On rear wheel drive engines, the oil pan at the bottom of the engine does not completely connect to the block. It has to make room for the crankshaft at the front and the drive shaft/crankshaft at the rear. this is a half circle design in the oil pan to match the same design at the bottom of the block. In order to keep your oil in the system, there is a gasket that is either heavy cork or rubber that conforms to the shapes of the pan and block while at the same time it is wrapped around the crankshaft. When either the front or rear "main seal" "blows", it is simply worn too thin to prevent the oil from leaking out. The same theory applie to front wheel drive engines.

It doesn't necessarily mean a bad engine but with this mileage, you might as well go for a rebuild since if you just do the head it porbably will start using oil.
The engine is burning coolant caused from a blown head gasket or cracked head if you are loosing coolant. If you have a turbo charger the seal can go out and cause a Lot of smoke from burning oil..
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 ANSWER you will have a MAJOR oil leak.....
It would be more cost effective to replace the blown engine with a re-manufactured one.
No, Seal-Krete Epoxy-Seal is an acrylic-epoxy blend. By mixing 2 unlike resins (patio paint and Epoxy-Seal) the hard Epoxy-Seal acrylic-epoxy resins would become weak resulting in a coating failure.
