OK I have my modified lower plenum back now -and ready to fit - is it possible to remove the lower plenum by just de-tensioning/clamping the timing belt, removing the upper/middle idle pully - and then wiggling the lower plenum idle pully shaft out of the timing belt back cover hole carefully backwards?

 

Or do I need to strip right back, remove cam sprockets, rear belt covers etc?

 

(yes I already have the plenum off etc etc etc.) :rofl::rofl:

 

I have no EGR to get in the way so...

I guess this will give me access to the knock sensor right?

Is it worth relocating it whilst I am in there? And if so where is the best place?

bit of a dodgy one that. i personally would strip the front down. if the cam pulleys slip the belt might jump a tooth on the crank sprocket so it would be a strip down anyway. also, the tensioner might well "tension" whilst the belt is slack.

 

to be honset, i dont think it would be worth the worry but, of course. that is my own opinion. you may well find a way of securing the cam pulleys some how.

I may give it a try with the belts firmly clamped to the cam sprockets and the tensioner bolted - I will let you know....

Let us know how ya get on pal, I'm thinking of doing the same, I have the plenum off, but my dett. sensor is relocated, thinking of putting it back where it lives whilst I have access......

Will do Tudor - I shall be having a go at this the weekend (weather permitting).
