That's a steal, when my oil pressure sending unit went out on my 2001 Volvo with a N-14 Celect Plus I paid $240.00 for one and that was from a Volvo dealer. At first I thought they were gouging me, but when I called my contact at another Volvo dealer they quoted me the same price.

 

I have 2000 n14 low oil pres. 830k miles. I want to change this things!

 

For the sticking brakes, as already noted, check the linkage parts you can reach in the pedal.

After that, I'd be blaming the brake application valve and the relay valves next.

To save an older valve, loosen off the supply line to the valve and spray the good lube of your choice into the valve, re-attch the line and pump the brakes a couple of times. There will be a cloud of lube come out the exhaust port, so watch your eyes, if doing this with a partner.

This must be a lube spray, not one with solvents. So forget the WD40 and friends. You'll have to spend the big dollars on a Krown product, or FluidFilm, or Termin8tr, or etc. Good air tool oil will do the trick as well.

Do not mix up the supply line with the signal line on a relay valve.

The other culprit for showing the brake lights would be a failing pressure switch for the wiring, which are cheap and easy to change. Be sure you get the right kind for your application, as some are normally closed, and some normally open.

 

holy cow..just dont throw a set of lower end bearings or oil pump in without correct diagnosctic steps.

1. start and check the oil psi with a manual uage you hook up yourself.
2. check oil for fuel or antifreeze. (oil sample)
3. run unit with valve cover off and look for excessive oil spray coming from rocker shafts. They have little allen screws that have a habit of coming out and causing low oil
4. check bypass's for scuffing/wear or broken spring
5. Check wear on 6th main bearing ( jost the lower side, and the upper part of the rod brgs on cyl #5 and 6 if you want.

start with the simple then move onto pumps and bearings
