Yes, acceleration G force is under load, more blowby. Deceleration Gs are under coast, less blowby.

...and I assume that this theory applies to both BBs and SBs? Hmmmm |

BTW, this is opposite of the configuration that I have on my SB.
Seems to me that swapping my breather/PCV shouldn't be an issue. 😕

http://www.clubcobra.com/photopost/d...0BBEB6C13.jpeg Thats the same PCV set up on the 390, in the El Chico racing..party..bus...???
There’s a Cobra painted on the rear bumper.
El Chico manager I bought it from in Texas (1982) said Shelby did the paint and put on the 65 C4AE heads and Hooker Comp headers, that Carrol was a friend of his
Life’s good

On production original leaf spring Cobras, the PCV valve is on the left valve cover.

Why would there be more oil splash at the back of the valve cover vs front of the valve cover?

Because the engine lower at the back, and oil moves rearward under acceleration. Yes, oil also moves forward under braking, but the engine presumably isn't revving as high, so therefore not pumping as much oil. |

Not on the early small block cars. The 260 and I believe a few early 289 cars, there were no openings on the valve covers. The oil filler tube was on the timing cover right side and was also the breather. Would love to know what serial number when the street cars changed to oil filler and breather on the valve covers? The race cars changed almost immediately after the came here. |

Yes, I know but the majority of production 289 engine cars had the PCV valve on the left valve cover.

There were instances of PCV’s on either driver or passenger side, depending on carb setup of street 289s (post road draft tube) straight from SA. Have the pix.

The PCV on my Roush, which has nothing to do with Ford, is on the driver side. They built the engine and put it there. That's all I need to know. Fine by me.

I think this might help with the question on where you can put a PCV valve on a ford engine. The article is from July 2016, and it is how to make a 302 Roller Cam engine look like a 260/289, to fit in a Tiger. https://teae.org/s22-replace-260-289-302-roller-cam/ In it, he states, "If necessary, you can move the baffles up closer to the cover surface but don’t run without them. They are there to keep oil from being sucked up through the PCV." Of course we now have spacers to raise the valve covers, but the baffles are key to keeping oil where it belongs! Then I notice in his engine photo, the PCV is on the right cover at the rear. I thought that was just personal preference, but every Tiger I could find had it in the same place. So I went looking for original Shelby Los Angeles Tiger, (LAT) valve covers. Sure enough, all of them had the oil filler tube on the left cover in front, and the PCV on the right cover in back! I am pretty sure that the guys at Shelby knew what they were doing, and most likely Ford had a say in it also. |
