Oil sensor 2007 Yukon XL 5.3

Asked by Jan 03, 2017 at 11:58 PM about the 2007 GMC Yukon XL

Question type: Maintenance & Repair

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.

First thing is clean the little screen in the oil pressure feed tube where the sender is mounted, then find a high detergent motor oil and 3 quarts of Rislone and some good quality oil filters, change the oil and filter and add 1 quart of Rislone, drive for a thousand miles keeping a watch on the oil color, if it starts to get black before the thousand is up, drain the oil and change the filter and add another quart of Rislone with the new oil, again drive another thousand, after the third change you should start too see an improvement in the oils abality to look cleaner longer, after the third oil change use a high mileage oil and a good quality filter, that should buy you some more time before needing to tear it down and hot tank the block for a rebuild, or an engine replacement.

Totally agree, and the low oil pressure reading would be from that plugged screen under the oil pressure sending unit, as tennisshoes mentioned.

The screen, it is all about the screen under the oil pressure sensor.
