How to final wash an Engine Block

You just picked up your block from the machine shop, and your ready to build your engine.
The block may look clean, but it is not.
It still has grim and grit from machining in it.

It is up to you as the builder to final wash the block.

First gather together what you will need to clean the block.
Lint free paper towels, WD-40 , a good degreaser and a can of brake cleaner.

Now find a place to wash the block, a table or engine stand will be fine to use.

Now spray the degreaser all over the block, take good care to get the inside of the block and cylinder walls.
Let the degreaser work for 15 to 30 minutes, Do NOT let the block dry, reapply as needed.
Now spay the block down with clean water till the water runs clear.


Now quickly blow the cylinders and main bearing saddle surfaces dry with compressed air.


Now spray WD-40 in the cylinders and main bearing saddle surfaces to prevent rust.

Now spin the block around and spray brake cleaner into the oil galleys, I would recommend that any oil galley plugs be removed for this step if they were not at the machine shop. Just make sure to install them back.


At this point, take compressed air and blow through all the oil galleys,


main and head bolt holes.

Repeat till all signs of grit and old oil is removed.
Now take a couple paper towels and fold into ¼ and spray WD-40 on them, soaking them well.

Now wipe the cylinders down

Look at the paper towel now. This is hone stone grit and rust. Leaving this in the cylinders can cause issues with the rings glazing and not sealing.

Keep flipping and folding the paper towel and soaking with WD-40 until the paper towel comes back out clean!!


Now look in the corners inside the block and in general give the block a good look over for anything missed.

Make sure any oil galley plugs that were removed are replaced.

You can not get your block too clean!!

Good info.
whats this "oomph" tho?
and this isnt a Honda block it has oil squirts at the bottom of the cylinders. what is it out of and do those help with oilying the cylinders better?
OOmph is just a purple soap, like purple power or super clean.

The block is a 2ZZ Toyota engine, the squirters help cool the pistons from under side of the piston.

Thats cool. I seen them used on some over motors making alot of hp from factory. Just never knew if it was really adding anything worth wild.

yes a fair amount of engines have them installed from the factory.

Nissan SR20DET, RB26
Mitsubishi 4g63 DSM & EVO, 4BT11, 6G72
Are just a few I can think of off the top my head

I could swear my b16a2 had oil squirters in it. I even plugged them with the GE kit.
Maybe not an A2, but the JDM B16A block in my garage has them. Surprised Biggie and I.

Interesting. Are those valve clearance cuts in the sleeve? Is that stock? I want to see pics of the head, haven't seen that yet...

Yes they are valve clearances. From the factory too.

Ill check and see if I have the head around. or one like it.

I wrote this up a few years back, so that engine has been long gone, last I heard it had Nitrous and a super charger on it.

Nope, just a basic 4valve DOHC engine.

really nothing all that super sonic about it.

VW/Audi are about the only 5v heads I can think of in gas burning form, there are some diesels that run that configuration.

The 2ZZ is used in the Celica GT, but Toyota also had a 1ZZ and Scion used one called the 1AE(?) in the TC All very similar, most had to do with VVT. All 3 use the same timing chain and gear set, so you had to make sure you used the right timing makes for the engine code.

Well enough.

I do not recall ever having the 5V toyota head in my hands. But good info to know there is one out there.

The 3 engines I spoke of are all 4V DOHC engines and in the same family, IIRC all have the notched sleeves.

BTW Pontiac notched the the block for the valves on some of the smaller displacement V8s

Only the 4ageLU is 5 valves per cylinder.

Regular 4ages are 16 valve, not 20. Including the supercharged 4agze.
