Hi Guys,
So i think i have the dreaded broken cam chain tensioner on my hands :
Only owned the car for 2 weeks!!!
This is the first time in my life ive had two cars on the road and so thought i would have a go at doing this myself. And enjoy working on my own car for a change,
But before i begin, is there anything else i should test before??? I have kind of jumped to the conclusion that it is the chain tensioner.
the chain rattle is only during cold startup and is less than a second, i believe this is 'normal'
i noticed a lack of power, and CEL warning light under load. at low load it drives sweet,
Haven't yet plugged in VAGCOM, only used generic bluetooth one on phone, it read. random cylinder misfire code. and misfire on cylinders 5, 6, 7 and 8.
when under the bonnet, i can hear a very slight chain rattle on overrun but nothing more than this.
So is there anything else i should check before this, cam position sensor? anything else? please????
if it runs ok at idle, will a compression test show anything???
Has anyone on here had a go at doing this work DIY???
