I have a 2008 kubota rtv1100. i just replaced the second mechanical pick-up fuel pump on it,and the brand new units leak crankcase oil from where the mechanical "tickler" pump runs through the housing,,,,,,,i can understand a faulty 1st one,but,now the 2nd? same issue? im now wondering if possibly the engines PCV system is not functioning properly,allowing too much crankcase pressure and forcing oil out of the pump? can anybody help me as to where to look for this pcv system,to test it,thanks so much in advance

Is a possibility. When I bought the 82 GMC with 6.2 diesel it's oil fill cap (doubles as the breather) had been replaced with a newer cap from a 6.5 (non vented). Engine originally leaked out of everything but the rear main seal. Swapped it to the correct cap and all the leaks stopped.

The air will make a way out if the breather is plugged up.
