Oil Leak Under Back Of Intake
 

When I put the Edelbrock Air Gap intake back on to the Edelbrock aluminum heads, I used new side gaskets and Permatex, black, gasket maker, on the ends. Apparently I did not put enough on the back side. I have a SMALL oil leak, at that point. I'd rather not have to take the manifold off, because it sealed real good on the sides - no leaks there. -- I don't know how much pressure is at the back, to push oil out ?? -- Is there a chance that I can clean that area, real good, with lacquer thinner, and run another bead of Permatex, on the outside - push it in, and smooth it with my fingers, and solve the problem, or at least work as a band aid, for a while ?? -- Yes, I know that the real fix is to take the manifold off and start over. -- Thanks

Yes, same as I have done. If your PCV system is working properly under the manifold should stay in a slight vacuum. The oil showing is due to splash and then seepage not from pressure pushing it out.

I would not try and remove any of the existing bead as you may push some in while trying to remove it, which then creates another problem.

Magoo....... You can try that..... Clean it well with brakleen and use the gray stuff. Make a nice bead and let it dry and see if that works... If not... Well you know what needs to get done...

OIL LEAK
 

-- Yep - I'm hoping that it works. -- I'll get some gray Permatex, as in the Permatex site. -- Keeping my fingers crossed. -- Thanks

The simple fix is always worth a try, you can always do it correctly if it doesn't work.

WORK ??
 

--- I assume that it worked. -- ??

Magoo -

Band-aid at best.
It has little to do with pressure, oil will seep through most opening if given half a chance. Ever have a valve cover leak, even right next to the PVC?

If you want a permanent fix you're going to have to do it over. Have sure both surfaces mate and are clean before applying sealer.

Archer[/QUOTE -- If I force it in, in addition to what is already there, then there should not be an opening. -- Oh well !! -- I'll try it anyway - not like it's a big effort. - I'll take the distributor out and get at it.

Magoo -

Sure it's worth a try ... but if oil was leaking out, that kinda means there's a coating of oil on the walls of the the opening. See the problem ?

Leak
 

-- We'll find out as soon as I get the ambition to deal with it. -- Thanks

Yes it did work Magoo. I think I used alcohol to clean area and dribbled a bit in through leaking area to clean oil off. Used a tooth pick to mush it in the "crack".

Looks like it worked
 

-- Got it done and have driven the car about 200 miles. - No leaks, so far. -- At this point, it has worked.

Glad you got it stopped for now..... :)

HOPING
 

--- Hopefully it's more than for now.
