Audio is extremely poor, but probably your DMF, however post up decent audio for informed opinions. 6 weeks between oil checks is just simply crazy, you must have money to burn. Alex,
PM received and replied to, and as Ewen has said a cost effective rebuild is the way forward, providing only the faulty parts are replaced. However, if you follow the Nissan workshop manual then you will end up replacing most of the internals.
If you are concerned about the oil quality then I would advise that you swop the oil and filter out for proper stuff now. Best to spend £50.00 now than 3 grand later, on an engine transplant. Alex
Glad to hear that you are sorted.
Best not to let your car tick over from cold as it will petrol wash the bores.
Any warming up should be done when on the move.
Alex.
