Piston making for a modeldiesel engine at home (MK-16 rebuild) Part 1
Hello again for a very interesting episode.In this clip I show you,how I
make my pistons self. Its a part of the rebuild of my MK-16, aprox.1956.
I use always old carengine camshafts.With that material( high grade
castiron) I got good expirience in the past. I done a lot pistons so far,
but in the begining,I lost a lot work,because the expirience was
missing.The diesels got moore closer tolerances than a glow engines,because
of the high compression.
The old MK-16 was in very bad shape,impossibel ,to be a runner.The rear
disc was worn out,the 2 bearings, very bad,even one broken....the prop
collector was not from this engine (and broken also) and the most important
thing,no compression at al.
I buy a lot special tools,what makes it possibel,to do this work.But its
stil a kind "on the edge" job. Its not easy to do it with this hobby
In 2 evenings with each moore then 2,5 houers,It was finally done.
...But I make a mistake( also a lot in the text,ha,ha...sorry)
...I shoud first make the final size with the grinding as first
step...and after that,drill the wrist pin hole. .Because the holes have a
influence on the grinding pattern,its moore accurate to grind a closed
Because of that mistake,I got extra work,to get the piston lapped wel and
sealing wel.Its now oke,but next time I must not forget it...save much
time,and fare better result! I l also dont make the rings on the outer
piston. The wal thicknes is less like the orginal piston.I wil risk a crack
forming or even a broken part...so I deside not to take the risk.It run
fine anyway without it.
The MK-17 also dont have it anymoore...But I see this strange aplication
also on my Russian K-16 engine from 1950 !..same factory I asume. )
I hope you like the visit in my smal workshop...enjoy part 2!

THIS WAS DONE ON A SHIT BACKROAD THAT LEADS TO A FARM NO MOTORBIKES COME
DOWN THIS ROAD UNLESS THEY WANT A SACK OF POTATOES BUT TRY PUTTING THEM ON
.The second part was filmed on a more used road but oil had all gone by
then so stop worrying i ride a bike to you no.
Amazing footage of a set of normal 4 cylinder car pistons moving at normal
speed and more. As a petrol head i no this happens but to actually see the
speed for real is just wicked. My favirite bit is when they look like there

How to lap valves on a 1995 Eclipse Talon 420a head (non-turbo)
When my 1995 eclipse timing belt broke I knew that there was a 99% chance
that the valves were bent in the process. I searched the internet for a
good way to replace them, without having much luck. I figured I would try
and come up with something myself, I figured I would document the whole
process of valve lapping by video...hope this helps you if you are in the
same bind as I was!!!
1994 Honda Accord w/ Bent Valve
A video illustrating how your 94 Accord's engine will probably sound if it
has a bent valve. Bent valves often happen in cars containing intereference
engines, such as this particular model of Honda. They occur most often when
the timing belt breaks during operation of the engine. This is an expensive
repair, requiring the engine head to be dismanted. To avert this disaster,
change your timing belt every 90k miles or sooner. This particular car had
about 178k miles on it at the time of the video. There was a bent valve in
cylinder 2, and the cylinder lost all compression.
