The Steele item does not have the correct inside profile for re-installation of the interior garnish molding leaving huge gaps at the upper corners. Had the same problem with the rear window but worked around it but it still doesn't look quite right. The interior guy even asked if the garnish molding came off the car. It did.

Are there left and right sun visor brackets? If so I need a right for the above Olds although I expect Chevy and Pontiac would be the same. ]]> Oldsmobile - Technical BobOlds http://forums.aaca.org/f138/olds-windshield-gasket-353073.html 1937 F37 Oldsmobile Piston Question http://forums.aaca.org/f138/1937-f37-oldsmobile-piston-question-352539.html Sun, 02 Jun 2013 20:47:03 GMT I just changed my oil after first 500 miles on newly rebuilt engine.

When draining the oil a bolt and some pieces of thread shoulder came out. Not wanting to damage anything, I removed the oil pan and discovered where the bolt and pieces came from. The bolt is the locking screw on the piston boss from the rear piston pin and the pieces are part of the bolt thread shoulder housing. To properly repair, I would have to replace the piston.

My question, if anyone knows, will it cause permanent damage if I don't replace this piston? What exactly does this locking screw to the piston pin do? Will it cause excessive wear to piston or cylinder or rod, and over what period of time? Engine was running perfectly at the time and I will only be putting, say, 500 miles per year on it.

Thanks very much.

Is there a rebuilding service for these?

The issue is that recently it barely passed a CA smog check on the HC emissions. Since I'm going to replace the valve covers gaskets (leaking) and will have to remove most of the AIR system for access, I figure that it's a good time to fix the HC problem. The car has 33k miles on it, does not use any oil between changes, no trouble codes set, Check Engine light functions as it should with no problems, engine runs normally and fine. Timing is within allowable specs. AIR system checks out fine per the fault tree in the Olds factory shop manual.

Here are the emission test numbers:

Feb 2013:

Test Spd/RPM /%CO2 /%O2/HC(ppm) /CO(%) /NO(ppm)
15 mph /1636 /13.6 /2.1 /102 (fail limit is 103) /0.07 (limit is 0.54) /335 (limit is 762)
25 mph /1638 /13.3 /2.5 /65 (fail limit is 69) /0.02 (limit is 0.40) /451 (limit is 643)

Aug 2011:

Test Spd/RPM /%CO2 /%O2/HC(ppm) /CO(%) /NO(ppm)
15 mph /1635 /13.2 /2.3 /20 (fail limit is 103) /0.01 (limit is 0.54) /421 (limit is 762)
25 mph /1490 /11.4 /4.2 /21 (fail limit is 69) /0.00 (limit is 0.40) /476 (limit is 643)

I also have a '73 Impala with a 350 and AIR system, when it was under smog testing, it would have HC/CO results like the Aug. 2011 results above, without a catalytic converter. So, I am thinking that even with a weak or defective catalytic converter, I should not have the high HC numbers as shown in the Feb. 2013 results.

Any suggestions on where to look are appreciated! ]]> Oldsmobile - Technical Writer Jon http://forums.aaca.org/f138/high-hc-readings-1986-442-a-351703.html
