Day 21 - Closing in on the internals

A few weeks ago I started started working at a new company. From Sandvik IT Services to IBM. Because of this I got a few extra bucks out of saved up time. I called up a friend whose father owns a complete engine restoration shop since decades and they promised to help me check the condition of the engine and adress any problems. Because of this I decided to speed up the process of downtear.

Also, remember I promised I would pay to increase the space for this blog? Well I did and now I have 5 times as much space and future pictures will continue to be in high definition. Thank you for viewing my site making this effort worthwile!

The work below was actually performed a few days ago but I haven't had the time to update the blog since. I got some great help from my friend HÃ¥kan Hiironen!


Started the day by putting random stuff from the floor into the
new shelves I bought. Looks organized and nice!

Some brackets where still attached to the engine, this
is for the air pump. Fitted with two long bolts.

The alternator bracket was attached with three bolts. One of them
is crazily placed behind the tube connected to the water pump
housing. Needless to say it was stuck and I've tried to remove
it using different tools so I let it be while I thought about it.

On to the oil stick and the tube into which it's fitted. This is just
driven into the engine block and is easily just pulled straight out.

The distributor is attached with the clamp at the base. One bolt
holds it down. If I was to reuse the camshaft and distributor it
would be crucial for me to pay attention to how these go
together as incorrectly reinstalling will result in malfunction
and possible engine damage or at least distributor damage.

This is what the distributor looks like out of the engine.

From within the engine there is a hole to the timing chain. This
is normal but notice how the edge is really rugged. On these
old engines not much time was put into traces of excessive
material. I will have this removed for a nicer look.

The oil pressure sensor. Rotate counter clock wise to remove.

Okay, so I had it with the tube fitted to the water pump housing.
Since I couldn't get it to rotate on its own - I cut it off.
I intend to use a new water pump housing so, no harm.

This is what the housing looks like...

And the engine is getting really clean right now!

Time to go in from the bottom. Turned the engine stand and
emptied the coolant that was still in it...

...and started to remove the 20 bolts that hold the oil pan in place.
It was also stuck to the block so I used a screwdriver to carefully
pry it loose.

This is what the oil pan looks like removed...

...and this is behind it in the engine. I was surprised to see the
thin steel gasket covering the crankshaft, but I understand this
is a windage tray, designed to provide rapid oil return and prevent
oil splash back which, if I understand this correctly, would affect
the rotation of the crankshaft negatively. I am not really convinced
this is a real problem so I need to read into it before deciding wether
to put one on again.

Oil pan and windage tray together.

Removal of oil pump pick up. The pipe was screwed into the
internal end of the oil pump and was easily rotated out of its
fitting just using my hands.

Picture of the internals. I couldn't find any traces of material
in the oil pan or adjacent to the crank so my guess is it's in
decent condition but it is hard to tell at the moment.

Finally, this is how the oil pump is attached to the engine block.
All bolts needs to be removed and these are fitted with a lot of
torque and should require quite some power to remove.

The oil pump internals, more about this in the next post.

At the end of the day, this is the current status of the engine
in this project. I am progressing nicely! :)
Quite a large post today, we're really getting somewhere and my intention is to get the engine block to the machine shop after the christmas vacations. If they can help me with the hard parts and get this block really clean I think it won't take me that long to get the engine back together with new components. The beginning of 2013 will be really interesting for this project!
