I have a 2000 xls 4 door 4wd with the 4.0 ohv i bought the truck used with
63k miles on it the motor had 30k it now has 93k miles when i start it up
the motor seems to very loud more when it's cold out when it warms up it
gets quieter but stills seems a little loud some time it sounds like a
diesel i know this is a common problem with the sohc witch is why i looked
for a ohv any ideas on what could be the problem would be great thanks

Techron is what chevron puts in its gas, its also sold in bottles.

Its 1 of the additives for fuel that actually works.

You can purchase them at CostCo. They are actually relatively cheap in
price.

If the "loud" sound is under the hood, it could be a bad hydrostatic fan
