1988 Buick Riviera

Asked by Jun 26, 2015 at 06:01 PM about the 1988 Buick Riviera Coupe FWD

Question type: Maintenance & Repair

I have a 1988 buick riviera i bought
off a family friend it only has 132xxx
miles on it, my low oil pressure light
came on and my dad told me to just
keep adding oil (wrong as hell) my oil
(5w-30) was over 2 quarts and
caused a bad oil leak so i got an oil
change from firestone i dont think the
put the oil filter on correctly because
i have a small leak now comming
from the filter, and the oil looks thin?
I went from a car that can travel 5 hrs
to being woried about my car 20
minutes of travel can anyone tell me
of the cost i would be looking at as
well as the damage?

Too much oil will make the oil in the crankcase foam. When this happens the oil pump is sucking the foam (air) so your oil pressure drops. Check the oil level on the dipstick to make sure it's full but not overfull. I'd change the oil filter and see if it stops leaking. If you're good on both and the oil light comes on at idle I'd replace the oil pressure relief valve. It's a spring loaded gizmo located in the oil filter adapter assembly. If it's stuck open or the spring has lost it's tension it'll cause the light to come on. If that doesn't solve the problem then I'd just keep driving it. Low oil pressure at idle can also be an early warning sign of worn bearings. A thicker oil such as 10W-30 or 10W40 will help. But if it turns out to be worn bearings that's just a "Band-Aid". Eventually the engine will develop a rod knock. HTH. -Jim

was synthetic used? the seals will not hold it. it was designed for regular oil.
