The 1994-1998 12 Valve Ram diesel uses a crankcase vent on the side of the engine. Because this vent has no catch bottle, oil can drip oil onto your driveway, leaving black oil stains. There was a kit available from Geno's Garage, but it has been discontinued. These are the instructions and the parts list from the Geno's kit.

1 - Summit Racing Catch-all part number SUM-G1504, price $29.99 + shipping and handling (800) 230-3030
3 - ¾” hose clamps
1 - 6’ x ¾” heater hose
1 - 1’ x ¼” vent tube
1 - ¾” x 11/16” brass fitting (12-valve engines)
1 - 1” drill bit (to drill the Summit G-1504 to accept the 3/4” x 1” male barb)
1 - ¾” x 1” male barb (epoxy into the Summit SUM G-1504 bottle)
1 - ¾” x 45-degree turn down (epoxy to the ¾” x 1” male barb)

With the exception of the Summit Racing Catch-all, most parts can be found at your local hardware store. Finding the 45-degree turn down is important as the crankcase vapors did want to come back out of the breather cap on our test model. You can make a cost-effective, non-critical, choice to use off-the-shelf heater hose.

Your Catch-all can be mounted in any vertical location. Because of its 13” overall length, we chose the front, driver’s side of the plastic fender well to mount the Catch-all. Note: Inside the Catchall, the breather fumes are directed 45° downward. Even with the fumes directed downward, experience has proven that the Catchall breather needs to be vertical or oil will collect/seep out of the breather.

• For access to the fender well, we suggest turning the steering wheel all of way to the left.
• Vertically test fit the Catchall to the fender well. The top of the breather should be positioned ½” from the bottom of the back/bottom side of the battery box.
• With a ½” clearance at the top, the drain valve should be barely visible under the bottom of the plastic fender well. As there is a small plastic lip at the bottom of the fender well, you will need to cut it off to allow the Catchall to flush mount to the fender well.
• With the Catchall in its temporary position, mark the fender well and drill two 3/8” holes (the center line distance between the holes is 3 ½”) through the plastic fender well for mounting.
• The existing breather tube is 11/16”, an odd size. The transition from the 11/16” breather tube to the ¾” hose supplied in the kit is done with a brass fitting. Insert the fitting into the ¾” hose first as you will have to push/stretch (a soapy solution will help) the hose to insert the fitting. The fitting should slip easily into the 11/16” breather tube. Tighten the clamps. Test fit and route the ¾” hose to the Catchall assembly. Cut hose to length and press on to the hose barb. Tighten the clamp.
• Install the kit to the fender well with the two 7/16” bolts.
• Important final note: Double check your routing of the ¾” hose to assure there are no kinks in the hose. Kinks to the hose would not allow for engine breathing and could cause seal leakage.

Maintenance Instructions:

Drain the Catchall at every oil change. Oil discharge should be minimal. At every other oil change, we suggest you clean the breather using a Simple Green solution and water. As a precaution against a clogged breather, we left a small ¼” vent tube at the top of the breather.
