    Question 460 Ford in my jet boat

    Quick question on my new 460 ford jet boat....

    Took it out for the first time to bullhead city last weekend, ran it all the way down to pirates cove and it dripped oil out of the breather (Ford) filter on top of the valve cover. The drip was pretty constant, made a mess and had it smoking. On the right side valve cover I have just a pop in oil cap. I bought it with a mickey mouse dip stick that looks like someone made, so I'm hoping its calibrated correct to the line on the stick and the oil isn't too high. I also have no idea how to determine what size oil pan is in there since the previous owner didn't know. Once I can figure that out I can do a oil change and put the correct amount of oil in it and be able to check the stick.

    My main question is can anyone tell me why its dripping that much oil out of the breather filter on top of the valve cover? I've seen people talking about a " PCV " but I am not familiar with that type.

    Thanks in advance.

    I forgot to snap a picture of mine, but I have the same style filter as this picture, bottom left. looks the same size, pops right into the valve cover.

    You really need to post pics. I have a pcv on my 460 with a breather on the other side. I am in the process of making a puke tank, like in the link you added, because mine will leave oil on the valve cover when making hard pulls.

    I change my breather once a season. I have a pcv on the other side with holley covers. No leaks... my BBF is now a 466 built somewhat to. Leave your dip stick off an put a vacuum plug over the spout. When you need to ck oil take it off then. They leak with the dip in.

    That pick is a little different set up. breather on each side, pcv on starboard hosed to carb and a puke tank set up. Wow. If its a stock 460 start with your gut feeling and find out how much you should really have. Second, what weight oil are you running? Third, whats your oil pressure gauge telling you and fourth if you have an oil temp gauge what is hot temp?
