Two questions...

Two questions...
Yea, I'm a recent Ford Ranger owner. I've been going over my truck with a fine tooth comb - I've replaced the PCV valve, air filter, fuel filter, spark plugs, plug wires, fresh oil change, transmission service. So far so good.
I've noticed that the DPFE sensor is disconnected... I can't find the connector anywhere... And the computer thinks everything is fine! (?) It did pass a smog test, but I am a bit concerned. Is this something I should be worried about (esp given I live where they love to do e-tests)?
The other thing I discovered is that I have a small coolant leak on the drivers side of the truck. I traced it as far as I could go, but I'm not overly familiar with the 4.0L motor at all... Uhh, too many GM car's over the years. But as far as I can tell, it's running down the back of the motor from under the head, onto the trans bell housing, and then onto the ground. It's a small leak, but I'm wondering if there's a coolant passage in the intake manifold in that area...if so, then maybe it's time I renew the manifold gaskets.

Yup, it's a 4.0L OHV. I'll replace the manifold gasket's... That will give me a chance to inspect everything. The truck does have an EGR and it is hooked up, but the DPFE electrical clearly isn't. Hopefully when I pull the manifold I'll be able to locate the plug and get it plugged in, though I'm still confused why that hasn't set off an EGR code in the computer.

Yea, I just got a complete intake gasket set - Victor Reinz. And in there was some notes that the rear water jackets for the manifold are plugged internally on the heads (1997 through 2000)... So, I won't be digging into this yet - I'll get the exhaust manifold and head gaskets because now it's looking like I'm pulling the heads. I really *HOPE* it's just a freeze plug or head gasket and not a cracked head...

Okay, the coolant problem was just the lower intake gaskets. I can't belive how toast the seals where around the cooling jackets. I've installed good Victor Reinz gaskets - no more leaks now, and hopefully it stay's like that for a good long time.
As for the EGR system, it has been totally bypassed. The connector for the DPFE was cut out of the wiring harness. Unless it becomes a problem, I'm just going to leave the EGR system as it is.
