On the fence about doing the 6.4 manifold...

[16WhiteQC]

The stock intake is leaking oil on my truck, it has been for a while actually.

I have been back and forth on just doing the 6.4 but there is a good amount of additional cost involved vs just replacing the stock intake.
(new intake, tune, extensions, ETC...)

If I am being honest I am at a place with my truck where I am kinda done modding it. I'm not racing or anything else, and the truck run damns good currently for DD use.
AND
I know I will need to do a cam at some point so I'd rather put the $$ towards a JG .5 cam when the time comes.

So, am I being foolish thinking of sticking with the stock intake and I should do the 6.4 because for the added cost it's worth it/that noticeable of an upgrade on a DD?

Pull your stock intake and replace all the O-rings,especially the ones that surround the pcv port and the oil fill hole,the black ones surrounding those 2 holes are notorious for hardening over time,and leaking oil. I've had good luck using Felpro's O-ring kit for the hemi. The intake bolt torque is 108 in-lbs or roughly 9 ft-lbs,i usually wire wheel the bolts clean then reuse them ,you can use blue locktite on them if you want,but i've found they'll still loosen up over time,even with red locktite,so now i just run them in dry after cleaning,and check the bolts every oil change or 2.

Thanks, it looks like it's leaking at the seam, just below the PCV

Good ole original 2 part JB Weld works wonders as long as you get the surface clean

Updating this:

I decided to stick to the stock 5.7 intake manifold.

All OEM intake manifolds seem to be on back ordered with no ETA so I got my google on.

Found this website and grabbed a dressed 5th gen new take off intake manifold for $630 shipped -- https://custardcoresupply.com/search?q=5.7&options[prefix]=last

Intake came in as expected/shown, the only thing I need to swap is the injectors and rails as the 5th gens are a different part #.

All in all not a bad deal for a new intake, PCV, Servo and TB!


Fingers crossed when I swap the intake my oil leak is actually all from the current manifold and not an MSD solenoid or such under it!

Sweet!

Injectors aren't cheap, I'd imagine you could recoup a bit of your cost between those and the fuel rails.
