Follow up to Oil on threads of 7-8 plugs. Intake removed. Valve issue? Help

[techinspector1]

If the gasket was compressed all the way around the ports and all the ports look the same, then you have no choice but to look at the guide seals as the culprits. I don't know what you discussed with the fellow(s) who put the heads together, but if you told them to check the valve to guide clearance, replace as necessary and install positive seals, then they dropped the ball in my opinion. If you did not tell them what to do to the heads, then it's probably all on you. They cannot be expected to do work that you did not authorize.

Now, if you did authorize checking the valves and valve guides and replacing as necessary and installing positive seals and they did that work, then somebody at the shop either installed the seals incorrectly or damaged the seals on installation or screwed the pooch by leaving excessive clearance between the valves and guides and you have a legitimate beef with the shop. Did you have this work done in writing and signed off on it?

I think what I would do is to pull the head and call the shop, making an appointment to take the head down there and have one of the guys take it apart while you stand there and watch, then inspect the whole mess and talk to the owner before you go any farther.

Would it be safe to say at this point in the break in that if the other plugs are not showing any signs of oil on their threads that I should just take off the head in question and have the issue addressed that is currently happening on 7 and 8 valves? I guess this is my fault as I gave the shop the heads and told them to check them out, fix any problems and so $350.00 later I thought that they would have taken care of what needed to be done. When they had them and called me they stated that 2 exhaust valves needed to be replaced but everything else looked fine. I am new to this level of work on an engine so I might have not been specific enough.

Based on what you've said about your instructions, and the fact that you now have a problem on one head if it were mine I'd pull both heads and take them back to the shop, have them concentrate on the known problem first, and then decide if they maybe need to go through the other one, too. It would be sad to put it all back together after having had one head done, only to have the other side start smoking....
