Yes, another ubiquitous engine noise question...
Most of what I could find all pertained to 2.3L motors in this forum, so I'll take a shot a question or 10 about the 2.5L.
Lately i have notice a knock, or tap in the morning when starting up cold, that is gone by the time i get to work. The commute is a few miles city streets, couple lights, then 30 miles of 70mph freeway driving. By the time i pull into work i don't seem to notice the noise. As of today we have about 244,300 miles on the motor.
my question simply is: are these engines prone to any particular failure type at these higher mileages? Rods snapping, piston slap going outta control, internal rotating items that seem to just go poof after 250,000 miles?
I haven't gathered much info, but a trusted person has listened to the noise and cannot make up his mind what hes hearing. the best we can figure is piston slap, but its just not like what you normally hear everyone posting up for rod/piston noises.
i plan to do a compression check and try to get an actual oil pressure reading next week, and determine if i pursue a solution or start thinking about retiring this poor old truck.
