Cylinder Head 102 - Hydro Test Valves
If you noticed a drop in compression on one cylinder, and pouring a cap of oil through the spark plug holes didn't fix it, then it's likely you experienced a leaky valve or a burnt valve seat. What this test does is show you where it was leaking. Typically it takes a valve job to repair, but this can also occur on a freshly-machined head if any work was done improperly or out-of-center. I'm using tap water for the test because both cylinder heads I'm testing will receive extensive machine work and cleaning before being re-used. If you were to do this test on a freshly-machined head, you'd want to use deionized water as it contains none of the salts (sodium, chlorine, etc...) that would leave deposits and corrode metal parts.





High Perfomance valve spring testing 10K RPM
PAC Racing Springs in-house dynamics testing, utilizing a high performance SpinTron tester. This video shows a Nascar style performance dual spring. This spring shows good dynamic behavior even at 10,000 RPMs. The visual analysis is a useful tool to detect dynamic behavior of valvetrain components at extreme engine RPMs.

PAC Racing Springs in-house dynamics testing, utilizing a high performance SpinTron tester. This video shows the performance of a single beehive spring is comparable to that of a dual spring in performance street applications. The visual analysis is a useful tool to detect dynamic behavior of valvetrain components at extreme engine RPMs.

Experimental Rotary Engines: Model 32
This follow-up to my previous videos summarizes the current design for the benefit of those that are experimenting with Model 30 based engines. Model 32 is not yet finished but most of the mechanics are in place. It's been dry run & tested for compression, friction & wear. Performance so far is superior to Model 30. Completing the control electronics & firmware will require more time. Model 32 is similar to Model 30 (previous videos) except that: the rotors are steel lined with graphite; the vanes pivot (rather than slide); vane engagement is electronically controlled; seals, accuracy & fit are improved; parts count & reciprocating masses are reduced; rotor phase angle is adjustable to provide expansion ratios approaching 30:1; compression ratios are adequate for burning vegetable/diesel oil using direct fuel injection; the Lexan cover is replaced by a dimensionally more stable aluminum reinforced plate glass. Fins will be routed into the exterior body as needed for cooling. I should finish evaluating Model 32 by fall '07. The next design (Model 33) inherits much from Model 32, except that it uses 1 rotor & 2 vanes. The purpose of this open source program is to develop more fuel efficient ICE's capable of operating on a variety of fuels for the benefit of our environment, our economy & our future. This material is offered freely in the hope that it may be useful & inspiring to tinkerers world-wide wishing to improve Internal Combustion Engine technology. -Dave





EASY, HOW I LAPP & GRIND VALVES. THEY DONT TEACH THIS TRICK IN SCHOOL, ONLY OLDSKOOL.
Automotive technician since 1991 I show how I do a valve grinding job (Lapping Valves) at home using a vacuum hose, drill & compound, don't over think it and don't assume it cant be done. learn how and save money on your project with out taking your cylinder head to the machine shop. Valve guides must be in good shape ( with no significant play or bent Valves before you perform this task, but this procedure works very well if done with care & quality. Go get it! and God bless.





Top Fuel Engines? Controlled Nukes
If anybody thinks it's magic to get 8,000 hp out of a top fuel engine...think again. It takes science, technology and a skilled tuner to make these thing run with exploding. The Chinese would love to have this technology, maybe they would blow themselves up. http://www.motorsportsunplugged.com





F1 Engine - Explained
How do F1 engines work? What are the differences between a Formula One engine and a normal car engine? In this video I give a basic overview of F1 engines, and talk about some of the things that separate them from your everyday daily driver's engine. One major difference is in the valvetrain, F1 engines have used pneumatic valves, which I will go over. NOTE: Volumetric efficiency of over 100% is possible in naturally aspirated engines, thought it is not necessarily common in everyday road cars.

Cylinder Head 105 - Valve Job Basics
Valves not sealing? Valves not bent? This is how you fix that problem. In this video I outline the basic valve job procedure. Cleaning the valves, cleaning the seats, cleaning the combustion chamber and lapping the valves in to make a better seal. Here I cover the process start-to-finish. It's the same exact process for pretty much all non-rotary combustion engines. It takes patience and perseverance to do this job, but anyone can do it. Reference your service manual for measurements and service limits. Everything else that's not in your service manual is in this video. I apologize for not having broken busted crap to work with in this video. It's more beneficial to all of you when bad fortune falls on me because it gets well documented, and many people watching these videos are looking for answers. If you have bent valves, you will discover it quickly once you chuck one up in the drill. You'll see the face of the valve wobble around while it spins. You'll see evidence of this damage on the valve seat. If it's bad, you may see damage on the valve guides in the form of cracks or missing pieces where the valve guides protrude through the head ports. Give all that stuff a good visual inspection. ...and if you doubt yourself, never hesitate to get a second opinion or consult a machine shop. They will have access to expensive tools that you wont find in your average gearhead's garage.
