Oil Port under CAS (Cylinder Head)
Hi,
The prior owner of my car used the Oil port below the CAS on the BP head to install an after market fuel pressure guage. It looks like a 10mm x ? thread (Can anyone confirm this). I'm preping for my MegaSquirt install and it would fit due to the size of the sender, but this had got me thinking.
Why are we not using this port as an oil feed? Does this port lack the pressure to supply our turbos? I noticed it always has pressure on the gauge
Does anyone have an old head kicking around with this plug in it? I don't have the plug and need to block the hole.
Or... Does anyone know the thread of this hole so I can purchase a plug. (I'm guessing 10mm x 1mm)
Let me know your thoughts.

Oil Presure is always above 20psi at idle, and much higher with RPM according to my Blitz gauges. I'm really surprised this port is not used. There has to be a reason. I wonder if Corky will see this and chime in.

i wouldnt feel too good taking oil feed from the head
IMO it just looks like it will take a long time for the oil to reach the turbo especially if the passages are somewhat contaminated and flow is even more reduced
i do wonder if anyone has tried this or is willing to...
Sam, not sure on mazdaspeed, but my 94 block has a plug in the block on the hotside meant for oil feed

on the 99-00 head? you mean on the back?
or under the actual electronic sensor on the intake cam?
The factory gets oil press down under the intake manifold next to the filter. I teed my turbo's oil feed AND oil pressure sender in there with a BSP to NPT adapter and AN- tee.

That is how the BeGI kit i am installing does it. That being said though this is an interesting idea. It would make the oil feed to the turbo much, much shorter. This could work as long as there is room to get a 90 deg fitting in between the head and the firewall, which I think there is since the CAS is big and fits in there; I added a CAS to my '99 for the MS install.
