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.





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 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?





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.

Is this a bad tensioner sound?
I've had this car for about 7 months or so. I've had this sound secondary sound start coming from my engine. Anyone know what it might be?





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.

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.

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!
