Just wondering who else has this problem. Never does it on the dyno, but after each pass it pukes oil all over.

It's really annoying. From what I hear I'm not the only one who is experiencing this...

Just wondering what you did to fix the problem.

I use to have it routed the way the instructions from Endyn suggest, but then I just went off the valve cover, and it still makes a freakin' mess!

 

yar, mine does that too, my "fix" was to tiewrap a rag around the breather filter...lol

 

You should consider performing a leak down test on your motor

 

Do you have it mounted as high as possible? Also are you using the Endyn fittings?

 

Is this after one pass?

 

Probably oil creeping up the inside of the block under accelration and coming out of the fitting on the drivers side near the alternator.

 

blow by?

 

...Subscribed. I have the exact same problem, and first noticed it when it was on the dyno

I'm with you on the rag solution, I'm doing that right now too but that's kinda ghetto

 

post pic of how you have it setup.

 

mine did this all the time. never on the dyno only when i raced it. i vented the valve cover also and routed it to its own catchcan and it hasnt done it since, even when i tried to get it to.

 

solution.

-16 off the valve cover --> catchcan.

plug the holes on the rear of the block. that was a bad idea from the begining.

So your plugging all the wholes on the back of the block? What if you run one on the back of the block and one on the valve cover?

 

This is the first ive heard of any problems like this. It would be nice to just run a valvecover setup if it works.

 

Mine filled up, but only after some time on a high comp n/a setup.

yea, that i what im going to do. on the 820 hp car in my sig. we still have one catch can with a -12 hooked into the back of the block, and the -16 coming off the front of the valve cover.

the catch can which goes to the rear of the block always gets oil. the catch can going to the head dont get ****.

i have a -12 on my 450hp street civic,hooked to the rear of the block, the catch can gets filled after like 10 good pull's. the whole bottom of my car is oil cause of this ****.

i believe part of the reason behind this is simply because of the foward momentum. all the oil is going to get slung against the rear of the engine, and it easily finds it way to the catch can. making the front of the engine the only logical spot to put a vent hole. + our factory valve covers already have somewhat of a baffle built into them.

 

Dave, are you using the anti-siphon fittings or conventional fittings on your street car? I haven't had any problems with my setup yet. Endyn catch can set up per their instructions. I set mine up to drain back, so maybe that helps?

 

ive got mine set up the way it should be for a year now and its never filled up after a day with 40 dyno pulls and alot of passes at the track..... i do also wrap a rag around it when im at the track just so i dont get blamed for oilling down the track if it were to overflow

 

Only time I've had one fill up was on a seriously hurt motor at the track on the day of its death. I've probably run that setup on 10-15 cars, tubro and NA, and that was the only one that puked.

 

could it be the smaller ports? my z10 never does this . it uses -12 lines. the endyn uses -8 if i remember?

 

I can't take picture of it right now because I pulled the head off today to replace the headgasket... A blown headgasket didn't cause this because it's done it before. Like I said it doesn't do it on the dyno only after a pass.

I use to have it routed to the back of the block per the endyn instructions, and draining back, and it puked all over.

Also someone mentioned how I have it mounted. It's mounted as high as it possibly can so I don't believe that to be the issue.

I thought that maybe venting it from the valve cover only would cure this, but it still does it. I've heard from a couple who setup a 2nd catch can setup and don't have a problem any more.

So I'm thinking one venting from the back of the block, and one venting from the valve cover.

 

Rob from Z10 told me before that used only one hole from the block(tranny side) and one from the valve cover, I never had a problem on my old hatch making 450whp, I bought a Z10 breather kit again for my current project.

no, these are the Z10 fittings. it includes the plug for the black box hole, and a threaded fitting for the spot just above the black box hole. i do not have the drain back hooked up. if it were hooked up, the can would never fill..... well. it would fill but, then it could drain back. making it "maintence free"

i was thinkin of drilling and tapping the plug, with maybe a 1/4 or 3/8 pipe thread.

 

what is your piston to wall clearance? how much ring gap did you leave? If you built the engine 'lose' it may just be the extra blow by. I had mine setup per endyn instructions and never had the problem on my old stock sleeve setup or the new ERL deckplate 2 setup. are your lines as short as they can be and still be angled downward?

I have my can mounted on the shock tower, where do you have yours mounted? my drain-back goes into the passenger side port.

 

Thats an awful lot of blowby...
I heard the tighter bearing clearances, the more blowby.

bearing clearance has little to do with blowby into the cylinder , i think you mean ring gap or piston to wall clearance.
