Bill called TPS for a price of a new VVT unit... turns out they retail for around 430 quid and the discount was rubbish!...
So... I took a chance on one from GSF... half the price and a 'pattern part' but comes with a 12 month warranty so f*ck it... worth a punt...
No markings so clearly not trying to obviously copy an OEM one unlike the chinese copies and the blatant OEM copy I bought... just to remind you the chinese copy gave me a set point not reached fault code all the time and the forgery was bought believing it to be genuine... which it wasn't...
Only need to undo the inlet cam to remove the tensioner unit... fitted the tensioner tool first then sequentially undid the cam caps to let the cam lift up uniformly...
...then lift the inlet twisting as you go to allow the tensioner and cam to be lifted out...
Slide the tensioner out from chain trying to keep the chain in its original position to keep the cam to cam timing right (can be sorted later if you **** it up of course)... I removed the inlet as it was just easier for me but as long as you keep the chain set as it was there is no need to...
Fitted a new gasket...
...and fitted the new unit... marked up the 16 rollers and timed up the cams...
...removed the tensioner tool and chucked everything back together...
...phew!... started the engine and apart from the initial rattle as the tensioner filled with oil its was all quiet and good.. yay!... checked for fault codes and nothing came up...
Hopefully thats the end of my VVT woes and potentially a reasonable supplier of replacement VVT units where you don't end up walking like John Wayne for 6 months after buying one...
No dyno today but will be on at some point this weekend...
