My O2 Zen Life

• May. 4, 2008 - looking for more HP

' the latest projects on Happy Face have been focused on getting more power out of what is an underachieving anemic motor.  With this rebuilt tii engine and its free flow exhaust, 9.5 CR pistons, Weber 32/36 carb, Crane electronic ignition, pushing through a 5-speed tranny followed by a geared up LSD differential, this car goes down the road like a grandma was driving it......its weak so I've focused on a few problems.  One is the severe oil blow by coming into the air cleaner.  Its full of oil and I think the rich exhaust crud is largely due to the excess oil coming out of the valve cover vent.  I addressed the problem by installing a blow by overflow tank..... So this seems to have cleaned up the air intake quite a bit and I immediately noticed much less crud coming out of the exhauast. Then I decided to take a look at the spark plugs, and I found these.... These plugs were gapped at 0.022, which is the 'stock' setting, but not really optimal for a high-compression motor fitted with an electronic ignition and a high-voltage coil.  Not sure why all the oil is there, I hope its not trouble anyway, I replaced these with some new NGK plugs gapped at 0.035, which should provide a stronger spark.  I put some advance in the timing of the dizzy and the motor really runs a lot better.  No question, the dirty rich crud is not coming out of the exhaust anymore and the car idles much nicer. Still, when I take her out on the street, she just doesn't have much grunt.....something's still missing.....
