Oil Blowby
I am getting some oil blowby from my oil filler tube. Not real bad, but it makes the engine compartment messy. I assume I have the old type filler tube baffles in the tube because I have an early AR engine. Would the improved filler tube with steeper baffles work out better? I have also seen a cap that has a tube attached to vent the smoke / blowing oil under the car. Is this a good remedy? I am not concerned about excessive engine wear as a cause of the problem. Compression is 55 lbs or a little better on each cylinder. Spark plugs are not sooty / oily. My A has plenty of pep and I can climb a rather steep, curvy hill near my house in high gear. My neighbor has an old Chevy truck (6) that won't make the hill in 3rd gear. The cap with the vent tube might work. I just don't like gimmicks. What remedy did the old timer use? Thanks, BW

Re: Oil Blowby
the blow by tube was made for years to help that problem . also was told to use a 'pcv' valve to help , even on the open system ............... steve

Re: Oil Blowby
I have the flexable vent pipe and cap on mine. It works well. In my case it was raw oil droplets that came out of the filler tube and not smoke that messed up the engine compartment. The filler tubes were redesigined and enlarged in 1932 to eleviate the problem.

Re: Oil Blowby
I find that an old sock over the breather tube will keep all the oil confined and the engine compartment clean. And will not cause oil pressure to build up and leak out the rear main seal. I tried the breather tube once and that caused the oil pressure to build up. It should hold you over until you decide to do something with the engine.

Re: Oil Blowby
My relatively fresh engine also will spit a little bit of oil on a long hard run. Even though the quantity is small, it still makes a mess.
bogdonj, thanks for the pictures. Is this an old SOS pad that you used to stick up in the oil filler cap? Also, I have another question for those who proposed the flexible vent pipe and cap. Do any of you use this with engine pans? How do you route the flexible pipe? Any rattles? I visit this forum every day and it never ceases to amaze me how much I learn about the "A". Thanks to everyone for their contiued input and knowledge. Dick |

Re: Oil Blowby
bogdonj - Thanks for the pictures. I do appreciate it. I have oil blowby on my engine, but that is due to it being old and somewhat tired.
Again thanks,

Re: Oil Blowby
your welcome, Its not a SOS pad they are more steel wool but its a normal scrubbing pad. You can get them at any grocery store. Don't use any type of spounge or fabric that can rip apart. It's important to pull the pad down in the middle just to make 100% sure no oil happenes to slip by. Very cheap fix to fix a messy problem

Re: Oil Blowby
I use an accessory piece called a Fumaze. It's a very nicely made breather that routs oil and fumes under the car. Most supplyers have them.

Re: Oil Blowby
I too use the stainless steel scrubber pad in the cap with absolutely no blow-by.
If you want to keep the original appearance, you might want to read Brent's posts regarding the filler baffles in previous thread: https://www.fordbarn.com/forum/showth...+filler+baffle
