During return from vacation.......
About 120 miles into my 840 mile trip home I encounter piston slap, bad. I could hear it ever so slightly before, but now it's overwhelming when the engine is at a steady rpm above idle speed and when its first started. You can hear it a bit when it's idling also.
This thing absolutley struggled towing my 7680lb TT on the way back home. I averaged 7.2mpg heading south and then 5.9mpg coming home, nothing changed in driving or the load. I also noticed a small amount of smoke at idle when stopped at rest areas. It used a quart of oil in 800 miles.
How much longer do you anticipate this engine will last? Will it just continue to lose compression until it just wont run anymore or will the end be more "violent"?

Sounds like you need to run a compression check and see if it's actually a piston going south on you. How many miles on the motor? It could be host of other things wrong and the motor still be good.

It does not sound like a cam follower, exhaust leak, spark-knock or even a bent or burned valve. I'm 100% sure its piston slap. The truck has had a hard life, towed 7k to 11k often and has close to 160k on it now. I will go ahead and do a compression check but I'm sure it'll come out fine.
I've encountered plenty of engines before that had relatively good compression with piston slap before, it's the piston skirt that wears out and being these engines have small skirts, they are more suceptable to slap.

Yeah, I think I'm stuck when it comes to a choice of engines though. I thought about repowering with a cummins but that requires too much money. The amount of things you have to change is rediculous and I'm not willing to spend that much.
So, now I'm on the prowl for a 2002-2004 PI headed V10 that's a drop-in I guess.
EDIT: After futher inspection, turns out I'm hearing rod knock, on several cylinders. Guess I wasn't a 100% sure.....

Well, I found the problem and it looks like I'm in luck. This is really weird so read carefully.
I pulled the RH Valve cover and did a compression check. #1 thru #5 were slightly low in comparison to the LH side. I then applied air pressure to the cylinders one at a time with the valves closed and I saw the cam move but the chain did not. Looks like my timing chain is stretched real bad or the cam gears are worn out and the noise I'm hearing is the chain tensioner extended to it's max or the slack in the chain riding on the cam gear.
Pretty strange eh?

Timing chains, tensior, cam gears, and gaskets are cheaper then a complete over haul (or reman engine) so that's a good find.
I thought the timing chains would go more like 200K or longer before being replaced but you never know.
