i have a 98 dodge durango with a 5.2l. the truck had no oil pressure when it got up to temp and i got a knocking sound.i changed the oil pump.now i have good oil pressure but when the truck gets hot i still get the knocking.but only when it gets up to temp.i use castrol 10w 40 oil.if it was the main bearing it would do it all the times. it only dose it when it gets up to temp.i think that one of the lifters is locking up as the oil gets out.who can help me

 

Need to isolate where the noise is coming from. Big difference in sound between a main, rod, and lifter knock.

As the engine warms, the tolerances open up. Knocking once warm is a warning that things are going to go south, possibly in a big way. Might be time to start looking at a replacement motor.

How many miles on it?

 

Welcome to DF! Check out the 1st gen Durango section here >> https://dodgeforum.com/forum/1st-gen-durango-69/

 

it has 148,000 miles. i took a listen to the motor and on the bottom there is a little knocking sound on both sides. the top of the motor on the driver side there was a little sound on the passenger side there was a lot of knocking.

 

Pull off the passenger side valve cover, see if anything is obvious.

 

thank you im going to do that soon. ill keep you up to date
