Higher compression small block and engine oil is forcing it's way from the dipstick tube and then the engine fan is slinging the oil all throughout the engine compartment. Anything to put on the dipstick tube to stop the leak?....Thanks

Is your PCV valve functioning correctly??? Do you have a breather on the opposite valve cover???

There is a groove at the top of the dipstick does it have an o-ring.

Okay, allow me to back up a little. I stopped the leak from the dipstick by adding breathers to both valve covers, then that stopped the leak from the tube. Now, I have oil coming from the driver's side breather that I installed and it's burning off the driver's side header, etc. The dipstick itself doesn't have an o-ring either. I want to remove both the breathers and somehow cork the dipstick tube also to keep the oil in the engine

Greg, here are some pics. Not sure about the baffle you are referring to, but here is a pic of the driver's side and inside the oil fill, then the pic of the breather that I put in there, then the passenger side breather. Didn't see what it looked like inside the valve cover on the passenger side.

You need a breather in one valve cover and a pcv in the other hooked to the carb. If you don't have excessive blow by then that shoiuld stop the leaks. If you don't let the system breath you will continue to blow oil everywhere. You can't seal the motor up and not expect it not to leak. Remember as the pistons move up and down you have pressure building up in the block. After all the are just big cups underneath.

You do need breathers. One filtered breather on one side and a PCV on the other. Remember that the crankcase has to breath. Between turbulance and piston movement there will always be some pressure formed in the crankcase. No if', ands, or buts about it the this pressure has to be released through breathers or it will make its own way out.

Okay, there is no sheetmetal there, only looking at rocker arms when the breather or oil fill cap is taken off. Here's what I just finished. I just drove the car and got it warm after I put the oil fill cap back on the driver's side, made sure the dipstick was sealed good inside the tube, and then put the passenger side breather back on. It seems to be putting out alot of air (from the breather) as well as light smoke, and I mean really light smoke. Do I have a problem here??? Car runs great. Good torque and power, and doesn't miss or run choppy at all. Oil pressure can be as high as 70-80 when starting off cold, and idles at around 20-25 when warm.

It sounds like you have a fair amount of blowby, but it would be advisable to install a PCV (how many times does a person have to state this?) and recheck the situation. Plumb the PCV to the back of the carb.

Then if the situation improves, install a baffle under the breather and PCV (you dont want or need one under the 710 cap (dont ask).

If the situation DOESN'T improve sounds like worn rings/excessive blowby

Without a baffle you will actually suck the oil splash out of the cover into the carb. Make a baffle.

Thanks for all the help guys. I need to order the pcv. As for the baffle, is it hard to make a baffle for the inner valve cover, or is it just shaping and forming some sheetmetal? And how do I attach it?

PCV system, a rubber gromet in the valve cover with the pcv valve stuck in gromet and a hose to the large vacuum port on the base of the carb. The gromet, the hose, the pcv valve are all avaiable over the counter at the parts store.

I had the same problem as you are having in a 318 I rebuilt once. My engine would blow the dipstick up out of the tube, and also make oil drip out of my breather. Initially, I just had a breather on one valve cover with no PCV valve. I then put a PCV valve on the valve cover opposite of the breather, and my problems persisted. I was confused, because just like your engine, mine ran great, even with all of the oil problems.

I yanked the motor thinking maybe I had a broken ring or that maybe I put on on upside down, or even forgot to put on one...I've seen it done. I got to looking and all of my rings seemed fine, but my hone job looked pretty crappy after I got to looking closer. I had just used one of the the cheapy three-stone hones, and my bores still looked pretty slick. I borrowed a good bead hone, worked on it with that, and re-ringed it...problem solved.

It was frustrating to see that my negligence caused me that much time and money to fix.
