GSX Block Prep Part 1 [1080HD]

Preparation for powder coating and Glyptal application. Audio track is an original performance by Rojo Del Chocolate.
My block is being powder coated rather than painted. It's just something I do. The GSX had it on the last block so it's getting it again.
Since the tools are so similar and the mess is the same, I'm going ahead and preparing it for the Glyptal application as well. These 2 coatings will require being baked separately. The powder coating is baked on at a hotter temperature than the Glyptal, so it's going first.
The surface preparation instructions for Glyptal is as follows:
Surface to be painted should be dry and free from dirt, wax, grease, rust and oil. Remove all grease and oil by washing surface with mineral spirits. Wipe or scrape off all loose dirt, rust or scale.
The last sentence is what's covered in this video. The 2nd sentence happens next (although it's already degreased), and I'll get it back from powder coat with it in the state described in sentence #1 completed. If following these instructions to the letter of the law.
Second and third opinions in... the main journal is fine.
You'll notice that I didn't coat the main caps, or "suitcase handles". I'm not going to. You bang around on these installing and removing them, and I don't want to risk chipping them once they're coated. They're below the windage area, and there will also be an un-coated main bearing girdle down there.
This video covered 25 hours of actual work. Yes, I kept changing into the same filthy clothes every shoot because I wanted it to look consistent. You have to take your time doing this kind of work, and be VERY VERY CAREFUL! If for some reason you're crazy enough to attempt what I do in this video, you do so at your own risk. This is an elective treatment that I've never done, but I am by no means the first person to do it. I'm learning about it just like the rest of you.

When I'm stressed and anxious I watch this channel

[@warusweims]

It's rare that I see someone other than myself take such care for a project. I'm speechless. Awesome videos and commentary. Very informative and balanced. Just great.

[@ferrelx]

im surprised your not aware of the 2 things you got when you did this procedure..because you spoke of it in your "7 bolt diagnosis" vid..cleaning this block up in the manner you did with that conical carbide burr was just like peening the block to relieve internal casting stress..making the block more resilient..removing the flash and casting burrs removes a lot of internal resonance points that can lead to block fatigue/fracture and other issues that you mentioned in your other vid..so kudos to for taking the time to do this..dont beat yourself up on the time it took..you got more out of it than you realized :) btw i like your style..these vids are worth watching..

[@inspetorgambiarra]

Gostei do comentário, aprendi mais um pouco.

[@tommybaker4330]

When grinding in the bottom end of the block, leave the old bearings in place. They will give you more protection than painters tape and you won't have to go stand in the corner. Don't have the old bearings? Go on ebay and buy the cheapest set you can find. There are always cheap knockoffs from China that OEM fanatics would never use and are cheaper than factory or high performance shops offer. I know its messy, but sand blasting will give you a nice"tack" to apply your glyptal to. Just be sure to blow all the sand out.

[@olipirard]

I do love your sense of humor. You make your videos with your soul and your heart. Thank you.

[@retroguitarmaster]

I was biting my nails when it happened, thought after all that preparation it was going to be ruined, that tape saved the day

[@ebailey95]

Jafro, you and your GSX are such an inspiration to myself and many others! Your level of detail and craftsmanship is unlike any other. I love your videos and I hope someday my GSX will look anything like yours! Thanks for your Videos!

[@TPGDSM]

I'm glad I came across your channel. Great info and advice. 98 gsx build in progress in NY.

[@xtra1234]

Good Job. You go beyond and above anyone i have seen.

[@speedskiff2]

Nice videos. To some doing a prep, this is known as "therapy". Feels good taking pride in a job well done. The only real pain comes when engine eventually blows up. Didn't watch all videos but while you have grinder and files out, journals and caps should be relieved. Before Glyptal came along RustOLeum red primer used to coat innards. Glyptal also works good preventing creep with threaded electrical connections. For some, building a small extension the size of a small pallet outside on back of building to house compressor cuts noise and frees up space.

[@nullanon1259]

Cool video. Nice commentary along with a little humor.

[@jesterkid99]

You just keep giving me more and more ideas for my build thank you sir

[@markphilpot4981]

Bad Jafro! Put him in the iron maiden! Excellent!🎸 It’s hard when you jack up your own hard work, but the smart ones learn from their owned up mistakes and live to fight another day! Gotta have some fun! As Tony Montana said, you got to get some fun in your life!😲😊👏🤘👍🏻

[@OGZeroLyfe]

yeah its best to leave the bearings in place when you are going to be grinding around inside your block

[@zaspitfire]

You are great dentist material. The way you handle all those cavities. The patience. The care. :) Great stuff :) Keep on going :)

[@smayhan09]

That Was The Most Relatable Monologue To Screwing Something Up While Building Your Engine. You Mentally Just Put Yourself In A Corner And Call Yourself A Bunch Of Names. Many Of Us Have Been To That Corner At Some Point.

[@rezneba101]

Samuel Mayhan Why Do You Put Capital Letters At The Beginning Of Each Word? Wanting To Sound _EPIC_?

[@TheFunkyKettle]

Wow, THIS is commitment.

[@awdx4g63]

Thanks for posting excellent 4g63 videos. I have a dead 2G on my driveway and will resurrect it somedays with the help from your excellent videos. Thanks x100

[@PowerDynamix]

Not sure if anyone posted this. I didn't go through all the 100 comments. You could put a set of old junker bearings in the block. You can even put the cap side(bottom) ones in so it would cover up the oil passages to prevent shavings from entering. You would have to try pretty hard to gouge those down to the main journals vs a thin layer of tape.

[@stevesolo16]

Those rough areas is sand that stuck into the corners when cast. Yes, it comes off so it doesn't fall into the motor during assembly.

[@351cleavland]

When the music qued my booty began to shake and wiggle, against my will, as though it were possessed!

[@mbarizia]

:) great response! thanks for sharing your experience and hope your are doing well with your rebuild !

[@jononeil500]

You make great videos, Mr. Jafromobile. Thank you.

[@Speedie15]

I cut up old beer cans that are somehow always around the shop and tape that over bearing journals and bottom of the cylinders so I dont make mistakes while grinding. It offers just enough protection and dont get into the way

[@TjeZz84]

Love your vids Jafro :D im building an 4g63 myself, and keep folowing you videos to get the best out of it :D looking forward to assembly and glyptal :D thank you for taking all this time to make these videos. its a pleasure watching them... :D

[@adamsholzhaus8196]

Advice: take a pair of old journal bearings and kinda glue them in place (RTV) with the caps on and BAM, heavaly protected journal surface.

[@israelmanriquez9896]

Very interesting your video Sr. Chocolate. Thanks for this video.

[@07wrx530]

Can't wait for next video I'm luking forward to watching u put this togeather then in car and then it run

[@paulalejandro6656]

I have rebuilt hundreds of these motors and 4g64 in forklifts. Loads of torque and they last a long time if their taken care of.

[@215alessio]

I don't know if internal coating is necessary since the oil will prevent the inner from rusting. altrough smoothing surfaces from impurities inside, specialy the oil channels do great things to the good function of it as a whole. faster lubrification does miracles

[@sweenep86]

There's more prep you can do to improve things like countersinking, bottom tapping head bolt threads, chamfering all edges if the mains to remove stress risers and chamfering the bottom of the bores so oil isn't shaved off

[@XSTAYUPX]

Beautiful . Cant wait to start my racecar build.

[@larryhazelwoodjr7605]

This was amazing! Awesome vid and info!

[@st3al09]

Awesome work!

[@markvillafranco]

awesome vid. it nice to know even the pros can miss up every now an then lol

[@sergey3429]

You are crazy! The god of mashine work with 4g63 :)

[@SushiPac]

Very very nice work

[@duncansport]

Glyptaled my 4G54 block during the build. The inside of these mitsu blocks are fairly rough, so any improvement witht he smoothness helps.

[@1elAguila]

simply ameizing details work amigo

[@arttohickko4255]

Japhro: I just purchased my 5.4 Ford Engine Today!!! It came with a water pump, crankshaft, two cylinder heads and 500 extra Bolt systems!!!

[@mechguy83]

Looking forward to the future videos!

[@glempa5]

When you hit the journal i got that same feeling you get when you mess up something badly yourself, it went something like this: Did he hit... Did.... NO NOT THE BLOCK, FUCK!

[@randaddy2000]

Thank you for posting these crazy dsm vids. See ya at the shootout!

[@marglar1982]

No, It's the bug, once you start shining metal, it's catching...... I got it bad, but I don't have blocks or heads to port and expensive tools...... Ryobi sandpaper, and some black ruge are cleaning up my oem valves for a rebuild

[@mkalb4g63]

If there's ever a next time, some old main bearings would make for supreme protection from the power tools.

[@Jafromobile]

Yep. There's been a next time (current video), and this time I actually had a set of bearings to put in it. When this video was shot, I didn't have any except for 7-bolt bearings which are far too narrow to offer any protection.

[@ej20tnz]

Should leave the old worn mains in the journals to protect them, ditto with the oil squirter bolts and washers

[@Jafromobile]

Didn't have them. All I had were 7 bolt bearings and they're a half-inch too narrow for this. Since my Hyundai blew up (it's 6-bolted), I have a set now... but didn't have it at the time.

[@MichaelSmith-nd4rr]

It will be ok, the bearing covers it

[@YOLORACER]

Good choice of music.

[@MCRmechanic]

Would have been interesting to see the before and after weight of you block from the prepping process.

[@Jafromobile]

+MCRmechanic And dangit, I only bought a 110lb digital fish scale just this week.

[@MCRmechanic]

+Jafromobile those are some big fish! Haha

[@Jafromobile]

+MCRmechanic Man, I hope I get that lucky! lol. If I could just catch one 100lb croaker, it would save me an awful lot of time this season with filling my freezer.

[@dc5000123]

Great work on this video !!!!! I do question whether your tools like you or not. LOL !!!!!

[@zx8401ztv]

Ha ha i like the standing in a corner, ive often ruined things and felt that way, doesnt a mistake make your heart drop, that horrible feeling. "Dam it was going so well" Never mind, not the end of the world :-)

[@stevesolo16]

Did I hear you correctly, "it took over a month to complete the block prep?" That's insane!! And you didn't even chase the threads.

[@nezerac]

Feels like I just watched Heisenberg make a batch of Blue Meth :D

[@malventano]

How can I Rojo's tracks? I'd kill to be able to listen to them while doing my own wrenching!

[@ucw458]

I remove the flash on every block I build. Inside and out. I find it unsightly too.

[@DJDevon3]

Now we know why such careful grinding is required. Once lapse of focus is all it takes to screw up big time. Let's say that it did put a small gouge it. Why would that make a difference since there is a large journal going to be mounted on top of it. The shaft rides on the journal and not that surface. Obviously you don't want any scratches but I don't see what the big deal is about for something so miniscule. Only thing missing was a homemade dunce cap. That would have been funny. :)

[@robl1417]

can you measure your cylinder bores bottom middle top? then bolt the head on then repeat the cylinder bore measurements from the bottom of course to see if bore measurements have changed ??

[@Jafromobile]

I'll do that on the next build just so I can end all the discussion about it! I think that would be a great idea for a video, and I thank you for giving it to me. It's almost like a Mythbusters episode...

[@jb2zero0six5]

Is the fluidampr your answer to not having balance shafts and a lightened flywheel?

[@mz-khan]

Jafro, could you do a video on how to properly mount an engine on an engine stand? Thanks.

[@w43558]

Hey have a question are all the timing marks on a 4g63t 6 bolt half to line up even if the engine is built? It kind of a stupid question but I wanted a second opinion.

[@w43558]

Ok thank you. Your videos are always helpful

[@TheSomedrewguy1]

Thanks Jafro, another great video, I like the music btw.

[@tonkatoytruck]

I noticed you are using your air die grinder or two. Did the electric Milwaukee finally "die"? Or was its size restrictive?

[@gfienkiller11]

always love your vids jafro. your awsome

[@07wrx530]

Awesome as always ))

NOOOOOO!!!! I was just thinking man I hope Jafro doesnt hit a main with the grinder and BAM. I thought i jinxed it! I hope its all good buddy!

[@theratinaCage]

Yoooo!!!! Picked up my 2g in 2011 and blew it up in 2013. I’m fiiiinally rebuilding this thang after spending the last 6 years buying parts little by little over time. I WILL be giving it the jafro level of attention, minus the coatings. Should I post the build? Anyways. Been watching you’re videos for 6 years and I’m excited to get somewhere!

[@bittainment5995]

What buffing tools you have been using. Types of grinders and its brushes. What are the grades.

[@darius240z]

once I saw the close up of you in the corner i lol'd so hard

[@juanyboo12345]

THAN YOU JAFRO !!!

[@ltoperater]

Doing this times 1000 on my next build. I want it to be smooth as well you know.

[@brandonhaywood3391]

I'm a newbie my bild is a 2g 4g63 gst 9.1 rotating assembly arp all the way around super damper map sensor 4 bar fuel regulator coil on plug ar/30 turbo stock boost stock ecu a lot more. so can i run a 9.1 on a stock ecu

[@sirbow2]

i got a question for you jafro, if i may. for people doing the 4g64 7 bolt block with a 4g63 7 bolt head swap, does a 2g 7 bolt complete gasket / seal overhaul kit work with the bottom end, or would we need a 4g63 head kit and a separate 4g64 block overhaul kit?

[@sirbow2]

[@Mebob2001]

You my friend need you head checked for going that deep with a dir grinder xD haha but doiing inside the block takes it to a whole new level man, but your engine do whatca want im here to watch and hit like!!!!

[@mightyeagle]

Maybe use a plastic bottle or other of the same outer dimension as bore of crank journal to protect instead of tape

[@TheGixxer6969]

do you know that will make the block stronger to less chance of cracking under power and will help oil drain i have been ding that to all the engines i have built sense i was a kid my granpa should me that

[@Oranger37]

it was like watching Picasso destroy his painting 95% of the way through because science

[@marijanabrezic8854]

8:42 i expected there to be a scene where you're ruthlessly throwing the block in a container.

[@Xantho32]

Or could’ve kept the old main bearings on as protection

[@eddieds312]

my engine block has rust inside the coolant passages "is it junk" ?

[@gidb]

8:42 lmbo your the best!

[@gidb]

love all your videos but this one takes the cake!

[@jakubpolomsky]

the music is awesome!!!

[@kfjfjfjewlsls]

Hey Jafro! Does that engine have hydraulic valve lifters? Would be nice if you did a detailed video, i've been battling with my mercedes.....

[@pablomini6155]

big fan of your work and attention to detail. question, what size air compressor / tank are you using to powee that rotary tool ? and what would you recommend for a beginner tryna do the same. thank you in advance :)

[@Jafromobile]

+Pablo Mini It's a 40 gallon Central Pneumatic upright. In other words, Harbor Freight. They used to make this 40 gallon 240V model and I bought it on clearance for $399. No coupon. 110 PSI. I wanted it because it was 240V and because it had a twin-cylinder oiled compressor with a 14.2 CFM recovery rate. I've kept it oiled, but it does nowhere close to that anymore. It's doing about 5 or 6 making banging noises.. It needs work. I've done some grueling jobs on it. Using it Jafro style made it only last about 7 years, but divided up on all the jobs it was well worth it. My point with it was to demonstrate that it doesn't matter what you spend if you can just find one with a good recovery rate... but with cheap tools, you're going to get what you paid for. It's loud. It develops leaks from crapmetal regulating parts, has never been well balanced, and eventually shakes itself to pieces. At that price, who cares? It's still going and I'm going to run it to death just like I did with the Hyundai and the GSX. I would have traded 2 or 3 CFM for a whole lot less db. Look up the Airmax HRA25-12 Air Compressor if you've already dropped anchor and can afford it. They're stupid-expensive bushed and balanced, 25 horsepowered, 208, 230 or 660 VAC 3-phased, magnetic started, self-draining, low oil emission workhorses. They will last you a lifetime and service parts will be available forever because it's a medical-grade unit. It's a 175PSI 90 cfm 125 gallon compressor that runs so quiet you can mumble a conversation to someone half-way across the shop and they will easily hear you. You will hear them mumble back even if you're standing right next to it. It's amazing.

[@Themayseffect]

I'd be too tempted to do a stage 10 weight reduction on that block by cutting out any structural waste lol.

[@denisecoss7607]

What is the point of doing this

[@bullet2068]

Better oil flow

[@kyleallen3857]

bullet 206 Supposedly And only in older very pours cast iron blocks, if at all

[@ahmedsbedair]

good video

[@paulsay7861]

I have a question , I blew my motor , I just got done building here soon . I bought a new oil cooler . Do I need a new oil pan and oil filter housing , since I had shaving in both ?

[@Jafromobile]

That all depends on how well you're capable of cleaning them. Take the OFH completely apart and clean it, and you should be fine. Look up my DIY parts washer video.

[@BoostedCajun]

Will you be doing a segment on wiring a 4g63? Being your going to swap one into the Colt, I assume a video of that content is a must. All these video are a great!!! Thanks for all the info as usual. Also where can I acquire the Caps software you use?

[@RuthlessZabusa]

Hey man, I just want to thank you for sharing all this knowledge with everyone, It must suck to have to work so hard on the car, and then even harder on documenting it for the DSM community. I'm rebuilding my drive shaft in a few days. One question, If the Lo-bro boot is in good shape, can I reuse it?

[@golconda86]

Hi jafro! What type of air compressor do you use for this job? Thank you

[@djeletropopstarify]

how would aluminum block would react with heat cycles with powder coating owen heat's?

[@tonkatoytruck]

Do you have a leak down test video? I have looked all over You Tube and they all leave a lot wanting.

[@donrosscojoe5014]

Dude....... Theres a fine line between being a perfectionist, and having OCD, taking the burs of with a grinder shouldn't take more than 20min, but hay, I'm not hating on you, you'v got the same passion for small turbo cars I've got and I'm sure it turned out to be a sweet little engine, keep wrenching.

[@Jafromobile]

I'm not just taking the burs off. This is stage 1 pre-burn-off oven preparation for a Glyptal application and powder coating. The car this engine is going in is an 8-time trophy-winning show car. The judges are the OCD perfectionists and I'm just ensuring I stay a step ahead of them because I'd like to someday put this thing back in the show circuit, even better than it was. I'm trying to raise the bar on myself. I learned a lot from the previous powder coating on this car's previous engine. I found flaws that occurred from not doing these kinds of treatments. These treatments are permanent so I'm pushing myself for the absolute best results possible. What I am guilty of… is having done something and conquered it once… and then pushing myself to do it even better. Even in cases where my goals aren't visible or tangible, I challenge myself like this in *all things in life*. I always strive to do better even when I've left the competition in the dust. Once I get around to assembling this monster, you'll agree that it's the most beautiful engine to ever have its entire assembly filmed and uploaded to KZbin. My efforts will only add to the car's character. It's not about me. It's for the car, it's for the judges, and it's for the fans viewing it right here on KZbin. :)

[@donrosscojoe5014]

+Jafromobile Arrrr it's going on a show car, now that makes more sense to me, Iv only seen 2 of your other vids, the tear down with the spun/screwed bearing, and that coating inside the head dose look amazing, if you could engineer a viewing window into the rocker cover or get a clear plastic one made somehow. Yeh don't mind me man, that comment was just a light hearted dig at the most epic de burring (I know it's not that) I'v ever seen. Hope it all comes together nicely, with the attention to detail in this vid I'm sure it will.

[@vinnie4g63]

Don Rossco Joe yeah it's for a show car or whatever but do yourself a favor and watch some more of this guys videos. it's far from all show no go. I am always big time blown away by the amount of knowledge this guy pukes out and the details he goes to building a car. specific knowledge of topic here is by far better than any other you tube channel hands down.

[@Smedleydog1]

He must have removed 5 lbs of unneeded material, for performance it is worth it.

[@iconone5]

I love watching your videos! Any idea when the next one will be uploaded? You are a dsm god!

[@mbarizia]

good job! preparing block is one of my favorites part on building motors! what would you use to pressure clean oil galleys? diesel?

[@uprise51]

Hey Jafro, love the work man. I just had a quick question on where you send your block for powder coating any place special ?

[@sirbow2]

I wanna be just like jafromobile when i grow up hahahaha

[@marcju1ce]

I am watching all of your movies but am curious as to this magic blue tape you have. What is it?.

[@Jafromobile]

marcju1ce It's plain old blue painter's tape. Nothing really spectacular about it. It's an acid-free masking tape that comes in different widths and gets used for all kinds of stuff that it's not made for in my garage. ;) But who's to say what we're supposed to do with it? It's a free country.

[@Walterronny]

time you prepare block, time you almost get block builded, why didnt clean it using ultrasonic machine?
