Question ohc/sohc

I recently bought a 1999 ford explorer sport. It comes with the v6 sohc engine, while going thru the owners manual I notice there is also a v6 ohc. What's the diferece between this two engines?

they're the same engine. overhead cam/single overhead cam. the other 4.0L is a pushrod/overhead valve engine.

Other than both being V6 4.0s, they are not the same engine...


4.0L V6 OHV / 4.0L V6 SOHC
Horsepower 160 / 205
Torque 220 / 240
Displacement 4025 / 4015
Bore x Stroke 3.95 x 3.32 / 3.95 x 3.32
Compression Ratio 9 / 9.7

0-60 Acceleration
4.0L OHV V6 10.5 sec
4.0L SOHC V6 8.1 sec

That is for your modle year (1999)

Neither are most of the SOHC owners... I have 72,000 trouble free miles on my SOHC.

Opera House Works, What kind of cries are you hearing about from the timing chain. I have a 1992 explorer that I just bought 2 months ago w/165,000 miles. Is there a possibility of timing chain problems

Your fine, the SOHC didn't come out till '97 and as with every new engine it had recalls. If you actually add them up, the OHC had more recalls in its first 7 years than the SOHC has had.
