Scotty, you are a star. It staggering the amount of info that you contribute to this site. Thank you so much. May be damaged as was knocking from about May till i got it serviced in July. Roughly 5000k's I'll try to find someone with a Consult 3 unit, after an oil change. Will let you know if this has worked. Thanks again. Simon.

Hi Scotty, Thanks for the reply. Have checked the last service sheet, oil used is 10w40 semi synthetic. Is a relearn something my mech can do with his diagnostic comp or is it specialised? $500 was just for parts, reckons entire replace with labour could be over $1100. Worth a shot with the oil first. Would this be the reason my screen on the Navi system has said PIT since getting the car in February???

Hi All, Sounds like I have the same problem on my 2004 RX250 Stagea, Its got the VQ25DD and has 197000 on the clock. Mechanic has looked at the car and unplugged the left hand sensor, fixed the noise but car has the engine light on now and is running sluggish. Does anyone know of a sure fire way to check if it is spring or just the sensor playing havoc with the valve timing? My mechanic here in NZ has said the parts alone for the spring job are over $500. Would like to have it confirmed that is the problem before parting with that kind of cash. Thanks. Simon.
