SC Oil service

[gunscrossed]

Decided I’d do a “quick” oil and filter change on the SC as the last one seems to have been Nov ‘22 (although covered hardly any miles)

Warmed her up and got under to drop the oil from the tank only to find that it looks like the drain plug is rounded off!

The filter was also almost impossible to remove. 
I’ve pumped the oil from the tank out now but wondering if I should bother to try to replace the plug, gut instinct is saying leave it in case the tank gets damaged 🤔

Looks like that tank needs to come out and get cleaned, treated and repainted.

You can drain / flush from the rubber S pipe easy enough

I have a cheap eBay oil pump that I bought for my daily so used that but wondering if I should bother with a new sump plug for next time.

As above, drop the rubber return hose and that'll get it all out if not a touch more.  Then sort it properly over winter.

 

Was it some kinda splined head?  Doesn't look like it was a hex bolt or is it just totally mullered?

You need one of these as well:

Looking at the pictures a bit more closely it looks like it might be a splined head of some sort 🤷‍♂️

You still need to get that tank out and protect it before it becomes pin holed with rust and to have to buy a new one anyway. I had exactly this issue and we all know how much a new tank is.

I’ll certainly look into it, the car never goes out in the rain and is garaged so there’s no great rush.

It does look to have been butchered.  Could you clean it up a bit so that we can see the plug a bit better.  These plugs really shouldn’t seize in place as there’s plenty of oil in the threads and an aluminium crush washer.

I had this same problem with my SC. I used an Irwin bolt extractor socket. It had a good grip on what was left of the bolt. After a few taps with a hammer, it did come off with ease. I share your pain, but the relief when it starts to turn is ecstasy.

Had a closer look at the drain plug today, looks like it’s just a standard plug but totally mullered 🤷‍♂️

[Ian Comerford]

Something like Stillsons will get this undone.  You will be throwing it away anyway so damaging the head further isn’t an issue.  I would give it a few taps with a hammer on the head of the plug to shock it loose and then use the Stillsons.

NPR, but when I was little in the early 60's, my dad who did all his own car tinkering, with me always at his side, decided to change the oil of the Austin Cambridge he had recently bought. The drain plug was not unlike the one above and with the limited tools he had available he couldn't shift it for love nor money. So he went up the road to see Terry who was a bit of a "mechanic" to see if he could help. He came down with his tool box (very comprehensive compared to my dads ) but couldn't move it either. But, he was a bright spark. He went back up the road to his shed, detached his vice from his workbench came back, tightened it on the nut and hey presto loosened it in a thrice.  Think it cost my dad a packet of fags. There's always a way.....

As 1982SC said earlier, I’d get a bolt extractor socket on it

Or pipe grips on the larger outer part.
