if you are getting mismatched readings from the heads then its the hpop that is acting up

sweet wheres the best place to order are get mine sent to for a rebuild ? ty

[kanuck15]

Well you can track down used ones on here for 100 or so. They have miles on them but are usually take offs when someone went bigger. A T500 is a stout pump if you have power plans in your future but will run you 450 or so

k is there anything else i should change while in there changing my hpop like irp valve etc ty

[kanuck15]

IPR? yeah but that can get expensive. They arent a cheap piece to replace. Im gonna link this into a more populated thread and see if someone else wont chime in. I still say its the HPOP if the pressures arent equal but I could be wrong

It sounds like an oil supply issue to me as well Joe. When was the last time you changed the oil. And is the hpop Res full before and after the little episodes?

[Patrick Feeley]

If the readings are uneven between heads, I'd be tempted to look at injector o-ring issues. Maybe pull the valvecovers and look to see if oil is coming out around the base of the injectors while cranking or running. Cheers!

If you suspected a low oil pressure problem, in the LPOP system, make sure that is good before continuing on with anything else.

k i will check into the hpop res full if so i guess i will tear into her lol ty all
