Thread: oil filter....how tight?

Yep, I do it your way - that is by hand and extra 1/4 turn after contact. Even so, I still need to use a filter removal tool (on this and all previous cars LR and non-LR).

Instructions are "to gasket makes contact then 1/4-1/2 turn". The rubber is usually swollen by the oil and the expansion is the issue.

One thing to note, I've had a leak from (and admittedly a V8 D2) under the gasket and found that between a comparison of 4 brands of filter there was a difference in the diameter of the seal. Used some loctite 515 and it's all good. No harder to remove than normal.

I always do up filters as tight as one hand can do, then use a filter removal tool like this one:

It works on all size filters and fits on the end, needs very little extra clearance to operate. Works with an open end spanner if room is tight.

Tightened by hand as stated, still they often require a tool to remove. If the gasket is not smeared with oil on installation they can be very hard indeed to remove even with tools. Last one I had changed by a mechanic had the opposite prob to you; it came loose and spewed oil all over the underside of the vehicle.

Just follow whatever instructions are printed on the side of the filter or box, usually rotate till (oiled) gasket contacts then 1/4 to 1/2 a turn more, always check for leaks after a short run to warm engine oil, Regards Frank.
