More progress: bellypan build & engine repairs

Several projects are in motion at once now: diffuser and bellypan, valve adjustment, timing belt replacement, oil pan gasket replacement. I took the car off the road, which is making the daily schedule a PITA, so I need the car back ASAP. Here are some pics.

The rails for the middle part of the belly pan, drilled and ready. Tonight I installed three. Need more hardware for the fourth:


The current state of the diffuser. Yes that's wood in the section that will be under the axle. I was trying to save plastic sheeting, but I might change the plan. The curvature is being reduced overnight under some old tires:


A couple of the exhaust valve arms. Grimmy and crispy, with a burnt black carbon on em:


Underside of valve cover... more crispy gooey grime:


Closeup of crispy goo-grime carbon build-up:


Adjusting the valve clearances tomorrow. Building a frame for the diffuser.

All valve lash settings adjusted today to maximum specs. First time in 100,000 miles. Needed doing for August emissions test. No work on mods.

Next is the timing belt and more work on the bellypan and diffuser.

"Maintain before mod."

I wonder if I should do this to my HX, I'm fairly sure that it hasn't been done in the 199k miles this car has been driven.

It should help emissions, which can be a cha)enge with these older cars. I was close to the max limit in one category two years ago. So I'm going for overkill: since then an O2 failed and I replaced both, but now I plan to change the oil and its filter, the spark plugs, and the air filter in the day or two before the test too. I'm debating whether to clean the CAT with citric acid before the test, or wait and see if I fail, then clean, then try again, then buy a new CAT if I fail twice. The car never has failed, but for some reason the test makes me nervous, lol.

When I did my smog not even a month ago, I wasn't even close to failing in any category so I think I'll hold off on doing it. However I am getting really weird power losses still at takeoff, I think I'm gonna change my fuel filter and see if it helps. Meh.

At the time I did my last smog, I had recently solved a misfire problem, and ignition coil fail. And the upstream O2 was apparently approaching fail. Maybe it won't be such a biggie this time.

Now I have a stuck crank pulley bolt. I have the special tool for it. I bent an extender on my breaker bar, trying to torque the thing loose. Just thought of P-blaster. Now I wait (and get another extender).

Doh! I hope it does not come to that. Went out with wife and friends tonight. No wrestling with the p-blasted crank before dark. Hope to finish tomorrow! Hope!!

The crankshaft bolt gave me a lot of grief on my LX. I had to borrow a buddies dewalt electric impact to get it off. I have a cheapo harbor freight electric impact that almost always takes anything off, but it wouldn't take that bolt off. But, it wasn't a problem on my cousin's EX when we changed the timing belt on it.

I remember your struggle. I am hoping I can avoid a tool purchase, because I don't have a friend with that stuff in this county.
