    Can I Fix Exhaust Manifold Leak With Thermosteel Or Another High-Temp Cement

    I have an exhaust manifold leak on one of my 2000 5.0 Explorers. I am nearly certain that the leak is coming from the exhaust manifold gasket. I really don't want to take the manifold off and risk breaking bolts or studs trying to get it apart. I've had enough trouble with bolts that are...

    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...

    Where is my coolant leak coming from?

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...
