filter is clean.
new guide kit, shimmed up new tensioner (3x1mm washers), brand new chain -- still got the noise. The new chain was about 1cm shorter than the old, and the old guides were pretty worn. i thought it was going to be perfect, but alas... i am running jmm springs, i think i will try crow doubles perhaps. running out of options. hope it hasnt snapped the passenger side guide already, f**k if i have to go through that for a 4th time.

JMM is f**k rubbish. I THINK they have a high lift short duration cam that causes harsh backlash.... f**k it off get and get a real cam...

I think its spring related. Im not using a JMM cam - I have a Wade 1521a - but im using JMM springs. The cam has 0.524' lift at the valve.
The specs of the springs I know of are: CROW 7739 - 90lb CROW 7738 - 110lb CROW 7333 - 125lb (doubles) Does anyone know how many pound the JMM springs are and what a minimum would be for a cam with that much lift? What are others with cams of similar lift running?

http://www.camtechcams.com.au/cat/forde6.html Ive ordered the CT830. carefull.... with a lower revving, relatively low comp engine you dont want too much duration. Mal and they boys @ Camtech are great, and dont get me wrong, they do have good grinds, but for a std rev range <10:1 comp 6cylinder, I wouldnt go much over 225* @ 0.050, & make up the rest of your AUC window with lift. Just my 2c

Just my 2c My motor is fully rebuilt with 10:1 compression, and a 360HP flowing head.... The engine shop convinced me that was the cam of choice for my setup and engine. I will revving my engine to 6200.
