Well my car oil pressure went way down after driving in the snow. took it home and changed the oil and it did not change things at all. the oil pressure is all over and im sure its not just the sensor because the tick of death has returned to my car. what should i do, its making me mad:banghead: one more thing can i take the clutch out of my 90 loyale and put it in an 87 gl with a dual range.

reseal/replace oil pump - it's not that hard to do at all, and it will fix your problem - might take the oppertunity to change all those leaky front seals :rolleyes: (and timing belts)
as long as both cars are 4WD I believe the clutch is interchangeable, but you might as well buy a new one (given labor and everything - OEM lasts the longest) - don't forget to have the flywheel turned when you do the clutch change

replacing the oil pump involves taking the entire
front of the engine apart

from removing the rad (to gain some room to work)

right down to removing the front crank drive pulley and timing belt drive gears.

The T-belts and covers must come off also.

doable yes, easy?? I guess that's relative.

I would try changing the oil to Castrol 20w/50 and a half pint of MMO.

Much easier and this solution (excuse the intended pun)
has worked for many.

but

if you are going to "yank the lump"
to do a clutch job, do it then.

In my opinion - using a used clutch disc is well
"the thrifty man oft spends the most - time"
along with
"Do it once and do it right"
come's to mind.

well, when I did mine was after it had been front-ended when a moron pulled out in front of my mom going the wrong way - so compared to the bodywork I was doing at the time, it was VERY easy for me, and I already had the front end apart
Skip also has a good suggestion for a temporary fix, but realize that the pump still needs service
I generally do not run more than 15w-40 b/c my lash adjusters start sticking open, but with Marvel Mystery Oil you should be fine

i hate to admit it but i think that you are right, i need a new oil pump, because it used to run fine before and even after an oil change, and im using 10w-30 its still ticking and the pressure is all over.:(

IMHO you prolly don't need a new oil pump - just a re-seal. I could be wrong, but usually a re-seal (and make sure to put a dab o' gasket goo on the two block mating surfaces where the mickey mouse o-ring site) will work wonders for oil pressure and lifter noise.
