Hi all. I've recently installed an oil filter sandwich adapter on my 2000 Saab 9-5 2.3t to allow me to easily install an oil pressure gauge. Installation when well. No leaks were apparent. When I changed my oil the other day, I almost unscrewed the adapter along with the oil filter and had to re-tighten it. Does anyone know if there is any problem with using Loctite blue or purple (NOT red) to make sure that the adapter plate doesn't unscrew with the oil filter at each oil change? Thanks.
