    Sticky 12HT injector question

    I Recently stripped the head to be shaved after blowing a head gasket and noticed carbon deposits on the injection nozzles. I soaked the injectors in brake cleaner and wiped them over with a soft cloth to clean them up a bit. After re-assembly and start up there is a noticeable miss and...

    12ht injector costs

    The 12HT is direct injected versus the 2H which is indirect. The 12HT injectors are a totally different design and much stronger meaning they cost sh!t loads more. I think the last time I checked it would have cost me $1000 just for the injectors. That was a few years ago too.

    3B head crack repair: generally worth it, or just find a new head?

    Haha. I remember my old man shoving an old fertiliser bag over half the radiator in winter when he had his old 45 with the H motor.

    2H Turbo oil leak

    I know it dosnt look like much bit that pressure sender hanging off the side of the oil cooler may be a bit heavy for a brass fitting to hold with the amount of vibration a 2H produces. It just looks to me the extra fittings are amplifying those vibrations and causing a fatigue point at the...

    CB Mounting ideas

    Over head console is the best. Got one in my 75 that has a heap of shelf room up there as well.

    New cylinder head retorque method

    I always re torque anything that is exposed to a high temperature differential. It may be over kill to some but it's cheap insurance for me.

    New cylinder head retorque method

    Loosen head bolts 1/4 turn in reverse order of tightening sequence. Then re tention bolts in three stages till recommend torque is reached. This should be done when engine is cold. See attached pic for 2H/ 12HT sequence.

    Hj61 axle stud help

    Are you running a locker? I had the same trouble running a Detroit locker in the rear, when the torque release mechanism clicked over on a paved surface it would send a shock down the axle and pop the studs.

    1987 hj75 ute with 12ht

    The throttle is a bit twitchy with a 12HT but you do get used to it. There are times I still need to steady my foot by holding against the kick panel but it's pretty much automatic now.

    Keep or replace Release Bearing?

    Replace it now. Much easier than having to do it 12 months down the track if it dose fail.

    Clutch/brake problem related?

    Better option than my effort... I lost all drive power during a gear change so I pulled the transmission expecting to find a worn clutch. Should have known I couldn't be that lucky, clutch was fine but the rear main shaft bearing cover had an odd looking bulge in it. I stripped the box and...

    ever hear of a oil filter blowing out on a bj or hj diesel?

    Yep, had that happen to me once. The pressure relief valve can work a grove in its bore and get stuck blowing the oil filter and contents of the sump onto the ground. Good thing the 2h motor has a auto shutdown when oil pressure is lost.

    2h oil cooler question

    Just bought a 86 troopy for my better half and after taking it for a short run (about 50 kms) it blew a heater hose and after letting it cool found oil in the radiator. After assuming it was the head gasket I stripped the top half of the motor but the head gasket was still intact only some...

    12HT cooling problems.

    It was the head gasket. Had a hole burnt from the No 5 cylinder to the water jacket. Driving to work and it blew the top radiator hose off the thermostat housing, let it cool then refilled to try to get it home but water got into the cylinder and hydraulic locked the engine, luckily it wouldn't...

    2H rocker assy

    Just wondering if anyone can tell me if the rocker assy from a 2H is the same as 12HT.

    12HT cooling problems.

    Refilled the fan clutch, flushed the system and everything seems to be working fine. Thanks for all the advice.

    12HT cooling problems.

    Thanks, I do need to refill the viscous coupling on fan clutch and will check water pump and flush radiator & cooling system and see if that helps before I start striping head.

    12HT cooling problems.

    I own a HJ75 Series landcruiser. I have replaced the original 2H engine with a 12HT which has given me no trouble for 3 years until recently. During normal hwy driving the radiator spat 1/2 of its coolant out the overflow. After refilling bubbles can be seen in radiator at idle and frothy...
