So non reatta related car story to share here. My brother in law owns a 2001 Honda accord and for some reason it blew out a spark plug a couple weeks back. He took it to a shop and they did a thread insert and sent him on his way about 10 days later he started getting engine codes for misfires. So he brought it for me to look at.
At first glance I noticed the ignition coild for the plug that the shop had repaired was not sitting all the way in the tube and was a quater of an inch off the mating surface of the valve cover. The coil mounting screw was screwed in just like that (meaning the shop left it that way). I tried to figure out why it would not go in all the way. Decided to pull that plug out and inspect and it came out mangled thread insert and all (picture).
Even left one of the leading threads in the cylinder head. Needless to say I was like ****! We are up a creek now.
Bit the bullet and decided there was nothing for it but to replace the head. Pulled a junkyard head that seemed in decent shape other than some oil sludging in spots. It was real unfortunate because the original head that got messed up was as clean as could be. Whoever owned the car before him took really good care of it. See the pictures for comparison.
Original Head with 150k miles:
Junkyard head (mileage unknown):
But honestly other than it seemed that this new head probably saw cheap and less frequent oil changes, everything seemed ok with it. Cam surfaces were clean with no real signs of wear. Rocker arm to valve clearance only needed very slight adjustment.
Got it back together this past weekend. Took me 22 hours but I move slow when working on something new. That and in my haste to remove the junkyard head, i destroyed the wire for the coolant temp sensor, which is tucked behind the timing sprocket, and did not realize until after I got the timing belt and timing cover all back on.
But it's running good now. Had a high idle problem that boiled down to the cruise control cable getting out of adjustment during removal and reinstallation to the throttle body.
Anyway that is my weekend car story
