Tighten the two or three long bolts in the region of the oil leak. From memory, there are two bolts that join the transfer case to the gearbox up the top, and go through the fifth gear housing. Mine worked lose several times and oil goes everywhere. If you drop the gearbox support beam, and let the ...

Graeme, whats is the cause of the piston problems in 12HTs? Is it because the top ring is to close to the top of the pistion exposing the ring groove to a harsher enviroment? To the OP dont jump to conclusions and start ripping it apart, investigate it properly, could a bore scope be used through ...

You don't adjust the the boost compensator.

'Fuel mixture' is a term used for petrol engines. Have a read, you'll get the drift.

The vehicle that was the test bed for the first of these turbos is my 12H-T. I've now fitted a 600mm intercooler and over the next few weeks, will have another Dyno run. My blog with photos of the intercooler installation on an HJ61 with four headlight is at http://www.peoplehelp.com.au/landcruiser ...

Do you stil get around the average fuel economy mate? Kind of. Fuel consumption has never been terrific with this engine, never got the 10km/l I hear about from others. My average has always been around 7 km/l and it hasn't changed with the turbo, which I assume the question is about. The engine ...

Howdy blokes, Just stumbled across this thread. It's my vehicle used as the test bed if anyone wants to ask anything. What Dieslex claims is spot on - we where there together when the dyno run was done. Doubting South - Yep - fair observation. I think Dieslex had pointed out I'd been a bit over ...

I got a heavy duty exceedy cluych/pressure plate. Gunna get the flywheel machined next week, just wanted a second opinion on the flywheel. Cheers mate. Make sure the flywheel remains thick enough for the clutch bolts to pull the pressure plate in properly. Mine must have been machined before I got ...

12h-t doesn't have a fuel cut off solenoid. Glow screen Heater only switches on below 10°C, so normal starts are possible in most conditions without any heating. and in an emergency situation I fully imagine the engine would start relatively happily and quickly down to 0°C. i.e. it's not something y ...

Hi Perko, It's a bit cold and wet outside for me to go and check my 12HT, but I thought the shut off was on the vacuum line. There is no vacuum in the intercooler/turbo lines - that's all pressure. I may misunderstood what you wrote, but I thought you mean you will weld a barb onto the intercooler ...

Be aware his conversion relies on a tailshaft handbrake.

My clutch replacement including skimmed flywheel and HD clutch was around $1300 installed. Take care the FW has not been skimmed too much before. Mine had been and continued to warp. A new FW fixed the problem, as well as fitting an HD clutch.

I did three turns, but the real test is smoke. Keep turning it until you get smoke under power, then back it off a bit. (provided your injectors are good) Increasing boost will assist EGT's getting too high, but it's all a bit of a balancing act. http://www.perth4x4.net/forum/showthread.php?t=28202 ...

And with all the pumping to prime, it might have tipped it over the edge.

i find it funny how people always relate EGT's with high Boost pressure. EGT's are related to fuel mix You can increase your boost to lower your EGT's people... Of course we relate high EGT and high boost - if you've got your foot on the floor and going up a long hill, both will rise. But yes I ...

I run my 12H-t at 14.5psi boost (which is the trigger point for the factory orange turbo overboost light) and the pyro pick up is pre turbo. I back off at 600°C, normally run to 500°C and have seen 700°C after a 1/4 mile drag <which gave me a bit of a startle> Standard boost 7psi. Also unwound fuel s ...

The pickup is covered in a plastic filter. It's unlikely to block up but I agree with the idea of blowing it back just to make sure. Then you have fun pumping fuel up from the tank again. Have you screwed down your primer pump properly, it might be drawing air if not screwed down. Is there a little ...

Coolant flows out of the top of the engine and into the top tank of the radiator, where it flows down under gravity assisted by the water pump and gets cooler as it goes. Coolest coolant is at the bottom of the radiator where it is sucked into the motor by the water pump. What are you trying to ...

Hi,

I run a CT26 in my 12HT. Not sure why you would want to muck around with adjusting the waste gate springs, when a needle valve boost controller does the trick. A little fiddly to get right, but it's an effective way of adjusting boost. I run mine at 12.5psi.

Try visiting http://www.biofuelsforum.com/svo_users/ for WVO specific advice. WVO does not clean out fuel tanks, not much anyway. Biodiesel does, which although sourced from the same product, they are different fuels. I suggest, no, highly recommend that you do a couple of things. One is to ...

This is a nice HJ61 Safari with very cool timber look interior that I came across in Marble Bar of all places. Looked like a locals car.

I meant to say the vehicle has done 175,000 km.

Hi, As the subject says, I'm slipping out of 4th gear when not under load. Under power or deceleration it stays in fine, but is often slipping out on coast. Over the last few months, 2nd and now 4th are 'feeling' like they don't engage as far, as in the gear lever doesn't move as far down as it used ...

I have some recollection of Fitian converting a 1HD-FTE on the http://www.biofuelsforum.com/svo_users/ forum I run 100% WVO in a 12H-T direct injection. The major issue is to make sure the oil is hot prior to switchover and even more important to purge the oil out of the IP AND injectors prior to ...

I've bought a VDO pyro for my 12H-T Landcruiser hj61. It has a weld on socket in the kit. Can I silver solder/Bronze this onto the manifold, which I assume is cast iron? I want to instal it pre turbo to get more accurate EGT measurements. What tips for drilling the manifold, keeping filings out of ...

The two lines on the removable plate are supply and return on a diesel tank.

All the others are breathers.
