Hey Guys,

Good day!

I have been puzzled with this oil leak, I already replaced the gasket along the oil pan as well as the gasket on the engine cover but still there is a tiny oil leak that coming along the engine located at the back, I read all the forum and I remember one item saying "oil sender unit or oil pressure unit", any idea where is this located? need help, thnaks.

 

its on the back half of the motor right under,or above your oil filter, also while your back there looking around make sure to check the oil filter cause sometimes they come a little loose and leak just a little bit......it really could be a number of things but i would start there.....Also make sure its deffinatly oil, i know this sounds dumb but old power stearing fluid sometimes can be mistaken for oil.......dab your finger in it and smell it..... the main thing you need to focuse on is just getting under there to take a look.....but yeah to answer your main question the oil pressure unit is directly under/or above the oil filter.....its a one wire plug in and its gonna take a big socket to get it off there i do believe its a 22mm or something like that, not quite sure....they are really easy to change/tighten......get some thread tape to seal it, i had to tap into mine when putting a turbo in my cb7, main problem like i said is just getting under there

 

You can always try to lower your engine a bit to get to where you need to work.

I had an oil leak before on my 96 ex, and low and behold I had the same problem you have.

I feel your pain

 

Thanks for your immediate reply, I will check that, do I have to replace the oil pressure unit or just putting a thread tape to seal it?

 

pic for 1992, should be same

 

Have you tried checking under the dizzy to see if there is a leak there? My 93 EX had a leak dripping down the back but I followed it to the dizzy and noticed the leak. If that is the problem then just get the o-ring from the dealer for $2. It was a ten minute fix.

 

possibly the vtec gasket and also I was thinking the O-ring gasket also on the dizzy.
