Thanks Valdas, great work and a really quick turnaround which was of great help.

Car had been serviced from day one at a main dealer, but the plugs were obviously never changed and
they didn't spot at the last major service a couple of thousand km's ago that the timing chain needed
attention, which is all worrying imo

Seen Valdas in action today doing a chain, amazing attention to detail, cleaning everything as he went and making sure everything else was in its place and working just right. GREAT work

Hi all, sorry to bump an old thread. My valve cover gasket is leaking and needs replacement. Is it necessary to remove the injectors for this repair? On the pictures above, I see they are missing. I heard they will need new o-rings after removal. Thank you!
