I’m thinking maybe this stuff if it’s suitable I’ll use it on the water pump gasket and timing cover if required ?
LOCTITE SI 5980 Flange Sealant (Halfords)

How come there is 2 torque settings for the timing cover ?
I’m only doing the actual cover itself so the ones round the outside
Sorry for all questions

 

There wasn't time to apply anything to the gaskets in the factory, so gasket shouldn't really need anything on them, but if you feel that you must gorm something on them,   "Blue Hylomar"    is the Rolls Royce stuff to use.

So won’t do any harm to stick abit on them ?

"Abit", being preferable to 'a lot', and try to draw an imaginary line through all the bolt holes in the gasket and only apply it outside that line.    You don't want great globs of it being squeezed into the inside of the engine and getting plastered round the lobes of the oil pump.

Brill ?? Thank you mate

It'd be a very quiet forum if nobody asked questions. Whether your reading or writing answers it sharpens and broadens your Mini knowledge.

I'd say it's still good practice not to drop the C washer, if nowt else it may save you forgetting if you ever tackle a Pre-Verto.

Many many years ago, someone came to me for help, having "dropped" the C washer.

 

Since then I have always nipped the C washer so that it is a tight fit on the crank, in case the next person to work on the flywheel, doesn't do it correctly.

Thank you guys!
Any advice in the torque settings ?

[GraemeC]

Torque settings for what?

Back to Nick’s advice really - read Haynes. Or there is a post on here (in FAQ I think) that has most torque settings listed.

[leepol83]

Torque settings for the bolts that hold the timing cover on, Haynes states 2 torque settings for different size bolts but I’m not sure which is the outer bolt torque

The bigger ones will withstand more torque than the smaller ones.

So the 2 torque settings are for all of the outer case bolts, I did notice half of them where smaller on the way round, how will that be evenly torqued up if half are set to 10-12lbft and half are set to 4-6lbft

Just do the big ones up at 11 and the small ones at 5 and it will work OK.

 

I know that I have never torqued them up, just used my judgement as to how much I tighten them  and never had a problem with some 250 engines.

 

Look at it another way, the torque figure is given to cover the manufacturer's back, should an unskilled person heave on them as if they were the crankshaft/flywheel bolt.

[Ethel]

The blue strip is a sealant like Hylomar. It's "encapsulated" like posh wrinkle cream, it gets squeezed out when you do the bolts up.

 

 

The trick to not leaking oil is to fit the pulley before nipping up the cover bolts so the shaft can centre itself in the oil seal.

 

Also, don't over tighten 'em & gradually do up opposites - e.g. start at 12 o'clcock then 6,11,5,1,7..... or 12,4,8,1,5,9... if you prefer

[leepol83]

Brilliant ok I’ll go with that then I’m still confused about the torque settings a little it just seems strange to do one side of the cover more than the other are we sure we are on about the same thing here
The bolts that hold on the timing cover itself all the way around it on the outside where the breather is on ?

I’ve another question ? got some gaskets today from Minispares and was wondering is there a way to fit them as one side is a different colour to the other ?
I’ve got timing chain cover which is black one side red the other side
And a water pump gasket which is green one side and black the other side
Cheers guys appreciate it as always to forum ??

The correct tightening of a threaded fastener is such that there is a certain amount of stretch in it - the smaller the diameter of the fastener, the lower the torque needed to achieve the correct amount of stretch.

Hence different sized fasteners have different torque settings.
