I just changed my oil and filter. Long story short I goofed and damaged the sending unit while trying to get at the filter from above. I replaced the sending unit, checked that the oil level was correct, fired it up only to find that my oil pressure was almost 80. Please advise. My oil pressure was normal before I started, ranging from around 60 at startup to 25 at warm idle. I have had the truck for several years and not had any problems as far as oil pressure. The only other thing I did at the same time was flush and change the coolant.
