HOW I CLEAN ENGINE BLOCKS BEFORE ASSEMBLY

- IN THIS VIDEO I MAKE PROGRESS ON THE 305 AND LS BLOCKS. I SHOW HOW I CLEAN THEM BEFORE I BEGIN TO ASSEMBLE. IT IS A LONG TEDIOUS PROCESS BUT WELL WORTH THE EFFORT.
HERE IS A LINK TO THE ENGINE CLEANING BRUSHES I USE AND THE PAINT I USED:

Back in the mid 70s I attended the Nashville Auto Diesel College. I went to school at night and worked full time. One of the jobs I had was at Standard Motor Co. My first tasks there was hot tanking the engines when they came in. We did everything from antique Maytags to huge Buda diesels out of river boats.
I got very acquainted with those block brushes.
The hot tank was a huge vat of boiling caustic soda and water. It would take everything off....including your skin. It was a hot messy job. You had to do it well though.
That shop was a full service shop that bored, sleeved, balanced and ground everything on that engine. They even ground camshafts. I learned from the best. Old school guys that knew every trick in the book to make an engine right.
Clean.
And more clean.
There is a stadium where that shop was, and the Shelby Street bridge is only for pedestrian traffic now.
Vernon, Tony, Steve, Slim, they all taught me to take special care and pride in my work, no matter how nasty it was.
Nice work on that block, J.C.!
Cheers

Great to watch someone else with a need for perfection 😊 from start to finish
not perfect but acceptable.
Great video J.C.Smith really enjoy watching you clean those engine blocks. Looked good with a fresh coat of paint. Thanks for sharing Mr & Mrs J.C.Smith.
Very thorough. Well thought out and executed. Thanks
Sahra-n-tuned would be jealous of your work. "Squeaky clean"
👍👌👏 Painstaking cleaning process but well worth the effort. The engine block is as clean as it should be.
A very thorough cleaning job well done sir 👍.
Nice job with the cleaning J.C 🙂👍 The black paint looks great. Take care 🔧🔩
Hi JC thank you for sharing 😊
Now this is super nice !
Have you tried the goodson high pressure oil gallery cleaning system. Much better than the old method of cleaning oil gallerys and cylinders. Lifter bores.
I'm amazed that so many people fail to clean the outside of an engine before taking it apart.
hello j.c & mrs.smith it's is randy and i like yours video is cool thanks and good luck j.c. whit's the clean engine blocks blocks before assembly thanks and ( hello to my best jeff the dog ) thanks j.c. friends randy
What brand wipes/rags are you using?
Can u do this with sludge also ?
😮
Where can I buy engine brushes
Well done.... most just dont grasp the clean concept. A so called ready to assemble hot washed block from the machine shop needs this same cleaning. Not a fan of thread chasers though, a good brushing is usually enough, maybe chevy motors need it.
the thread sealant they use is pretty tough stuff. i use the thread chasers to make sure i got it perfectly clean and will let the bolt toque and torque to yield properly.
Im a mopar guy so please excuse my ignorance on the 305. You say sealer.... open to the water jacket the reason for the sealer? I seen a guy putting what looked like red lock tight on some of his bolts so im thinking maybe so. @@j.c.smithprojects
many people use a liquid thread sealer. it can harden in the threads. i use liquid teflon in many situations.
Is the crud in the bottom of the head bolt holes locktite?? I know GM uses a lot of locktite sealant on their bolts
no. it looked to be a thread sealant. i assume the rebuilder uses it on all the head bolts as their procedure.
J.C, can you see if your snapon guy can still get that blow gun? I can’t ever track down the local one, been trying for months.
I need a couple of them
they dont sell this one any more. it was a safety issue i guess.
Hey, i have the exact same pressure washer as you... LOL
Hey JC , my car needs a bath. Been outback Australia for a few months. Red dirt everywhere. You done such a nice job on that block I thought you may be interested? Hello Mrs JC.
not so much...my wife is the vehicle cleaner around here.
Hey jc is the isc Cummins 8.3 any good
I think it is vastly over rated. reliable but over rated.
be careful and check your tap carefully, a long time ago i did that and the tap was removing metal which means it was enlarging the threads. you said thread chaser so that means maybe not a tap. a tap would be ok if it isn't removing metal just rust and sealer.
Detailed clean, I would have gone with a yellow or light blue for the block to help see future oil and water leaks and see bolts easyer if work was needed.
these dont leak like the old small blocks. besides its easy to spot a leak on any color engine when it is clean.
Procedure:
*Threadchase and blow out debri
*Wash with pipe cleaners and hot soapy water
*Power wash every orifice
*Check Cam bearings very carefully for debris and check oil passage alignment with a mirror.
*Check all surfaces for cleanliness and dryness with a lint free cloth
*Spray everything thoroughly with residue free brake parts cleaner
*Tape off and paint
*Re-oil and start the blueprint/ build
Did I miss anything?
Thanks for the video!
15:45 two coats of primer, 2 coats of paint .....LOL
im nothing of not predictable....
@@j.c.smithprojectswhen are those t shirts coming ? the one that says: I am not a welder .... I want one of those too
Does anyone know why GM started painting the engines black?
Cheap
GM started using Chevy engines, Buick, and Pontiac engines in whatever car back in the late 70's early 80's and there was a big stink made about it. GM stated it had a right to put in what ever engine was economically feasible. More or less big cars got Chevy V8s, midsize cars got Buick V6, front wheel drives got Chevys 60 degree V6 and Pontiac 4s. After that to reinforce that it was GM Engine, not a Chevy, Buick, or Pontiac engines they were painted black. Also in the late 70's before GM rationalized it engines there where more than a few weird ones. My Mother had a '79 Grand Prix with a Pontiac 301, and not all Trans Am cars got Pontiac Engines, some got the Olds. 403. But by the 80's I think they were all painted black. That Firebird Esprit that Vice Grip Garage just rescued was a Chevy 305.
So the oil leaks would be less noticable
I was just about to comment that I used a wire brush to clean off a lot of sealant and then you brought out the wire brush.
You're a very thorough person.
At what point do you stop second guessing yourself?
never. if i stop, i dont learn. if i dont learn, i dont get better.
@j.c.smithprojects1769 I was literally going to comment something similar
The difference between a great tech and a good tech
Great tech thinks he is only just good
Good rhinks he is great
Great always asks questions and trys to improve
Good knows everything and stops learning
At what point do you move out of your parents basement?
After you sell the car lol
And there is 2 different blocks used in this video because??????????
10:18
you miss these details when you skip around and dont watch it all.....
Well, you lost me there. I was watching a small block not a LS.
