Thanks for all the suggestions. Yes we have added rubber isolation We repacked with OEM I normally only buy the supream green from Texacone when I can. We have even unbolted the pistons from the cross head and lowered them all the way. Pistons are direct connect no chains or cables. Adding the pro-vantage (same as cat oil except for the price) We have added to the tank and are having our machine shop make a custom fitting to go from our high pressure pump to the metric bleeder hole. I hold out the most hope that this will cure the problem but wanted to hear you guys opinions.
