Knock sensor .. the saga continue

[wilfredom]

Guys; I'm doing a change of knock sensor on my 2.5 .. I want to get the o-rings that seals the 2 pipes that goes in the center v .. how r that pipes called, how I'm gonna identifies them ? .. is there a kit? any problem if I get them from any o-ring retailer based on the id ?
Also need i/m gaskets .. is there something "special" that I should know about it ? ...

I guess they are called coolant pipes, someone with EPC should be able to help you find part numbers. When I replaced my sensor, I recieved an entire set of O-ring seals, for different cars, but only the bigger one for the Xedos. So I reinstalled the old, smaller one. No issues with that so far. Be sure to lubricate the seals prior to reinstall. I used silicone grease. WD40 should work too.

The IM gaskets should definitely be replaced. Torque up in steps, 25 Nm from center moving out to each end.

well x man; seems rock auto call it "coolant crossover mounting set" ..not really sure & the guy at rock either ..I ordered anyway (cheap) hoping that any of the 6 o-ring seals fit my application...
Hey bud I'm gonna start my fix with ur tutorial by my side...thanks 4 that .. by the way, u say to apply sealant to weak areas only but in the last pic, the one before torquing, looks like u sealed the whole side .. am I right? i'm tempted to seal both sides of the gaskets with a slight film of sealant & the weak areas as u described .. any opposition to this .. man is gonna be a big kick on my fat & flatulent arse if that rear valve cover comes leaking again ... thanks xedosman !!

I'm glad my guide comes handy

I'm at my cell, dunno which pic right now but its probably the end facing away from the timing side you mean? I applied sealant only to the two halfcircles and like half an inch beyond, which means like half the surface. My rear cover still seals 100% perfect; I'd say sealant all over is overkill
