Anyone know what to use to plug up the oil return and the oil line on the side where the exhaust is with, because im starting a new project with an rb25det in a 280z and need a daily driver. I'm taking the greddy kit off.

 

The OEM plugs work pretty well.

 

The truth.

 

whats the part name for them?

 

ok found the part number for the one by the alternator whats the one be the exhaust manifold called please?

 

Alternately, you could just use a short m10x1.5 bolt and a copper washer to plug the block on the exhaust side. That's all the stock piece was.

 

Get an adapter and run a sweet oil pressure gauge.
