Yella Terra Full Roller Rocker and hitting valve cover

[2Blew2B]

Mike or Anyone,
I purchased Yella Terra Full Roller Rocker Set and a chrome valve cover from Classic Inliners. I just had the engine redone and the Yella Terra Full Roller Rocker installed but they are hitting the valve cover. I had the machinist knock up the splatter plates but it is still hitting. Does anyone have the Yella Terra Full Roller Rocker installed on a 200? What valve cover are you using so it doesn’t hit?

Isnt the chrome valve cover very similar to the stock factory cover? If so you will most likely need to double up on the valve cover gaskets.

The Classic Inlines cast aluminum valve cover is designed to be taller to clear roller rockers.

I am using a clifford al valve cover and they clear easily, they owed me money on a return other wise I would have bought the CI AL valve cover, my opinion is to not worry about it and give MIKE a call and let him know whats goin on and I bet he resolves it very well for all concerned.

I already doubled up the gaskets but no luck. Also, can't be for certain but I think it may be hoitting the sides. i would like to n=know if anyone is running Yella Terra Full Roller Rockers and what cover they are using??

using the CI aluminum cover with no problems.

I've sold at least 100 sets, and this is the first time I've heard of a clearance issue. Make sure they are installed properly, and check the valve train geometry. If the block was decked and the head milled considerably, the pushrods may be to long? Other than that, I have no idea why.

falcon fanatic,
Classic inliners aluminum cover?

Also, mike I have read other post that say the deflection plate on the valve covers hit. But do you have a picture of the inside of th aluminum cover .

Ok I know what has been posted but i have found the rocker hitting on other post as well. So what i am wanting to know does anyone sell a taller valve cover?

The cast aluminum cover is taller and has clearance.

 

[2Blew2B]

Do you know it’s taller than the Chrome cover? Are you using the cast aluminum cover? If so can you tell me the height? I would like to compare it to mine.

The CI ALvalve cover will fit, I can't imagine Mike designing it not to. Unless you have something way out the norm, unfortunately the only thing I know for sure is the clifford AL cover will fit, I use it with yella terra rockers, but I am not a clifford supporter since JACK passed away.

 

[2Blew2B]

Yea I was just reading about the Clifford one. It says it is taller than the standard height. Oh, by the way does the one you have did it come with the custom gasket? How did that work out? I was reading the installation instructions. Yea I talked to mike but he said the Chrome one should work but it doesn't in my case. I am not a Clifford fan either but I don't want to get Mike's cast valve cover if it’s the same height as his chrome one.

How far are the adjusters backed out? Can you tell if the adjusters are hitting, or is it the body of the rocker arms? I just hate to see you order a new valve cover, from Cliffords or me, only to wind up in the same spot. These rockers are designed to fit under any of the valve covers without hitting. Doesn't matter if its a stock cover, chrome, or an alloy V/C. While the alloy covers are taller, the inside dimensions are the same due to the height of the ribs and the thickness of an alloy cover. Hence I'd be willing to bet an alloy V/C won't solve the problem. I could be wrong, but I don't think so....

Mike,
The problem is defiantly with the splatter shields. It is only hitting in the front and rear under the oil and PVC areas. I will remove the cover and measure and report back. Also, I am looking at getting a used valve cover from a guy around here and cutting the top off to see exactly what's going on. The guy that built my engine has been building performance engine in Maryland for 40 years. Around here he is considered one of the best. Not say the geometry isn't off or a mistake was not made but the cut off top should tell the story.

Seems like the only decent valve covers are designed by the factory.

Most of the aftermarket junk doesn't even have baffles over the pcv hole to prevent oil being sucked into the vent system. You have to use a rubber baffled grommet which is 50% efficient.

Clifford & classic inlines which seems like a copy of cliffords is just a pretty cover with no functional design features.

You purchase a performance valve cover for a chevrolet & made by chevy, it even has deflectors over each rocker arm to direct the spray of oil from the pushrod to the rocker fulcrum area for complete rocker arm lubrication rather than just spray to oil over the rocker arm and hit the other side of the valve cover.

I'm sure properly designed ford valve covers are of the same quality.

Both of them have proper sheetmetal baffles in the cover so oil is not sprayed even near the pcv area.

The yella terra arm is a quality product.

You just need to see where it hits & fix the problem. The rocker arms are not the problem. Outlaw.

outlaw,
We did hammer up the splater shields but of course it just takes a little piece just not of the way to cause the hitting. I really don't want to spend 250 dollars on a Clifford valve cover, but I would if that would instantly fix the problem. I have been working on her for 2 and half years and now its this little problem preventing me from putting her on the road. I have read other post here on Fordsix that talk about it hitting so i know i'm not the only one. Just frustrating. I just wish they CI sold a taller one that would solve the problem. According to Mike the ones he sells are the same height on the inside as the Chrome ones, that sucks. I'm out of town now but i will report height and final fix action when i return to help others out there.

Unfortunately, we did the same thing Clifford did when we designed our alloy valve cover. We both made the valve covers a little taller, thinking we would have more room inside. But we both forgot to figure in the width of the alloy and the height of the ribs, hence both covers have the same internal dimensions of a stock v/c. Eventually we plan to modify our patterns and make a new mold, but that won't happen until late fall or early next year.

Mike,
How is the oil shield designed? I believe that is the issue? Do you have pics of the inside? I think I would like to take you up on the offer.
