Hi All,

Here is my 351 Cleveland on a test stand. It has fresh internals and runs nicely. Except for a mild hydraulic cam and related components, the engine is stock.

While it runs great, there may be some noise coming from the rocker arms. They are original.

My questions are:

1. How much noise (if any) should come from the rocker arms?
2. If they need replacement, should I go with rollers?

Thanks, Steve

It's been my exp that the rockers should be "ticking" away under there at a busy rate. If you have one louder one then of course... Rollers are an improvement for sure and I'm sure will be recomended. That stand looks good, does it work good??.. Does it shake around??.. would you anything different on your next run stand??.. I may try that...
I will try to determine if one rocker is louder than the others.

I suppose there should be a consistent noise coming from each rocker arm.

Are roller rockers available that bolt in place of the stock rockers without machining, studs, etc?

Regarding the stand, it works quite well. It does not shake or move. It has allowed me to readily work through the rebuild process on this engine and take care of details that may be difficult to address once it is in the car. It was very inexpensive to build (mostly scrap lumber) and the $30 radiator from CraigsList came with the hoses you see. The radiator is for a 1999 GMC pickup. There is not much that I would change next time around.
Hi Steve,
The noise may be as a result of your lifters, If they are anti pump up lifters they will tick, this is not a problem. These are so you can rev the engine without floating the valves , but if you determine that there is to much clearance I think Ford racing has the bolt on adjustable's, part number M-6564-C351.

Once you have the engine broke in and the first oil change I like to use Marvel Mystery oil, If anything is sticking "ie lifters" this will usually cure it while also polishing your wear area's- great stuff,

Looks like your having Fun,
Looks great! Mark

Steve,
I am anxious to follow your rocker decision. I am running the OEMs and would like a simple install of a roller application. Please keep us posted.

PS: I have never heard anything but bad things about Fram oil filters. My 2cents is spending the money on a good quality K&N/Mobil 1. Even the MotorCraft filters are much better rated than Frams.

I spent countless hours trying to solve the noisy valve train on my engine and came to the conclusion that certain cam profiles and lifter combinations along with the canted valves are just noisy. If they all sound about the same you should be good if the pre-load was check when the engine was built. This was verified by a well known engine builder and other Cleveland experts. The Pantera engine bay tends to amplify the noise as well.

True, Fram is a poor choice for oil filters, there are several pictures with the review at the bottom here. Personally I run a Pure Power oil filter. They are reusable (a "lifetime" filter)and when you take them apart for cleaning you can see any tell-tell signs of serious problems. Ther are a series of small magnets for collecting the metal particals, and since it is made of surgical grade stainless steel mesh, this filter both filters smaller micron particles and flows more oil than a conventional paper filter. Are they cheap? No, they run about $200. But when I see people throw down any where from $4000 to $15,000 on a killer engine and then spend five bucks on a cheap filter it makes me want to cry. In my opinion, the $200 filter is cheap insurance to keep your Cleveland healthy.
