Well, I'm not up on SOHC/OHV block differences, but why wouldn't it work?
It's my understanding that the SOHC oil pan bolts to the OHV, so worst case you use an OHV block, SOHC oil pan/girdle and the Cossie DOHC heads and intake, right? Or are you talking about the chain difference where the Cossie uses two long chains and we use 3 shorter chains off the "Jack Shaft"? I think that actually works to our adavantage! We could modify the internals to use the Cossie 2 chain system and not have to fab/modify our timing cover... maybe...
Other than not being able to do the DOHC head swap in an afternoon with the 4.0L SOHC engine still in the mounts of your Explorer, What's wrong with that?
I think I'm missing something on the oil pump drive though. The cam has an opposite direction drive for the oil pump, OK, I got that. So what? Is there a reason the lobes can't be ground off the 4.0L OHV cam and use the 4.0L OHV factory oil pump/drive? I think the issue here is
vs.
, with Tobbe's inability to access to
parts.
Tobbe: What timing cover are you using and does it bolt up? There looks to be a CnC (2mm?) adapter beween the timing cover and the heads, can you confirm/elaborate? What oil pump are you using (Cossie, I assume) and why? Thanks!
