My engine is 21214. How can there be 2?That table is a great visual aid...but the more hard info I see, the more questions come to mind.
If the root cause is the rumored bad valve batch, I would expect failures in a tighter cluster of engine build dates -OR- a much larger number of reported failures within that ~2 month window.
No??? This info makes me think there was intermittent valve defect across a production run much larger than a 'batch'.
Engine Build-Date 21160 (09 June) 21161 (10 June) 21166 (15 June) 21209 (28 July) 21209 (28 July) 21214 (02 Aug) 21216 (04 Aug)
