But one thing you can do we have the exhaust side here on the other side.
We have the intake side to kind of do a quick check to see if your valves might be bent go ahead loosen up all the the valve lashes lash. All the valves on the springs. Just a 10mm bolt and then you are able to be able to move the valve up and down.
So you loosen up all those right and then i get to one that ive loosened up and its not moving this one is not moving this one is not moving. Well go on the other side on the intake side got movement. There movement.
There can you guys see that movement. There movement there there and there. I dont have movement on this side or this one.
So. While the head is still in the vehicle go ahead and loosen up all your valves or loosen up all the valve lash. So all these moved except for these 2 right here.

That were not letting us move at all so it was these. 2. That were not moving at all and as you can see right there.
This should be closed. This valve should be closed cause. I took off all the lash on the valve on the top side and this valve should be closed as well.
But you can see that its not it is bent all the other ones are closed. This one isnt and this one isnt. So these valves are bent.
So that is a quick and easy way to find out if any of your valves are bent. If you have a timing belt break or you suspect that you have bent a valve be that the timing belt breaks or something else catastrophic else happens. So i just wanted to let you guys know how to look for a bent valve.

Need to pull the head off and do im going to have this send out have the valves checked have it resurfaced so while i was editing this video. I thought about one thing even if you take all the valve lash off the spring and release all the tension on the spring.

Allowing you to move the it up and down even though it might move up and down. There is a chance that the valve can be bent still and when i say bent. Im talking microscopic you cant even see it with the naked eye.
What you have to do is put it on a special machine that they use to resurface valves. When they are doing head work. And when you start spinning the valve fast.
Enough you can actually see a wobble at the end. Its very slight and minute. But at a high speed turn when there turning the valve to resurface.
It thats when you can see it so. Even. Though you might not have a situation as bad as i did here where the valve wont even let go anymore.
Its still tight and then when i flip the head over you can actaully. See that the valve is actually bent because its staying open and not seating correctly on the back side of the head on the bottom side of the head. You can still have a bent valve even though you might not be able to see it so i could have valves that are bent.
Because the pistons hit the valves and even though in the video. It looks like all of them are closed and sealing correctly that might not be the case.

So what happens on a valve as the engine is turning as the rpms and the engine is moving and turning that valve actually spins 360 degrees inside that inside that seat every time it opens and closes. It actually moves a little bit that valve done not stay stationary. It actually rotates so as that valve starts rotating and it gets to the spot where its bent a little bit you might experience a misfire so i just wanted to disclose that to you guys just in case.
You do this work here and you dont. See any obvious signs of a bent valve you still might have a bent valve so if you plan on keeping the vehicle. Its a good idea to have the head checked or if your just if your trying to get the timing belt back on to get the car running and your going to sell it then you might even want to mess with it leave it for the next guy to deal with.
But i just wanted to disclose that fact alright looking at anywhere between 150 to 250 bucks to get it done. And then you have to do the head gasket and all that other good stuff. So.
If you guys want a quick and easy way to see if a valve is bent go ahead loosen up all the valve lash take all the pressure off the valve and see if see if it will move at all and if it doesn.t most likely 999. That you have a bent valve alright.
