5.3 valley cover question newb to these ls based engines so i have a question on the gen3 valley cover. I'm adapting small block script valve covers on my setup and wondering what to do for oil fill cap. can i put an oil fill cap in the valley cover? here is a link with a piece I'm looking at so i can keep knock sensors as well.

Will this work for filling oil for the gen3 5.3?

Should be fine... There are several manufacturers making valley plates with oil fills in them now. Shouldn't be an issue.
Funny you posted this now as I'm looking for the same thing but wasn't planning to run the hi-ram the only valve covers I've found that cover the coils AND have an oil fill are the Billet Specialties but they're over $1000 a set.
I want the look but I guess I'll have to relocate the coils to get it done.

Update I found the BS adapters at Summit without their valve covers for $499. Still not cheap but by the time I relocate coil packs and buy new wires and/or buy a valley plate with an oil fill the costs are getting closer.
Other downside....have to pull a valve cover to add oil. Not a huge deal but still....

1936 ls1. i may be able to help you on that. i've done a bunch of research for my setup because it needs to be pretty specific.
try this out see what you think https://www.cfrperformance.com/HZ_80...z-8000-pbk.htm
this was a perfec solution for what i want to do. plan on running script valve covers. i'll probably also make a small notch in the back of the adapter for the coil wires to tuck them back behind the engine so you can't see the wires either.

only bad part i came across is the oil fill issue which is exactly why i started this thread. i wasn't even sure if the 5.3 engines were ok to fill from the valley cover. I've never had one off but looks like it will work out great. and Holley makes weldable bungs with oil caps so i'll probably just save the money. mod my oem cover and powdercoat with everything else when done.
Summit sells a set like that too.

I don't see any reason these couldn't have an oil fill cap added to them just like the Billet Specialties units.

yeah you could really just drill/tap a bigger hole for a cap even just use a hex head bolt. pull the small block cover off, lose no oil or worry about gasket sealing, fill up and back on. maybe i'll just try that instead of the valley cover mod.

on my setup i will drill that barbed fitting hole out for a bigger -10an male fitting then run -10 out the backside of the small block valve cover. probably notch the bottom/back of vc to let the line come out to a breather catch can that will sit behind the engine. i'll run one from each valve cover and another from the valley cover to catch can and not run a pcv style system. that make sense?

With mine being turbocharged and having a catch can, I think I'll end up with a setup similar to what you described.

i like the open breather cans better. We run 4 -10an off of our 1000hp honda valve cover and see less than 2psi of crankcase pressure at 45psi of boost. I figure if it works on those little guys the 5.3 should be good with one off each valve cover and one off valley cover. i don't even know if the valley cover one would be needed but can't hurt.
