How To Diagnose An Engine Knock.MP4
Engine noises aren't to hard to diagnose if you follow a few steps.





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.





H22a4 Bent Exhaust Valves
"The Incident" Just to clear up a few misconceptions, this is the sound of cylinder #2 bent Exhaust and intake valves. Not rod bearings, rod knock, or anything else. I paid to have the head rebuilt with all new valves, seats, springs, and retainers. It sounds the way it does because a piece of a broken drill bit wedged itself in between my Exhaust valves and seat. It runs perfect now and I've put 13,000 miles on it since.





Honda Valve Adjustment
Honda valves need to be adjusted on a regular interval and/or when they begin to make noise. Here is how you do it.





Testing for Leaking/Bent Valves
--Please Read-- :) Some of the best advice I can offer you about fixing your car is to search for an online forum related to your car, or even for your specific engine. If you have a popular car or engine, this can be an amazing tool in diagnosing and fixing cars yourself! -------------------------------------------------------------- Directions 1. Get kerosene, gasoline, or break cleaner. 2. Tilt head on its side, with the ports of the valves you're testing pointing up and exposed. 3. Fill the intake or Exhaust ports with the liquid you chose, make sure to use enough liquid to cover the back of the valve head completely inside the port. 4. Look at the valve surface in the combustion chamber for leakage. (Let it sit for several minutes) 5. If there is a leak, you could have a bent valve or just a bad seal of the valve to the head. You might have to replace the valve, or just use some lapping compound to lap the valve/seat to resurface. 6. Repeat for the other side if you wish. 7. This is a great time to replace valve seals if you have noticed they are worn too much. 8. If you have any questions, please post them here and I'll try to answer them quickly. -------------------------------------------------------------- You just tilt the head on one side or the other depending whether you want to test the intake or Exhaust valves. I'm testing the intake valves in this video. I did this way because I didn't have the leakdown test equipment, but also because I wanted to replace my head gasket anyway. I wouldn't say this is the best way to test initially if you suspect leaking or bent valves because it requires you remove the head. Try just a regular leakdown test first. But if you're taking it off anyway it's pretty nifty and doesn't require the leakdown test tools. There are several methods to do this, this is just the one I chose in my situation.

LOUDEST HONDA ENGINE KNOCK EVER!!!!!!!

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.





Honda Prelude H22 engine noise.mp4
I'm trying to figure out what is so noisy about my H22. Compression is perfect, valves have been recently adjusted, does not burn too much synthetic oil (maybe 1 litre every 2000km). But when the engine is cold it just sounds very noisy. Are my valves just loud, do I have piston slap or rod knock?





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!

Gsr b18c1 bent valve or need valve adjustment?
After a short pull from 60-90 mph my car starting bogging. 1. i thought it was the spark plug so i swapped it out. ran better but still shitty as hell. 2. Checked timing when i got home, it was about a tooth or two off. I'm sure it jumped timing 3. re-did my timing, now it runs better but still has misfire revving pass 3k. 4. its also making noises that wasn't there before, not sure if it's a sign for bent valve or need valve adjustments? any help would be appreciated. 5. also, while it warmed up, i took out spark plug #4 and it was boggin like it wants to die, also with #3, while #2, and #1 didn't do anything? i did research and it says if nothing it could be signs of bent valve? lmk.





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.
