70 is little high for the oil pressure. It sounds like their could be some blockage in the oil holes that run to the top of the engine. The ticking could be coming from the lifters or valves not getting enough oil.
the wheel has to get changed you ediot
Not that familiar with Jeeps, but you could have a collapsed lifter, or you might have a rocker arm out of adjustment.
Take it to a mechanic
If you hear it only at idle and sounds faint, it is your rocker shaft. They wear on the end and makes a slight ticking noise. Mine has done it for over 100k miles and no problems. I hope you have done reg maint and kept oil changed.
the ticking noise is a small exhaust leak close to the exhaust headers or exhaust pipe near the engine.
The ticking noise is the metal cooling.
The fuel injectors make the ticking noise you hear at startup, especially when the engine is cold (colder temperatures).
if ticking noise is in engine, u most likely have a worn hydraulic lifter. check oil for correct volume and viscocity
yes, my 2000 grand prix gtp is losing power and makes ticking noise.
could be a lifter sticking
Is it a lifter ticking?
from which part of your engine is the ticking noise coming from. if is the TOP it would most likely be lifter noise.try using a thicker oil.
