67/68/69 cuda dilemma
If you're going to use a 90-degree oil filter adapter, be sure to take the pipe plug out of the end of it and brush thru there too. I soaked the piss out of mine and just knew I had it clean. Looking at that plug got the best of me and I took it out to look. You shoulda seen the crap that was caked in that passage! :eek:
