Over time, the engine can leak oil at various locations. Early-production vehicles require engine disassembly and modification to resolve leaks at the cylinder heads, oil return tubes, valve covers, timing cover, chain housings, case through bolts, and lines to/from the oil cooler.

    Engine smoking at idle from driver side. Then, oil puddle found under car after winter storage. Upper valve seals need replacing. Done at dealer. Mid- price fix. Around $1000.
