My machine shop guy told me my motor was all clean and ready to assemble. looking down the lifter bores I could see some crap in one of the oil holes. Made me wonder if it was truly clean. I knocked out the freeze plug on the rear of the motor and removed the pipe plug (that I don't remember was even there!) looked down through expecting to see the light at the end and even ran a bore scope part ways in and nothing but DARKNESS.
Break clean, shot gun cleaning rod, Qtips and lots of patches... knocked out a big clump of goo and all sorts of nastiness.
Moral of the story...It's not truly clean until you make sure it's clean. Zestfully clean.
@Tom442...good post, members need to be aware of the info you provided. If missed, details like this can make a ni$$$ce rebuild go south in a hurry. Bore brushes, lots of HOT water, detergent and time will take care of this on a bare block even if the machine shop did a cleaning.
edzolz suggestion is mission critical. The location of the galley plugs with a description of each would make a good sticky as would motor mount selection and timing chain/gear orientation. Perhaps a moderator will consider this.
Same when i got my block back i went over it w a fine tooth comb. There wasnt much to find but in head oil returns I discovered some residual goo that needed removal. In the end there wasnt alot but knowing it wasnt there any more was worth the effort.
I learned years ago to remove all galley plugs and use drill rod of the appropriate diameter to push out accumulated gunk. The wads of sludge will survive the hot tank bath. Further more to ensure the best results it is prudent to clean the block inside and out with solvent/soap/hot water/scrub brushes/bore brushes/power wash as much as possible before the hot tub.
