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?
do you have solution to your cold start loud noise? i had the same issue..pls share if you have solution to this..thks
