Beware charcoal canister breakdown! - ZR-1 Net Registry Forums

VetteMed · 05-18-2011

As mentioned in my hi-miler thread, it would be a smart idea to check your charcoal canisters periodically. Mine started to deteriorate, and sent charcoal pellets all through the vacuum lines, solenoid, and presumably into the intake and cylinders as well.

I recently noticed that the engine would fire at the first crank, very unlike what an LT5 should be doing. I now figure this was due to constant fuel vapor venting from the tank into the intake, since the purge solenoid was lodged open due to charcoal pellets present.

New canister is around $60, new purge solenoid around $30. Guess it's still cheaper than owning a boat.
