Oil sensor 2007 Yukon XL 5.3
I have a 2007 Yukon XL with a hundred and
forty-two Thousand Miles. I replace the oil
pressure sending unit about 45 days ago.
Just last week the low oil pressure sensor
came back on. A trusted mechanic drop the
oil pan and indicated there was a handful or
two of oil sludge in the pan. Indicated that I
had a major engine issue Brewing. Would
like your thoughts. Never had any issues
starting or knock. Would like your opinion on
what to do next.
