diesel tech

Hi All, I have a 6lpa 315 that I got used coast guard. Had a blown head gasket that we changed. No leaks now, idles and starts fine but will not rev past 1200 unless primer bulb is pumped while running. If bulb is pumped while running it will hit the limiter. Testing on garage...

@DirtSniffer and I have been talking a lot about different options for the OM606 engine. Power goals, transmission options, transmission controllers, etc. After looking how long our conversations have gotten we figured we should start a thread on this motor since I am sure we aren't the only...

Are there any options for the HDJ80 / 1HDT to mount an ARB compressor?

Friends, I have a poverty pack 80-series with the 1HZ engine. 280000 km since 1991. Since it has exactly zero accessories the main thing I miss is A/C in the summers. Otherwise it’s perfect. Does someone know someone that have a thread or have experience in mounting it afterwards? Is...

Hello, Beware I am not an expert on diesel systems or injector pumps and I have no clue what I’m doing half the time, so any advice no matter how simple you think it is could possibly be of help!! Symptoms: running 1HZ under load, losing power, engine stalls, hard to start and sputters when...

81 BJ42 with 3B (24 V) In process of finishing engine install of the original 3b from the 13B that blew a hole through the piston. Had the 3B running and after I pulled the instrument cluster without disconnecting the battery ground, now I have no power when I turn the the key. No power to...

Looking to order a bolt on ready head replacement this week for my 95 series. Seems like a few reliable options out of Australia - the one I have been in communication with is Mr Cylinder Head. Looking for some advice: 1) Mr Cylinder Head in general: anyone had any bad experiences? The kit...

Good morning all, I am hoping to track down someone with a 1HD-FT powered HDJ81 in an emissions compliance area of Colorado (front range). I went for inspection at the emissions technical center in Denver this morning and was told that beginning in 1997, the HDJ81 had catalytic converters...

I recently pulled my 13B (with after market turbo from previous owner) from my 81 BJ42 because I heard a concerning noise. Blew a hole in my piston and there were metal pieces on top of my piston. Had a shop assess the injectors and 1 of 4 were operating normally. I decided to install the...

Just yesterday driving into work.... 700 k km's in 31 years of life since the vehicle was made by Toyota. The t-belt warning light came on as expected to remind me it needs to be done. Is there a contact on the left most number wheel of the odometer that activates the light? I'm aware of the...

I was looking at my 1hdt manifold to plan out my egt gauge install and looked at a ground wire on my valve cover and noticed the ground going to my turbo. I dug around and found this sort or wrapped around the turbo, and it has a male/female plug that goes to a ground. What is it? Tried...

Hey I just bought a 2lt manifold for my early style engine. Obviously I don't need it but I just had a thought. What if I used it as an emergency shutoff in the case of a runaway condition? I could hook it up to a choke style knob in the dash and pull it if I need to use it. Could even use it...

found a very informative video on ve pump tuning by ear and a good explanation on how the boost compensator and fuel pin works

So, I am dreaming of a 1HD-FT swap in my FJ40 (would stretch it 10"). I'd be running an H55F behind the 1HD-FE through for what I am thinking here I might see if there is a way to run an NV4500 or TR4050 instead. Seeing the prices of used 1HD-FT's, it seems that I could get a Cummins 2.8 new in...

So i got my thermostat from Cruiser Outfitters. It’s a crossover 3B, 13BT, 2H, 12HT My memory is a bit foggy, I remember in past the rubber split gasket used to come with the thermostats. Cruiser Outfitters website they are not needed. So the two I received don’t have the rubber gaskets. But...
