PROBLEM:

OIL LEAKAGE FROM SUMP BOLTS

CAUSE:

On all V8 engines with cross bolted main bearing caps, the drillings for the four sump bolts indicated by the arrows in the illustration, pass through to the adjacent cross bolt holes.

It has been established that an oil leak path can develop down the thread of these sump bolts.

ACTION:

In the event of sump removal or oil leakage around the heads of the sump bolts, remove all traces of oil loss and replace the bolts indicated in the illustration of the sump underside, with the bolts detailed in PARTS INFORMATION .

The new bolts incorporate a sealant patch and are fitted to V8 engines from the above VINs.

Ensure that the longer bolt LSZ100000 is used ONLY at the Discovery oil • cooler pipe bracket location, see ‘A’ in illustration.

If only changing the four bolts, hand tighten the new bolts first, then torque all • bolts to 23 Nm using the Engine Overhaul Manual sequence reproduced above.
