Blowing Hydr Filter Seal

[mrbrettbaker]

I've got a good friend with an 87? Ford 1520. 3 times in the last 2 weeks he has blown the gasket rubber out of the hydraulic filter, and the filter has been replaced twice. I'm a 30+ yr mechanic and I'm betting there is some kind of restriction or stuck bypass but I have not gotten a manual yet (ordered) and I haven't gotten up to his house yet to look. I am hoping this is something someone here has seen before and can save me alot of work? Any ideas would be appreciated.
Thanks
Brett
