oil leaking from the front of the engine. harmonic balancer

doesnt have a seal it does however have a rubber bushing in it this

is to take out the virations caused by engine running,hence the

name harmonic balancer . you may however have a bad front

crankshaft seal that is bad this will leak oil at bottom front of

engine so if you are talking bout rubber in harmonic balancer, you

will get ruff vibrations from engine when running, also can throw

the timing out


you will have a MAJOR oil leak.....
