So i had to take off the manifold to repair my power steering pipe and found this!!! 50% blocked id say

Dug it out with a spoon and tent peg

There was alot more inside the manifold, my grass is black as i jet washed it out.
Resonator bushes were missing all together and this was the result Glow plug live wire!!

After Cleaning but i didnt do a deap clean

I suppose i had better clean the EGR valve as this stuff was thick and very sticky paste.
Can i have a link that shows how to remove it or how to clean the system.
