4.0 SOHC history/family/heritage?

Can someone here explain the 4.0 SOHC engine or link to another post here that does? Is it "modular" like the 4.6 and 5.4? Ford of Germany like the 2.6, 2.8, 2.9 and old 4.0? Is it based somewhat on the 3.0 Vulcan or some other engine? Common belhousing pattern with any other Ford engine?

Also, what are the basic facts about this engine. 60 or 90 degree? Balance shaft? Belt or chain cam drive? Roller and/or hydraulic cam followers? Any other interesting engineering features?

I am looking at the new Mustang and would like to know about the V-6 engine. Mustang brochures, website and stupid dealer salesmen do not have the information. Im sure the good members of FTE do.

Jim

I'll try to get you going Jim.

The 4.0L SOHC is a completely different animal than the 4.0L pushrod OHV. The only thing they have in common is where they are/were built (Cologne). The SOHC also has no connection to the 3.0L vulcan or duratec engines. The SOHC has been used in the Explorer since 1997 and in the Ranger since 2001.

The SOHC timing assembly is chain driven and employs a jackshaft to drive the cams (i.e., the crank turns a jackshaft by virtue of a chain, and the jackshaft turns the camshafts, also by virtue of chains).

The 4.0L SOHC engine consists of the following:

- single overhead camshafts
- sequential multiport fuel injection (SFI)
- distributorless ignition system (EDIS)
- aluminum cylinder heads
- cast iron, 60-degree V cylinder block
- balance shaft (4x4 vehicles)
- jackshaft
- unique engine timing configuration

FWIW, there had been some issues with the SOHC timing chain guides and/or tensioners. My information is that Ford has remedied this problem and there is now even an upgraded "kit" available for those already on the road that might need it.

HTH, good luck with your research.

AG4.0 is gaining momentum as a positive member of FTE.
I was under the impression that the SOHC 4.0 was derived from the Pushrod versoin. They both have the same bore and stroke. I don't really know for sure, that's just what I had heard from other FTE members.

The 4.0L SOHC is based on the 4.0L pushrod. Same bore & stroke. I do not know if they use the same block or not, however it is based on the same engine family. See here.
