Evening all, can anyone help with the following, PD150 (ARL) having issue with oil leak from dipstick where the orange part joins the metal part that comes out of the block (hasn't snapped or visably broken) I'm thinking the o-ring in there needs replacing for starters but considering its a few inches higher than sump why is it leaking from there?
I've had the breather pipe off on the TIP end (couldn't remove it from rocker cover end) but all seemed clear only very light oily coating as to be expected so if breather is clear any ideas on what could push oil up dipstick? which is my guess as to whats happening to cause oil to leak from where it is.
One question though is that all the breather is is one pipe from rocker cover to TIP? no gauze filter or is that integrated into the rocker cover? seemed clear anyway. What else could pressurise crankcase? boost leak?
Any suggestions appreciated, cheers
