Timing cover and Hpop gasket questions
Thanks for letting me into the group first off. I bought a 1997 f250 cclb and it has 308k on it and runs great but after pulling the Hpop and reservoir off
to replace a leaking mounting gasket I realized that the reservoir gasket is a partial gasket with the grey ford silicone? The partial gasket from what I understand is only for 94 and 95 and the motor has a superduty Hpop and 3 chamber Hpop mounting gasket? Maybe this is why my reservoir drains after sitting for a few days and the leak at the mounting gasket is because it's supposed to have the 2 chamber gasket? I'm so stumped here I have owned this truck for three years and it's been great no problems but a small oil leak in the valley which is the hpop mounting gasket. So maybe it's had a motor swap too. Does any one know which mounting gasket I should use the 2 or 3 chamber gasket. Thanks in advance..sorry for the long post

Re: Timing cover and Hpop gasket questions
If the reservoir has 1/8 NPT threads for the oil pressure switch and inspection plug, it is the older one. If the switch and plug have straight threads and o-ring seals, it is the newer style. If it is the older style it will use the 2-chamber gasket, but the HPOP pump body needs to be the older style as well. If a later SD HPOP is used, that is why you get the draindown issue (earlier HPOPs had a built-in check valve to prevent the draindown. Later reservoirs and front covers were changed to have a standpipe built in. The HPOP gasket was changed to the 3-chamber and the check valve was removed from the HPOP at the same time). Cheers!

Wow thanks for the details Patrick it's looks to be that I have a different motor or older cover. So since I already have the 17 degree pump how could I make this work I read about having terminator engineering swapping the guts but I don't have two pumps unfortunatly is there anyone that sells a 17 with the check valve in the pump? Thanks for the help it is greatly appreciated
