Angry What kind of noise does a stuck Valve Make ?

What kind of noise does a stuck Valve Make in a toyota 22R engine.

The engine does not always make the noise, once its starts you would think its ready to fall apart. Like someone going at it with a hammer.

My engine is making a loud banging noise, even at idle.

Its not the bearings, I have used plastigage and checked them.

Replaced the thrust washers when in the lower end.

New clutch/disc and machined flywheel.

Checked all the valve guides, rockers and springs also.

Suggestions

Do a compression check.
It's an intermittent noise? Cold/Hot?

WOW!! Mine started doing the same thing ...(22R) as well. I pulled the motor monday, then the head and voila!!! The head of a very small screw (from the butterfly flap of the carb???) was in the #3 head getting pounded by the piston!! I had shut the motor of immediately when it started knocking so all I got to do is clean it up and put on new head gaskets.

Ironic, my brother destroyed a 22r the same way. It was the head of the air housing stud (we think) that came off, fell in, and completely FUBARRED his engine.

That means 22R's must have had bolt-falling-in problems, right?

A stuck valve if it sticks open makes no noise, you just lose that cylinder, if it doesn't get stuck so far open that it's hitting the piston. Stuck closed, same thing, no power but no noise either. Check the rockers and everything on top first, start it with the valve cover off and see if you can find it, if not, take the head off.

Need more info.
Does it do it cold? hot? all the time or just part of the time?
Have you pulled the valve cover and looked?

I had a rocker arm retainer screw on a suzuki motor come loose, knock a rocker off of a valve and then travel through the oil system. Not much left of that one when I got back to the trailer.

The clattering was terrible. THe motor had about 30% power loss, but I drove it for 5-7 miles off road and about 10 miles on the road.

Valve train noise is a light click sound usually. Your louder bangs are pitson/rod/bearing issues.

My friend had one throw a rod through the block on a trail ride... it sounded like someone was hitting the bottom end with a hammer. We think it was a rod bearing.

Most likely a Rod Knock....if the large ends check good, its the small end. Or you could have really bad piston slap.
Either way its going to unless you fix it now.

It makes the noise not or cold.

Its so bad it cannot be warmed up.

It can stop making the noise all of a sudden for up to 100 miles this time.

Then all of a sudden it just starts up.

This time worse than ever !

Checked the lower end with plastigage and everything was ok.

Did you check the rod bearings too? You can tell if they are bad by just tapping on the caps.

Pull the valve cover and take a look at the cam retaining caps. There are no bearings in them and the have a tendancy to go boom. The one at the rear usually, closest to the firewall. It will make the same sound as a rod knocking......

Another possibility is the piston pin. When you get one that wears it sounds similar to a rod knock.

I had that EXACT same thing happen on an old Celica of mine. This was not a 22 though, newer Celica so entirely different motor.

Checked the mains and rods, replaced thrust washers while it was apart.

Sounds like a hammer on metal.

Pulled the plugs and fished around in the jugs with a magnet. This was done in each jug about 10 times after using the starter to rotate the engine.
No foreign objects were found. Also used one of those flex grabbers, nothing.

With the plugs out, it does not knock when turned with the starter.

As it was running, a crow bar was used on the motor mounts and the noise does not change.


A neighbor across the street can hear it in his garage.
