Well after the last oil analysis I’m thinking about freshening up my other motor. If the next oil change is more aluminum it’s coming out but I need a backup motor. The one I pulled out had good oil pressure still not sure how deep I should go into it just gasket rings and a hone? maybe put better cam in I know the 317 heads flow good just untill the other motor is good to go and I feel safe throwing power at it. I mean at the end of the day is the machine shop responsible especially if it is the bearings? I could see a part failure like bad lifter can’t blame that on anyone

So not to revive an old thread but finally took the motor out wish I did a long time ago I believe it’s the rockers .

damn wheel hitting the side

That's ... heinous.

How many are like that?

Lxjoshxl

A decent amount. Trick flow says gotta use the heartlands on their heads maybe it’s bullshit. But I should have pulled the covers and checked long time ago now the motors out feel like I wanted another build when I could have fixed this issue .

I've followed your thread. It's always nice when someone gets back with what was wrong.

Excuse my ignorance, but, what are "heartlands"??

jasons69chevelle

Been running mine a couple years without those rockers. I did get powdered metal guides though.

Lxjoshxl

Yes that was the main thing because of the guides they call for the roller rockers. And cattle the hartlands * are the brand of rocker they reccomend to use with Trickflow head. So after 18k miles should I replace and douche the motor as long as bearing look good. Valley cover off through the casting holes the cam doesn’t look bad. It was all fine powder never anything in filter oil pressure still good. Wish I figured this out before I did a whole build lol..

He means Harland Sharp rockers. And that's why I'll never run anything but factory LS rockers and won't use heads that won't accept them.

Lxjoshxl

Ls1formulation. I know I didn’t look into it much. Not sure how to remedy this or if it’s gonna have to be taken apart and cleaned all out.

I thought that's what they were , but I wasn't sure.

Well, anyway thanks Lxjoshxl for the update and good luck going forward.

Lxjoshxl

I wonder if I can replace rockers check bearing flush motor out and call it good again?

RB04Av

Aluminum powder won't really tear up anything. No damage done to the rest of the motor, fortunately.

I'd FOR SURE investigate why those rockers did that though.

Lxjoshxl

Alright yeah rb not sure if geometry was off or what. Just mad I didn’t realize this before building another motor I had the covers off at half the mileage and checked but the wear wasn’t as bad as it is now.

LS1Formulation

Judging by the wear pattern on the roller, I'd wonder if the roller itself wasn't truly flat across the face. When the rockers are torqued down, does the roller sit centered on the valve stem tip, or is it offset? If it's centered on install, but has thrust pressure to the side when running, either the roller is tapered, the valve stem tip is tapered ( less likely, since it can rotate ), the rocker stands on the heads are off in some way, or the rocker bodies themselves were machined incorrectly - or have bearings going out in them. I'd blue the tips of the valves and roll the engine over to look at the contact patches of the rockers. See if there's a difference between the rockers that have wear versus the ones that don't.

RB04Av

That's worse than a lack of centering. It's the result of the rocker tip wiping sideways across the valve or being tilted at an angle to the valve. Not only tearing up the rocker, but also wiping out the valve guide. Something is very wrong in that setup.

Lxjoshxl

What could be wrong RB? Pushrod length? I’m at 7.5 with the trick flow heads. But like you said it’s pushing left to right not up and down too much? I’ll call machine shop tomorrow to see if they have any thoughts.

RB04Av

Not push rod length. That much is for sure. I don't know much about your heads, so I can't be much help beyond that. Clearly though, the rockers aren't pushing straight down on the valves; instead, they're either canted to the side, or wiping across the valve stem tips. I'm sorry, all I can tell you is what to look at and what to look for, not what's actually wrong. That's up to you to spot. Maybe TF can shed some light.

Lxjoshxl

After getting time to take them all out the rock left to right while holding the two together on the shaft assembly. It’s like the bearings were bad or something. Either way Harland was nice and said send them in and they’ll replace. I’m just worried how much of that **** ruined everything else.

Lxjoshxl

So fully assembled truck flow heads I know it’s a ruler but you can see the variance. See of stock 317 in second photo for reference.

Old Buzzard

P rods into the head will shove the rockers to 1 side.
