Folks...I have a 92 LT-1, 129K miles, runs great, passes smog test with
flying colors, etc. Did an optispark, water pump, and radiator fan two years
I look at other same vintage cars and their engines are sparking clean. And
while I'd like the same, the Optispark issue has always kept me from
cleaning it off...
Am I missing something? Can it be safely cleaned? My Opti went out when I
bled air from the cooling line at the front of the throttle body, and wasn't
paying attention, and got some cooland drain down to the well-placed
So anyone have any ideas for cleaning an LT-1, with the original Optispark.
Didn't feel like the amount of disassembly needed to upgrade the Optispark,
I was told it required pulling the camshaft.
Let me know, please.
