    Hello everyone I have a 98 SOHC V6 in the UK and it is running very rough on cold start ups. I've replaced the PCV valve and the idle air control valve which did make a difference, albeit for the engine to rev quite high every time it's started hot or cold. Is there any suggestions on what I...

The vehicle was dry until I filled up the radiator so there is no extra pressure on the system and you can see where the water...

    EGR Valve Tube Leak

    My 2000 4.0 OHV has a leak in the EGR Valve Tube, it has been welded once, so repair is probably not a good option. I had a garage look at it, they are recommending replacing the LH Manifold, the tube, the EGR Valve, because everything is so fused together. One manifold stud is broken, they fear...

    Headers questions

    Is there a difference between the SOHC and OHV headers? I have a 98 explorer 4.0 OHV. It seems like when I find a place that has them online it specifies SOHC or it just say 4.0 kit. In addition, ranger headers? same difference, will they fit on an explorer?
