Got my cams through post ( thanks Steve ) but I just want to know the lift/duration of the inlet cam so I know if i need valve clearancing as RB said they can't tell what cam it is but it isn't standard





It also says N401-001 on the back of the cam

Duration does not effect clearance. They are 9.1mm lift.

 

[DazGTR]

How did you work that out I'm curious

 

[DazGTR]

Question is do I need to reshim the head as it's just been done about 1500 miles ago

 

[Nexen]

you will need to check clearance as you dont want them to tight .

 

[DazGTR]

Do I have to remove the head

 

[Nexen]

No Daz . need to remove cambelt and swap cams over and check clearances with feeler gauge before put back together . Its more time consuming than it sounds but if all clearances are fine it can be done in a day

 

[Nexen]

easiest way to check is get a micrometer not a vernier and remove the 2 camshaft covers and measure lobe and compare to the new one . dont need to measre lift , just smaller diameter like you have in the first pic but where the valve wont be in lift

 

[DazGTR]

So when you next free ash ? Lol

 

[DazGTR]

What exactly am I checking with feeler gauge

 

[DazGTR]

What size is the oe base circle ?

 

[R32 Combat]

You will need to check and probably re-shim the head with every cam swap.

 

[DazGTR]

Bummer it's only been done recently

 

[DazGTR]

Just a question how do I reshim if for instance it's too tight ?

 

[DazGTR]

Sorted it sent head off to be shimmed and valve clearance checked
