Mrad01, do you have an update on the check valve fix? Did it remove the startup rattle for you?

I have the same startup rattle and it definitely seemed to be lack of oil to the upper part of the engine. If the engine has been stopped for several hours the noise will be present. If the engine has been recently ran, then a restart will not have the noise.

Do you have a photo of the check valve(s) and/or their location on the engine?
