ZZ4 Harmonic balencer info & part number
Hi , my friend has a ZZ4 in his C2, installed in his Corvette maybe back in 2007.
Wont idle goes between 600 / 800 very rough...when ignition turned off engine runs on ...the harmonic balencer appears to be loose
Can the balencer be tightemed & engine retimed ..or could the fact that
balencer was run loose , caused damage to rubber bushing ?
What is GM part number for balencer ?
Thank you,
The Dog

if the bolts are loose, tighten them, if the rubber is shot replace it. The part number is 19260269
