I'm having a problem with an oil leak at the back of the motor. Oil is pooling up on the back of the block. At first I thought it was coming from the take off where my pressure guage is, but i eliminated that. I now think it is the corner of my intake on the drivers side. If your intake is leaking will it leak that much oil? It seems to be the corner where the head and the intake meet at the valley. I used RTV instead of the valley gaskets. I'm stummped, any pointers would be appreciated.

Distributor gasket shot? Leaky valve cover gasket? a Couple other areas to check out

I use the silicone also. You must be careful that you don't push the silicone off the rear of the block when placing the intake in position. I try to set the intake straight down with little or no moving it once it is in place. HTH Mike

My dist gasket and valve cover gaskets are new and don't seem to be leaking. So an intake leaking could leak that much? It's seems like a lot. Thanks for the input fellas, I'm going to pull my intake and try again.

Try using The Right Stuff next time. It works much better than rtv. You can build a taller bead than with rtv, it won't slip nearly as bad as rtv, and there is no cure time.

I use a fat bead of Ultra Copper and let it set up for about 15 min before I set the intake on. Dont use too much though dont want it falling off in the lifter valley. Make sure to add some to the threads of the bolts as well. I usually use Blue RTV for those ones.

What is the right stuff? is that a name brand?

Oh, I see. Permatex the right stuff. So which is better, ultra copper or the right stuff?

You'll get hundreds of opinions on that topic. Its just whatever you prefer. Either one will get it done.

I had a oil leak on my car and i found it to be my driver side valve cover at the rear corner it was hard to find not much space back there.it was leaking between the valve cover and the gasket .what kind of valve covers do you have ?some dont seal good.

Absolutely.:yes: I use Permatex Ultra Black on the end seals and intake bolt threads.

Yes, the back of the intake WILL leak that bad..:yes:

 

[Slick75]

yep

Yeah I pulled my intake last night and found a spot on the back valley where the rtv hadn't cured it was gooey i think it mixed w some assembly fluid during the build, I'll make sure it's cleaner next time and try again. I have proform valve covers. I know my cover gaskets suck I need to get some rubber ones. mineare cork and we've pulled them off and put them on a thousand times.

When you install the intake, be sure to realllllllyyy dry off the front/rear surfaces of the block with brakeklean or the like. If there's any oil on those at all, the RTV will slip right off when the manifold squeezes down. I also do not torque the thing down until waiting for the sealants to cure a bit. That way, the sealant acts more like a gasket instead of a glue.

Good Luck!
