Heavy Oil Leak Bandaid Failure. But Why Did It Crack? 13 Ford 350 5.4L

[@NickMyers1]

Repaired a crack ages ago on a Lincoln Town Car 4.6 - block cracked from someone running straight water in cold of winter - but it cracked in the valley of the engine - bought car cheap like that. Removed intake. drilled holes to stop crack. grinder to clean area up. sanded with coarse grit. used alcohol or something to clean area. packed with JB weld. Fixed. Drove car like that for many hundreds of miles no issue. Trying to weld a cast iron block is a nightmare.

[@chuckvoss9344]

Yes. If it was MY engine ... die grinder, brake clean then JB.

The mystery of the cracked block

[@n1umj]

I knew a guy, he raced at a local short oval track who had a similar crack in the block. He couldn't afford an engine so he did the JB weld thing. He figured it was worth a try but never expected it to hold the following race week. He actually got a season and a half out of it before he bought another guy out with an all round better engine. For all I know that engine is still out there as a spare to this day, I'll have to ask him next time I talk to him. He could not believe it held but I've seen so much worse. Knowing him it's either still his spare or one of his friends has it.

[@donmunro144]

I've used a product called belzona with success. It's expensive but works great. In fact, cat recommended it for cylinder deck repair on a 3512 engine that I used to maintain. As far as I know, it's still there.

[@iFixJunk]

I'm familiar with Belzona, but not for an application like that. Their tech support will guide you through certain..."off-label" uses, though. It IS expensive, but if you research the product and learn how it came into development and use, it's pretty impressive.

[@donmunro144]

Another option is called Lock-N-Stitch. I fixed a cracked boat engine 4 years old. Boat gets used every weekend and hasn't leaked a drop. A little labor intensive, but way less than an engine swap

[@robertpulliam9973]

I had a 1956 Allis Chalmers tractor that I was rebuilding, all new parts, my brother-in-law decided to “help” me with the assembly of the engine while I was at work. Service manual was right there but he knew better and assembled the engine like a SB Chevy, WRONG!! The wrist pins “floated” in the rods and were bolted to the pistons, were Siamesed on the crankshaft. Later after everything was done he started the engine and immediately heard noises that it wasn’t supposed to make. Upon disassembly the number 3 cylinder was found to be deeply scored from the wrist that was assembled wrong. Removing no.3 cylinder assembly, cleaning the liner thoroughly I mixed enough JBWeld to put a light coat in the groove to let it cure overnight. The next 2 days I did the same until I had built it up above the liner surface beside it. I then slowly started to hone the cylinder until there was nothing but a dark line in the bore, you couldn’t feel any imperfection. I then reassembled the engine according to the book while dear brother in law watched. The repair was still holding solid 13 years later when I sold the tractor, I became a true believer in JBWeld at that point. Point is never ever let a brother in law work on anything you really need.

It's pretty amazing what some good ol' JB Weld can do for a fella when it's appropriate. Good call not using it on this rig though, Kenny.

[@joemuncie9187]

I've had good luck with JB Weld

[@mikeburdi3464]

Get the block properly welded. I can't see much value in the vehicle at over 200, 000 miles so I would go the cheapest most reliable route possible I hope you and Mrs. Wrenching are getting much better kenny!

[@bigdaddymak1439]

Just flex seal it Kenny 😂😂😂

[@robertdiehl9003]

Hydrolock diagnosis. Awesome find. Makes sense since liquid can't be compressed.

[@rharris7635]

Definitely safety first, $ second, especially for a business and children.

[@Failure_Is_An_Option]

Awwww... the chilren... Always hide behind the fleshy meat curtain that is the chilren...

[@johnknox5692]

tig weld with silica bronze, or alum bronze, its rated at 40000-70000 psi., easy place to get to wide open,

[@scottymoondogjakubin4766]

Im buying stock in JB weld after seeing that ! 😛

[@barmanvarn]

At least they didn’t use spray foam LOL

[@lynnlutjen3819]

If I was your customer I would have the JB weld trick done and send it to the auction house. 200k it’s on the down hill side of life 👍👍

[@glennfields8121]

This was a good find my brother. Keep Wrenching brother.

[@richardroach9030]

At that point, go for the guts and glory drill that spot out re JB weld it called it done.

[@maraudersr1043]

Weld it shut!

[@dondownriver3464]

Heat that part of the block up and reweld it.

[@mikeburdi3464]

@@dondownriver3464 That's what I say. I have seen many blocks welded (properly) and never have a problem.

[@paulschlobohm7226]

Your a good man. Good decision

[@grominwithrob1339]

Of course he used silicone, he was all out of grape flavored big league chew. 😂🤣😂🤣

[@maddawgnoll]

I was walking down to my shop when i read the thumbnail writing and nearly tripped from shock at what it reads

[@terryjohnston7162]

Clean it up add another layer of JB and go another 240

[@iFixJunk]

That's what I was thinking 😂

[@Toolaholic7]

I always make sure there is no coolant and oil in headbolt holes in the block cleaning them out good.Know very well learned fluids take shape they are in and do not compress back in school

[@82_KID]

Shout out to that AX4S trans! Our Taurus had one of those. Nice. 1:13

[@bricktop7803]

Yup - they got a cousin called Wayne who said he could fix the block with JB Weld.....

[@allynhowell2006]

The customer needs to have a person JB weld it and trade in at a rip off car lot as quickly as possible.😮 I'm guessing it's a factory void block,I've seen before. Did you do a oil pressure test ?

[@peterbenson3776]

Seemed like a good stop-gap considering the miles /age of the engine.

[@donniee1934]

Don't JB it. Clean it good undercut the crack with a die grinder and use Belzona. Past experience with sealing cast-iron steam jackets on heat exchangers. 100PSI steam pressure and no leaks. Hope you and Mrs. Wrenching are doing better.

[@bigbill709]

Thanks Kenny keep wrenching

[@dennisvandergriff7757]

Thanks sir interesting vedio. 👍 I put new plugs and plug wires on 217 yukon denali. I'm 67, never seen or heard of this before, as one of the spark plug wires would pop, or unclip as soon as you remove your hand from the plug wire. I had to go back to GM dealer to get that plug wire replaced. What is up with the quality parts now days from MEXICO. 😢

[@michaelmartin2276]

Heck with the age and miles on this van I'd clean and sand the Crack as good as possible and jb weld the helloutta it !

[@wesshofner9495]

If it was mine I would clean it down to metal and weld it.the motor sounds good.

[@keithrimmer3]

Could you clean it up and braze it up?

[@RussellBooth1977]

I know about 5 years & 8 months ago when I removed the cylinder head gaskets in my 5.7 litre Chevrolet LS1 V8 engine in my Holden Commodore I blew any engine coolant which was in the bolt holes out with compressed air prior to fitting the cylinder head gaskets & new cylinder head bolts. Apparently what happens if you don't do that the water which gets trapped underneath the cylinder head bolts boils when the engine is hot & since the steam generated has nowhere to go it acts like a pressure cooker then it can crack the engine block. I would get the engine block welded by someone who can weld cast iron,I certainly wouldn't use JB Weld on a customers vehicles engine although the metal reinforced type of metal filler may do the job, it's just JB weld doesn't seem to do well when the engine gets really hot & it's exposed to engine oil,I mean if it's used inside of the engine. I know that I cracked the right hand front corner of the aluminium alloy oil pan so I got a welder to TIG weld that corner of the oil pan,some people do use JB weld to try and fix that but I wasn't confident that it would hold & I didn't want to get underneath the car to rip the oil pan off again to fix it properly the second time. The car was unregistered at the time & I didn't want it to fail the blue slip inspection which is required in New South Wales in Australia whenever the car is to be registered & if it's been unregistered for more than 3 months. They're also required if the engine is replaced to make sure that the donor engine isn't stolen, it's required when a change of engine number needs to be lodged with the Roads and Maritime service !

[@CajunShrek]

Sand and JB weld

[@gerardtrigo380]

Back in my day I saw people weld cracks closed on cast iron engines. I do not know if that would work on aluminum block engines or if it was even feasible.

[@scottwhitcher265]

It's easier to do a quality weld on aluminum than cast iron but both CAN be welded by soneone who knows what they're doing.

[@mackendw]

could they remove that silicone, clean the metal off good and grind the crack a bit and weld it closed?

[@mattbrown5511]

Ford's 5.4L strikes again.

[@InTime-x3j]

Darn good theory. I would have guessed a junkyard engine.

[@btwbrand]

Clean it off, grind it, braze it, paint it. Common sense. It's literally just metal. It's always fixable.

[@whiskeyfamily6717]

I would jb weld it agin run it tell it blows then replace engine

[@mtut]

Whatever they used to band-aid it is part of the equation. You'd pretty much have to take it off to see what the metal looks like. With these monkey snot repairs, the adhesion to the metal is never 100% and oil can travel under it pretty far from the source. That would be my biggest problem agreeing that the block is cracked. With such a large patch on there it's hard to definitively rule out the intake and head gaskets.

[@oldbiker9739]

is it time to stich that block ? I have fixed leaking oil gallery plugs and oil gallery pipe plugs , but a cracked block NO I haven't .

[@seanmoore1809]

I worked on one leaking oil just like this and leaking from headgasket there is oil pressure supply feed there

[@ewconway]

Who the heck JB Welds a cracked block? Incredible

[@carlm2590]

A person that does not have the money for a new engine

[@glennpham2763]

Is that wrong?

[@nigelstewart4736]

Engine runs good. Clean that crap off and weld / patch it up.

[@RustyorBroken]

I once repaired a broken crank using nothing but paper mache and Popsicle sticks.

[@Uber_Soldat]

Isn’t it possible for a TIG-welder to fix that crack?

[@paisleyprince5280]

Stupid isn't stupid if it worked.

[@Sctronic209]

I would have it welded.

[@RobertYonng]

It can be fixed but is it worth it unlike the Indian engine block with a broken main in the block. 😉

[@ginog5037]

Take it to a professional welder or clean it up and JB weld it. With that milage and carrying kids, scrap the van...

[@karachaffee3343]

Trowell in another layer of Doc Fonebone's Block Mend-R and all will be fine.

[@DavoShed]

That’s the second worst silicone job I’ve ever seen. 🤠 It’s got a crack in it. Unbelievable. If I did that I’d be worried about “repercussions” if you know what I mean.

[@WrenchingWithKenny]

Absolutely agree! Thanks for watching the channel & keep wrenching 🔧

[@fubartotale3389]

Jeez, some people right? Everybody knows that's what spray foam is for!

[@donaldboley771]

That's not the only leak.

[@82_KID]

J-B Weld that thing, let it harden and drive away.

[@teddymullins3706]

Could a guy take And clean the area real good And weld it with a nickel rod if that's cast iron that might work ,I welded cast iron with nickel rods before and they held

[@Failure_Is_An_Option]

Where is this cast iron you speak of...

[@teddymullins3706]

On the exhaust manifold

[@bigbill709]

Another vote for weld err up .

[@craigdowney6438]

my dads car had an exhaust leak. he insisted that the gaskets were in perfect condition so to "fix" the leak, he put JB all over the edge. it actually worked for about a week but then slowly started melting. he still believed there was no problem with the gaskets and that car went to the crusher with the original gaskets.

[@mandragor85]

i think that goes like a hidden fault if he did buy it like that...

[@mandragor85]

yeah do those things on your own car then if something happen only you are getting hurt if you do it on someone else's car and they get hurt because of it then you're liable for it

[@robertdiehl9003]

I almost guarantee that Permatex gray high temp sealant was used That product is absolutely junk beyond belief and doesn't work . I used the same stuff for power steering hose and made a huge mess.

[@tombeilman5579]

Everybody knows you use spray foam on an engine

[@dennisrutherford6973]

Wow I've never seen that before....what in the world where they thinking

[@OCHO.008]

i get dirty too, and very surprised to see this on such model, these china metals are tricked up brother, also, prayed for miss wrench here, love cars, i just do not work for any 🔩. enjoy the fun!
