Then I spent the whole afternoon behind the bench with various burrs, stones, shop vac, blow gun etc...

The injector protrusions are quite restrictive:

And later, after cleaning those I went to near the line, final port matching will be done after I port the head casting.

This was just a drill to find the tools that works best ands remove that pound of alu away...

Image

And today I laid my hands on the great TJ engine that I got. First piston / rod out was a bit strange. Sort of a new model I guess: :shock:

Image



So, I need a new rod or two... :cheers:

Just keep moovin :D

Thanks for the pics on your porting job. And I did the same thing to me original motor! Hydrolocked the crap out of it. It still drive fine for a long time like that though! I think my con-rod was more bent though lol.

Still doing the disassembly of the donor engine and learning on my way...

Press fit wrist pin - wel that is not usual on this side of the pond. So I had to pull those apart - and I did not want to destroy the pistons. Youtube amde a couple suggestions and the simplest was a puller tool with thread bar:

Image

In the vise:

Image

Basically pressing only around one wall - so no bending or any other stress than just compression around the pin:

Image

Image

Made in my shop, a piece of aluminum, brass, steel bar and thread bar. And must be well lubricated. Also during operation - a couple of times. And with six of those - quite warming up exercise :D

Image

Weight of the rods was within 1 gram, so I guess this is quite nice in the end? Except that I am now missing one.

Hi there,

Bein quet does not mean that nothing is going on...

Meanwhile I was shopping at RA, Summit and Russ.

Russ helped me a lot with final selection of components (Pistons, crank and stuff that goes along). More on those later.

Everything is now being shipped (literally!) overseas inside container with my budd's purchase of some cars... Waiting now...

Meanwhile I was continuing to part out the TJ rengine, that was fighting back to me. I went to gun fight with knive - so I had to correct that.

Perfect excuse to buy the Mig welder that I wanted to have for some time now - and that created additional new project to my pile of projects - folding welding table - trolley:

Image

Image

This was also the opportunity to make some special tools to free the Visco and some other things that were fighting me. Welding gun solved some gun - knife issues :-)

Pulling the harmonic balancer should not be an issue - if my buddy's puller would not be also pretty beaten down:

Image

So I "relocated" the end part to "healthy" thread section:

Image

Then to some strange tools and procedures that I have not seen before...

Sanding jig being made:

Image

Image

Sanding out the line that was created on the valve rocker by oiling channel:

Image

Image

I was balancing between buying new ones or fixing the old ones and opted for fixing old ones as I trust original parts more than knock off aftermarket replacements. They might look OK, but metallurgy and QC ?

Your opinion?

Valve cover question:

I have both versions: stamped sheet metsl and dicasted aluminum version.

What are pluses and minuses of each?

Which one would you recomend to prepare for final fit?

Anybody on valve cover?


The goods have lande in Europe and should be delivered within next days. What I forgot to add to the pack is plastigauge set.

I have seen them in many colors and packaging sets....

What do I need to finish a single stroker build?

A dial bore gauge and micrometer would be much more accurate than plastigauge.

Plastigauge Isn’t really that accurate and should only be used as a last resort.

Good to see the parts are finally getting to you Matjaz. You must be getting excited

Hi Russ,

sure will be fun to have one full day of "unboxing" :-)

Glad to hear about the plasigauge. Micrometers and dial gauges all the way :-)
