So I'm guessing this would be easily fixed by replacing these grommets, but what would cause enough pressure to actually force oil out this way?? I've probably owned around a dozen hondas and have never seen anything quite like this.

Any ideas?

 

It's called crankcase pressure. Change the grommets and seals.

 

that's what i figured...would a oil catch can prevent this?

 

what i ment by that is does a catch can relieve some pressure in the head?

 

I run one of these.

^^Never saw that before. I will have to look into it.

 

He's the only one that makes those.

 

Put some Honda bond on the bottom of the gasket... It how many years old...

 

Wouldn't hurt to change your pcv valve just in case it's not venting properly.

 

Yea, I looked into it last night, but couldn't find anything anywhere. I appreciate it!

 

BTW. It does work. All the previous speculation about them in other threads aside.

 

^ if it were cheaper I'd buy one too for myself...I have the valve cover breather connected to a hose down to the ground and gutted my stock PCV valve and put a hose on that to the ground...no issues for the 12k miles at 235whp

 

Never seen that before but seems like a good idea ill prob have to order one thanks for sharing that..so do you still run a catch can with this oil cap?

 

I bet you could probably make something like this easier than you think.

 

I don't but TBH never got around to installing one even though I wanted to. Won't have that option after the build.

 

Would you recommend still running a catch can if I were to order that?I have a boosted b18c5 .63 10psi

 

I also wont be running stock pcv system or black box will have it blocked off

 

I plan on it. Can't have too much ventilation. I'm removing the PCV system and routing it into the catch can.

 

Ok thanks for your input and the link

 

Catch can if you want to save the environment, open line to the ground if you're gangster

Black box just catches the vapors and drains it back to your oil, I gutted my PCV valve and kept the black box. Some people weld AN fittings on the valve cover and run those to a catch can for further ventilation.

 

I know all of that I was asking his personal opinion when it came to how well that oil cap would ventilate the system

 

You know all that? Then why would you block off the black box? It's just another place to vent your crankcase...

 

Going to be running one of these

and one of these

to eliminate the whole PCV/blackbox system.

 

After seeing that the ebay auction is no longer active, I decided to message the seller. He said that they have been discontinued at this time.

I should have a spare oil cap laying around. I might drill it out and cut up an old, eBay intake filter to see what I can do. Probably won't look as nice, but I'll give it a shot I guess!

 

It could be a lot of things. As everyone said Start with replacing the PCV Valve if you’re still having the pressure I would suspect rings at well the pressure could be from blow by from worn rings as well. I like running catch cans all on my motors boosted or NA it just keeps all that nasty oil and crankcase gases from being introduced back into the motor.
