cheers for that, Mine is the 5 cylinder non turbo model and has no tappings in the side for the oil cooler and i have seen several filter housings that look as though they will fit with the oil cooler tappings but no one will say they will or will not work. I have been told that merc just added cylinders so most parts fit the 4/5/and 6 cylinder engines but i am a bit concerned about damaging my otherwise excellent engine. thank you for making it a bit more clear. but the oil housing are hard to find now. best regards andy
