2006 King Ranch with 5.4 3 valve engine
. oil pressure gauge works intermittently, but when it does has good OP. Has mechanic check pressure and was told pressure good gauge faulty. Replaced both cam phasers, chains adjusters. turck has run fine for 20000 mi since. BTW truck has about 155000 on it. Just yesterday noticed a tapping in the top end of engine, small hammer tapping noise, like valve train. Truck still running great, full of oil, recent change, running cool. Any Ideas?
JA: How many miles are on the vehicle? And when was the last time it was serviced?
Customer: 155000, last serviced at
JA: Are you fixing your vehicle yourself? What have you tried so far?
Customer: I will be contacting a mechanic I suspect.. Vehicle has 155000, and had last oil change 2000 ago. I just wanted to know what I might be looking at?
JA: Anything else you want the mechanic to know before I connect you?
Customer: for the past yr. the truck has and still runs great and cool. As I said oil pressure gauge works intermittently and when it does shows above half way. I realize it is only an idiot light per se.
