Blue Thunder 272, 292, 312 Ford Ultimate Ventilation Y-Block Valley Cover

Description

Presenting the new Ultimate Filtration Ford Y block 272, 292, 312 valley cover manufactured by Blue Thunder. This plate comes with the oil fill hole machined and 5” oil fill tube (longer tubes available upon request). In the back of the plate you’ll find a PCV grommet with built-in mesh filtration tube that is designed to pull crank case ventilation from engine without sucking oil, so you can run a PCV valve in place of the provided 90 degree fitting if so desired. This plate has been shot pinned with stainless steel for a magnificent finish that will not rust and easy to clean (unlike other manufactures that still use iron shot on there aluminum that causes discoloration and rusting).
In working with the manufacturer on this cover it became clear that they were not looking to just make a valley cover for the sake of making a valley cover. Blue Thunder has a genuine interest in producing quality parts for the 312 engine family that brings them up-to-date and extends the life of the Y block family. This valley cover helps ventilate the crankcase better than any other 312 valley cover we can find on the market. I’m also pleased to announce that this is one of many projects for the 312 family coming out of Blue Thunder in 2021, that will be a “game changer”!
Please note:
For shipping purposes the press fit oil fill tube is not installed. We suggest using a slight amount of oil on the receiving end, and installing tube prior to installing valley cover on engine. Place the valley cover on a flat surface and wedge against a piece of wood, then place a flat piece of metal across end of oil fill tube and carefully hammer into place until oil fill tube is completely installed. We only charge to do this operation in our facility, however we believe it is a value to receive and determine if the 5” oil fill tube is ideal in your application, or you would like to use a tube that’s shorter or longer. Also know if we install this tube it will change the shipping cost dramatically, as it will change the volume of the package it’s shipped in.
This valley cover will work on the dual quad application, if manifolds front heat core plug is ground flat in conjunction with the surface of the casting. Needless to say other factors will cause variation in fitment including how much a cylinder head has been decked and or intake manifold. However a small amount of fly-cutting on the cylinder head should not be cause for any significant modification to the manifold outside of the front core heat plug being ground flat in conjunction with the surface of the manifold.
_________________________________________
The process of installing the plate is relatively straightforward:
Step 1: Having cleaned off old gasket and excess oil, check for fitment. You will need to install at an angle, slipping under one cylinder head then other. We implore you to try different ways before grinding (sometimes one cylinder head has excessive material under intake port as the other cylinder head won’t, simply installing from one side vs. the other can make a world of difference).
Step 2: If any point of obstructing are identified use a file or grinding tool to to accommodate excessive iron under cylinder head ports. If for some reason your cylinder heads have so much material underneath the ports that grinding would turn into a large project, we suggest taking off one cylinder head versus doing massive amounts of grinding.
Step 3: On a flat surface using a high-grade RTV sealant, place a generous bead of your chosen RTV on aluminum valley cover; then put your gasket in place making sure gasket lines-up with valley cover. Find one or two items that weight a total of 5 pounds or so and place on valley cover until RTV has cured. If you’ve used so much RTV that it’s bleeding out the sides, simply wait until RTV has dried to cut off excess (if you try cleaning it off sealant while it’s still in liquid state you run the risk of making a mess, so we simply suggest waiting for it to cure and cutting excess).
Step 4: Install, you may find yourself cutting off excess gasket material for ease of installation. Make sure to install gingerly, as you do not want to separate the gasket from the plate during installation.
