Hi guys, I need some help from more experienced guys.
Below is a picture of my head that i removed from my car because of bent valves. when i removed the injectors i noticed some wear on the head where the o-ring on the injector is (marked in red)...has anyone had issues with this???
Side note, i have bought a new cylinder head because i dont want issues later on.

Re: Wear on 1.9tdi cylinder head
From what i know, that sort of wear is caused by a loose injector. How deep is the ridge?

Re: Wear on 1.9tdi cylinder head
The wear on number 2, injector in the pic is the worst. its hard to gauge the depth but i would guess around 0.5 - 1.0mm

Re: Wear on 1.9tdi cylinder head
In my opinion, that would cause an issue. Possibility of the seals not sealing because of the wear, or the seals getting damaged when fitting the injector in.
I personally wouldnt want to use that head. However, U probably might get away with trying to lightly sand down the burrs and maybe use slightly little thicker o-rings, but i wouldnt encourage that, its a chance.. if im not mistaken theres a few guys on the tdiforums who have dealt with this problem - i cant remember the outcome though.
I also noticed a wear mark below the 1 that u have outlined.
Was the injector nozzle damaged by the valves?

Re: Wear on 1.9tdi cylinder head
Ill take a look at the tdi forum to see what they did. Nothing else was damage by the valves besides the valves themselves, however I bought a new head and replaced everything besides injectors and and cam...thought i would try and fix the old head incase someone is in a jam and needs it.

If i were u, i would sell the head as is so the responsibility of repairing that is their own (inform them ofcourse)
