Working on PCV again, I am going to try for the exhaust. My basic plan is, valve cover to stock pcv valve, to a catch can, then block to the catch can, catch can to the exhaust.

My 3.12L is finally going in!

Nice, correct engine block color.

I had a great black wrinkle color paint when I first did my turbo swap but they apparently quit and I have yet to find a decent substitute. Yours looks pretty good. Mine could use another refresh...

Where is 7B? I was raised in 8B...

Oh... Canada - way the hell and gone from SE Idaho...

I am near Canada:)

A fun z video I just was sent. It has my R35 coil bracket on it and has over a 1/4 million views! How cool is that.

Hilarious, experienced all the same issues minus DBW.

Really cool he documented the process, it's a journey.

Congrats on the coil bracket.

Finally got my exhaust finished. With the kenmeri header mated to my Fujitsubo exhaust. There was a small gap between the flanges. Designed up a small spacer.

This is 316 stainless.

I ended up taking it to a guy that did the vapor blasting on my valve cover $75 Seemed like a nice guy but the product didn't turn out that amazing. So it's been glued and screwed to the cylinder head now and I'm wondering if anybody knows a compound that I can rub on the aluminum to spruce it up a bit thanks in advance for any tips

For you that have been following along. My 3.12L is finally in my car and home. Gosh it looks so good I’m just going to stare at it! Amazing work by Andrew Kazanis!

This engine was built and done prior to a shop fire. So it’s been through a lot!

I love the contrast of the stock blue block and gold zinc and black.

Congrats,

Thank you for detailing your journey, your details have helped many along the way. Good luck with the parts developed through the process, all great solutions.

Now get out and drive her.

Cheers!

Looks like you might have some weather to contend with over the next few days for driving. It would be fun to hear the exhaust note and the sound of those horns breathing. It has been fun watching the build! We played Bonner Ferry and also the course up in Creston when we had a condo in Sandpoint. There's another course we played that's on the road heading east from Sandpoint that was called Hidden Lakes but I think the name has been changed. Oh and there was the afternoon sitting in the "husband" area of the Coldwater Creek store, I was almost thinking my wife got lost in the store.
