Oil flowing over my serial number
Posted by: macutak ()
Date: September 23, 2017 09:35AM

Hello all. I have sprung a leak. I though it was oil coming it from my alternator mount plate or the gasket. But I just took the fuel pump and alternator pully off Andy tightened all the bolts down and feel I have a good seal with a new gasket an a good layer of gasket seal. After doing all of that, it did not change the rate of flow at all and I now think the oil is pouring out from under my oven roaster. I am thinking it is coming from the oil cooler? I can't think of anywhere else. There is air blowing where the roaster meets the block that ripples the pooled oil there like it is blowing the oil out from under that area. Of course it is making a mess and I would really like to get it fixed if anyone has any ideas.

I aint in it for the money. Just can't figure out what I am in it for.

I am confused by your description of what you did.

Did you remove the alternator adapter and put a new gasket on?

"A good layer of gasket seal"? What type / brand? For me, "too much" equals a problem.

I use a spray gasket adhesive (3M 77) on this gasket.

Oil cooler leaks run "down hill".

Could be a leaking top cover for the crankcase, if the alternator adapter was done correctly.

Could be your top engine cover (blower bearing housing)?

Yes, the alternator adapter gasket is what I replaced. I don't know the brand of gasket sealant but it is red. I followed the instructions meticulously. Even to partial tighten, wait three hours then tighten the rest of the way. The amount of this flow leads me to believe it is not coming from this mount. So I am moving on for other suggestions. The fan bearing squeaks from time to time and I have a new one but have not done it yet. I'll pull the engine cover of and look around for another source. I jus wondered if there is a common area that people were aware of that I could concentrate my attention on.

Fan mount / Crankcase top cover is the normal leakage there... Bolts loosen!

Back in the 1960's I had an Oil Cooler 'cut loose' and blow oil over the top of the engine! I know that sounds strange but I guess it is related to "where" and "what" cuts loose!

This was a leak at the top of the Cooler, not at the In/Out Ports! I discovered it when getting gas and checking the Oil level. Took it straight to the local Chevy dealer and the Shop Manager told me I was lucky to get it there before the engine lost all its oil.

This is not to say the 'usual suspects' mentioned above are not doing it but you should check the Cooler to make sure you don't have a problem there!

Is the oil sending unit leaking?

I get it from oil being blown past the oil fill tube cap. I believe somewhere guidance was provided to put some cardboard behind the cap gasket to force a tighter seal to the tube.

It is not my oil fill cap but thanks because that reminds me to do that to my gas cap that is loose unless I get it just to the right spot.

Yes MattNall, I assume you are
Correct. All will be revealed as soon as I take that off. I will post and let everyone know. Even though it was not the culprit,I did havliose bolt on the alternator mount and one ok fell off the fan belt pulley tensioner. So this little process is not a waster of time. Going 80 loosens up the bolts pretty quick. I have been putting blue lock tire on as I have been doing my elimination process for any bolts that had loosened up. If it does turn out to be my bearing /crankcase cover, do people typically recommend blue picture on those bolts or are heir varying opinions?

I say it is either the black plastic part of the oil pressure sending unit
is cracked or pressurized oil is being blown past the gasket on the oil fill
cap. Replace them both, cheap fix.

Haven't used Loctite on any bolts on a Corvair engine.

I can state the technique that my Corvair mechanic from the 70's / 80's used on the top cover - with good results.

Use 3M 77 gasket adhesive on all sides of the gaskets.

Put a flat washer and a lock washer on the bolts - torque to 11 ft lbs.

I removed everything in thing that the oil is coming from my gasket at generator plate mount versus the fan/ bearing cover. Something I did made the gasket disintegrate even with the use of the red gasket seal. Man I don't want to have to do this again. Any suggestions? I ordered new gasket.

Use Gasgacinch or Permtex 301 on gasket. Leave silicone to the Dr's for enhancements.

I just use SylGlyde grease on the generator mount and top cover gaskets. It's more about getting them off the next time than sealing. Regular grease would do the same thing but I have a love affair with SylGlyde. I use it on heater hoses and gas tank filler hoses. It breaks my heart when a $28 heater hose is stuck on the engine duct.
What you did with the red silicone would allow pieces to break off and clog the oil passages.
I use blue Loctite with the generator mount, top cover and rear housing bolts since they normally only have flat washers. I might skip Loctite if using lock washers. I haven't had trouble getting blue Loctite apart again later, trouble comes sometimes with steel bolts in aluminum for 50 years with nothing on them that have galled in place.
I use black silicone on black rubber valve cover and oil pan gaskets but I put on a thin layer with my finger, not enough to squeeze out and get in the works.
I hate any kind of adhesive on gaskets when trying to scrape it away with a razor blade later.
This is just what I do and I could be wrong.
I hope Dave Motohead doesn't have a fit when he sees the silicone photo.

Use Blue Moly anti-seize to install steel bolts in aluminum. No metals in the compound like other compounds. The combination of metals creates dissimilar metal corrosion and seizes the bolts. Not good for spark plugs due to no conductivity for the ground circuit.


Blue Moly suggested applications: Metal fittings, aircraft components, valves, stainless steel fasteners and slow moving parts, automotive engine bolts and body fasteners, stainless steel flange and pump bolts, chemical processing machinery, gasket dressing, assembly of dissimilar metals

Did you check mating surfaces for warpage?
Did you torque the bolts 7-13 ft/lbs?

I am also having a similar oil leak on my 140 motor. I just resealed my top cover and found the O ring located where the vent tube goes into the top cover to be compromised. Still not sure if that was the issue.

The alternater mount is new. This picture is of the mating surface. It is not the greatest. I see a couple nicks but I did not want to use an abrasive even light weight Emory for fear I would make it uneven.
