405 1.9 turbo diesel starting problem

What will cause a diesel to start with no problem when cold, but has a
problem starting when the engine has warmed up,the glow plug were
changed 10 months ago. can anyone help regards Simon

 

Sounds like valve clearances, low compression or a timing issue with the
fuel pump.

Has it got a hand primer on the fuel line- like my old Citroen 1.9td?
If so, try squeezing it a few squirts before trying the starter. If it
starts up ok, you have an air leak on the induction side.
Maybe only leaks when it gets hot.
Another thought, my Citroen needed a time on the glow plugs every start up,
hot or cold.

very possibly low compression, i would suggest the piston rings are wearing,
not uncommon with these engines.
