Well, it looks like my LT4 valve covers are leaking oil from the made4you looms. I think the reason the oil is leaking from the tops of the looms is because the hex's bolts shaft isnt as thick as the stock LT4 valve cover bolts. Anyone else experience this problem and how did you fix it?

 

I know this doesn't help you but I ditch the OTVC set up when I got Corvette valve covers. I went with side mouting instead because of that reason. The stock valve cover bolts were just too skinny.

With the way the LT4 hold down bolts seal with the covers, it would be difficult to get them to work with any bracket attached to them.

If the bolts had some studs attached to the top of them, that would probably work fine.

 

Where can I buy those valve covers at?

 

Couldn't you just use the stock bolts from your old valve covers and put a washer in between the bolt head and the cover (maybe even rubber coat it) to stop the leaking? I just ordered OTVC wires (top mount) and LT4 valve covers and was wondering if this would work?

Or you could do this:

The stock bolts wont work with the LT4 covers. The LT4 covers uses Studs and small bolts on the cover. Below are picutres of parts I ordered and the setup I have now. However, the washer under neither the loom might work but im thinking about using a soft rubber washer under the loom to help it seal better.
