Valvetrain noise in new engines
#11
Thank you for all of the comments, I don't feel there is anything seriously wrong but pulling the valve covers & physically checking the valves is not a bad idea. I can run them some more on the trailer or around the marina to see how things go, I am fortunate to have a marina literally in my back yard so dropping in the water isn't a problem. Big Jim this weather has been just crazy up here, The river has raised almost 10ft & dropped 4-5ft in a week and a half. I will put some more time on them before I start prop testing & if I find any problems I will let you guys know. Thanks again for your time. Randy

I had my Crane's set nearly exactly like RMB posted.
3/4 of a turn past 0 lash, tighten the poly lock and then maybe another 1/8 turn with a wrench while holding the poly lock in place to get them real tight.
They had "tick" to them, but all was good for 150hrs+ when I sold the boat.

Pull the valve covers and check lash just to be safe, I had comp cams poly locks fail before (brittle) and they backed off wreaking havoc to my valve train, back then switched to arp locks and ran that set-up trouble free for quite a while. The Canada guys don't have alot of faith in this Bullet guy, I hope you don't have a real issue, Smitty
"Mixed reviews. Some guys have had his engines in their boats for years then an equal amount of guys (like my buddy) barely got out of the Marina before it self destructed. Taken apart and shortcuts all over the place."

1/2 turn past zero on my morels and they are super quite. 30wt oil. 60lbs at idle 60lbs wide open. Even after 5000 rpms for hours 60lbs and quite lifters. One other thing ill throw out. If the distributor is not aligned with with the oil passage way then the lifters on the right side of the motor will not get oil. Best to run through the valves and go from there....
