Rb25 Oil Leak

[horrace]

Hello any help would be great,

My C34 is currently leaking oil from near the oil filter, I'm 99% sure its not the oil filter because when i grab it with clean hands the filter and the filter block are clean. It looks like its coming from the part in the pics iv attached it might be the factory oil cooler? not to sure just wondering if anyone knows of a common leak that can develop in this area? I cant get a good look in there and I have big hands LOL, also its leaking a fair bit of oil so I need it fixed asap.

thanks guys

Even in the first picture that oil cooler doesn't look to be seating properly. You might need to take it off and inspect the threads and replace or install correctly?

hhmmm ok its due for an oil change so ill try that when i have the filter off, is that what that thing is> the oil cooler?

going by this one on ebay it looks like its all one piece so it must be leaking between itself and the block one would think.

That's an iunisual place for an oli leak, the cooler is a bolt on arrangement and unles you have removed it there sholud be no problem, how much oil are you loosing it might be coming from above, cam covers are prone to coming loose, try tightening the covers maybe.

I have a remote oil filter in which I have oil temp and oil pressure sensors for dash mounted gauges. I run single din and gauges fill space.it is cool and practical.No leaks.

It is loosing a bit, a little 10cm puddle when I park over night. It has never been removed as far as I know. I did look to see if it was coming from higher and didn't see anything but I'll have a proper look tomorrow again.

I recently had mine leak from the same place removed cooler and replaced the large rubber oring bingo no more leak, so yes they can leak from there

[horrace]

Oh really well at least I know it can be done, was it hard? where did you get the did you get the o-ring? also any tips?

Nissan? Its usually the best place to get parts for Nissan's.

Hello again fine sirs! after repairing the first oil leak i have found another, oil is seeping from the very front of the sensor to the left/below the oil filter. Right from the front just behind the screw that holds the tab/electrode thing for the sensor wiring. Now is this the oil pressure sensor? i'm thinking it may be best to replace the whole thing? any advice?

cheers guys, this is really starting to shit me!

If it's leaking through the sender; it's time to replace it.

Give it a good degrease and make sure that it's not running down the outside.

[horrace]

yep definitely leaking from the centre of the sensor, I'm keen to replace it if I knew what it was! I may just ring Nissan and they can find it in fast?

Agreed with Dale. Hey Rhet, does your oil light on your dash work? I was wondering from viewing the first pic why it was disconnected. That brown plug flappin' in the wind in the pics should most likely be connected to it..........

[horrace]

yeah I pulled it off to check the leak it's usually connected, my oil light still works on start up with it disconnected though so f**k knows.

Massive thread revival.

I have what looks to be a leak from around the t off for the oil cooler as in the above pics.

Was it hard to get in there to remove and replace the big o-ring? Did you need any special tools or smurf hands?

[Hadouken]

Smurf hands are a must!
