstick. Before the pan leaked and I blew a couple freeze plugs I was convinced I didn't need an oil catch can.

 

Go with that thought..never have to drain the catch can either

 

W1n. What a good idea and way easier than going all the way back to the oil pan.

 

Do you use E-85 in your car? Only reason I ask is that in every car I've had that runs E-85, the fuel creates ALOT of condensation that ends up in the catch can. My catch cans are usually filled with an oil/water mixture due to this condensation.

Personally, I don't want watery oil being diverted back into my oil pan.

 

Same here, even on pump gas my can has always had more water than oil. I refuse to have it drain back.

 

^^^that might be something you can ask DB directly. I can't remember seeing a CC on the badbish but i think he runs E98 in it.
