Valve guides - Spex - 20-01-2020
I am getting valve inserts fitted with new valve guides.
The block is 54xxx. I got flanged guides, but the valve man says they are not correct.
Is it a case of "I am always wrong"?
I have not seen the problem but will do so in a couple of hours. (Its daytime here)
Are the two types interchangeable?
Thanks in advance.
Cheers, Peter

hi peter,
there are two guides available for the 7. as they went from one type to the other.
so should your block actually be stepped guides. or should it be parrallel.
they are both different thicknesses.
also be careful.
last year there was some stepped guides on the market, that were made to small, the manufacturer took them of the market as quick as possible. WELL DONE.
but you may have a set that didnt get returned.

If your block is 54 something then they will be stepped guides.You will also have screw in core plugs on an earlier block although I have seen screw in core plugs with straight guides.
Easiest way to tell is to knock one out with a drift .

Embarassment, I will go and hide.
Block has straight guides.
On very close examination of the number, there was a "1" in front. So 159xxx
The face had been machined for some reason and it was hard to make out.
Thanks for both replies. Now to get the correct guides.
Cheers, Peter
