Are we talking about replacing 5, 6 and 7 in the above diagram? |
Yep 5 & 6 are the returns. 7 is your oil feed, normally it's ok as it's farther away from the exhaust so I would only replace If you just want all new parts as preventative.Don't forget the gaskets for the return lines (number 12) and if you do the oil feed line it uses 3 crush washers, get extra as they are so easy to lose.
Since your in Bahrain, your temps are alot like here in Arizona and probably is a good idea to replace them all (I replaced everything too). Not to many places in the world like where we live subjects these twin turbo engines to 118+ temps. The design was border line before but toss in some extreme ambient temps and stop & go traffic and it's enough to wear everything out that much faster and boil the oil in the return lines. I added some extra heat sheilding to mine you might want to do too.
