no, just a rehash of old ones. The oil puddles in the lower half because it can. It can't puddle in the upper half. It's probably coming from the guides, but could be coming from intake gasket, as it sounds like the angles are off a bit. And you never did answer the question about the PCV valve baffle...we know you don't see oil in the pcv valve/tube, but would you please tell us if the valve cover has a factory type baffle in it? or no baffle? or a half ass chinese baffle?
I'll go another route You're not running an open hole carb spacer, correct? The oil isn't necessarily in the lower half of the intake, it's actually in the side of the intake where the oil is entering, because it's entering thru a vacuum hose on the carburetor. And the dual plane design is keeping oil out of half the runners. Note that the other half is completely clean. The other side is yellowed, even on the ridge tops where it's not puddled. Lack of yellowing shows oil is only flowing on half the intake Check every hose on that side of the carb, PCV is a likely suspect. If you're getting oil splashed on the valve due to baffle issues, it'll suck right into the carb. Not an expert here, just a shot.... Good luck
Factory LT-1 covers, baffled. PCV and hose are bone dry. The port for the PCV feeds the middle of the rear of the carb in a manner to dump oil evenly on both sides of the intake. Also, there's an overhang of the carb gasket that would have to get oil on it if from the PCV. No way around that piece of the gasket without putting oil on it. And it's like it never was on a motor. I'm not sure i get the puddling of oil on the lower part of intake because it CAN? Then why CAN'T it puddle on the upper level? They're both flat areas with the same vacuum signal, and the same "washing" affect from incoming fuel. Besides, where's the SOURCE of the oil? Guides? Not likeley. I've had motors with guides so wiped out, it looked like a smoke screen on fire up, and when you'd rev the motor, you'd swear the timing chain was hitting the timing cover (it was the valves RATTLING in their guides) and nothing in the intake like this. Also, bad gasket seal on this 4 months ago, this time, perfect. It's a weird one. But everyone wants to say guides. I got a $1000 says it isn't. The fucked thing is, i don't know what it "IS". But the oil is thickest in the intake leading me to believe it's the source. Away from the area pictured, it gets better, not worse.
Do you have this puddling under your carb? I'll bet no. Your problem i suspect is from the intake gasket area, and DOWN from there, not up like my deal.
oil flows downhill, so it will puddle in the lower half of the intake. The washing probably isn't as effective as you think it might be. There is some reversion in every engine, my wild guess is that it's blowing oil from around the valve stems up into the intake ports and partway into the manifold. then the "washing" cleans out the upper intake tract, but can't prevent or clean out the puddling on the lower tract. There could be a better explanation, but I haven't heard it yet....I guess you haven't either, because you're still asking "why?". Thanks for the answer about the valve covers, those are good ones, I tend to agree that it's probably not from the PCV.
it could be a bad/porous intake. but it could be the guides/seals to, i have had this problem to but didnt think of the guides/seals, now having read theses posts i see how that could happen, when one intake valve is open its pulling a vacuum on the other 3 guides/seals.
REREAD this post. You say oil flows "downhill" (about the puddling on lower tract only on intake), then you think it flowed "uphill" from the valve guides. BUT, let's reiterate on the oil flowing downhill. With this, i agree> If it has flowed downhill as I suspect, and puddled in the lower tract, what now is the source of this oil?
Man, you guys got to get off the valve guide thing. BRAND NEW World products heads. Oil fouled plugs in 500 miles. I suspected guides and put in some real good seals, only to find AFTER, that oil was coming in the intake gaskets. Fixed that, and a different plug fouled 500 miles after THAT. Then found intake gaskets were sealed tight and this new found puddle in the intake. I appreciate the help, i really do. But forget the fucking guides already. 90% have suggested that, and i guarantee it's not. Let's get creative (or not), but i'd be forever in your debt to let the guide thing die. It's distarcting from the real thinking here
List the places it could come from: guides intake gaskets leak in the head (intake ports) leak in the manifold (porosity) pcv system You've ruled out everything...so it isn't leaking oil any more. Either give up, or accept the fact that one of the things you've fixed or ruled out, is the cause of the problem.
ok its not the intake sealing surface, its not a pourous intake, its not valve seals, its not valve guides, its not the PCV, its not a vacuum line. then it doesnt exist someone is dumping oil in from top side, thast it thast the problem. not to sound like a dick but youve shot down everyone logical ideas. yes the heads may be new but they could have a milling issue with the valve guides. installing better seals would have helped the problem but not fixed the problem. i know its not your PCV i know its not a vacuum line i know its not a seal arounf the intake, and the intake isnt pourous. that leaves seals and guides and i have a feeling its not seal. just pull the heads and press bronze guides in it will take an hour and wont coast hardly anything at all.
Ok...i didn't read "Word for word" but skimmed through all the posts. I had a similar problem with my BBC. Most of my issue was the heads were milled and the block was decked - intake was untouched. I know you said that you fixed that issue. totally stupid question - but what bolts are you using for the intake? Is it possible that they are a hair to long and not properly clamping the intake? I know it is totally stupid - but I'm trying to help give ideas....lots of great ideas here. Oh and small blocks have a tendancy to loosen up the center 4 bolts after they've been run a bit (at least in my experience) For what it's worth - I used those "Silicone Inpregnated" intake gaskets before - and have has better luck with the standard Blue Fel-Pro ones with a little Ultra Black around the water jackets on both sides of the gaskets. oh and I realize that it is frustrating and it sucks....I almost lost my motor. I got water into the motor and wiped out all the bearings, cam and lifters on a 500mile BBC.
have ya hered anythin from da edelbrock peoples yet? shit man...you have everthin covered so it must be da intake. prolly got dat dam luminum from jpan er china er sumpin...ya say yer fowlin plugs..how much oil er ya usin in say 500 ta a 1000 miles? is dis bitch smokin like a cheep whore afta ya boinked er? or no smoke atall?
I will still lay a dollar on the intake being the culprit. any word from Edelbrock? easy way to check it if not... got another intake to throw at it in the mean time? If I were closer, I would let you borrow one just to end the "oil mist magic bullet theory". simply stated fellas...if the oil was coming from a source south of the intake gasket, there simply AIN'T NO FUCKIN WAY it's gonna mingle with the other 3 runners. and I don't fuckin care HOW much vaccum it pulls. I noticed also, that aside from the oil fouled plugs, this thing runs RIGHT. if it were a major leak somewhere, you don't think it would act a bit like the VACCUM LEAK it is? whereas, if it were coming from under the intake, under a vaccum from the p.v.c. it would behave until it got warm enough to pull oil through the open passage? sheesh...It isn't the valves, or the guides. Personally, I think Groucho has an angry garden gnome that pours a quart of oil down the carb when he's not lookin'... or a cracked mass produced intake manifold.
Edelbrock called today and claims the intake's OK. No smoke. Customer, who's fairly eccentric claims 1 qt in 500 miles. BUT, after we all went to Palm Springs for an auction earlier this year, he said NO oil consumption in THAT 300 miles. That was right after i found the intake gaskets WERE the problem. Resealed the intake (successfully) and here i am
That's my thoughts. Some of these guys have missed some of the info posted here. BTW, did you see the picture Lux? PS- funny, i was just using the north/south thing with my friend/machinest of 30 yrs an hour ago!
I'm willing to bet it's in the intake, and it's a substancial flaw because the volume left behind is so great. A smaller leak would probably have the bulk of it washed away with the incoming fuel and air charge. However is it possible that the head on one side isn't draining back properly, and is flooding enough to get by all of the usual seals?
well sheit man...ifn dat damn intake is good...wtf ya think now? try nuther intake...den see whutsup wif it. if all good...all good...ifn it aint...then ya just migh wanna do a teardown and inspekt er all. ya aint willin ta xcept guides...so try ring seal. ya ya ya got not much bleed down...but dats about da only udder fuggin thin it kin bee. beter yet...shitcan da friggin pizzashit and build'em a goodin.
Only 1200 miles on fresh (with good parts) SBC (no sludge buildup in oil return passages). I gotta say, it's got me baffled. I consider myself a reasonable mechanic, who understands theory pretty well, and have used the same machinest (very successfully) for over 30 yrs. The guy ran Ray's engine rebuilding (Ray Ackerly of Ackerly and Childs) when i was a kid and i've been using him since. It's a LOT of oil to have not a single trace on the other plenum floor. These guys keep jumping to valve guides. It's not. Ya just gotta believe it. Guides, rings, reversion? All in one half the intake? The intake is the highest amount of oil? And diminishes as it nears those very guides most of you suspect? Come on guys
have ya tried floggin da sheeit otta it? take dat beeitch out and beat it like a rented mule...run dat bitch so tight she wants ta puke...and them drive her some ta see ifn any change...ya just might have a cupla rings dat arent seatin. ya ya ya...da bleed down thingy...i no...but wut else is der?
Over thirty years ago I saw a newly rebuilt small block with a similar problem, it turned out to be damaged or mis-installed cam bearings???????
HOLY SHEEP SHIT BATMAN....ER GROUCHO...I JUST THOUGHT OF SUMPIN.... does dis damn thing have'n oil bath air filter on it? dat damn oilbath airfilter could be seapin some oil inta the damn carb and puddlin up in da intake.....and it is only seepin on one side dats why she's only puddlin up and dirty'n up da one side of da intake!! Sheit man YER WELCOME!!
