Hello,
Looking to confirm my suspicion. Little history if you read this thread first
http://www.tahoeyukonforum.com/forum/showthread.php?t=68191
So a week ago my friend calls me and says he is getting Traction control lights and stabiltrak off message intermittently. He also said engine oil pressure seemed lower than before but no warnings for that. I told him to bring it tow work and we could scan it. That day, he said at a stop his low oil pressure light came on with the shutdown message on the DIC. He checked oil level and it was good. After waiting a few minutes he restarted and all looked good but he now had a check engine light as well. Well, I hooked up the scanner and got a P0011 along with a C0561. Using the Torque App, the oil pressure was showing less than 20 psi at idle and dropping as it warmed up. No noise from the engine. He ended up driving it home and today brought it by my house to replace the oil pressure sensor again just in case the replacement was bad. I checked the oil and it looked odd so I decided to change it first along with the filter. The oil looked somewhat creamy but no free water. I stuck a magnet in the drain plug hole and it came out full of metal shavings. I wiped it and tried again and got a bunch of metal along with some flakes. After draining the oil collection pan I found some more silver metal flakes along with a lot of fine metal debris. My guess is the oil pressure reading Is true and damage has been done but the lack of knocking or ticking making me wonder. Has anyone seen this? I went ahead a cut the filter open expecting to find a lot of metal but I didn't. I refilled the crankcase with fresh oil and started it. Pressure went up to 40-45 on the gauge and slowing dropped back down to 8-10 at idle. Any thoughts/suggestions? I already told him I think it might be real bad. Engine has 130k.
I can try to attach pics of the drain pan if that helps.
The flake in the picture is not metallic. This is the largest piece. There are more much smaller pieces in the pan.
