Aight ppl i have a 99 gsr with an obd1 jdm gsr swap fully built head manley valve train pro series +1 cams port n polish valve job etc.... STOCK BLOCK... I have an oil psi problem 18 psi at idle and while im driving down the interstate the oil pressure fluxuates from in the range of 80 down to 50.. It never moved befor i had been running eneos and switched to mobil 1.. Im in the stages of buolding a block but i need to keep ole girl running and i dont want to throw a rod... Is there any chance i will damage the head

Well if oil pressure drops your more likely for the engine to lock up than throw a rod. But the head does need oil to if the oil pressure is dropping and the head isn't getting enough oil yes it will fuck up the head.

Did you try a new pressure sending unit?
Is the oil pump going bad?
Did you troubleshoot at all?

You have to pull the oil pan to get to the pump.

Is there a write up on this ive looked on honda tech google ci

Dough_Boy.

If you can't look at it and figure out how to do it you need to let someone else look at it.

Yea, get a Hanyes

Wait... so you're in the process of building a block, but you don't know how to replace the oil pump? Isn't installing an oil pump part of building the block?

For a how to, as Humongous said, get a Haynes, or try on Honda-Tech.

Maybe i should have been a little more clear. Im geting a block built and i would like to save some money in the mean time so instead of forking out 600 to get an oil pump installed i was going to try it myself
