The final exhaust valve from VW heritage finally arrive last week after about 4 weeks waiting so i fitted the valves to one head and then took the other head apart.Upon fitting the new valves i noticed there was loads of play in them.

With some help of an expert!

i decided to tackle replaceing the guides myself, i had been told this is impossible etc etc you need 100degree heat -1000degree nitrogen etc etc
First i tapped the guides with an M10 thread

DIY extractor

Extractor in use!

MAGIC its out

The removed extractor
Next i have to fit the guides. Couldn't find valve guides from the usual suppliers but Coolair VW had them in stock next day delivery free over £50 arrived quickly great service will be using them again for sure.
I am in the process of having the drifts to fit the guides back in made, I have also bought a compressor and some air tools!
My only question is the exhaust valve guides have a area that is a few mm bigger on one side i think this goes on the valve side a posed to the rocker side, is this correct? can take a pic if needed.
Anyway thats my marathon posts for now.
I will hope to keep this abit more up to date.
