Oil pressure sensor install - where are the oil ports in the cylinderheads ?

[sparky]

I have the oil feed adaptor from SoS that provides an 1/8" NPT port for my new AEM Oil Pressure Sensor (30-2131-100).

The factory drill plug provides the oil port on the rear cylinder head (see the SoS picture) but this would put the sensor too close to my Top Speed headers, so I went looking in the front. My question: where on front cylinder head should I look - on the corner near the coolant reservoir, or the other corner, near the timing belt covers?

AFAIK there are only four ports in total:
1) two drill plug ports ports, one on the front and one on the rear cylinder heads.
2) the feed port on the left side of the engine for the factory oil pressure sensor (that I want to leave as is) and
3) the feed port for the oil pressure switch near the oil filter.

Are there any other options?

Ill verify when i'm under the car next but from this picture it looks like its on the trans side, which make sense:

There also looks to be a little more clearance too. Im not using my front port either for the same reason except I have the Comptech headers. Just a warning, Getting to the front head where the port is is a bitch, you'll need to take off the front lower rear beam I had to do this very thing last week to swap 02's, I looked for every short cut I could find but had to bite the bullet and just take it all apart to get clearance for the breaker bar.

Pro tip: Its not immediatly obvious but Honda did us a solid and put a tabbed nut on the motor mount bolt nut. I only saw it after i struggled to for 20 min trying to figure out how I was gunna get a socket or wrench on the other side.

I dont think there is another factory port other than the ones you listed. If you do use the front port I would suggest either wrapping your sensor in heat blankets or fabbing up a shield some how. Those sensors tend to go out rather quickly when that close to heat with as little airflow as the front bank gets.

good info thanks illwillem. Yes I've done work in this area before - a pain in the a***

"tabbed nut" - does that mean I have to release a smaller nut on the tab before undoing the main nut, or perhaps it is a tab I have to fold away from the main nut?

It means you dont have to hold nut 16 while unscrewing bolt 13

Cool ... I'll have a closer look ...
