Totally Dissapointed!!!!!

C130 is dead on. I recently re-ringed a 383 because an owner decided it wasnt running well enough, mistuned a brand new engine that actually had some poor wiring, and the rings never seated. I learned a little more lately about ring sealing. First, moly is a coating, not the ring material. It's srayed on and allows for very fast initial ring seating...Provided the surface finish of the bore is smooth enough, and clean enough. If it's too rough, all you do is wear off the moly in a few minutes running, and the rings cannot seat properly. In times past, you'd run ductile iron rings, anda semi rough bore finish, so the bore and rings wore into each other in about 500 miles. Now, they should be finishing the hone with a very fine stone to finish size, then using a plateau hone or brush hone to properly prep the walls for moly rings. Also, as C130 said, KBs require special ring gaps on the top ring. If the shop used std Hastings replacement rings for 318+.030, the top rings may have butted already. They must be opening up with a ring filer to get the "right" and safe clearance. Also, I use 30wt oil to assemble my engines. However, toom much oil on these rings and smooth surfaces will also make it hard for the rings to seat. There has to be just the right balance between too smooth and too rough for them to work. And too much oil on assembly can hurt this relationship. I now use WD40 alone on the rings if the egnien is to be fired within days. If it's being shipped, I use off the shelf 10-30, but very little. Like a few drops on my fingers, rub around the pistons rings, and hit the bores with WD40. Then assemble. I got that tip from several other large race shops, and it works fine, as long as the enigne fires right up after prelubing with a shaft. I've used plenty of HV pumps wiht no ill effects, but it is known to happen on occasion. The HV pumps were to help bandaid worn engines, not lubricate fresh ones. Use an HP one with the higher releif valve pressure but standard volume. I'd still do the leak down test. That will tell you if the rings are sealing. That test uses air pressure to see how well things seal, and has a gage that reads percentage leaking by on it. I use a MOroso one, but there are tons of them around.
