Spring loaded Exhaust VVT Full rotation range?

Post by volvolugnut »

I am a bit confused on the normal rotation of the exhaust VVT on 2001 V70 T5. This has the spring loaded VVT on the exhaust shaft only.
I am replacing front side cam shaft seals and have a question about the range of rotation on the VVT. I can smoothly rotate the VVT hub in the CW direction against the spring. Should there be any rotation CCW from the spring relief (no tension) position? I have no CCW rotation on my hub, but some notes seem to imply the hub should have CCW rotation from no tension position.

Pretty sure the answer is "no" but without the hub in front of me I'm not fully confident answering timing questions. :)

This video tells you almost everything you need to know and I think answers your specific question:
'95 854 T-5R, Motronic 4.4, 185k
'98 V70, T5 tune-injectors-turbo, LPT engine, 304k, daily driver
'06 S60 R, 197k
'07 XC70, black, 205k
'07 XC70, willow green, 212k
'99 Camry V6 :shock: 153k
gone: '96 NA 850 210k, '98 NA V70 182k, '98 S70 NA 225k, '96 855 NA 169k
