help! Intermittent 4.7 oil pressure/coolant issues
Hey guys, i drive a 2000 WJ 4.7 (non HO) with about 170k miles. lately i've had a strange issue that i'm unsure how to pin point. The oil pressure has read very high, in the 65-70 range, where it is typically in the 45-50. this seemed to be resolved when i checked my oil level and found it low nearly a quart (oops). This morning the overhead unit displayed a message that my coolant is low, and my oil pressure gauge was reading in the 75-80 mark. This was on my way to the office and engine temp was at normal. after pulling over, checking oil and restarting i have seen nothing of either issue reappear. i might also mention that this is only a week after my ac compressor locked up, i don't know how or if it could be related but mentioning it won't help. I know some of this is vague, i will be happy to answer questions. Any thoughts or ideas are much appreciated!
