Vehicle talk in a car group. Who would have thunk it.
As some of you may be aware, I have a small petrol powered Forklift. A
little Mitsubishi FG15 built in the late 1990's. It's a little 1.5 tonne
It came from a Potato farm in Bendigo a couple of years ago, and as is
typical of a lot of farm equipment, it's had the living shit abused out
of it and is fucked off it's nut :) It's had *lots* of "farmyard mods"
to keep it running. The engine sits under the sit as you would expect,
These little forks run a variant of the venerable Mitsubishi 4G15
engine, which is a little 1.5 litre engine that's been around for
something like 40 years and has been in Mitsubishi cars like Lancers in
boths single and multi valve variants with either carbs or EFI, as well
as some Korean vehicles and Chinese cars under licence. They were also
used in industrial applications like Forklifts.
However, the forklift variant differed from that used in cars. In cars
the engine sat on a 15 degree tilt to allow for a lower bonnet height,
and the carbureted version used a long, angled inlet manifold to suit.
The Forklift application didn't have the same hight clearance issues,
but *did* have a very narrow engine bay so the engine in the Fork sat
straight up and used a different cylinder head and inlet manifold to
make for a narrower package.
At some point in it's life the previous owners of this machine have
replaced the original forklift engine with one from a car, and this is
where all the problems began. Virtually nothing fits well, and to make
it all work, to a degree at least, the previous owners removed one of
the engine mounts and jacked the engine up on one side with a piece of
wood, they moved the air cleaner outside the engine bay for more room,
and had to grind the shit out of the left side of the chassis to the
carburetor would clear and not squash the wiring loom, which it had
already done once and melted half of it, hence the block of wood and
additional relays.
Fucking farmers :)
You can see the differences in the pics of the two engines shown above.
You can also see that the original fork engine had the top water outlet
at the front of the engine near the timing belt, while the car engine
has the water outlet at the rear near the clutch. Hence the messy "over
the top" water plumbing. I've had to modify the inlet manifold, relocate
the air cleaner and redo the water plumbing to make all this work, but
that''s another story.
Onto the purpose of this post. How people fuck shit up :)
When I bought this mess I paid fuck all for it, and despite appearances
it does have some redeeming features although right at the moment I've
forgotten what they are. However one of the things the previous owner
mentioned was that the engine had trouble holding a head gasket. They'd
had it out a couple of times to try to sort it, and even took it to an
"engine specialist" to get it fixed but they never did.
And while I had it apart to do other things I saw why.
When I was fucking around modifying the inlet manifold I had the
cylinder head on and off a few times while I was trial fitting stuff as
I was welding, and I noticed something on the front corner of the engine
block. You can see in this pic here right under the number 1 spark plug
there is a pad there with the engine number stamped into it, and a
gasket face of the block a few times, but to preserve the engine number
they'd set their cutter back from the front and rear pads and left them
top of the block, and I cant imagine anyone doing that in one sitting
unless the block was severely damaged and there was nothing to indicate
the cylinder head back on to double check that I wasn't imagining
things, and I wasn't :)
machined pads and is being held off the gasket at the front and rear of
the block. It was effectively tilting the head over towards the opposite
side, and preventing the gasket from being compressed properly. The more
they cut off the top of the block the worse it got, and the gasket was
never going to seal no matter how hard they turned the bolts.
Fucking idiots :)
I spent this afternoon setting the thing up in my mill and giving it a
has been and just grind some off the bottom of the head for clearance,
but I'm glad I did as the top of the block wasn't exactly flat and it
the back side of the head is shallow. It only needed 5 thousandths and
like this I'm surprised it ran at all.
Oh. Did I mention that Farmers are rough cunts? :)

All neat and tidy like. But they're not all like that. When I got it,https://ibb.co/s5LH2nG
A whole lot less neat and tidy. Typical farmers :)These little forks run a variant of the venerable Mitsubishi 4G15

Turns out that in chasing the head gasket issue someone had machined thegasket face of the block a few times, but to preserve the engine number
they'd set their cutter back from the front and rear pads and left them

They'd clearly had a few goes at it, as they'd cut 20 tousandths off thehttps://ibb.co/HtDXwhF
top of the block, and I cant imagine anyone doing that in one sitting

So, I looked at that for a second and thought "hang on...." and then satthe cylinder head back on to double check that I wasn't imagining
things, and I wasn't :)

Yep. The cylinder head manifold bolt boss is bottoming out on the nonmachined pads and is being held off the gasket at the front and rear of
the block. It was effectively tilting the head over towards the opposite
side, and preventing the gasket from being compressed properly. The more
they cut off the top of the block the worse it got, and the gasket was
never going to seal no matter how hard they turned the bolts.

I nearly wasn't going to cut any more off the block than what alreadyhas been and just grind some off the bottom of the head for clearance,

You can see where all four corners have touched off with the cutter, butthe back side of the head is shallow. It only needed 5 thousandths and

When I first got thing thing it would barely run. After looking at thislike this I'm surprised it ran at all.
