irractic idle after timing chain and belt change
GTI-MATT:
Just a quick update timing was all bang on. 2 out of 3 o rings where split where the oil feed goes into the camshaft adjuster. Didn even realise they where in there when i 1st done the job learnt now tho :happy2: thanks for the info tho guys :congrats:
GTI-MATT:
These ones where perished i put a little screwdriver under them to get them off and they fell to bits. Only a couple of quid like someone else said change them evertime you take the cover off. If i knew they where there i would of :happy2:

Yeah. They are oil seals.
Dan_FR:
The N205 works by directing oil through different channels/holes/routes (whatever you want to call them). The O rings maintain an oil-tight seal between each one so that you only get the oil pressure in the correct channel resulting in the correct camshaft adjustment
This PDF explains it pretty well if you ignore the exhaust side of things: www.volkspage.net/technik/ssp/ssp/SSP_246.pdf
Pesky jones:
Oh ok cheers Dan! So I guess if your adjustment is correct then your seals are in tact! Will take a read of that PDF at lunch :happy2:
