B20, with gsr head. skunk2 im with short ram intake. Rest of motor is stock.
Car started leaking oil awhile ago which I traced to the cam seals, so I replaced them with new oem seals along with new belts and tensioners since I had everything apart.
As soon as I started the car and was checking for leaks I noticed the cam seals were leaking heavily, so I shut it off and I could hear air coming out from behind the cam gears, and saw oil and bubbles coming from the cam seals.

What would cause this excessive pressure? Would adding a catch can relieve the pressure? vented valve cover?

 

Its either you're not positioning them right or you have excessive pressure. I had the same setup before but didnt have any issue. My current Gsr is vented with my custom fab of the Endyn catch can setup. The b20 has no crankcase ventilation so adding one would be your best route.

 

i have them right up against the cam caps straight up and down, never had a problem before. The motor ran fine before, but what would cause the excessive pressure now?

I'm gonna try a catch can if the leakdown test shows the head and block is intact and not getting any blowby or losing compression.

Thanks for you help and lmk if you think of anything else.

 

do you have any PCV system at all? where does the breather hose off the top of the valve cover go to?

 

I don't think those are excessive pressure..you might just have installed them poorly.

 

If you've done them before and had no issue then it is excessive pressure. You're motor needs to breathe. Adding a breather/catch can will help the motor breathe. Search and you will find.

 

i think thats your VTECH trying to escape again
are your cams warped at all?

 

The pressure that builds up in your crankcase from the rotating assembly......rotating, needs somewhere to go. This is what the pcv system does on oem motors assisted by the vacuum created by the intake charge. If you don't have some sort of ventilation sytem, that pressure is going to take the path of least resistance....usually the oil pan gasket, valve cover gasket, or in your case, cam seals. In your case the pressure is travelling up your oil return orifices in the block/head and entering the valvetrain area where it has found that your cam seals are the path of least resistance.

 

the only vent was from the valve cover to the intake. I thank you all for your help, I have searched and I guess for awhile i got lucky that it did'nt blow those other seals, the motor ran great for a couple years until the oil leak. I'll add a catch can setup now as soon as i gather the parts and get new seals.

And the vtec didn't escape since there's no oil to activate it, and the cams are not warped

 

How does Vtec escape?

 

It chisels through a wall at night while the guards are sleeping. The hole is then covered by poster during the day.Eventually after years and years, well you know the rest....

 

lol
VTAK gotz pressures and ****.

you gotta punch the valve cover once in a while to keep it down and show it whos the boss. otherwise it will try to escape.

 

VTEC reacts with blinker fluid, and evaporates or deteriorates cam seals... can't mix the 2 inside the turbo encabulator... which is a common failure point on hondas...

 

LOL

 

lmao what a thread
