I asked cause my bilge was covered in it.. However my valve covers are spitting a ton of oil and it drips to the bildge. I pulled the valve covers and the oil sitting there is good and the dipstick looks clear.. Anything else i should check? Odering new valve coevers ASAP... sick of this mess.

Mine was obvious when I pulled the valve covers. Even more so when I pulled the intake. I had the vanilla milkshake all in the bilge as well. Yours sounds like the motor is good though.

Thanks..


Is it required to have vents on your valve covers?

Where is the "ton of oil" from the Valve covers comimg from ? If its the breathers you likely have "blow by" (crankcase pressure issues) Tom

Yep, gotta have atleast one, two is better IMO. Is yours coming from leaking gastkets/warped covers or blowing out through your breather(s)?

Yep, I'm thinkin bout doin one of those with my new valve covers I got..just gotta cut the holes and only wanna do it wanna do it right the first time.

Legally, no, reality, yes.

There is ALWAYS some pressure seepage past your rings, it has to be vented somewhere, or you pressurize the engine, and that WILL blow a gasket someplace, my guess would be a valve cover or an intake manifold corner. possibly an oil pan corner too.

If you have a LOT of oil blowout, you may well have excess blowby which you will find impossible to vent away.

Hopefully your new valve covers are baffled to help catch the oil.

Start with a compression test (dry followed by wetted with a bit of oil), a leakdown test would be even more helpful, looking for poor ring seal.

I have ALWAYS run a PCV, and I feel most people's oil blowby problems that they patch up with 4 breathers or puke tanks, could be cured by the engine sucking it's own pressure out of itself (which is exactly what a PCV does, it lets intake vacuume pull the blowby fumes out of the engine).

Not every item that sprang from an "improve emissions" standpoint back in the late 1960's, was a bad idea, note "open-chamber cylinder heads".

Some people insist on running a vacuume pump to reduce crankcase pressure, so do I I guess, I just use the engine itself, not an extra belt-driven accessory and hoses all over.

There is one hell of a "fog" of oil mist droplets in an engine running at high rpm numbers, oil being sprayed and slung EVERYWHERE, Some of it WILL go up the breathers, the more pressure you have (from excess blowby), the more will get pushed up breathers

I run a PCV on the right side, an un-baffled breather ("mushroom cap" looking, twist-in Mr Gasket chrome special (filled with a fibre material) where I fill with oil) in the left side. My M/T valve covers aren't baffled, but, apparently, I don't have anything positioned right over a rocker squirter either.
I get a little oil that drips on the valve cover, after a year or so of use. Wash out and let the fibre stuff dry, and it "catches" just fine, for about a year.
I consider that a "no problem" level.

Thanks gentleman. I just need to orders some new covers and figure out a good way to sort this out..


I guess a ton is a bit of an exageration but the breather is what is dripping and its running down the valve covers and into the bildge. Yesterday i think it was just more exagerated than other times. Its the first time i blasted thru both tanks with out really stopping...

No oil is leaking from the valve cover gaskets or from any where else just out of that one breater tube.. And its not "bad" per say but a little dribble over three hours really adds up. All in all i think my dip stick showed like a 1/4th of a quart low (if that) after 3 hours of running all over the lake.

I was gonna pull the plugs to check how they were running, ill also check the compression but last time I checked a few weeks ago they were all good. This dribble thing has been an ongoing issue ive just never addressed.



I re read SS answer answer above and i think i just had a epiphany. when i put my new carb on pulled the PCV valve and plugged it up only leaving the other breather.... I think i should put that back on... Don't pull shit off your boat that you dont fully understand . I really can be a dumb ass sometimes.

Lol yea gotta pay attention when u edit a post I still need to get a buffer on mine too. Glad the nordic is turnin out nice devil

1/4 quart of oil in 3 houirs is way to darned much "useage".

WOW!!!.. yea what was in my bildge was nothing like that.. It was just thick nasty water...

you mean like this:

this 475 had only 3hrs on it when i decided to switch pulleys and make some race passes for the 1st with the motor. gave it plenty of time to break in well, lined up to make a pass, flatfoot it, and get bout 700ft in the pass and hear a change in the tone in the motor. looked back and stuff was shooting out my valve covers overboardst the block i used blew a hole in the water passage into the cam gallery. it filled the block with water , ruined a 8k motor
