rod knock ftl

Time for a full rebuild. Either they fucked up the oil change or your bhg got coolant into your crankcase and got things real hot because of the friction and wore out the already worn bearings. It was inevitable if you have been hearing knock for a while. When you hear a knock it is bet to shut it off right away and get it towed to a place it can be torn apart. The more you drive on it the less salvageable the parts get not only on the bottom end but the whole engine because all the debris will get into the head and cams etc.

Remove the oil filter and open it up, check for any bearing material.

yeah, theres no doubt about it, rod knock = rebuild/replacement. were you running petroleum oils?

could have been a bearing in one of many places. at the crank or at the piston. if the oil put in your car was different than what had been in, there may have been a higher detergency in the new oil which could have pushed a bit of sedement around. could also have been a really thin oil compared to what you'd been running.
