Hi guys,
That is perfect Sinista32, I wish i had that y onks ago.
After 3 or so years, last week I have resolved my Hicas issue after first start and runin of my new engine, however I can not say 100% what the issue was unfortunently. But I am pretty sure its related to the pump and or pressure control valve, as my previous post stated I did infact swap out my pump but didnt resolve it, however after the engine came out, i spent time checking and cleaning every sensor in teh system, one in particular which i didnt properly service last time was the pressure control valve near the alternator (drivers side). this time both thatsensor/valve and pump was the new additions and after first start of the new engine.. my issue has been resolved.
Unfortunently I had to do things in this order due to the engine built which is not helpful in pinpointing the cause of this issue, and in my situation it seems that maybe both the pressure control valve and pump were issues. (possibly)
Hopefully that picture sinista32 has posted is of use to assisting others resolving this same issue.
good luck
