made a mistake with valves

[jhunfiyell]

i realized that exhaust and intake valves are different in sizes. is that true? i just randomly just put it in, i thought they were all the same sizes.... what can go wrong? aww man

 

[BogusSVO]

Yep they are diffrent sizes, the intake will be the larger ones.

What will happen if you put them on the wrong seat.... your compression will be down if you install the exhaust valve on the intake seat

The intake valve will not seal on the exhaust seat

You're going to need to remove the head and reinstall them. Sorry

I just rebuilt my head in my car as well, to be honest even though they are different sizes I don't think you would switched them around. It shouldve been to noticeable if you did.

 

[Colt4G63 also]

Other than filthiness, and lapping compound left all over everything, they looked fine in the other thread you made about this. What happened?

I'm sure you would of noticed something was wrong... They are two diff sizes, and wouldn't seat right and if you put the head on and turned the crank by hand a couple of times im sure a valve would of hit a piston or something

Hope he didn't try and run it already

IIRC, if you're reusing the same valves, you should put them back in the exact same hole they came out of.
