yeah,looks like 4d56 dohc engine piston. but replace ALL 4 PISTONS! http://www.ebay.com/itm/MITSUBISHI-L200-2-5-DI-D-16V-4X-PISTONS-SET-STD-PISTON-RINGS-4D56U-2006ON-PAJERO-/181595042877?hash=item2a47e8743d:g:uQ0AAOSwAL9UdIgr&vxp=mtr '' in most cases, if one piston is bad, the others are too so all would be replaced as a complete set. Many pistons that appear to be in good condition and show no signs of scuffing may still have to be replaced because the upper ring lands are worn.'' http://www.enginebuildermag.com/2007/02/pistons-rings-details-every-engine-builder-should-know/

bov's can only be fitted in turbocharged engines Turbochargers introduce large amounts of pressurized air into your engine. When your throttle plate closes however, this airflow has nowhere else to go but backwards, which sends it back towards the compressor. This pressure wave tries to reverse the rotation of the compressor which at times can be spinning at many tens of thousands of rpms, and the resulting stress can cause failure of the bearings or the turbo itself. What a blow-off valve or recirculation valve does then, is give this pressure wave a place to go, reducing stress on the turbo and improving response. copyright http://www.autos.com/aftermarket-parts/do-you-need-a-blow-off-valve-for-a-supercharger
