Very nice! I’m …
Very nice! I’m working on a set of 3.8 SC heads right now.
you can only safely …
you can only safely deck a head so far before it becomes too weak to withstand the pressures. this was probably way too deep for that.
Why not just mill …
Why not just mill it and then use a thicker head gasket ?
lol what?
lol what?
u cant even tell it …
u cant even tell it was welded…very nice!
very well
very well
hahahahhahah
hahahahhahah
Very nice finished …
Very nice finished result. Is that cheaper than just getting a used head?
That man knows what …
That man knows what he is doing!
Nice job posting the vids, good opertunity for outsiders to see how it’s done:)
Its awesome how at …
Its awesome how at 2:00- 2:01 the weld bead changes from one pass to several at the flash of the camera.
John… Running …
John… Running water only in the eng will cause the steel in the head gasket to “rust” and thus causing this problem with the aluminum….But you already know this..i see this all the time liveing in the redneck state of alabama where they think antifreez is the devil..lol
my point precisely …
my point precisely lol
well sin its …
well sin its recorded on a cam you dont realy get the UV
yes it could.. if …
yes it could.. if it was actually UV light..
ok your good …
ok your good at what you do I respct this 1000% but can aluminium engine block be fix like this becuse I have a 4.6 dohc that have two broke’in rod and to hole on both side of the block in the very back #7&8 or can i use’s sohc block with the dohc head am low on cash and my warntty is bs and insurance is bs also so in short i’am f**K big time
fuck i love the …
i love the fact u show ur self welding it could make people blind bwauahhahaha
nice job on repairs
nice job on repairs
3.8 fords NEVER …
3.8 fords NEVER have any problems lol….. they kept my old shop in business
I’ve seen that you …
I’ve seen that you – apparently easy – TIG-weld Alu blocks. How durable is this repair and are the “additive sticks” (I can’t recall the proper name) used in the welding of a special sort for that type of aluminium, used for engine blocks ?
I ask because during the 10 month welding period I had I heard that Alu-welding was the most difficult and prone to break from heat-stresses. Glad to see that it is possible!
As far as I know, …
As far as I know, salt water will make aluminum rust like crazy. I wonder if it’s possible to anno an engine block. That would be something else
Yes, filling in the …
Yes, filling in the )-ring grooves can be done, I have done several heads including Boss 429 heads w/factory O-rings. Not cheap, but very doable.
Thanks for …
Thanks for answering
Could you use this …
Could you use this same process to fill the space where O-rings were previously in the deck of a head? I ask because i have a 4G63 head that has been machined to accept large O rings to run a copper head gasket, however i want to switch to a MLS, would it be possoble to remove the orings and weld it up?
Aluminum doesn’t …
Aluminum doesn’t rust in the normal sence, it does oxidize and corrode due to the chemicals in the atmosphere and in the radiator in this example. Heat and water/coolant w/degraded gaskets will cause this type of damage. Aluminum acquires a layer of oxidation about 1/2 hour after casting that retards further corrosion. The chemistry of aluminum can also be modified to increase corrosion, but after time they all deterrioriate. Thanx for the comment/question.
JE…
How can this happen …
How can this happen? Isn´t aluminum supposed not to rust? well I know it does “rust” a bit but that superficial layer of rust protects the aluminum from further rusting. What is it due to gas, coolant…??
