- First upload in a new series following my Toyota Hilux Surf / 4Runner rebuild. The block gets stripped down while I wait on delivery of a new AMC Head. Bear in mind this isn't a 'How To' as I'm completely winging it.

The biggest single cause of cracked heads on these motors is the viscous fan unit. Owners see their truck overheating and fit a new rad, 10 blade fans and ATF coolers. If the viscous unit is empty the fan is not engaging at low speed, so if driving in towns, or driving off road, two things happen. The ATF fluid is cooled in the bottom of the rad, the engine coolant in the top. The ATF fluid heats up, and this adds heat to the engine coolant. The fan isn't turning so it all turns into a nice little furnace, and the head cracks. The silicone oil in the viscous unit vanishes after a while, I took mine apart at 220k and it was empty. All it takes is £10 of 7000CST silicone oil, its the same stuff that RC truck owners fill their shocks with, way cheaper than the Toyota stuff. As soon as you start the engine you will feel the difference, there will be a gale force wind blowing under the bonnet. Great way to save £1500 on having a new head fitted.
This is what i've simce learnt. I've some 10000cst on the way!! Will be doing my LC90 also.
Nice good work
Ayyyee! Thanks for the shout out!
Great video, great editing and great B-roll!
Winging it is the best way to go haha.
Would love to know what camera and editing software you use!
Keep up the good work 🙂 the subscribers should come rolling in, in no time.
Hey man! Yeah it's been hit and miss mainly down to parts availability in this part of the world 😫
I use a Canon M50 with Premier Pro. Thanks bro learnt a lot from your channel so far. nice to be able to put it into practice.
@@mikesprojectgarage5123 awesome stuff!
I use the same camera and program lol. Thought your picture quality was good!
@@dingeldiy I also use Cinestyle on the camera for a flat colour profile.
And then in Premier I use a Cinestyle effect on an adjustment layer. you can google "Jarle's Premiere Pro Presets version 4.0" for the free premier presets.
I don't know much about colour grading but this seams to give a nice picture and its a very handy drag and drop solution. How do you find time to get so much online though? Barely making one a month if even
I love hilux surfs myself 👌🤙💯
Aye can't wait to have it back running.
v good vid man, cheers
I am looking at one of these stateside. Ive never messed with a Turbo Diesel. I hope to get one of these in a 5MT and kind of avoid so.e of the othere issues stated above.
How many ks does a motor do the normally pretty strong Motors
Had 270k on this. O think it's more down to how it's used. I neglected to do cooling mods prior to towing which probably shortened the life of the head.
how long did the engine sit with a cranked head? Did the coolant hurt the cylinder wall?
Yes the walls were not in great shape. Didn't need sleeves but was cleaned up in the engine shop.
Well Mike. Have plenty of spares here if you're stuck
Appreciate it. Where are you based?
