Replying to @mdcameron immediately after making the first video regarding the odd lifter oiling issue, I decided it was time to inspect the oil filter before attempting to repair what *might* be just a symptom of a greater problem... as it turns out, my suspicion was correct. there is a significant amount of bearing material inside the oil filter. my guess is, as many people suggested, a damaged/spun cam bearing or possibly a rod bearing. I don't actually know exactly what work was done to this engine before it was brought to me other than the cam swap. so...as I often have to do, I informed the owner and told him that he can either leave the truck with me for a complete engine rebuild and no definite delivery date, or he can cut his losses and pick it up at his convenience. he chose the latter, so I will not be digging into this engine any further...so, sorry for that huge disappointment 😂 #bentune #hptuners #dyno #tuning #mustangdyno #dynotuning #gm #trucks #Chevrolet #Chevy #Silverado #lsx #btr #BrianTooleyRacing #mechanic #mechanicsoftiktok #racetruck #Wednesday #reply #engine #failure #badnews #ontothenextone #work #help #itshot
