Outer Limits 4x4 Board

My HJ61 Landcruiser with factory fitted Turbo has done 300,000Kms, we mainly use it to tow our Tandem Van and our half cabin boat. With the uncertainty re fuel supplies, the push towards electric and fuel costs in the medium to long term I wish to keep this vehicle for as long as I can. It has all the options and does whatever is asked of it.

I am seriously thinking of getting the Turbo serviced, what things/items should I look for to ensure that the job has been done correctly as any problems could arise when I am out in the bush 100s of K’s away from the nearest small town. There are no funny noises or whistles from the existing turbo. What would be a reasonable cost for this service/changeover turbo? The vehicle burns about 1/4 lt of oil under heavy load per 1000km.

If the Turbo is serviced/changed over would this put the rest of the engine under a lot more pressure eg Crankshaft which I understand is bigger than the non Turbo engined shaft? In other words should I leave the turbo alone?

I am a firm believer of “Not fixing it until its brokeâ€

Gday pete my old man has an 87 12ht with 274,442 km it is an absolute weapon up the bush but could do with a power up i would pull the turbo apart and replace worn parts or get a new turbo and maybe do the injecters otherwise maybe a slight increase in boost.

mmm maybe your engine could run for 100,000 more km easay .. but if you wanna get it in optimun performance it's good time to make rings ( not necesary overhaul ) , fuel pump and injectors ( Diesel Lab ) with this .. you are ready to fit a oil press, boost and pyro gauge and play with your turbo power ..
