Camshaft Adjusment

Post by madi » Tue Jun 02, 2020 11:40 pm

Hi guys just thought id give the car a drive after being parked up for a few months. Upon starting i heard the rather loud tappets which die down after a minute or so. However after blipping the throttle id hear a rattle (around1200RPM). The rattle comes from the passenger side rear, so i think thats bank 2. I took the car to a few garages and they were all stumped on what it could be....

Anyway started using google and came up with some interesting threads regarding the cam chain rattle, camshaft adjustment etc so i used a neighbours lead, turned out to be a clone but did the reading just fine..

Just hoping someone could shed some light on how to interpert the data.

Any help appreciated,

Thanks

See the threads I posted here :

Long Story Short :
Block 093 is what you're interested in. Target is 0/0.
In my case, I replaced the shoes on one bank, plus the adjuster on the other, and then a new cam belt (it was due).
With a couple of goes at the cambelt, ended up with it back to exactly 0/0 (mine started as -1/-8)
