[rollover]

I am having trouble sourcing exhaust valve guides in .au for the standard motor
while the inlet guides from a ferguson te20 are the same, it appears that the exhaust guides are 30thou bigger in the OD
any help would be appreaciated

I had the same problem with a citroen car engine about 15 years ago. Machined up a new set from some blanks supplied by the local engine shop.

They also bush worn guides by reaming them out and pressing in a thin walled bronze bush. I had that done on a honda engine and had no problems with it in the following years.
