Has anyone had there inlet valves walnut blasted to remove the carbon build up that these turbo direct injection motors can suffer with ?
Symptoms can be a slight lumpy cold start as the extra fuel that is dumped in doesn't atomize properly.
It's quiet an involved process.
Wondered if anyone has had it done apart from a better cold start could you feel any other improvements ?
 
Got mine done here a few weeks ago:

The engine feels smoother, but i don’t think it’s done anything to the performance.

Such a relief to realise this thread is to do with engines. :lol:

It is now yes....Our Nige had to think fast on his feet and change the meaning once he realised he’d initially posted his question on completely the wrong forum......naughty boy..... :P
 
when I was researching walnut blasting there wasn't that much info on it. imagine how many poor sods are gonna get excited about this topic coming up in a search only to realise it doesn't really provide much info on the actual subject.
 
I think Firebobby Fred had a meltdown from fear at the term 'Walnut blasting'.
Fear at the thought of his prized walnut veneer in the zed being obliterated!
:lol: :rofl:
