The exhaust manifold on the 3.0 liter engine often warps and cracks, breaking off the studs between the cylinder head and the exhaust manifold.   The noise may be most noticeable when the engine is cold.


Regular maintenance is recommended to avoid timing chain failure. Rattles may develop in higher mileage vehicles. Regular oil changes will help reduce the incidence of this problem.

My 1993 D21 just turned over 244000 miles & still runs strong. Only repairs done (other than regular upkeep)replace the idler arm @ 243000 & a rusted out fuel tank. (very hard to find a "good" used tank.) The oil has been changed every 2000-3000 miles & a clutch last year. Takes a lickin' & Keeps on tickin'!

i have a 93 hardbody and everything on it is still stock and it has 245,498 miles on it and it still runs great

This truck took an amazing amount of punishment from me. I did have issues with the peeling clear coat. The manual transmission crunched in 2nd gear, and there would be a false check engine light that would come on periodically for no real reason. Other than that I was impressed with the amount of abuse the truck took and kept on going.
