2. If, for example the left, right, or lower
cover of the timing chains has been
removed and resealed, an excessive
application of sealant could block the
oil pump strainers number 1 through 8
of the oil pump (Figure 2). This causes
a leak at the rear crankshaft seal
number 2 (Figure 1), due to an
increased oil level in the lower timing
cover when the engine is switched off.
