The past few weeks my 2005 Escalade ESV has been giving me a low oil pressure warning at cold startup in the morning. Since I now live in Dallas, this means nighttime temps below 40 or so. The warning goes away within 5 seconds and if I open the door I can here it tick pretty loudly until the warning display goes away. When the engine is at operating temperature, it has normal oil pressure (at least at the gauge). Has anybody had this symptom? I'm wondering if the oil pump O-ring may be failing on the pickup tube. Anybody have any experiences with this issue?
That's what I was thinking. Did you do it yourself or did you have a shop do it? I'm capable of doing this easily but am getting lazy. If you had a shop do it, what did they charge? At this point I would rather throw a couple hundred at not having to bother with it myself.
Re: Low oil pressure at startup in low temperatures
I did it myself as did others. Its not that bad of a job just a bit time consuming, I believe it took me under 5 hours IIRC but I also changed out the timing gear set as well since I had about 175,000 miles on ours and replaced the oil cooler lines.
