I appreciate the comment on timing chains versus belts and will research that the next time I buy a car. In this case the shims were underneath the buckets and were pressed against the valve stems by the buckets. Not performed because I thought this was included. I have seen an entire engine carried through a junk yard by a fork lift holding on only by the timing belt. I have checked the valve clearances in my 1999 Honda Civic about every 30,000 miles or so. Most modern engines are interference engines, meaning that open valves will be smashed by a closed piston.
I figured that if I want to get to 200k at 124 now then one or more of those things would go, so why not avoid the hassle. For comparison, I have a Corolla with 200K miles and I recently checked the valve clearance and it remains within specs, never had to make any valve adjustment on it yet. An interference engine is one that has insufficient clearance between the valves and pistons if the cam stops turning due to a broken timing belt. The mechanic then caused it to slide down into the engine oil pan. Just because this is on topic I'll post this here.

Going to just keep changing oil more frequently. If your engine is running rough and the spark plugs were corroded like that it could be that it's worn out. Greased liberally with silicon grease. The owners manual said it's a transmission problem when it blinks. Original part began to separate from base unit. I'm not hitting the mileage indicators but I do worry about heat stress on the belts. I am now going to take my 2004 Honda Pilot to another Honda dealership and am hoping for the best.
Especially coming back from the drag strip with big block Chrysler - ah the days when you had lots of room under the hood. I know its not exact as yourlooking for but it gives you a ball park to work within. Despite leak history since day one, they said it was due to me. Also had fuel injection and throttle cleaning done plus alignment. Seemed to get batter but vibration returned. It has been one of the best vehicles I have ever had to deliver out of. Replaced water pump and auto tensioner while at it.
I would wonder occasionally if I might be in trouble for waiting so long but got lucky I guess. Dealer tested and indicated need to replace rear catalytic converter. I was in the neighbourhood. Most are timid, it's not for everyone. By the way you can't see the timing belt without taking the shields off.
Organic oil actually has better natural detergents that absorb carbon build up better than synthetic. This happened because of my lack of education, not because of the car. So, problem was caused by previous shop repair in May 2015. It may need the dealer to perform a software update. If the valve clearances are excessive, then the efficiency of the engine is reduced because the valves open later and close earlier than they were designed to. Not so with a non- interference engine. It had to be replaced.
Korea, or a startling deal on a Pilot which happens to be my fantasy right now. Valve lash inspection required a special dial indicator setup in which all valves had to be checked and the results written down. Unclear how much dealer at fault. Honda dealers usually have a pretty good deal, better than a lot of independents in some areas of the country. Code reset itself before taken to shop, shop couldn't find a problem, sent home. I just read your article on Valve adjustment a legit service for Hondas.
He was astounded that it was still going. Tech sprayed area around oil pan with leak detecting spray, told us to return in 500-1000 miles. It isn't that hard to figure out, really. Especially coming back from the drag strip with big block Chrysler - ah the days when you had lots of room under the hood. I've got another Ody with 180k, belt changed when it should have been. Repairs not covered by warranty.
Dealer diagnosed the Purge Valve solenoid was failing. I have seen an entire engine carried through a junk yard by a fork lift holding on only by the timing belt. Took all day for repair to be done. Bought it 6 years ago and had over 100k miles and had just gotten everything done. Cleared code and the code has not returned! Idler pulley had significant wear marks.

For those who complain about price - you may not always get what you pay for, but you very rarely get something for nothing.
