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.
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
How To Perform a Compression Test - 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.
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.

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!!!
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!
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
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.
Porsche 944 Timing Belt Failure BENT Valves
Porsche 944 Timing Belt Failure & subsequent results. Got a 944 Porsche
2.5lLiter 4 Cylinder. Unfortunately it has an interference head. Some
mechanics tried to "fix" it not knowing what "interference" means. They
replaced the timing belt and bent the valves even more. They gave up the
2nd time around. Good thing they never finished the job as it would not
have worked anyway.
Honda accord timing belt noise
UPDATE.-Timing belt has been loosend however noise still remains-------ive
had my timing belt replaced and now it seems to be making this strange sort
of noise around 1000rpm as you can see, do YOU think this is a serious
problem? leave us a comment and tell us what you think
Honda Accord idling problem
My 96 Honda Accord EX, with a VTEC engine has this idling thing going on
and I am unsure why. It's been doing that over a year or so, and a few
months ago the "CHECK ENGINE" light came on. The car was parked in the
garage, I had to let it roll out onto the drive way to get better lighting
for recording before I started the car. If anyone has any idea of why it is
doing it, please let me know in the comment section. Thanks!

Timing Belt - the Forgotten Belt. This video stresses the importance of
checking and following the manufacturers recommended replacement interval
for the timing belt. Along with recommendations to replace the "hardware"
associated with the Timing Belt (Tensioner, Water Pump, and Idler Pulleys)
at the same time the Timing Belt is being replaced. To find out more
