Have Jeep Questions? Ask a Jeep Repair Expert for Answers
Good afternoon and welcome to JustAnswer!!My name is ***** ***** I have worked for a Chrysler-Dodge-Jeep dealership for 19 years and I will do my best to help.
starting a high crank weak sound What kind of noise did it make? Also if your oil psi is only 25 then thats on the low side. If you heard a internal engine knock then you will need to drain the oil and inspect for metal debris and if found then you will need to remove the engine and tear it down to inspect.
If you need anymore assistance feel free to reply and don't forget the RATING before leaving the site!!Have a great day,Brad
Do you have a recording of the noise?
I would start by draining the oil thru a paint strainer to see if you have any metal debris, and if so then you need to pull the engine.. If not then you should be ok but you will need to narrow down the noise to address it..
I would attach a manual oil pressure gauge to verify it's actually high and if so then you have a bad oil pump and it's pressure regulator is bad..
