3/4 cylinders

[Halon]

Just take the head off.

+1.

Cylinder #3 has 0psi and a wierd looking spark plug, so something is obviously fucked up. I'd skip the bore scope and leak down test. The head pretty much has to come off at this point so just take it off and inspect for damage.

Now to leave the manifolds on or take them off? I've heard its easier to leave them on for a place to grab.

[mark4g63t]

Decided to leave them on. Going to start pulling it off after I make the tension tool. It's a 8mm x 1.25mm thread pitch and should be at least 8 inches long correct?

[asshanson]

Diameter and pitch sound right, not sure on length.

Took the head off and BAM a chunk of the exhaust valve on #3 is gone!:eek:

[mark4g63t]

What should my next step be? Think I should get new valve guides?

[goodhart]

Was that an exhaust valve? I would be trying to find that piece, get the head checked out, and check you turbo if that's an exhaust valve all for starters.

[Halon]

Take the head to a shop, have them fix it. Try to find the missing piece. Put it back together. Let r buck.

Is there any cylinder wall damage?

[mark4g63t]

No cylinder wall damage. Still have crosshatching in them. It was a #3 exhaust valve. Taking the o2 housing off now to put my external setup on and will see if there is damage to the wheel.
