How can you tell if a Taurus - Sable has a 12 valve OHC or the 24 valve DOHC engine?
if the spark plug wires go down the middle of the valve cover, it is DOHC. The Intake Manifold will also say Duratec. The OHV motor will have the spark plug wires connecting on the bottom of the head near the exhaust manifolds.
Where is the idle control valve on a ford explorer?
The idle air control (IAC) valve on my 4.0 L OHV is on the driver's side of the engine mounted on the side of the upper "plastic" intake manifold. Removing the valve and CLEANING it does wonders for its operation ability.
How do you replace push rod in a lawn mower?
Most lawn mowers do not use a push rod to open and close the valves as the end of the valve stem sits directly on a cam. The cam of the camshaft opens and closes the intake and exhaust valves. This is called an Overhead Valve or OHV. IF a large, old engine does use push rods, apply the same methods as used in an auto or motorcycle engine,: Namely, remove the valve cover and then the valve train. Each valve has a push rod in an opening underneath each valve rockerarm.
Who manufactures the OHV 208cc engines?
OHV stands for over head valve. It's not a brand name.
If one end of the vacuum hose on your 2001 Taurus 3.0 ohv is connected to the back of the intake manifold what does the other end of the hose connect to?
A reservoir tank with a one way vac. valve inline and connected to the heat control valve.
Where is the schrader valve on a 94 ford explorer?
If it's like my 1995 4.0 L OHV , I believe the schrader valve for checking your fuel pressure can be seen looking from the passenger side of the engine . It is on the fuel rail , which is installed between your lower and upper intake manifold sections , about the center of the fuel rail I concur. This is the same location as on my 1998 4.0L OHV.
Where is the EGR valve located on a 1993 ford explorer sport 4 liter OHV?
On the 4.0 L OHV engine, the EGR valve is located on the driver's side of the engine. how do i repair it
How do you find the valve covers or the rubber grommets where the PCV valve go on a 97 Chevy cavalier?
if you have an OHV the valve cover is on the top with about eight 8 mm bolts. The pcv valve is located on passenger rear side of valve cover with a hose leading into the intake manifold and big black plastic nut. if you have OHC or DOHC I can't help.

In regard to engines ohv stands for?
over-head valve(s)
In which one of the following four-stroke cylinder arrangements will the intake and exhaust valves open downward into the combustion chamber?
In the I-type cylinder head, the intake and exhaust valves are positionedvertically at the top of the cylinder head. Both valves move down into thecombustion chamber to open. This type of cylinder head is used in overheadvalve (OHV) engines, which are found most often in automobiles.ANSWERS: I-type
What is the difference between a cylinder head and a head gasket?
The cylinder head is a smaller block that (generally) sits on the top of the crankcase. It is the part of the engine where air is received and mixed with fuel, then passed into the block for the intake/compression/combustion cycle and then directs it out on the exhaust cycle. On OHC/OHV (OverHead Cam/OverHead Valve) engines, the cylinder head contains, at least, - with many more possibilities - the intake and exhaust valves (one or more of each per cylinder), the camshaft(s), either a belt or chain for timing the cams and valves to the movement of the pistons, fuel injectors (if present), and various types of apparatus to operate the opening and closing of the valves including mechanical or hydraulic systems for valve movement and sensors such as a MAF (Mass Air Flow), PCV (Portioning Control Valve), and/or EGR (Exhaust Gas Recirculation) valve. The head gasket is the gasket that goes between the cylinder head and the crankcase or block of the engine.
