Hi


I've got some rust im a little concerned about in the engine bay... to be honest i havent seen too much of it other than battery trays

has anyone done repairs here as bad as this?



Some how use this piece to fix the above







That is as big as the hole gets.... firewall rust is concerning

[Edk]

Anyone got any pics of engine bay rust?

[Heath]

Shit that is pretty worrying. Some of the stuff on the blue car around that area is a bit average as well. Will try and get some pics...

[Edk]

Yeah judging by these pics alone it would look like that....


i dont understand how a engine bay would get so rusty like that... bonnet must be leaking or something

I didnt think it was common

[Edk]

I repaired some rust on the same model early this year....even had rust behind the passenger bonnet hinge.

More than likely it's been residing around a damp or seaside area and out doors most of it's life

Yeah it came from around Bittern up near phillip island somewhere, amazing it didnt have more rust.. the car is so original, and i recently discovered it has a uncut dash

What about safety with welding in the engine bay? can it be done with the engine in?

[Edk]

So 15 years later lol, i've cut out the rust and replaced it best I can... still working on it though.

 

Sorry not good at welding... and not easy to get good welds with gasless mig.

 

Also replaced the lower rad support and almost finished the rear tail light.

Good work, and good to see you still have the old girl.

Do yourself a huge favour and ditch the gasless setup and go for gas.

Over the years quite a few people here have started with gasless, myself included, and everyone ditched it for gas.

The only time I have found gasless any good, is with stuff over 3mm thick, or when I was helping a mate hardface excavator buckets. And that was with 1.5mm wire and a 400 amp machine.

 

Your welding will be much better and easier with gas.

0.6mm wire, and a bottle from either Bunnings or a Tool shop that you dont pay rent on is the go.

Gasless is good for working outside in the wind. That is about it……

Amazing what can be done with strategically placed tarps.

When upgrading to MIG with gas, is it Argon/CO2/O2 that is the go? I thought the gas was supposed to protect the weld from oxidation yet O2 is actually in the “MIG gas” mix?

[Shiney005]

I've always used Argoshield. I believe the argon helps maintain the arc when welding thin materials on low voltage settings. Argoshield is a mix of argon and CO2.

[Rockoz]

Most places have MIG gas in a mixture that works really well for MIG.

Dont worry about getting into the whys of what is in the mix.

I have 2 gases at home. One for steel MIG, and another for TIG and aluminium MIG.

I have done steel and aluminium MIG work with the same gas over the years.

It still works, but it works a bit better with the right gas.

The type of welding you will be doing, the gas choice wont be super critical, as you wont be needing your welds to be xrayed.

yeah my welder doesnt do gas as well. I might upgrade one day... i find if the metal isnt old metal i get pretty good welds, like welding in the new battery tray.

In the scheme of things of doing car rust work, the price of a decent MIG will end up saving you money in the long term.

You will save in terms of time spent, as well as requiring less consumables to dress up the welds you do.

Have a look at a Unimig welder. They are relatively cheap and they are good for the job.

 

There are a few people who have posted here over the years that started with gasless then bit the bullet and got gas.

Pretty sure every one of the basically went and redid their welds when they saw the difference in quality.

I know I did.

I was trying to do a project on a budget. Ended up costing me more than it should have.

 

Usually the gasless machines are pretty low quality and they will break down. Then you will find it difficult or impossible to get replacement parts.

Yeah I don't doubt you Rob.

Here's some more pics...
