I want to add a PCV to my 292.I bought one for a 302 and installed it in the valve cover and hooked it to the back of my carb,(edlebrock).When I installed it ,it ran like crap and had a vacuum leak.How do I make this work?Will the PCV help with oil leaks?

Hey Nathan;  Edelbrock wants the PVC hooked to the front of the carb.  Rear throws it of, with leaks..  Hope this helps.  God Bless  Eddie

On the Y-block its supposed to be installed in the valley cover at the back.On the correct T-Bird covers there is a baffle underneath so you are only drawing fumes not raw oil.I have never run across anyone who has installed one in the rocker cover.There is no baffle underneath and you could be drawing raw oil instead of just fumes.On the 302 or any Ford for that matter where the PCV is in the cover there is a baffle underneath.

  

Thank you ,after connecting it to the front port it seems to work good.I have not driven it yet so I dont know if it will suck any oil up.I do have a few valley pan covers with pcv provision,but they are unusable due to being too beat up.If it sucks oil up I will have to make a baffle.

Nathan - I don't think it should be too detrimental to use your valve cover PCV attachment - the Y's don't usually put a lot of oil in the valve covers. All or nearly all of us run the motors with the covers off when checking out our rocker adjustment, flow out of the shaft end tubes, or etc. It doesn't exactly flood the interior of the rocker space.  If you have a cover with a neat attachment - why not use it?

Ted and others have high horsepower motors that don't appear to have problems with the "atmospheric" style of breather - so its likely that only a small amount of vacuum on the crankcase will do what you want. You may find that the 302 PCV is actually flowing more than you want it to.

As to the down tube breathers. After 500 miles I lifted my car to check the chassis work. Looking towards the rear it didn't seem right, seemed fuzzy actually, especially the differential housing. Went back and looked closer, it was fuzzy, the breather vapored the bottom of the car and caught the fuzz from the glass packs. I was proud of the perfect belly of the car and put the breather down the intake. Waste of time really cause in 12 years no one but me has seen under it's belly.



Hey Martin, take your key and make a scratch under one of your rocker panels so you won't fear getting your perfect paint hurt, I'm half done with breakfast watching you circle the parking lot 5 times looking for the safe spots. Build em to drive em.

Thanx guys .the reason for the pcv was to try and get this engine from leaking .It leaks from everywhere BUT the rear main.I actually tried one from a 300 six and that one seems better.

I started with a 302 Ford and ended up using one off a 80 Zephyr-Fairmaont 4 cylinder.Flowed less-ran better.

  

A pcv valve in the valve cover will very likely pull oil without a baffle. Breathers seem to do fine without baffles. It might help, but don't expect it to fix your leaks. You're probably going to have to replace some gaskets at the minimum to get it to seal completely.

Yeah, gaskets ,gaskets,gaskets....This engine only has maybe 15000 miles.Its just that the oil pan is like 50 years old and the valley cover ,well you get the idea,everything is 50 years old and is beat up.Gasket sealer on both sides of everything.Thing just leaks,but I still love my Y-Block! I will try one from a zephyr and let you know how that goes.I saw one on the Napa auto parts sight for a 64 292,I wonder if that one will work?
