Logic's New Engine Build (1 Viewer)

Last one. Everything adds up and bearings are #4 on all.

Dropped off the block at the machine shop today for honing, bath, and light decking. The bath is warm water with soap. No aggressive chemical to destroy the oil pump bushing. Maybe I should replace it while I am here if @landtank or anyone else has any available.
Bearings, rings, and head bolts arrived today. I decided to replace all bearings.
I am hoping to get the head and block back by the end of the week to start assembly.

look at the inside of the oil pump bearing, you will likely see uneven wear on one side. My bearings mimic the factory bearing with a radial groove around the center and a diagonal groove leading to the front to lubricate the contact area between the block and gear. Not sure if others are also machined that way.

Replaced the alternator brushes. They seem pretty worn out.
I also have a couple switches to install. I really like the red hazard switch. Stands out from the rest.

You are right about the wear. There is some visible. Looking forward to replacing it with the one you fabricated. Thank you!

New wiring harness arrived.

Found the clip that is missing on radiator shroud and is responsible for securing the transmission cooler hose.

Chased as many threads as possible including the exhaust manifold. New bolts for the shields.

Replaced rear main seal.

Removed the piston rings to start cleaning the pistons.

Flushed both the front and rear heater cores. I first used warm tap water to push out what ever was left followed by a distilled water flush and finished off with 50/50 red coolant. The final coolant rinse was dazy chained from one to the other to minimize waste. I used a drill powered pump to control flow and pressure. I did not want to over pressurize the system and cause any leaks.

I am going to pickup the block and head from the machine shop tomorrow.
@landtank is shipping me an oil pump bushing. Once I get it, I will start assembly. Thank you, Rick!

This is me inside the engine compartment.

Rinse completed. Ready for a new set of oem heater hoses.

Quality work as always! You have made a lot of progress since last I saw the project.

I sent my injectors out to Mr. Injector for cleaning and flow testing. Just got them back and they look great. Bill was very easy to work with and the turnaround time was about 7 days once he got them.

I cleaned all of the pistons using Chem-Dip for 24hrs followed by two water rinses and finished off with a dip into motor oil. Amazing how clean they came out. No scrubbing at all. All piston ring groves are free of deposits and ready to accept new rings.

Received new battery cables from @Fourrunner. Built very well and extremely heavy duty. Thank you, Mark!
I replaced, what looks to be, the original fusible link.

I replaced the transmission cooler hoses with Gates.

Um, your photography/organization/tidiness/work space/clean work are making me waste way too much time looking at this, kind sir!
Well done!

@landtank oil pump bushing arrived. Thank Rick!

Painted the engine today.
Spent too much time removing silicone in place of the valve cover gasket. Please don’t do that.

The block was degreased and I then removed any missed buildup with a wire brush.

It's prepped with tape and compressed air.

3 coats of high temperature engine paint with ceramic.

Machine shop power honed each cylinder. Well within spec after 300k! Another 300K and then maybe a 0.5 over?

3-angle seats. Full valve job and light decking. Seat guides were perfect.

 

[logicbyondreaso]

Replaced all vacuum hoses and both valves with new.

Made a tool to remove the factory oil pump bushing. Borrowed the idea from @jbpace here

Bushing is out unharmed.

Pressed in the new bushing made by @landtank using his tool.

 

[logicbyondreaso]

Installed all new bearings. Crankshaft and conrod.

Oil squirter.

Lowered the crank slowly and carefully into position.

Did not take any photos during piston assembly. Here is the afterwards photo.

I gotta ask, how do you have so much time to get all this work done? I can hardly make time to wash my rig.

I work an hour or two before work and same after. I have also worked on the 1fz a few times so it's not new to me. Engine is almost fully assembled.

Is there a reason not to paint the head?

 

[logicbyondreaso]

Is there a reason not to paint the head?

The actual head? Or do you mean the valve cover?
The head is aluminum and looks good to me as is. I do have a spare valve cover that I may get powder coated later on. Right now the focus is to get this project completed.
