Once you shut it down it will not restart untill the oil cools down enough to thicken back up to where it can build the 500 psi to start.
Thank you, very easy to understand.
Found a suitable video with the same engine and the problem.
for 35 - 40 seconds narrator moves the oil pipe. We have it hanging out stronger on the higher amplitude. Most likely this is a leak at the marked location.
Is there a repair kit for this damn thing? I have to google, but have not found a single detail and guidance for replacement. Thx!
