Hello!

I have oil leaking/weeping from the front of this sensor just below and to the left of my oil filter. Can anyone tell me what sensor it is (oil pressure?) and if I should replace the whole thing? I have had no luck tightening the screw at the front which is where it is leaking, at the very front just behind the screw.

Thanks for any help

Your oil/water exchanger is in the picture, it might be leaking oil from there.

it was leaking from there but I replaced the seal and its no longer leaking that's on old photo, I'm actually watching it leak from the sensor with the engine running.

Don't over tighten it, you might wreck the thread. Take it off, clean the oil off the thread on the sensor and in the water/oil exchanger with a can of brake or carby cleaner. Use some gasket sealer on the thread of the sensor to help seal it when you do it back up.

I have only tried tightening the screw on the very end of the sensor not the whole sensor screwing into the block but yeah I didn't move it much and it didn't help. Do you have any idea what the sensor is? if i'm going to remove it i may as well replace it, id hate for it to leak if I cleaned it and put it back on

It's leaking from the thread isn't it? You don't need to replace the sensor if it is.

Not the thread where it screws into the block no, the sensor itself is leaking from in front of the black plastic part behind the silver screw that's circled in the pic

now I'm having an interesting and annoying problem lol, the new sensor fits in a 1 inch socket but the old one is slightly larger, a 26mm is to small and a 27mm is too big as is a 1 and 1/16! WTF it's driving me mad I think I'm gonna chuck vice grips on it if it's possible I'm so damn angry haha.

    • Yeh I think i'll message an old contact i had for ages that manages his own tyre shop now.. n tell him what i want n work with him before ordering..  Got this 17x9 +30 Driftteks on 245/45/17 PSR Drag Radials on the rear.. They fit well - for your reference in future - Rear guards  have been lipped in & minimal to non flaring of the rear Gaurds.  
    • If only it were that easy! I also needed to remove seats, shocks, brake calipers, send my car through a fence, and use measuring and ended up guessing because I didn't remove seats, shocks and brake calipers. It can be hard sometimes Can be a little more complex than 'just measure' if you want to truly measure the entire wheel through all of it's suspension travel. But if you aren't going for every last mm then yeah, you can check the space you currently have and guesstimate.
    • If you own a car, and it has wheels on it, and you know the offset of those wheels, and you have a measuring device, you have everything you need to work out if other wheels will fit.
    • Will this fit? but they are staggered set - RAYS 57DR SEMI GLOSS BLACK 18x8.5 +37 | 18x9.5 +38 5-114.3 STAGGERED SET   or If no go could just get a set 4's wheels of 18x8.5 +37 5-114.3 - would i run 8.5's 235s up front n 245's at the back if I do?   Thanks.        
    • Put a clamp on your return line. I have a feeling it's sucking air, and introducing bubbles to your fuel. With a lot of fuel, less problematic. I'd honestly be redoing all the lines in the tank and clamps on everything.   Also, you've given two different answers to the same question: Asked if being followed by the police you could get down to use the whole tank, you said yes you could, so long as you keep off boost. However, you then followed this up that free revving, it would also cause the issues. I'm doubting free revving is enough to make any noticeable boost on what is likely a decent sized turbo.   So now I have to ask, can you actually drive it lightly and use all the fuel, or does it break up even free revving? Also, have you put a fuel pressure gauge on it? Can you hear the pump change noise at all when you're having this issue?
