But an older engine with the VDO (metal can) type sensors. Correct?

All of the engines shipped to RV-12 builders have a newer (and now there is a newer than that) sensor.

Yes you are correct, an older engine with the VDO style type sensor (both with the ring and without). My new engine for the Highlander came with a Honeywell sensor. From what I have read on numerous websites and blogs the Honeywell doesn't fare much better. Based on my previous experience I plan on remote mounting a VDO senor.

I am one of those builders that follow the plans and makes very few if any modifications. This is one that was made because the failure mode was unacceptable. I have heard others have never had a problem with the way it comes from Rotax.

Thanks for the replies. My original Honeywell has 80 hours with no problems yet. Now at least I know the common symptoms.
