Out of curiosity, why did the 2.5L get a timing chain tensioner and the 4.0L didn't? I'm not talking about that little rubber block on the left side of the timing cover.
my guess would be so that you can wind the 2.5 to the moon to make the jeep go.
But it is installed on the 2.5L, not the 4.0L. The 4.0 has that stupid rubber block that throws off the timing.I'd guess that the tensioner is there to quell the cam harmonics you can get at high rpm in the 4.0L engines-- nothing inherent to the 2.5L.
I don't see why it wouldn't hurt on any 4.0L. Especially when the chain stretches with age.It would probably be a good addition to any 4.0L that will see +5000rpm.

Whats red line on the 2.5L?I can only assume that no one figured you'd be spinning a station wagon engine to +5000???
Whats red line on the 2.5L?
...would ever make it past 4000 rpm without moving some of it's internal goodies to external locations:explosion
Lol.
One though it maybe the 2.5L valve train doesn't have enough mass to keep the chain taught under low RPM conditions.
