So.. been buzzing around in my coupe now for 5 years or so... mechanically. it runs perfect..... but little issues always arise. I've never owed a Supercharged engine before.. but What i have seems to run very very well. (Watch,... now i have jinxed it!) So, one issue I have had was after a long run,.... Oil would be splashing... or actually misting and leaving a mess on the upper ridge of the VC's.... not a big deal... just messy.On short runs... it really would not have(or I just could see it) but after a 5-8 hour day of driving on the local hi ways,... when I got home..I was wiping Dino Juice. It just started to bother me. The coupe never had a PCV system... not a big deal.. but I just could not bring myself to drilling into pristine Dodge VC's with a big ugly Valve sticking out. Also... the previous way of filling the engine with oil was a major PIA..... was using the oil tube in the valley Pan.. with a rubber bolt in the centre plug.Very difficult to get at due to the blower set up. It needed to change. The old trick was to use a set of Water fills like that on top fuel cars.This has been done countless times in the past on many a Hemi powered car. So I thought about a PCV SYSTEM.... So I had a set of Donovan Water Fills from my ill fated Drag Roadster Project.... I found a tight 90 degree PCV Breather at the local parts store and a grommet that fit snugly into the Water Fill. Running a 3/8 fuel line from the rear second carburetor .... a brass fitting , I ran it under the blower manifold and out to the drivers side under the alternator bracket.I always use fuel injection clamps.... better than those crappy Chinese band clamps. MAKING THE WATER FILL WORK--- my big concern was the bolts I was going to use.... that the head would interfere with the rocker assembly inside the VC. It sure did.... so I ran down to my local machine shop and he turned the heads down"About" 1/8 or 1/16th... not quite sure... but it cleared the rocker assembly just fine... I wanted no pieces touching or getting any wear on the assembly..... vintage engines ain't cheap. I think the hardest and longest part of the process was staring,measuring,staring, measuring,measuring and balancing the Waterfalls to the right angle and height. Of course.. taking a set of perfect valve covers and drilling holes into them made me think...... along time. You have one shot...don't miss. I peppered holes on the oil fill side after use the gasket as a template(ya gotta make your own gaskets) I made one small breather hole(1/4inch)? on the breathe side. I test fit again and everything worked out well..... Got out my"Right Stuff" RTV goop and put it all back together. I waited 24 hours to make sure everything set up properly and torques the VC'S to factory specs. All seems to work well,.. no oil misting, all clean and functioning. I don't have a ton of pics.. but you will get the idea..... I believe this could work well for many types of engines... just got to get creative. So there is my crappy 1 day tech.... Like I mentioned.. been done a million times before, but this was my situation. Now my little Hemi Dodge...suck and blows at the same time..... like my ex wife ha ha
I should mention I used Button head bolts.... You need to find the latest head possible..Elevator bolts would have been perfect.. but making a square seat would been.. impossible at this stage
My oil fill, seems great minds think alike. After I took this pic I did engrave "710" in the lid just to make sure no one poured water in it.
As an observation, a correct PCV system should include “all” of the air in your engine entering the valve in the water elbow. As I see from your photos I’m guessing most is coming from the closest rocker cover breather. The 2 on the same side as the PCvalve should be sealed and the one on the opposite side closest also. Just an opinion on how the systems were designed to work. What you have looks great and I have 2 of those water fills also.
jimmy six..I completely agree with you...and if I had the room at the firewall,.. I would have installed the waterfalls on each end of the VC's..... but.. ya gotta work with what you have. So far..It seems to work very well.
I think you might have missed what Jimmy 6 was telling you,, you need to block the little breathers so your PVC doesn't just grab outside air and circulate it to the carb, but instead you need to removed crank case pressure from the lower end to stop the 'oil spray' in the upper end,,
Just seal up the 2 breathers on the side with the PCV, and the front breather on the other side, so just the rear breather on the opposite side is open to atmosphere. That will have the PCV draw fresh air IN through the back of the opposite valve cover, down through the crankcase and back up to the PCV and out to the intake, fully venting the engine.
I installed a Wagner valve in the Boss engine in my Cyclone, it just ran today for the first time so I it is too early to know if it works. I need to adjust it one more time and put some miles on it, from what I read when I researched the valve it should eliminate any crankcase pressure and I should have no pressure related leaks. It is a high quality piece, very well made.
Jeff, I really like your setup.....very, very slick. Mine's pretty simple, I came off my breather with an inline PCV to the carb. I used a breather screen as a template and cut a plate from sheet metal to plug the top of the breather and epoxied any voids around the edges to seal it off. I stuffed the breather full with a stainless pot scubber for a filter. As others have said, the driver's side breather is unaltered so it's pulling across the engine, grabbing the crankcase pressure.
Thanks for the explanation and pictures @Jeff Norwell, inquiring minds want to know about the toggle switch on the rear carb?
My bad guys.I failed to mention what Joe Blow mentioned.I did fill the PCV water fill full of that Pot Scrubber material as well.. just like whats in an FE PCV basket.
