if u go down the road of replacing them, go for the ngk ones, i replaced mine about 3 years ago as part of preventative maintainance(oem ones were good i still have kept them probabaly wasted my money honestly since they were good anway)
you have to separate the engine from the transmission to get the 3 bolts on the back of the sump. so either pull the engine out or pull the gearbox just enough to remove the bolts
what are you talking about friend, the owner who made the thread has a d22 and thats where my repply was aimed at the first place.
but here are the manual pictures as well.
d22 intake engine air comes after the egr valve just past the intercooler and into the engine. no butterflies
d40 intake...
assuming you still have a yd25 you dont have a butterfly to begin with so you can just blank it and be fine.
not all d40's are the same, engines till 2010 accept the blank while newer (euro5 emissions level in europe) dont
earlier ones are fine
i have done up to 1500kg some years back on mine without problems and 1000kg is like a weekly thing for me so no problems there. the right spring is a bit sagged since the wheel arch sits about 1cm lower than left but its a god damn monster.
i was either gonna get the BFGs or Michellin Latitude for about the same price ended up with BFG since they are far superior offroad but would love to give the Michellin ATs a try just for the road comfort. in 4-5 years i hope!
way less aggresive but every d40 i see around runs on these
got some BFG AT's KO2 on my d22 about a month ago, about 600 euro for all 4 (852.379 in australian dollars) pretty pleased and make the truck look and ride nice. only problem is they are stone catchers which they randomly eject inside the wheel arch and make noise when they do like you hit something
d22 and d40 manuals at least in europe say reccomened 5w30 all around but personally i have been running 10w40 for like the past 10 years without issue. tried 5w30 once sounded so bad compared to the sweet sound of the 10w40. at the end of the day its a diesel motor makes a good amoung of torque...
you wont have problem with oil in the maf as long as you follow the instructions and dont overspray it (comes oiled from factory so nothing to worry until its service interval) but do you really want to use an oily filter on a 4x4 vehicle, imagine the mud that it will create when you go offroad...
have you done any work on the timing chain area? if someone removed the timing cover, when you reinstall you have to apply some liquid gasket as well or it will leak a bit of oil like that. nothing to worry about but easy enough to fix
