Technical Oil spray on pass side..SBC

Need some advice: Changed fuel pump gasket plate,used a one piece Felpro oil pan gasket (but used a little RTV to hold it in place) also the 2 threaded holes in front of block are sealed with bolts & sealer, balancer is dry. Is this engine building up pressure? Oil is spraying on motor mount,frame,burning on header,etc... I am using older M/T valve covers,pcv on driver side,2 breathers on opposite side..........this problem is getting old already,tired of working on it......I went as far as buying another oil pan and Felpro one piece to put back on it,thought my pan may be warped. Some say I need baffles in the covers but I thought 2 breathers would be enough. Please help!!!!!!!!!!

 

If you have two breathers that do not have baffles in the valve cover, then it's likely that it's blowing oil out of them. Quick check...swap the valve covers side to side, see if the problem follows the breathers.

 

Also:

I had a messy leak only at road RPMs, that was found to be the timing cover about 3 inches up from pan. There is a lot of oil slinging in there.

Clean everything with soap/powerwash if you have. Get it all dry from that shiny oil slime, then take it for a buzz.

The problem is the M/T valve covers. The holes are right on top of the rockers instead of in between two pairs of rockers. The rockers basically sling the oil right into the breathers and PCV and there is no room to install a baffle. This problem is even worse if you are using roller rockers. I ran some of these a while back and after discovering the issue and swapping on a different set of valve covers problem solved.

 

I had stock valve covers on it when I bought the car.........never had that problem. Sounds like an ez fix but these M/T valve covers have been around for decades............I'm sure this problem has surfaced before!

 

I fought a similar problem on this thing for a little while, even with stock covers it was blowing oil out the breather cap. I ended up putting a header evac system on this side of the engine, and left the PCV on the other side. Fixed the problem. btw these stock valve covers have also been around for decades, and are a big part of the "look" of this car.

 

Nice work............

 

Is it coming out of the vent hole of the fuel pump?

 

It's coming out low?
Dipstick is what side?

Is there a plug in the p***enger side of the block's dipstick hole?

 

More like "These M/T valve covers have been causing problems for decades" Pull the breathers out with the engine running and watch it sling oil out at IDLE. There is no way a breather can take that kind of abuse, that is why good covers have baffles which these have no room for. I know we like to think of Mickey's stuff as good and vintage stuff a great, but unfortunately are junk no matter how good they look. They would be fine if you had a set that the bosses weren't drilled on an earlier engine that had the pcv in the road draft hole and breather in the fill tube.

 

Do a cylinder leak down test , ( just to see)
All so I have built a longer baffle in valve cover to prevent this, ( oil spray @ breather 's )
What Brand / style valve cover breathers ,
All so I have seen oil lay on top of valve cover gasket ( to big on in side )
Leak out ,
Especially on the adapter for the center bolt valve cover, to traditional
Valve covers, on the mill, I milled out Chanel's along the bottom of adaptors
Inside with drain hole to fix this problem

 

So maybe I should replace the valve covers? Put the stock ones back on.....hopefully these problems will go away!

 

Yes,
I would ,
Diagnostic ,trying different things !!
Hot Rodding takes time to work things out ,

 

X2.

 

No..........put a new pump on it to satisfy myself,old one still good.

 

Let us know when you finally replace the valve covers, if it fixes the oil issue or not.

 

its been a long time simce I've looked at a sbc. don't some small blocks have a threaded port to install a bolt to hold the pump push rod in place for fp replacement? could be leaking from there?

 

I think he answered that question already.

 

I ordered new stock covers for my Vette last night........I'll be selling the M/T covers in a few weeks............I'm really pissed I can't use them, they really are in nice shape and still have the reverse Chevy emblem that was never knocked out!

 

Why sell , sove the Prolbem first, then go from there ,
I have used that Valve cover with no Prolblems,

Racing /Hot Rod / street Rod , it's not always a bolt on and DONE & GO!!!
I have to change my Valve springs every 4 to 6 mounths, on my Hot Rod

 

Bought a new pan, fel-pro 1 piece and taking all precautions puttin' this dog on, sure wish the motor was out........easier to put the pan on! THEN I'm puttin' on the stock valve covers...........it HAS TO WORK!

 

Hope it works for you.
SBC in a truck I just bought. Oil spray coming from same area. I thought it was the timing cover seal for the balancer. Nope! The timing chain is so loose, it has been wearing against the cover. Worn a hole right thru it! Simple job, but a pain in the *** to do. Damn those nylon cam gears...

 

I hate working without a lift!

 

Vette, change pan, engine in the car, yeah good times. At least it isn't snowing! Use some good ramps at least.

 

Idk, maybe the word spray is not the word you wanted to use.
I've never seen oil spray out of a valve cover, nor have I ever seen a valve cover leak or spray on a motor mount. The leak could be traced back above the engine mount trickling up/ down the block and it would be zero wonderment where the leak is coming from.
The fan can blow oil, but the leak is then traced back in a pattern that's Up and forward since the drips would go down and back - again zero wonderment where the leak is coming from. Just because it hidden from plain site or doesn't bit bite you on the *** doesn't mean it can't be found.

 

If it is the pan on the vet in your avatar that has to be one of easiest to do in a car.

 

================

I'd wash things off and get a better look at where the leak(s) are.

Those fluorescent leak test kits can be pretty helpful. I'd plan on changing the oil shortly thereafter.

 

To diagnose a oil leak, and not guess, you must clean engine off. Then run the engine closely watching and looking for the source of the leak. Find out exactly where it is coming from first.

 

Is it a BB or SB?
