Valve guides loose
 

Engine is running OK. Some blue smoke, removed exhaust system to check and found #3 and #6 valve guide loose.
Is it possible to remove springs, slide out the guide, use red thread locker and install all back ??
First picture shows the guide is all the way in, second picture shows the "sliding" guide

No. It's not possible. You need to remove the engine and disassemble far enough to remove the cylinder heads. They're a interference (press) fit.

Yep - only one course here. Tear it down.
The guide will also have flogged the fitting in the head. It will need replacement ones machined down to the appropriate tolerance for the damaged seats - which will probably need to be cleaned up as well. Basically match interference fits.
If you try some temp remedy as you suggest, you will just make things worse.
Be prepared for 'while you are in there'........

Yes, will do a complete rebuild incl. Splitting the case
Thank you

There will be issues with the guide bore being worn oversize. That will require machining of the bore so it's straight and true and custom oversize guides. Might be easier to find another matching good head(s). The seats must be recut after guide replacement.

Oversize guides are common. 0.513" is std from memory and 0.516: I think is the OS.

From looking at the photos, you will be into the heads for more than just guides. As the above post correctly points out, you may have to have a custom guide made. This is not difficult as blanks are available.

Disassemble and clean the heads and go from there. Things to check are,
cracks around the guide boss, guide bore size, Valve stem wear, seat heights, any damage on the spring side.
