just fired the p100 up as its not been run in about 2 weeks and the MOT is tomorrow, anyway the engine is tapping its arse off on the left bank of cylinders.
it wasnt doing this before, and the oil level is fine. i have a few idea's what it could be but was just wondering if anyone else has had this and what the problem was.

 

What engine is it? 24v cossie lump?

 

yeah, it was in my sig, but got wiped as it was to large :/

im wondering if because its been sat and then started its picked some sludge up and blocked/impaired an oil way so is starving the bank. i change the oil all the time so its always golden but i bought the engine second hand so cant say the prev owner always did :/
