Vernatherm

[Tmarsha]

Hello, in the process of installing an Airwolf remote oil filter kit, I was taking loose the Vernatherm housing and the valve dropped out of the housing along with 6 washers. Not sure why it dropped out and why the washers? My mechanic had another one that we put in however the seat looked like it had some wear. I have the 2nd oil cooler STC not sure if that has any relation to this. I couldn't tell what holds the valve in the housing. I was looking at new ones and they want $200-$300 ouch. Getting ready to go fire it up to check for leaks. Any feedback is appreciated. Tom

There is a lycoming service bulletin that deals with the nut working loose and falling apart.  I purchased a new one when I overhauled the engine 3 years ago.  I remember it being around $150 for the pma equivalent. I either purchased it from aircraft specialties or aero-in-stock.  My old one was working when I overhauled the engine if your interested in it I can see if I still have it.
