Hi,

 

Book says 1989 998cc Mini City e but after some advice on here that might not be strictly true and it has a seventies 1098cc engine.

 

The old sump plug came out OK. 

 

When I try and put the new one in with just my fingers it only goes in half a turn.

 

Do I just apply some force or have I got the wrong one?

 

Please let me know what you think.

all Mini sump plugs are the same.

 

I would be checking that they both have the same thread and then I would be inspecting the thread in the sump.

That new one doesn't happen to be a Minispares gold sump plug does it? I found my one to be an extremely tight fit and I had to carefully wind forward and backwards to get it in.

Out of interest what is the reason for changing the plug?

[Hugh Jass]

I got the new one from mini spares. I just thought it was normal to replace as they are quite soft metal?

The copper washers are replaced, sump plugs should last forever and are much tougher than the gearbox.

to check if the threads are the same put the heads opposite each other and line the threads up and push them together and they should match perfect if they don't not the same thread...

 

best pic I could find , as in pic and hold them up to the light to see if they match....

 

or your sump plug could be starting to strip if the threads match......

It's quite common for the threads in the Sump to distort making it impossible to screw the plug in with the fingers but needing light gentle spanner assistance.

quite hard to do with the magnet stopping the threads coming into contact with each other.

The sump plug is critical to torque only to 25Nm - most people over tighten it with the long term potential of stripping the coarse thread. Quick lube shops have a history of stripping oil sump plugs

 

And yes renew the copper washer at each oil change or anneal it.

Referring to what Trissy B said. I bought a minispares gold gold sump plug a few months back as I was told they have a stronger magnet so I gathered it would pull more debris.
Upon fitting mine I thought it was rather tight. I tightened it gently being careful as it felt like it was cross threading even though it wasn't. I've checked since and it's not leaked.
It was good to read someone else thought the same, just out of curiosity why are the gold plugs so tight?
