Hey

I've done searches in regards to this, but there are differing opinions and not many proper answers...

I've dumped oil plenty of times. This time though, after letting the oil drain for about an hour, I went ahead and put in fresh oil. But I've accidently overfilled...

It's 4L engine + .4L oil filter on a RB20DET. Engine has done 150k.

I put about 4L in, let it sit, had a look at the dipstick and it showed above H. Went for a small drive, let it sit again, but still sitting about 4mm too high. The dipstick shows the oil level about 4mm above max. and it just touches the letter H.

Should I drain some out?

Cheers

Nah no dents, sump is all good. A fair bit of oil must have remained even after draining...

I think the best thing to do is simply get it at the correct level.

I'll see if I can drain some without undoing the plug completely, otherwise I'll dump the lot and then put it back in at the appropriate level.

Just to recap.

You come on here asking if the oil overfill is ok.

2 people say it is ok.

You somehow decide you should drain it.

Seems odd.

I don't know why you'd say that, I get asked for help all the time and it goes roughly like this:

*phone rings*

Me: "Hello"?

Caller: "Hi I need your help with X, it's doing Y"

Me: "I know what the problem is, you need to do Z"

Caller: "I don't think so, I reckon it's.............."

every. single. time.

I think people are just f*cking useless at asking for help.

To weigh in on the original conversation I fill between the H and the hump on an oil change (in an RB25 you can just dump 5L in if you have drained it on a level surface). I assume the hump is the danger zone much like there's a hump on the low side as well.

    • 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?
