knocking engine

Post by **gally** » 19 Jul 2008, 20:22

wondering can anyone help me
if me van is left for a few days when i start it up.
the engine shakes baddly spluttering and farting with a knocking sound,
the rev counter jumps between 600 down to 2/300 rpm ,
if i give it throttle it dies altogether.
then after a couple of mins its fine purring like a cat.
going to france in a couple of weeks and a bit worried
cheers

It's probably just the hydraulic tappets re-filling. Make sure you have good oil and a proper filter fitted before you go to France. Man, Knecht, etc filter 070115561

Make sure the wires going to the bolt on the left hand head are all clean and earthing properly too

i have been using castrol valve master lead replacment cas i havent got a chance to get someone to change the timing yet.
could this have something to do with it ?

I prefer a 20/50 oil... is it a loud Tapping.. that stops after a short drive?

The fuel to use is super unleaded for a 2.1

normal unleaded is the wrong octane rating ... unless you re-time it as you say to 5deg BTDC

you don't need lead replacement additives in a 2.1DJ VW engine

the whole engine shakes and it like struggles to stay running.
