Since xman casually threw "turbo actuators" into his reply to my earlier spark plugs thread I of course had to go and investigate!

 

Seems I have got a shim behind mine (which I'm assuming is a good thing as it's a fix for a known problem) but it also prompts me to mention that I'm missing a screw/bolt with a hole in the turbo cover but nothing obvious below it for it to go into!

 

What am I missing?

 

 

Nice and clean!! 

 

Googling images of Cbzb engines show some with one screw, other with two. Different turbochargers have been fitted during production.

 

I'd hazard a guess the turbo has been off or even changed and a new gasket seal fitted, one that had only one fitting for the heat shield

I see the leads are nice and new NGK, not OE leads (also made by NGK but not marked as such which also had some thick sleeving in parts going over the stainless pipes..

 

Regarding top timing chain cover, the one you may have seen with a built in chain guard was an ineffective stop gap measure and not the final solution. The upgrade kit doesnt have or need that as the chain skips on the bottom sprocket rather than the top.

 

The upgrade kit has a wider chain with a different link configuration, new sprockets revised guides and redesigned tensioner.

 

This is the new kit, all parts need to be replaced on engines built before Oct 2011

Here are pics of the old set, you can see the old top sprocket has the part no 03F 109 571C the new sprocket part no is 03F 109 571F

 

Lots of info and pics showing the differences between original kit A and new kit B here

Are these engines prone to being dirty?

 

Yes it is the cover with the guard I was thinking of, unfortunately I can't seem to find a part number on it nor for that matter, despite the attached image, have I yet to find the engine number!

 

Given that it's a nothing job I think I'll schedule in a peek under the chain cover then I'll know for sure what I've got.
