Valve Spring Removal
Turbo Mini Forums

Looks like the mini has found another issue to throw at me........

The inlet valve oil seal keeps liftign off its seat, going to look at glueing it down with the spring insitue as a first attempt. After cleaning all the oil away with ear buds and rags.

If this doesn't work, have any of you removed the sring with the head and rockers still fitted.

I know i will have to make something but was wondering if anyone had done this before.

You can do it. You put compressed air down your plug hole and make some kind of lever setup from the rocker post/head stud to compress the spring. Not sure its worth fannying about with if you dont have the kit already tho.

Head off time mate

Nothing is impossible it just costs more and takes longer.

I will not be defeated, that head is not coming off just yet.

I'll end up with shares in BK450 head gaskets, you must have a few shares now Si.

Do you have inner spring locators?

If something is worth doing, it's worth doing half of.

Not sure, its a Benross head.

Its always the same valve too.

Ask Steve about it. If it hasn't it may be worth adding them and glueing the seal down as well.

Just glued one of mine in situ. Easier though, as I am only running single springs.

You can do the spring in situ by feeding soft rope through the spark plug hole then winding the piston to TDC which will hold the valve up.

How would you compress the valve spring using this method mate?

now thats a great idea, just need to make a a method of ompressiong the spring.

You'd need something that hooks under the rocker shaft with a long lever to allow you to pull the spring down.

Something like this

Headgasket is cheaper...

Going to try and fix it in situe first.

Other than that its head off, just need some more arp lube again.

Do em with oil if you have run out. I'll have a look if I still have a packet as I use a large tube usually.

may still have some on the lid i used originally as dont tend to throw things out.

I have a special tool like the once suggested, grips around bottomcoil of spring and then leavers down on cap, the good length of about 4mm Diameter nylon cord in the bore when piston about 3/4 of way up and then turn engine over by hand to crush it into the chamber to hold valve in place, this works better than the compressed air tool, I have one of those as well. Used to do this all the time on the old Sierra CVH engines.

Yup, rope method is a doddle, and more trustworthy than air.

Although if you used air and the piston at TDC, even if the air seal is broken, the valve wont fall too far.
