A/N PCV TO INTAKE MANIFOLD HOSE KITS (drilling into intake required SEE BELOW for procedure)

In determining if you need a 45 or 90 degree kit is how close the PCV is to the port in the manifold. Typically, if the space is less than 5" then a 90 degree kit may be needed. If the manifold is a dual plane intake, a "carburetor" hose hit may be desired instead

The above hose kit comes with genuine hi-quality Aircraft stainless steel hoses and aluminum fittings. The best quality product possible!

You can either drill your intake for a separate isolated PCV source (single plane intakes), plumb the PCV line into the existing hose nipple on the rear of most carbs, or into a spacer plate with a nipple or drilling & tapping it.

Select a location in the intake plenum to plumb your vacuum source to. Since the PCV is basically a controlled, perpetual vacuum leak, you must allow it to pull vacuum evenly from all cylinders. If the location bleeds vacuum from only one cylinder (typical of plumbing it into a single port runner) or from one bank of cylinders (typical of plumbing from one side of a dual plane intake), those affected cylinders will lean out compared to the others and potentially cause severe engine damage.

You do not want to "T" into the source going to your power brakes. The perpetual vacuum leak associated with the PCV system will diminish the vacuum supply and intensity to the brake diaphragm, thus reducing your power brake performance. Since power brakes generally do not rob vacuum under power, it is relatively safe to plumb the brakes from a single port on the intake, unlike the PCV demands.

If you have a dual plane intake, you must make sure the PCV supply pulls from all cylinders evenly, such as from the nipple found at the back of most carburetors, or from a nipple in a carb spacer, which you can drill into it it's 1" or thicker. If you have a single plane intake, selecting a location in the open plenum just under the carb is ideal. Select a location (either front, back or sides) that will allow linkages to clear as well as allow the fitting itself to be screwed into the intake without interference. Mark this location with a center punch.

Now, remove the carb from the intake manifold. Then tear off single pieces of VIVA® brand paper toweling (it is the "clothiest"), and ball them up individually and place one into each port runner of the intake. Then take a flat sheet and lay it down on the plenum floor like a carpet. Now place another couple balls of toweling in the plenum, but with a heavy grease coating the top of these balls. Finally, take duct tape and tape the backside of where you are about to drill your hole leaving an "air pocket" in the center for the drill to enter into and not damage the tape. Redundancy is the key to confidently knowing that there is NO way ANY debris will ever pass by all these your lines of cautionary defense in this procedure.

Using the appropriate drill in accordance to the NPT pipe thread tap you will be using, coat the drill bit with grease to catch most of the chips. After drilling, tap the hole with more grease coating the tap as well. Pipe taps control the depth of the fitting by it's tapping depth. Trial and error will achieve perfect results by occasionally test installing the fitting while you are tapping. Do not tap too deep right off.

You can use a vacuum cleaner or light air pressure to remove any surface chips or debris. By first removing the grease coated paper towels, you should get most of it. As you remove more and more layers, if anything slips past, the next layer will surely get it. Once you get to the balls of toweling in each individual port, you can blow out the plenum area with light compressed air then remove the individual balls. Do not forget any paper towing in the intake.

Reinstall the carb and you done! That's it. And as you can surmise just by reading this simple but very effective procedure, you will not have to worry even the least about the fear of drilling your intake while still on the engine. Average time for this procedure is less than 1/2 hour.
