Quite telling your use of the phrase "weekend job". By comparison I did an engine swap on my 68 Cortina on my own in the rain, though the rain likely speeded up my work! Granted the Cortina was a very basic car and incredibly easy to work on. I needed a whole weekend to lift or replace the engine in my metro as it was a lot more tricky, though my mini-racing pal could doubtless do it in a couple of hours

I don't rush my jobs, not a mechanic by trade. Kudos for doing engine swaps on the side of the road :okay:

I think "dog slow" might be a bit harsh given it likley had the same power as my Cortina back then !

Quoted at 48hp but that was a crankshaft reading, by the time it had gone through the transmission and shaft drive it was somewhat less which was why they tried bolting on a turbo and then boring it out to 650cc (actually 672cc)

/Hi all,

I/'m patching a seal on a 944, not a big hole it needs doing but it dose not need a whole new seal yet lolol it first welding and its a 1984 not bad. i think it was caused by someone trying to lift it in the wrong place.

now my question is 20 gauge 0.9mm steel or little thicker? just want to make a nice job of it :smile: ?

Still about 230hp per tonne.
My Cortina had a claimed 60hp

20 is ok if you've something to weld to...or if that's all you've got.Id be tempted tor something a little thicker...16 and you won't blow holes in it !

Isn't it best to use same thickness steel where possible

I find it difficult to master. I practice alot on similar thickness until I get a presentable weld and not blow through the metal.

Half the battle is getting the settings right but without the experience I found it far from obvious whether I needed to twiddle the feed or the heat. Neither It was it always obvious to me whether I needed more or less, though blowing holes suggest too much heat, or perhaps not enough wire?

As in if you're an amateur welder... especially with mig the thicker the metal the less chance you have of blowing holes in it,keep the heat on the thicker metal as much as you can.
Always preferred gas welding oxy/acet myself,far more control over it for me on car bodywork,all depends where you're welding I guess bodywork or structural.But as with most things it's more about preparation and taking your time.My boss at the time had an old MGB that I had the luxury of welding up....bet it's still around as I'd welded stainless steel sills on it 🤣
Served my time as a sheetmetal worker/welder but never used mig back in those days.Got back into welding in the last few years...more hobby work and some art projects for my partner.Bought a mig welder but hate it...I can use it but rarely by choice.
