Brazed rocker

[wilco]

While setting my valves I came acroust several brazed rockers. Is this common?

HMMMM I don`t like it but I`m sure the experts will chime in on this on.

Those lock washers don't look they belong there either

Why is it there? I looks as if it's restricting oil to the valve tip.

I don't think so,, Do a search on this subject, I kmow Clinto did have to replace a freeze - expansion plug on one of the cyl. heads on his engine and took some really good pics of the process, compare those rocker arm pics with yours, but to me the ones shown in your pics look like they really need to be removed from service.

It sure looks to me like it would restrict the oil flow also.

Yes it is! Notice no oil in the retainer on that cylinder? The push tubes and valve/rocker lever tips get oil from the oil hole in the center of the lever and it runs down over the component to be oiled. I'd replace it or as many that are like that.

Thanks for the plug, DW.

I went and looked at all my pics ( http://s9.photobucket.com/albums/a90/clinto1/M35 Head Gasket Swap/?start=all )

And unfortunately, I didn't have a good pic of the rockers from the top. But I think I would have noticed that.

I have to say, I don't like it. I'd swap that rocker.

And those lockwashers aren't right, I've never seen a lockwasher on a head/main bolt. A flat washer sure, a lock washer? Nope, that's what torque specs are for.

Looks like a "Field Fix" to me.

Over the years, I have seen some really, really cobbled repairs/fixes on military equipment. The above is in the "ho-hum" category. Comment: When that engine is running, its an "oil atmosphere" in there. So I wouldn't be too concerned about the brass being in the way. But, it looks like the hardened wear tip that does the pushing to open the valve, was the object of the repair. In some sheet metal repairs/applications, brass is good. However it does not stand vibration well. I would replace it when I could. It would be real easy - maybe possible without even disturbing the rocker assembly hold-down cap screws (with the lock washers). They are not head bolts. I'd replace the lock washers with hardened ones, if they are sued else where, and re-torque everything, including the head.

Good your setting the tappets, few do that anymore, in a tune up. I like my engines, 100%!

I wouldn't take a stand on the oiling issue. I can see it restricting "flow" via the troth, but I also agree with the above "oil atmosphere". I dunno how scared I'd be of that. I don't like braising for that type of movement, stress, general abuse however. I'd change it on a bad feeling, but again I can't say for sure.

As for the lock washers, those bother me. Bad environment for a lock washer for sure. They should go. They're going to cause a failure, not prevent one. Flat washers, and torqued right, those bolts should stay forever. No washers and torqued right, those bolts should stay forever. Split locks and torqued right, those bolts are coming back out. (or more accurately, the washers are coming out from under the bolt heads) Maybe not tomorrow, maybe soon, or maybe not for fifty or a hundred thousand miles, but they don't belong there.

change it and remove the lock washers.
