Just changed my oil again and tried to examine it further and the larger "allen stud" is def "out" by 3 or 4 threads and then upon further inspection I find that it also seems to be weeping from the join area where the housing meets the block ....is there also a rubber seal at this point too the same as where the filter screws on or a gasket/sealant ? Also ....is the big bolt (looks like 24 or 25mm) on the housing the bolt that holds it to the block as I notice in the picture above that there are other holes for bolts moulded in the housing ......Should I replace the whole thing ?
Straightsix has one
Thanks again for the info
