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.





Diagnosing the Engine Knock
Trying to figure out what the engine noise is. Looks like lifters that won't drain down plus maybe some plugged up oil squirters.





Honda Accord Valve Adjustment - EricTheCarGuy
This one was a request from a couple of viewers, I like to keep you all happy so here you go. This video is actually taken from a larger video I call "Accord Smackdown", in it I replace the timing belt, radiator, a major service, and some other stuff that I don't remember. I think there will be a couple more videos from this "smackdown" in the future, there is some good stuff in there that I think you will like and possibly learn from. If you have other topics you would like covered don't hesitate to let me know, I'm happy to give you what you want. Post them as text or video responses to this or any of my videos. I'm going to get the part number for the tool I used in the video sometime next week and post it here so keep your socks on and check back sometime next week.

How to fix bad lifter knock / tick / noise EASY
This is a video on how I fixed the lifter knock on my 2001 Mustang V6. *This worked for me. IT WILL NOT WORK 100% OF THE TIME* I'm not responsible if you manage to screw up your vehicle doing this. DO IT AT YOUR OWN RISK!





Detonation Knocking Pinging - What is it
Every wonder what that metallic rattling is coming from your engine or that your car sounds like it is dragging a chain behind it. Well, that is called detonation or knocking or pinging depending on when you were born and where you are from. In this video we will go inside the cylinders and find out what's really going on.





1994 Honda Accord w/ Bent Valve
A video illustrating how your 94 Accord's engine will probably sound if it has a bent valve. Bent valves often happen in cars containing intereference engines, such as this particular model of Honda. They occur most often when the timing belt breaks during operation of the engine. This is an expensive repair, requiring the engine head to be dismanted. To avert this disaster, change your timing belt every 90k miles or sooner. This particular car had about 178k miles on it at the time of the video. There was a bent valve in cylinder 2, and the cylinder lost all compression.





HELP! Engine Knocking Noise 3800 Series II
Can anyone confirm this noise? Happened after a 2 hour highway trip. Oil and Filter change the day before, and Lower Intake Manifold Gasket replaced about a week prior. It did at one point seize the engine, however a couple of days later it turned over with plugs removed, and fired up fine right after they were placed back in. Still making this same noise, as it did before it locked up. 240,000 KM on the car and engine.





5th Gen Honda Prelude Whining Noise, Oil pump?
My 98 Honda Prelude... My car started to give me the Oil Flickering Light Every time I would come to a stop sign or stop light or while idle. Revving the engine made the light go away but as soon as i came to a stop it flickered back on rapidly. The oil while fine on the dip stick.... i changed oil to make sure of everything, even filter. Problem got worse, after a day the light came back flickering but it brought along a hard whining noise that you hear now in this video COULD IT BE THE OIL PUMP GIVING OUT???? The Noise is not coming from any Power Steering, Any Pully, Timing Belt or Belt Tension. I Jacked up the car And Started hearing the noise coming within the Oil Pan! WTF! What do you guys think it is at your 100% positivity. Oil Pump Goes For nearly 200 bills, so before buying something that it could't be I'd like your Opinions. TY!





Last video before I sell it. Engine knocking noise
subaru impreza EJ20 engine, varying knocking noise. Most prevelant at top of pass side cylinder head above cylinder one. Noise comes and goes some days. Oil pressure was at 30psi during this video. I dont have any place to diagnose this noise so am forced to sell it for stupid cheap, which is killing me. if anyone has any insight, please LMK. BTW drained oil after noise appeared, no excessive bearing material/metal material found. car has been driven 500+ miles since noise appeared, no issues with running. Noise appeared one day right after startup. this is the for sale ad for anyone interested. http://orlando.craigslist.org/cto/1189733480.html





First Impressions of my Honda Prelude.
