This is only my second post at i-club but I did a search and found there are a few Loyale owners around. I'm not a mechanic but I've had the car for many years and many miles and know it and its problems quite well. So if anyone wants to keep me in mind in case they have questions about it, I may have had the same problem myself and be able to give some advice. At the very least I have a full shop manual.
Mine is a 1991 Loyale Wagon 4WD, normally aspirated, pushing 300,000km.
