So the other day I got me a set of these
Fab'd valve covers w/o PCV provisions. Got them in the mail last night and test fitted today.
As most mods go, you gotta mod something else to make them work. These are "universal" covers so I was expecting a lil modding.
First off, I took the coils off the oem VC and just threw them on top of the corresponding cover and got this
Not all the holes line up to the studs on the VC...nothing a drill bit cant handle tho
I just elongated the holes on the bracket, some more than others but both brackets needed modding.
The driver side is a VERY tight squeeze because of the main harness but it fits fine...clears the alt bracket and plenty of room against the firewall. My aftermarket wires are long enough to accommodate the taller cover too.
Passenger side tho...this one is a lil different
The dip stick tube is a lil in the way, so I had to bend it towards the AC thingie....the bracket bolted to the head still touches the cover a lil but not a lot. The coil closest to the firewall is literally up against the firewall padding. Im able to get the plug on and off no problem but that fucker is tight. No way these would work on an LS car.
So now that leaves me with the PCV system...The driver side sucks in clean and and the passenger side spits out the dirty air and it gets sucked back into the intake. (Will be adding a catch can later)
Since these covers have no PCV provisions, I gotta get creative. RIght now the plan is to drill and tap the solid aluminum oil cap. I'll have a barbed fitting to hook up the hose from the intake tube
But then that cap is RIGHT above a rocker
So I gotta figure something out to avoid getting oil splashing on that fitting and having it spit oil out into the intake tube. A simple baffle would fix this.
So that leaves me the dirty side to figure out. My initial plan was to buy some fittings and a baffle and hook that up to the original vacuum line. But each fitting is $12, the baffle another $5 and it wouldn't look as nice and theres no promise that I wouldn't be sucking oil out the valve cover. So I decided to run the LS6 valley cover. It has an integrated PCV valve and would make for a simple and clean install. Can get one from BTR for $88 with gasket. SO for roughly $68 more, I can have an OEM look and know itll work.
Nice how to here

All n all Ill be like $200 into this mod. Might not be worth any hp/mpg gains but I like it.
Next up will be Hydroboost and then oil catch can.
