If you have never used a ring compressor like the one in the picture, you will never go back to the old way. Worth it's weight in gold. These rings are so small, they will break looking at them wrong. Lol

One thing I really like is that Weisco makes their rings a file to fit. Oil scraper rings were fine at where they are, but for those that have never done this before, buy a ring file. I wish I had taken some pictures of that. I get going and I don't want to stop.

I use the piston top to push rings down the bores, so the rings are square in the bore.

Each ring set needs to be done for each separate bore, so number your pistons and rings so you keep them in the proper cylinder.

This is what can happen if you have you're ring ends butt up to each other. Always check ring end gaps. Even if the manufacture says they will work.

Sadly this engine only had about 30 hours on it. It's a 8.1 boat engine. Every cylinder but two looked like this. On some you can see the top ring parting lines right where piston break is. This is what we call ring land lifting for those that don't know.

And no I did not build this one, happy to say.

Nice work and pictures, thank you for sharing.

FWIW I had to cut down some of the main studs to get the oil pan to fit. You may not since it's a different platform... different oil pan??

Just a heads up


Also yes I write stuff all over the place during a build so I don't have to keep looking at pictures. My build is exactly like yours so far, just coated some more things. I don't want to hijack your beautiful build and will start my own when I get the chance.

My studs look the same as yours. I just didn't show the picture. The LSJ wouldn't need the studs cut. Deep pan on those. Thanks for the kind words Dr Loch

Like you state in post#39, I ordered one here on eBay

They are identical to these, I believe the same guy

Oldblue, you are right that is Jeff. Funny I asked him a couple of months ago about the arp bolts and he said he didn't have them. Nice package. Good find.

Oldblue

I'm satisfied with the purchase! I'm always concerned with that top bolt snapping, many others have had that problem or the guide breaks!

This is the beginning of the manifold build. For the ones who don't know, with a twin scroll manifold on a 4 cylinder engine, to make the turbo work the way it is supposed to 1 and 4 pipes have to go into one side of the turbo and 3 and 4 into the other. It's a pain to make everything fit, but the turbo spools up 200 to 300 rpm faster and just the over all drivability is better.

Turbo on just to give an idea of how it will look.

There's room for that between the head and the firewall?? It's to cool to hide back there!
Any thoughts on header insulation tape to keep the heat down?? Or a blanket in the turbo?
