As I was looking around, I saw that Morel's instructions says not too clean out wheels and lifter bodies...just wipe clean with lint free cloth and oil down the bodies and the wheel. Well, when I got mine, they where in brown box and no instructions. I did what I normally do.....clean the grease out of the wheels and soak lifters in cleaner. Then blow brake clean thru the oil hole. I stop when the crud stops coming out, air dry (doesn't take long) and then drop all of them in a bucket of oil over night. Interesting as Morel's instructions tells you straight out not to do any of what I did, but all lifter companies that I had dealt with in my lifetime say to do what I did. Any of you guys that have the noise issues follow Morels instructions or did you prep them the normal lifter way like I did. Again, mine would just have some quick clatter when started up after sitting for say a day or two or more, but would quiet down real quick. Nothing abnormal I felt. |
I did not clean them, I followed their instructions. It was different then what I was used to but I kept in mind they were High RPM lifters so knowing they were different I didn't put much thought into it.

That doesn't make sense (I'm not questioning your experience just thinking out loud). If at one turn (.050 preload) they were quiet, why wouldn't the oil pressure fill the void and take up the slack of another .025 inch (half turn)?
I believe there is close to .150 inch of travel, so at one turn there is still .1 inch of slack, half turn .125 inch. Maybe I will turn mine up to 1 full turn. |

No idea but I have video to prove it...

Did some research and talked to Amsoil...changing oil weights won't make a sh|t bit of difference.
The kinematic viscosity of oil at cold is nearly all the same between 5-50, 10-40, and 20-50. Granted there might be benefit in changing to a lighter weight oil, it will still be like sludge at cold. |

Ok, I'm going to start at 1 turn then instead of a 1/2.

I do know that the Amsoil 15/50 is more like a 10/50 from what they told me. They said they use the 15 number more for marketing purposes. So I'm told... |
I pour oil in temps down to -20F. I can tell you all about cold pour from all weights and conv vs synthetic from, again -20F to 100F.
Yes, I use to have oil racks outside. And I found out real quick the advantage to synthetics when temps got down say under O*F. Pour points, IMHO, has everything to do with cold start pumping rates. Anyway, maybe I'm different, but I rarely start my boat under *65F-*70F. And, when I have a hyd lifter euipped engine that is going to see say 5400+rpm, you bet I'm using a thicker oil like 20w/50 and at min good 15w40.. Lastly, I mentioned it earlier and I'm dead set on this one. Run the weight of oil your engine (clearances/use/temps/etc) wants / needs. Running a certain lower weight for a lifter kinda makes me say, WTF ! There, I said it, lol. |
