Punched a hole in my oil pan! (1.8t AGU Golf)

[Fatty]

Hi all!
a bit of mild drama for you!
I was driving with my friend on some gravel roads, playing with some flicks and so on, I hope you understand. unfortunately i missed a rock which made quite a bang. It wasn't until I was driving back down a logging track (which is how I get to the road I was using) that I got a oil light and a 'STOP' message.
So I stopped, and checked. yes, I had in fact developed quite a leak...
Luckily I had one and a bit litres of oil in my boot which topped me up enough to get to a petrol station. where I bought 5l of some (less than satisfactory) oil.
so obviously i limped back home, topping up the oil every 10 minutes... made it home into the driveway, oil still pissing out and i didn't throw any lights luckily i think i stayed on top of it. however now I have a problem...



Im just stoked it is only as bad as it is, y'know?

[Fatty]

theres a before shot for you

I have found an Audi A4 1.8t and im fairly sure its an AGU at the wreckers!
Ill let you know how I go getting the new pan, (any other parts I should look at snapping up while i'm there?)

ok update:
I removed the sump, the hole was small, 2 cracks in an l shape, and a dent.
I hammered the damaged area flat which sealed the hole, and then welded the area from both sides. will grind flat and refit tomorrow morning!
the terrible quality weld makes it seem like a big crack and like i ****ed it but its a solid weld, will just grind flat tomorrow and ill give u an update and some stuff on putting it back i guess

Nice result. it looked small damage going by your photos and that you could top up and drive.
Take the time now to clean the oil pickup while you are there.

[Fatty]

yeah it had bits of an old oil dipstick boot that had perished in there :O!

Wouldn't grind the welds too flat. The alloy sump material is rubbish so I'd leave as much weld as possible there

[Fatty]

thanks dylan, I actually discovered this too late, the weld was just on the surface so when i got down closer to the aluminium it just lost its strenth however i didnt grind the inside weld at all, and there where no loose bits.

I just used this super tough black sealant stuff all over the outside area of the crack, it formed this tough rubbery patch. i cant remember the brand, I got it from a mate of mine.

just a quick pick of the fix. Its back on my car now, but im missing a bolt so im just gunna nip to the wreckers tomorrow and pick up a freshie before i refill the oil. Im using 5w-40 fully synthetic but In this heat would it be better to go to 5W-30?
anyway Ive replaced the oil filter and cleaned the uptake.

Ive used that gasket paste stuff to make a new gasket, Im a little nervous about how that will go but i think it will be ok, I put it on in a way which i assume wont squeeze out on the inside.
has anyone got any tips for the gasket? Ill have one ast chance to change anything tomorrow morning before i refill the oil.

after speaking to some guys on facebook I think next time if anything like this happens, I will stop and call a tow.

My next project (after a 2.5" DP) will be fabricating a skid plate...


EDIT:
I still might take the sump off the 1.8t A4 thats at the wreckers while im there? is that selfish... ?

The A4 sump doesn't fit, the motor isnt transverse so save your money.

You have the oil the wrong way round. The 5/40 would be better for the heat, staying thicker at higher temps, but still thin from cold starts.

There isnt a gasket, sump to engine. VW use sealant, just the tiniest amount though. Both surfaces are machined flat. a 2mm bead would be plenty.

yep, I found that when I got there, luckily I found another mk4 gti, so I went to dandy to have a look... its oil pan had a big gash and the engine was cactus... a sober reminder.

anyway, the weld was rubbish so i redid the repair, though this time i used an aluminium brazing rod. actually quite happy with the repair.
now im just waiting for any leaks. i'm particularly paying attention to the flange, i mean I may have used a bit much if thats all they use at VW. i put a thin even layer all the way around but not as tidy as that.
Ill be doing some careful watching and research and ill report back.

on the plus side I got a fresh set of gti floor mats for 10$ at the wrecker!
