M60/B30 (3.0 L DOHC V8 '94-'95 530i)
New issue: Oil pump bolts can become loose, see www.530i.org, maintenance section
Problem Areas (I believe these items are covered by service bulletins)
Leaking cam and timing cover gaskets
Failure of throttle / cruise control cable end fittings
Loose screws on oil pan
'95 models only: Excessive emissions due to long-term deposits on oxygen sensor. DME EPROM replaced.
Other Misc Potential Problems on the 530i
In the event battery is overfilled or boils, vent tube sprays acid on right-side dog bone (trailing arm connecting link) damaging the plastic seals.
Power steering and A/C hoses are poorly shielded from exhaust system radiated heat. Clamps may loosen with age allowing leaks.
