Metal in my oil... Thanks Comp Cams!
So my tuner drained my oil, and cut the filter on a whim, and it was full of metal sand material. I wasn't sure what to think, so I just kept running it after the oil change (very low mileage) - Well, I checked my oil today before taking it for a ride, and there was metal in it, so I'm like what the **** is going on? I thought my 408 build (from September of 2012, with between 3,500-5,000 miles on it - I don't exactly remember) was falling apart inside. A friend of mine told me to pull rocker arms off and take a look, so I did.
I am using the Comp Cams trunion upgrade that was supposed to be the best thing since sliced bread.
All but 2 of them are spewing metal out of the sides. ******* pathetic. I know they're cheaper than the roller rockers or any other style of upgraded rocker, but this is ridiculous.
I'm using a texas speed texas giant (Also comp ground), with COMP 7.425 in pushrods.
And I just bought the yella terra yt6638 non ultralites to replace them.

That sucks. I'd expect better from Comp Cams.
Why would you use these over a stock rocker set up? I see no advantage over the stock rockers with these. Maybe a full roller, but fulcrum rollers are stock right? Are these 1.8:1, if so that would make sense.

I've never seen a trunion upgrade do THAT. That's... Idk what that is.
You couldn't GIVE me roller rockers to run. Too heavy. I ran upgraded trunions on my last build, and I'll run them on my new one coming up.
OP take some apart and inspect them.
Better yet, don't even disassemble them and send them to comp and see what they have to say about it.
Is it magnetic? And how's the oil pressure?

Oil pressure has been ideal. Exactly where I anticipated it to be, honestly.

Well, I popped one apart (not the right way, I pried the snap ring apart with a flat head and pushed a stud into the top, and used channel locks on the other side). The bearings inside the cages look ok, but then I shook them out into my hand, and after they rolled around, my hand was covered in the exact same metallic material that was all over my hand to begin with.

There is no way that metal came up through the pushrods. There is possibly no greater point of friction in the engine than the rocker arms. With modern ramp designs opening and slamming the valve closed at incredible rates the amount of abuse they can take is amazing. I think Radeon is just beyond what upgraded stock parts can handle. Oil filter should have caught 99.9% of it. The pump would be the main casualty. I would guess it hasn't been ran very long and that he has carefully monitored his new engine. Put some new rockers in it and roll.

Just saying it could very possibly be from somewhere else. It could have a faulty filter, pump, etc. That was not enough diagnosis for a good conclusion. Yes the metal could have came from somewhere else, got pumped up the push rods and stuck to the magnetic bearings and became magnetic. It could very well be the rockers. Good luck.
