Consumer Description

Timing cover leak, all maintenance was completed before the service bulletin. This is a TSB but should be a recall for how common this issue is as they stated it could be caused from the assembly line during a pressurized test. “ This may be caused by oil escaping from a fine clearance created at the sealant applied to joint (A)between the cylinder block (B) and head (C) when the engine was pressurized during leak testing on the engine assembly line.” TSB Bulletin No.: 01-018/18. Timing cover issues are not something that should be happening under 100k miles.
