•Cold-start the engine and listen carefully for timing chain rattle or ticking from the front of the engine, walk away if present
•Check supercharger belt and idler pulley condition; look for belt glazing, cracking, or fraying and feel idler for bearing roughness
•Inspect both valve covers and spark plug wells for oil seepage or residue indicating gasket failure
•Review full service history for oil change frequency, cars serviced only at manufacturer intervals and driven hard are higher risk
•Request or check for evidence of timing chain tensioner upgrade to an aftermarket or LS2-style dampener
•Perform a wide open throttle boost check (or review a datalog) to confirm the supercharger is building full expected boost without slip
•Check VIN against GM recall records for the oil cooler line campaign and confirm any required work was completed

Supercharger Engine Oil Cooler Line
On some 2009-2013 model year cars with the supercharged 6.2L LSA engine, the oil cooler line fitting can crack or leak, allowing oil to contact hot exhaust components and creating a potential engine bay fire risk.

Mk2 · Mk2 Supercharged
✓Extremely strong and proven LS-family short block capable of handling very high power levels on stock internals
✓Large and active enthusiast community with well documented fixes and upgrade paths
✓Supercharger design (roots type) provides immediate low RPM torque and is considered more streetable than turbo setups
✓Aftermarket support is exceptional: parts, tuning, and crate engine options are widely available
✓Stock timing chains have demonstrated capability well beyond 1000whp in documented community builds once the tensioner is addressed
