Anyone ever done this, On the underside of the manifold, behind or in front of the heat riser, in one of the intake runners, drill a 27/64 hole, tap it 1/2 x 20, install a Fram FV- 482 or a 277 PCV. If you've done this or heard of it, what were the results ? Email me at liphook@i-zoom.net, ....cheers

why would you want to ruin an intake manifold? tell us what year engine you are working on and someone will tell you how to install a PCV

Had been working on a '36 and a '46 14 yrs ago and got sidetracked, now back at it. Found an email that I got from a V8 club member in 2001 and he had suggested it, looking in index of past V8 Times I see 3 references to the subject however I don't have access to my magazines right now

There was an article published in the V8 Times several years ago that outlined how to install a PCV into the bottom side of the intake manifold.. The article looked very slick, and had some merit if a person wanted to conceal the PCV, however, it was not a very practical idea. The PCV needs to be serviced from time to time, washing it out so the valve therein does not stick.. Having to tear an engine down to get at the PCV for servicing looked like a pretty dumb idea. There are several easy ways to retro fit a flat-head engine with a PCV system.. I'm a firm believer in PCV's, I have installed them on many older engines which did not come equipped with same..

No mention here of the fact a 1936 has only a labyrinth rear seal . Add a normal aggressive PCV system to a labyrinth seal type motor and you will end up sucking cr*p from the bellhousing area into your motor . I do not consider that a good idea .

And on top of that the world is really flat, anyone can see that.. The negative vacuum pressure in an engine is very minimal, it would be near impossible to pull debris through the rear main seal from the bellhousing area. The bellhousing area on a Ford flathead is pretty well a closed area.. Although it might be possible to pull the "fly's" out of the flywheel, or the spiders out of the "spider gears"..

Bellhousing area is pretty well closed ? Ever notice the cotter pin hanging out of the hole in the bottom of the bell area of the oil pan ? How about the vents in the cover in the pic ? An aggressive PCV system will not suck rocks off the road BUT IT WILL pull clutch debris - dust into the oil pan .

Why would anyone put a PCV in the bell housing area? The purpose is to suck fumes out of the crankcase or valve chamber area.

Nobody in their right mind would put a PCV in the bellhousing . The issue is with an aggressive [ manifold vacuum ] PCV system and a labyrinth rear seal you will at times be sucking air in through the rear seal area . Deceleration would be a prime time for this . And comments were made about the bellhousing area being a " pretty well closed area " and that of course is not the case . Heck a 36 tranny doesn't even have a front seal .

It would appear that some of the readers/contributors to this topic are poor readers and/or have the opinion that: "Don't confuse me with facts, I have my mind made up". How someone interpreted the comments that a PCV was to be installed in the bell-housing, the comment (s) that the negative pressure/vacuum would pull the oil out of the transmission via the unsealed front collar,is beyond me. I find it to be very interesting that the topic of PCV systems is currently getting a lot of traction on the Ford Barn Forum, over three pages of comments. I also find it to be very interesting the great lengths that people go to, to conceal a retrofitted PCV system on an engine that is very highly modified. Bill 36 5 win delx cpe
