In Feb just after I took my car to Texas for a run of about 200 miles my engine started to pop as I was loading it into the trailer to come back to Tulsa. When I got home I changed the
oil and found metal on the magnetic plug. I immediately pulled the
oil filter and took it to my machinist who cut it apart for me. More metal, parts of a spring and bearing material. I pulled the engine and took it to the machine shop and they found I had ground the bottom out of several of my lifters. I had ran that engine all last summer and fall plus I had taken it to Run and Gun (where on the last day I broke my back rocker arm). I don't know if some of my problems with the lifters started then or they had been slowly grinding away. But I do know my whole engine was junk after loosing all those lifters.
Cut your filter apart and make sure you don't have parts in between the folds of your paper filter. Be sure and check your bearings and
oil pump. Pull the caps on #7 and #8 bearings and rods and look at them for wear. If you have any debris in your filter you have a lot of things to replace...I did.
Check your plumbing on your oil cooler. If you are looking at your adapter plate you should have a AN 10 fitting in the 5 o'clock position and one in the 11 o'clock position.
The fitting in the 5 o'clock position is the outlet and should go directly to the inlet of your remote oil filter. The outlet of the remote oil filter should go to your inlet of your oil cooler (if you are using one-otherwise back to your adapter) the outlet of your oil cooler should return your oil to the adapter plate on your block and connect to the fitting in the 11 o'clock position. If this is contrary to anyone elses plumbing please feel free to jump in. We took my old block and put a light in the hole from the oil pump to the outside of the block.
I know you probably know all this but it may help someone else possibly. My lessons of late have been quite expensive.
