I live on a farm in east central ohio. I currently have a 2001 Jetta TDI with 190k. I am in the process of rebuilding the turbo (with a new CHRA), decarburizing the manifold, etc. etc.
This is my fourth VW diesel. Each of the first three were 100% trouble free and each lasted over 300k miles. The first two died when the fuel pumps failed, the third (jetta) I gave to my son and it is still going strong at 375k.
I am trying to decide whether or not to pull the head while I have the manifolds off. I was thinking mainly to clean the intake ports and re-seat the valves.
I would appreciate any advice on whether or not this additional work is worth the trouble and money.
I am retired and don't have much money.
