all good

hi here are photos one without gasket one with gasket in place also a couple photos of inlet manfold face. After cleaning found these indents obviously from the worn swirl flaps. Fair bit of play in end one qwhich must of been worn for a while to indent the faces. front indent reasonably deep, will check inlet manifold when i pull it apart to see any internal damage, or if i have to raise in dent slightly if required with maybe something like jb weld. Not at mating /sealing surface so should be ok

HI Just wondering if anyone has come across while fixing an oil filter housing /oil cooler leak Have stripped it down ordered new parts The oil filter housing gasket in the one i pulled out has some extra holes cut out, new one has not. Do i need to cut out extra holes in new base gasket. Not sure why these holes were done. watched some you tube and fitted new base gaskets domn have extra 2 holes. Vehicle is audi Q7 quattro 7/08 cas25453 3.o td cheers
