Hi,

I'm planning on using an oil temperature gauge on the 1997 EJ25 DOHC engine that I'm swapping into a Vanagon (thanks to Nipper for the advice). I found a couple threads about placement of the sender for an oil temp gauge, and it seemed to be that the preferred spot was to drill and tap threads for it into the oil pan drain plug. Are there any other methods that people have used successfully? I had thought that one of the other service holes on the top of the block would work, but I guess it's not a good spot?

Eh?

 

Most EJ blocks have a blocked out - hex head bolt - in the top of the block as you say. Standing in front of the car, just below and left of the intake plenum.

 

I'd use that, it gives you an accurate reading for the oil temp inside the engine. The oil in the sump could read cooler since it's in the airstream.

That sounds totally logical to me. The posts I found about using the oil pan were, as I recall, from the older generation message board. I couldn't seem to find anything at all on the subject searching the new generation board, so I thought I'd ask.

Thanks for the reply.
