I'll be having 3 weeks holiday soon, hopefully I can machine some Datsun parts and drop the engine in the engine bay again!

 

Painted some more parts during the weekend:

Finally on holiday, feels good!

 

Bought some cork gasket and made new oil pan seals:

Also wondered if the oil thrower disc is necessary? I hear that oil might leak from the front seal if the seal is worn or something. The problem was that I couldn't find the thrower disc anywhere, even the other donor motor didn't have one?

Anyways assembled some screws on:

The other question that bothered me is that what sealant should be used with paper gaskets? I have heard that some use grease to make them easy to peel off later on and the gasket material itself seals, no need for silicone sealant? 

 

Painted the water inlet and also the crank case breather line:

Which now has AN fitting:

And had some time between paint layers so I decided to paint the engine numbers:

Got the holders finally in right size:

Made the oil pump spacer, will do a 3D SLA print to try out how it fits before machining one out of aluminum:

Also planning to do multiple intake flanges (also for sale):

Machining time!

I ran to an error first because the block size in the CNC control was limited to 9999 blocks, and I had to go through 99999 blocks. So:

img_20201016_114330_by_atomicsickness_de

I fixed that with some piece of code that resets the counter everytime it reatches 9999 blocks, it starts again from 0...1...2...3.. etc. After that was fixed, everything went smoothly:

img_20201016_161652_by_atomicsickness_de

img_20201016_164338_by_atomicsickness_de

 

Except when I had some errands to run... So I stopped the machine and calculated that I was somewhere around 58k blocks down the line... But of course that block would be 8k something as the resetting counter... So I tried to delete the all other 8k blocks and start the program then from the ''58k'' block, but it didn't work... So I had to delete all the code until 58k block and modify the starting counter and then it was easy to continue:

So first batch is ready, 2 pairs are already reserved. One pair from this batch is for sale. Send me a DM and I can customize the oval hole size suited for your application.

 

I'm also making oval to round port adapters in next batch:

de718w6-6cd9ed48-8cd6-4adb-a331-1f6c1dd8

 

So they are easier to weld on.

 

Pricing:

80 euros per pair w/o adapters

125 euros per pair with adapters

 

I will also machine the oil pump flanges, so hmu in DMs if you're interested in any.

Milled more, got the first pair ready, I'm going to use the first pair to myself with weld on adapters, so the oval holes are bit bigger:

img_20201017_152610_by_atomicsickness_de

 

Then I'm going to make a Jig from leftovers to house in the intake funnels that transition from oval to round, the jig will be used to machine the transition (see radiuses):

And started to make the jig where I can do the finishing transitions between oval and round:
