THE RAM WORKED AS IT SHOULD

I bought this ram to replace an old jack with leaky seals in my engine hoist. The old jack had issues pumping up, but held its position indefinitely. I have had to have multiple Vevor rams as replacements, both with the same failure mode. The first new Vevor jack I got pumped up fine, but would quickly loose its pressure/position over a few hours time. Vevor sent me a replacement second ram, after a bit of back and forth with their technical support team. Unfortunately, the second ram has the exact same failure mode. Not matter how hard I tighten the hydraulic bleed valve, these rams will lose their position over just a relatively short period of time. It works okay to pick up an engine in the hoist, but I do not trust it to maintain that position for more then a few minutes, it will drop slowly with no load, I would not trust it unsupervised with a load. I've attempted to talk to a real person in the technical team, without success. I would like to know how to fix this as I have little confidence a third unit would be any different.

smaller than expected but it does the job
