Hey all the return cap is leaking on my amsoil bypass..instead of getting a new one I was thinking about drilling and tap the valve cover. Any thoughts, pro, con? Thanks!

The oil returns awfully slow from the head on the 5.9's.
I would be afraid of too much oil staying up top, possibly causing excess oil to leak past the guides and seals.

Should work. That is similar to the setup I have with my FS2500

Here's the best way to do it:

Why clutter up the engine bay?

What is that through the pan? I am sorry I am on my phone so the resolution is not that good. My only concern is the metal savings in the pan, how do you protect against it?

Ace

No drilling: sharp punch followed by a self-tapping hollow bolt. JB welded in for a permanent, leak-free connection.

You can get them from Frantz.

I don't think it's that slow.... consider how fast you pour 11 qts of oil into it when you do a change.

The Gulf Coast-01 on my 1st Gen flows around 1qt./minute new. That is relatively fast in the bypass oil filter world.

Is there nothing behind the pan to worry about hitting???

You could use one of the knockouts into the oil pan since you don't have twin turbos.

Personally I wouldn't worry about putting it in at the valve cover. Honestly I believe most peoples return is through the oil cap anyway.

Ace

Not in that location.
Why make the hole any bigger than it needs to be?

I think I am going to go with the valve cover...so next dumb follow up question any specific location that would be better than any others? Should I just drill into the filler neck? Thanks folks!

mine is in the drivers side of the valve cover
