Hi all,
First post here, wondering if anyone could help me confirm what size/part number o-ring I need for a mk5 Golf 2.0Tdi pd140 BKD engine code. It's the o-ring sealing the boost pipe to ASV/inlet manifold coming from the intercooler outlet. I can attempt to link a picture if needs be.
So far I have been pointed towards part number 3c0 145 117f which is a 57.85mm diameter o-ring and 1j0 145 769g horse shoe clip if that is not as tightly fitting as it should be also. I want to confirm before ordering as there is also a larger 61.9mm o-ring with part number 3c0 145 117h
Is it best to look for a green viton or similar oil/fuel resistant rubber which should last longer with slight oil blow by?
Are there any mods such as heat shrink/self immalg over this connection that anyone has done as it's the only weakpoint left as the rest is now hardpipe, silicon hoses and power clamps.
Thanks in advance!
