Well I guess I can only learn from my mistakes I checked my oil in my 2007 on the weekend and I notice I was quite low,so I found my oil read the weight 30w 75 transmission oil, so I added a litre, then when I replaced the cap,I noticed it said 10w 40. So palm to the head I had added the wrong.
In my defence the bottle said "suitable for motorcycle transmissions" and the I thought "oh yeah the transmission of a motorcycle is in the engine so this must be the right oil"
Luckily I did not turn the engine over so hopefully I have not done too much damage.
Anyway I pulled the sump plug tonight and this spring came out of the sump? the spring has sharp edges and is quite brittle if broke a couple of times as I was handling it, it feels like aluminium and it has the same thread as thee sump plug.
Has anyone else seen something like this? Did the last person who changed the oil just strip the thread carved out this spring? or did I just pull out a vital part of this engine?
The transmission oil won't hurt anything, especially if you changed it with ordinary motor oil before running it. It just has friction modifiers and a different weight rating scale than motor oil, different additives, etc. But it's not like it's going to make it blow up. It'll be fine.
IDK about your sump plug.
Oh, someone may have replaced the drain bolt with one of em fancy quick release things ... Put a picture up.
The correct part is a simple bolt, 14mmX1.25 I think.
However, you may have had a case of chewed up threads in it, and the rubber drain bolt may have been their way of "Fixing it".
Cool.
Buddha.
You are gonna have to re-tap a bigger thread or helicoil it. Thge Al spring was the case threads coming out...

That was my first thought. Probably easier and more reliable to re-tap. Probably a lot cheaper to helicoil if you don't already have the right tap, and almost nobody other than a machine shop has metric taps that big.
Sucks :(
There are other solutions but they are all worse in terms of cost and work required.
You have to remove and refit the sump, and change the gasket regardless.......easiest way out is to find and fit a 2ndhand sump. Ebay is the best bet, unless you have a decent breakers local
Sledge has a good point. Should be able to find a second hand one. even here if someone has a motor or two pulled down for parts. It's not a common damaged part so there should be a few. Give you a chance to clean the bottom at the same time.
