How to Reseat / Lap Valves (Basic Valve Job)

In this video i'm explaining how to reseat or lap valves in a flathead or overhead valve engine. Also can be called a valve job, but this is not a complete valve job. I also used to much valve grinding compound, it does not require a whole lot. Usually when a engine needs this done is when a engine has low compression that is found to be leaking around the valves, or sometimes a engine will backfire do to the valves not closing completely/properly. Thanks for watching.

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.





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.





5 Horsepower Briggs Restoration Project and How to unseize pistons and valves
May be a while on the rest, just hang in there, I will eventually work on this again, its just going to take alot of money to get it bored out and sleeved, new valves, new piston/rings, new rod, everything! i found an old 5 horsepower briggs and stratton engine block with a thrown rod, seized piston and valves. In this video i unseize the piston and valves, and remove them. And begin the clean up process. Cylinder might have to bored. Also note, i said on the video that i may need a new piston because of the stuck rings, not necessarily true, because the rings should come off with no problem. Unless the piston is scored or worn, it shouldn't need replaced. Thanks for watching, and please subscribe!





How to lap valves on a 1995 Eclipse Talon 420a head (non-turbo)
When my 1995 eclipse timing belt broke I knew that there was a 99% chance that the valves were bent in the process. I searched the internet for a good way to replace them, without having much luck. I figured I would try and come up with something myself, I figured I would document the whole process of valve lapping by video...hope this helps you if you are in the same bind as I was!!!

Compression Testing and What You Can Learn From It - EricTheCarGuy
Compression Testing and What You Can Learn From It - EricTheCarGuy Here is a video on performing a compression test on an engine to assess it's mechanical condition. An engines ability to compress air and fuel is directly proportional to it's performance since an engine is nothing more than an air compressor once you take away all the controls. A compression test is a good general test that will give you an idea of the engine's overall health but it does not give specific information on what the problem is should there be one, for that a "leak down test" would be required, here is a link to that video. http://www.youtube.com/watch?v=WgrfT0LFMhc However if you find yourself looking for the source of a performance problem with an engine, this is a great place to start. This test is often overlooked in favor of looking at the fuel or ignition system, I think that's a mistake, if an engine can't perform mechanically no amount of electronics will make that better.

Valve seal Replacement
Leaking valve seals cause your engine to smoke when you first start it up, and then it usually runs the rest of the day with no smoke. Usually replacing the valve seals will fix the problem. Here's how to do it. Of course other engines may vary to some degree but the basics are the same.

Briggs and Stratton Power Built 12.5 HP Flathead Model 28 Rebuild, Teardown / Reassembly PART 2
PART 2.... In this video i'm doing a teardown and rebuild of a Briggs and Stratton Power Built 12.5 HP Flathead Model 28 Lawn Mower engine. Hope this series helps you, be sure to watch the other parts. And the last part is the first start of this motor after being rebuilt (not a complete break in video, just the first few minutes of running and adjusting carburetor) The only thing i left out was checking the ring gap clearance, which all you do is put a new ring in the cylinder use the piston to push it down about a half inch or so and use a feeler gauge to check the gap on the ring. Use general safety rules when doing anything like this, it is extremely to cut/smash fingers at any point. I cut my thumb really bad on the timing gear on the crankshaft (off camera). Just be careful and use common sense. Thanks for watching
