Another halt on my mission to complete my first motor replacement or swap. I was ready to get the wire harness and intake manifold together on the motor and sure enough usin excessive force to get the harness on its bracket i incidentally broke these...



The bottom one I'm sure is the oil pressure switch in which i have a spare on the old from the old motor..

Can someone clarify what the top on is and can u let me know if it's possible to replace?

Also have these questions.
Questions:

1. What is this oil pressure switch's size. I've ran out of Socket sizes dealing with this thing in which i broke and i got up to a 22mm and it didn't even fit. I understand this is a British standard size..so how do i go about Removing this in order to place the replacement one on?

2. What is the one i broke on top? and can i replace is? also what's the socket size for that one?

What engine is this?

I think the top sensor is the knock sensor.

The upper sensor is the knock sensor. They're very expensive new; you'll probably want to try to find a used one. Be careful - as you've seen, they're fragile.

The oil pressure switch is 24mm (or 15/16"). You'll need a deep well socket to install the new one. Do not overtorque it! The threaded portion has a small diameter and will break off easily inside the block.

My apologeeze, it's a d16y8.

Targa250r, Any idea of what the torque spec is on the Knock and the pressure switch?

Not sure about the knock haven't had to change it as my ecu doesn't look for it. But i have changed my oil pressure sender and all i did was hondabond the threads and tighten it till i couldn't anymore no problems what so ever.

SIRIUS VTEC

is it mandatory to put some kind of sealant on those threads or is it just a precaution? why is it that ur ecu doesn't check for it?

On the sender is it, for the knock it isn't.
I use a OBD1 P28 with a H22 map since P28's don't look for knock.
