[Rb25 head stud thread height]

Hey guys, 

 

I am re-assembling my head and I noticed when removing the arp head studs, a couple of the nuts had bottomed out on the thread. i was wondering if anyone knew the height required for the threads to not bottom out. 
 

From my measurements;

-Block face to nut 70mm (both wound in

all the way by hand) 

-Washer 3mm

-Factory head gasket 1mm

so this means if the height of the cylinder head face to the washer face Is less than 66mm the nut is not actually compressing the head down. Factoring in machining of the head I know there will be differences but does anyone know the factory height of the head? If it’s something much lower like 65 then I know it was just the stud not wound in properly but just want to make sure I’m getting proper torque as I have read some people double up on the washers 

 

 

[C34 injector relay location]

Hey guys, 

Just a quick one I can’t find any info on. Im installing a haltech elite 2000 into my c34 stagea. It requires a signal wire from the power output on the injector relay. I’ve tried the engine bay, under the drivers kick panel and drives coin tray but have had no luck finding the relay I need. If anyone knows of the injector relay location please let me know

[Floor pan under carpet covered in oil]

Hey guys, 

I was about to run some fuel pump wiring and came across this. There is oil covering the entire floor under the carpet and it goes all the way to the back seats. Strange part is the firewall is completely dry, it is only on the floor pan. It’s as if someone has deliberately covered the floor with oil, has anyone seen something like this before?
