Yes, with the double arrow circle, it is a factory rebuilt engine. > did vw change cranks for new regrind the existing was a new cam fitted > will they have fitted new heads anybody know what was generally involved > when the rebuilt an engine ? All engines were completely disassembled including all studs. The 2 case halves were then trued and the mains and cam were rebored. If the mains didnt clean up to standard, they were then bored oversize, and the thrust surfaces were recut. They would use reground cranks, and new cams. Lifter bores were resized if needed. I have seen these knurled to bring them back to size. All lifters were new. All oil pumps were new. All rods were completely rebuilt and resized. The cylinder mating surfaces on the case was cleaned up. If the case was machine enough to effect the deck height, shims were added between the cylinders and the case to bring it back to stock. Cylinders were bored oversize, and over sized pistons were installed. The oversize was in increments of .25mm up to 1mm over depending on the engine. Most common was .50mm (.020"). Heads were rebuilt in many ways, welding, remachined mating surfaces, including aluminum shims if too much needed to be removed. New valve seats and guides were installed. Missing cooling fins were welded back up. All spark plug holes were repaired. either with a steel insert, or if they were too bad, they were machined out and an aluminum insert was welded in. All exhaust studs were replaced, some with oversized stepped studs. All valve were replaced with new. All new valve springs and keepers. rocker arms were completely rebuilt, and all adjusters were new. All new push rods. Flywheels were reground, and if needed, the starter teeth were machined off and a ring gear was installed. > i do belive that they also always left off any engine number so you > could get your original number stamped on by the dealer or? The did not put an engine number on the engine. Just the letter designation to show the displacement. the dealer was supposed to stamp the owners orignal on the engine. Does that help???
