Can someone please help me make sense of what might be going on here… Long story short I had excessive valvetrain noise when I bought the car, it was stock at the time. I had a cam installed a couple years ago and the valvetrain noise continued. Due to finding metal in the head valleys, that was magnetic, I had the motor pulled and tore down. (That particular metal was valve tips being ground down I believe) The machine shop said everything looked fine except the heads had damaged valve seats. The motor was put back together with all new bearings and a fresh valve job and all new valvetrain parts. Recently I had new heads and a new cam installed and have about 400 miles on this past oil
change. I did an oil change just as a flush since new parts were installed. The motor sounds very smooth, runs good and made good power.
I cut the filter open and this is what was in there… none of the material is magnetic so I’m assuming it’s aluminum. Now, everytime I’ve done an oil change in the past this is exactly what the filter has looked like… why am I getting so much metal in the filter every time?? Oil pressure is normal also…The machine shop said everything looked fine internally so what am I missing?! Maybe this is just leftover debris from when the heads were damaged previously?! And none of this metal is from cutting the filter housing, I am carefully using a special filter cutter that makes a clean cut. Surely this much metal debris in the filter can’t be normal
I will be sending a sample to Blackstone after I get some miles on this new oil.
