oil cap breather and rear main seal issues

so the consensus is that a oil breather cap with the holes plugged was insufficient and i blew my rear main seal after 2 hard days on a road course. is anyone running 2 catch cans? one for dirty side one for clean.

thinking about buying another catch can or getting the 1le seperator from gm

Sorry just saw your other thread.

On my 4th gen's stroker I use the rx oil cap breather and I run a catch can from the Ls2/3 valley cover nipple and instead of plugging it to the intake I run a small breather I got from autozone and I plugged the nipple on the intake manifold and ive never had a problem and i beat my stuff!! Ill post up a pic in a few if you want.

could you post the picks, i am curious. it happened after two days at fontanas road course...i pushed it as hard as my car could go with simple bolt ons with everything else stock. i have since upgraded cam and heads and tune. seal is replaced and good to go so no worries about that...i only wish it was something that failed that i could upgrade hahaha

at fontanas roval i also discovered that i need a better oil cooler...looking at getting one from a zo6 or zr1 retro fitted on my camaro i think.

guess it depends on the price, if its comparable i will use another catch can from a trusted third party i already have the dirty side tackled and it works great!

Hope this help bud.

This is how it looks...


Here you can see the rx valve cover/oil cap breather.
The hose from the valley cover to the CC.
The nipple that's plugged on the intake manifold behind the throttle cable (black)
The passenger valve cover is plugged.
In essence I eliminated the PCV.

Also some have complained about oil in the engine bay but mine has been dry! Never had an oil residue issue EVER, and I'm a near freak when it comes to engine compartments lol.

Not sure if it's applicable, or would help with this particular issue, but saw tips/photos a while back about enlarging the hole in the driver's side valve cover....

No need really, with the valley and passenger side vc with breathers crankcase pressures should be ok.

Only other time I heard of a rear main seal going out was from the catch-can hoses being connected incorrectly (backwards)...just sayin'...

Venting the can defeats all crankcase evacuation. The only reason you build up pressure is the fixed orfice is to restrictive and if using the breather there is no place for the pressure to go if you build excess as it has a oneway checkvalve in it to be emmissions compliant.

Here is the thread explaining the mod.
http://www.camaro5.com/forums/showthread.php?t=239961

If you just vent, then you leave all damaging combustion byproducts in the crankcase. They need to be evacuated while still in a suspended state or each cool cycle after shutdown they condense into the oil and that results in shortened engine life.

GTO LS2 guys used a vented pressure relief oil filler cap if the crank pressure exceeded 10 kPa (110 kPa absolute) There was a service bulletin on it if the PCV system got frozen or blocked. Part # is 12589430 and they are around $10. Same cap as my kid's Monte Carlo. Cheap insurance to keep from blowing out a seal IMO. It's a one way valve so fuel trims are not affected. No air is sucked in, only vented on elevated crankcase pressure.

so the Rx check valve oil cap breather is the way to go or the ecs style breather that's just open in the cap?

The oilcap breather is a one way out only that i have installed. I have the Ls2/3 cover and that is already a one way iirc. I've had that on my Ls1 and as far as I know still running strong on another fbody with the same setup as mine.

My RX breather is one way in. It lets nothing out.

i wont say who's product it is because it wasn't a product issue...I am pleased with other products of theirs...in fact I am thinking about buying more from them if that shows how much I like their work. This paticular item just did not work for me when I pushed my car to its very limits.

It was an issue with to much pressure not being able to be relieved out of the block...everything fixed no damage but to the rear main seal...new seal no problems. I need a way to relieve pressure as well apparently with how I am driving it in a very specific scenario...ie road course with long periods of wide open throttle.

I did not get time to go to a dealership and shop the price for the 1le seperator. but i will soon.

I bought a RX breather...I have a feeling I should yank out the check valve so it would work like a ecs style. Ecs was out of stock when I ordered or I would have just bought that one. I'm at 10psi and I am just wanting a place for extra pressure to release under boost if need be. I have an elite catch can going on the line going into the intake manifold on passenger side, right before check valve that came with vortech kit. All other Pcv connections are hooked up as instructed with the kit. I don't give a flip about emissions.

Won't You have unmeasured air then if you remove the checkvalve? It only lets air out.

Unmeasured air doesn't effect anything. There is no correlation between crankcase air, and measured air, so long as your intake stream doesn't ever see crankcase air.
