Bongo drums in exhaust

[okie18]

So I thought I had just bent pushrods at D4D, turns out it's something else to. Replaced the push rods (10/12 were bent) and I still have bongo drums playing in the exhaust and sometimes the intake. Only out the exhaust when it's up to operating temps though. I'm leaning towards a loose valve seat/s since it only does it when its warm.
My other thoughts were a wiped cam lobe/s, bent valve or I pulled a Cato and its a bent rod :hehe: Any ideas or someone that's ran across this before?

Burnt valve seat or bent valve. either way it's tear down time!!

Valve seats are loose. Have seen it in a couple times. One was an 03 and one was an 04.

I've been waiting for the day they would come loose. Looks like the wait is over

Well durr, it's been collecting dust since I swapped push rods. I'll be calling you for a head gasket kit sometime in the near future.

Ah, I didn't expect the stock push rods to last at 800+ for as long as they did anyhow.

You have no clue how much I miss texas, besides the traffic.

Are you sure your pushrods were the right size? I ordered some that were too big diameter, wouldn't seat in my tappets and caused some issues like yours.
