How does the oil travel from the Pan to the overhead cam?
How does the oil travel from the Pan to the overhead cam?
Oil travel from the pan to the overhead cam and heads on the 5. The oil also flows over the followers (rocker arms) when it flows out from the camshaft journals and the tappets then drains back to the oil pan. Oil also flows through the cylinder heads to the VCT solenoids through oil passages in the head.
How are solid lifters used on hydraulic cams?
Solid lifters on a hydraulic cam? This new trend in cam design is actually drifting over to cams made for hydraulic lifters, which eliminate the need for valve lash by using the engine’s oil pressure to maintain a constant contact between the rocker and valve tip, regardless of engine temperature.
When to replace lifters on an overhead cam engine?
If you find that the engine had bent pushrods, worn out lifters (or lash adjusters on an overhead-cam engine), damaged or worn out rocker arms (cam followers on an overhead cam engine) or worn out valvesprings, then you’ll need to replace the affected components.
When to use a tight-Lash camshaft in an engine?
“A tight-lash camshaft may permit the valve to initially accelerate and decelerate more quickly without being overly harsh, but may not be of practical use in situations where engine growth from cold to hot will require resetting the lash frequently,” says Knight, noting that engine materials play a critical role in such camshaft decisions.

What should the warpage be on an overhead cam cylinder head?
In an overhead cam (OHC) cylinder head, two surfaces that must be in alignment are the gasket sealing surface and the: camshaft journal bores. The maximum allowed warpage of the cylinder head gasket surface is typically: 0.003″ (0.0762 mm). The main benefit of using roller rocker arms in the valve train is: reduced friction and wear.
What kind of oil pan does a 4.0 SOHC use?
The 4.0 uses a unique 2-piece oil pan, the main body of the pan is cast aluminum and is internally stiffened. Furthermore, the oil pan is a structural member of the engine and acts as a girdle since it is through bolted into the main cap bolts.
Can a 4.0 SOHC engine drive a passenger side Cam?
These cams require a custom retainer, valve seal, and spring kit which is also available now. Since the 4.0 SOHC engine drives the passenger side cam from the rear of the engine, changing the cams with the engine in the car is going to be challenging.
