Ever Seen This?

This came out of my 1990 Eagle Talon TSI AWD... thought it was a blown head gasket and turned out when I took the head off I saw this....

So you burnt an exhaust valve..big deal. drop some new ones in and your good to go.

Now a bunch of people are gonna post saying..,find the rest of the valve bla bla bla,your screwed bla bla bla..

Ive seen this happen on many cars.. replace the valve and get all the other little problems fixed too.

I agree mostly with Raph. I would however check your exhaust wheel of your turbo since that small part of your valve may have went out the exhaust manifold. You want to check your exhaust wheel to make sure there are no chips or cracks out of the blades. ( I rebuild turbos I have seen it happen.)

I had a turbo that wouldn't spool up. I pulled it apart and found out there were 3 pcs. of exhaust valve stuck in there. The former owner had been beating on it with a hammer to get it unstuck every so often.

Ralph is kinda right, but the other part of the valve has gone somewhere, why not try and find it while you've got everything apart? The worst that happens is that you've wasted 30 min pulling your turbo apart and you know for sure that nothing is in there. You can use it as an excuse to port it as well. If you do find it in there, you'll have saved yourself headaches later on.

xi Talon ix, watch your mouth. Warning handed out. Don't slip up like that again.

If you are incapable of reading the rules, call me and I'll read them to you.

I would also check the cyclinder walls for scarring. This can increase the rate of engine fatigue. You can drop the oil pan to see if there is any bits in there as well. I've done this before. And found a small brass ball. I assume it was from an oil squirter.

The piece didn't break off, it melted. It even melted part of the stem. The guy I took the head to has been doing heads for years and has never seen anything like what I brought him. I'm still gonna check for that piece but I'm not as worried about it now that I know it melted.

The problem with it melting is metal does not evaporate. Odds are it got very very hot (melting point) and broke off. With the constant leak it will burn the valve stem. I dropped a valve on a N/A motor once because of a bad leak on the exhaust manifold. It did take awhile but finally melted the stem enough to drop the valve.
