Hi all
Does anyone here have for sale or have dimensions for an m20 valve guide removal / replacement tool / drift

I had thought I had these - but they are on the missing list

Any other specialist engine tools for M series are of interest to me to purchase

Am trying to get to a self sufficient position here in Ireland

At shepton & ardingly weekend after next

Hello John, if you have access too a lathe it is very easy too make.
about 25cm long steel rod with an outside diameter just below the outside diameter of the guide.
turn one end down to the inside diameter of the guide over a length of about 5 / 6 cm.
Perhaps both in and outlet guide have the same dimensions so you can use one drift for both, but do check that first.
I advise to punch out the guides after heating the part up to 250+ C .
On an electric cooking plate and -if available- covered by a piece of ceramic blanket it works o.k.

With an Iron casting, guides, seats and liners are removed and refitted at room temperature.

Also best to undercut the diameter that fits inside the guide directly adjacent to the step up to the larger diameter (at the shoulder)..Leave a radius there and you are far more likely to break the guide when drifting out...I find a 'deadblow' hammer good for the job as well...Ian
