5 weeks in on the bad gead gasket and the dealer got the head back from the machine shop yesterday. They tried to put it on this morning and couldnt get it to torque down right. Turns out the shop took too much off the head. Time to order a new head. Be in next Wednesday. So my wife decided to just trade for another one. Got a hybrid touring this time. Ext warranty and the other shop covered all the cost on the other one. Roughly $9600
Sometimes you just have to cut your losses and move forward. Folks got to get to work and live their lives. It doesn’t make sense to leave a vehicle in the shop forever.
Sounds unlikely. Service limits for a cylinder head are so tight for modern engines that any warpage makes the cylinder head unserviceable, a machine shop would know this.
Service writers are not trained in engine repair and often do a poor job of explaining the repair process.
With an extended warranty the provider will schedule an inspection for the original estimate and for the revised estimate, takes time. Probably two weeks for the original approval, then another week for the technician to find time to remove the cylinder head, then a week at the machine shop waiting for inspection.

Wow, you seem to know every thing. Third day in the shop i stopped by and they showed me the gasket and the engine.
Machine shop took off 5 thousandth and the limit was 3 thousandth.
Bottom line is they allowed more in trade for it than we expected and now its theirs.
On a side note, these ads really stink. You cant see what youre typing
I find this all very difficult to believe, although since the vehicle is gone it’s a moot point. While I don’t doubt that Honda specifies .003" as the published spec, it is ludicrous to suggest that the engine won’t go back together properly, or run well if more than that is milled off. And a difference of just .002" is not going to make the head bolts “bottom out” in the engine block, preventing proper torque.
I remember a thread here about a Toyota Prius engine which supposedly requires a new cylinder head anytime the engine is disassembled (no resurfacing allowed), and yet there are many people online who say that they had the head resurfaced, and the engine runs fine and does not consume oil or coolant.

Yes, the ads are incredibly bothersome and problematic on this platform. It makes typing and reading discouraging.
I have had my lengthy post abruptly disappeared while typing due to the ads and I had to figure how to retrieve the disappearing thread afterwards. It usually ends up in draft.
As has been discussed previously–at length–using a different browser can eliminate that problem. As a result of the problem that you mentioned, I no longer use Chrome when posting to this site, and I have switched to Duck Duck Go.
No problema with DDG!

As @VDCdriver mentioned, use the DuckDuckGo browser. It not only eliminates ads, it erases your history whenever you close the application. I’ve used it for a couple of years and I’m very happy with it.

I tend to agree, it sounds like someone was reusing TTY bolts, cause even if a regular bolt bottoms out, it will still take a torque, even a cross threaded bolt will torque, they just won’t have proper clamping force, or the head gasket material will keep crushing making it feel like the bolts are not taken/holden proper torque…
Or they didn’t chase the threads in the block, or something..
I will have to think on this one some more, I might be missing something..
And YES DDG == NO MORE ADDS!!!
I went to DDG for this forum only last September and have NOT seen one add since… WooHoo!!!
I am using Firefox and adblock+. Is there a downside to using an ad blocker that I don/t know about?

I don’t believe there was an attempt to install the old cylinder head, just a service writer trying to explain something that was not properly explained to him. The report from the machine shop indicated that the head could not be resurfaced within the service limits, therefore the cylinder head should be replaced. At that point it is up to the technician/shop. The warranty provider is going to pay for a proper repair.
Cylinder head resurfacing on modern engines is very limited due to vehicle emissions standards. Removing cylinder head or block material changes the valve timing. This is an Atkinson-cycle engine, valve timing is very important. When the camshaft is 0.10" closer to the crankshaft than it should be, the timing chain is too long. This retards the valve timing. The compression ratio also increases. Valve-to-piston clearance is also a consideration.
A new cylinder head is $2640, but high-tech engines save fuel.

You paid for extended warranty and got zip? Dang.
What year was this vehicle?
He received a $9600 engine repair.
Post #1 says new head will arrive next wed, it’s not fixed today 07/14. So your repair is not done and you are trading it in. Dealer is giving you xxx dollars as trade in. Is trade in value less than what you think it is worth, retail? Seems to me getting trade value is a losing proposition.
Kennady said they got more tradein then they expected, have another vehicle so more discussion is a waste of time.

Car is at dealer awaiting lengthy repair.
Only costs me time.
So I will buy new car to move on.
Which ain’t cheap.
But, it’s new.
The service department will get paid via service contract to repair the vehicle, the sales department will sell the vehicle. No loss of value.
I am well aware of what the manufacturer specifies as the resurfacing “service limit”. But the real question is how much can you actually get away with, and still have an engine which runs properly and does not consume oil or coolant? Just like with the Prius engine which says “no resurfacing allowed”, there’s obviously a certain amount which can be removed, if necessary. And there’s obviously quite a difference between 0.003 (three thousandths) and 0.1 (one tenth).
That combo has been working for me, for years.
I think .010" could be removed without problems. I don’t see any correlation between resurfacing the cylinder head and oil or coolant consumption, it is a modification that affects emissions output.
Some of these engines have a compression ratio of 14:1, resurfacing the cylinder head can affect the results of the EPA Federal Test Procedure.
