It's been quiet for a couple of days, so I thought I'd break the silence with a report of what kind of idiot I can be.
Now that the holidays are over, everyone's back to work and school, and I can get some quiet time to crank up the stereo and get things done, I'm bolting up the heads on this EJ25D rebuild so maybe I can get the mill back in the car during the Chinook this week. Body count on this timing failure was three slightly bent exhaust valves, otherwise things look good.
Having done the left head, I mounted up the right last night just before bed, and first thing this morning torqued it up. For anyone who hasn't done it, it's a procedure, and I still find some Zen focus in it, something I discovered a five or six years ago when I did my first head gasket job on this car, just after I bought it (my first Subaru). I'm normally very task-to-completion driven, but in the middle of torquing one of these heads for the first time, I found I wasn't thinking the way I usually do, rather, I was really enjoying the process. Quite a memorable moment for me.
Anyway, in half an hour or so it was all torqued, so I went to the exhaust cam next, since I'm always nervous about falling lifters. But when I put it in place and reached for the cap... its markings were wrong - they were for the intake. So I looked at the cam - intake too. Confusing... I know where I put them just before bolting up the head... there are the exhaust parts.... oh...
I'd put the head on upside-down.
It's truly amazing, the big things you can miss when you're focusing on little details.
We're all used to trying to be the smartest and most helpful we can, but I doubt I'm the only one who has these moments (and I have a few more, some pretty hilarious). Feel free to share.
