Does anyone have any empirical data about the benefits of putting oil drain holes in the side of a tappet body in an attempt to improve camshaft/tappet face lubrication?
This is for an OHV engine with a pushrod valvetrain. The tappets do not have pressurized oil feeds, they only receive...
What is the best method to lighten gears in production gearboxes? Drilling out material somewhere inbetween the shaft bore and the gear teeth? Cutting a groove along the same radius?
Any ideas, or concrete information / advise, would be appreciated.
Is it necessary, or even a good idea, to apply a minimal load to clutch release bearings of the ball bearing variety?
Load would be induced by something like a 25# spring acting on the clutch lever (in the bellhousing).
Thanks.
What are the ideal oil pressures, or a way to calculate the ideal pressure, at particular points in the lubrication system? For example, what kind of pressure would be ideal for the rod bearings and main bearings?
I ask this because I recently read some information that reinforces what I...

Any idea what the mushroom shaped "pad" in the center of the piston i for? My first guess would be for a Saab style Spark-to-Piston setup, but it seems awful wide for this purpose. Any better guesses would be appreciated.

I did not find anything in the archives, so I have to ask this rather simplistic question:
Is drivetrain loss a linear loss as engine power increases or rather a constant that does not change for a particular drivetrain combination?
With that generalization out of the way, does anyone know...
In my search to find a solution for rust prevention on my classic cars, I saw this product featured on a television show in which they were setting up a pickup truck for plowing. The product is called CounterAct and claims a wide range of acknowledgements about its potential. However, I can't...
With the current focus on economy cars, both hybrids and high efficiency IC motors... why is there such a lack of focus on V-twin and (especially) V-4 motors in the auto industry? Of course, these are two engine configurations also missing from the Bosch Auto Bible.
What I'm hoping will...
Is it possible to repair the splines on a mainshaft rather than replacing the mainshaft? The state of the mainshaft is generally good, one of the output splines has a spot of corrosion which covers roughly 5% of that single spline and is about .5mm deep.
The question arises as new mainshafts...
Are there any decent, thorougly explained guides to combustion chamber and cylinder head design?
The recent discussion on the Chrysler Viper and 2.2L heads was very interesting, but obviously (to me), it is difficult to carry over recommendations for one head to another head of different...
