Ah right. I guess the CAS is also related to that?

When you say timing wasn't right are you referring to the timing belt being a tooth off? I think my AFR's are f**ked but will find out soon.

Sounds overkill lol.

Will do.

I'm just relaying what my mechanic told me. In my other post i talked about sonething similiar but some mechanics said to me that black smoke "can" be normal. But I'm out of my depth here. Ecu is usually under the driver footwell? Or ive seen it sometimes on passenger footwells. Couldn't see it either. If it hasn't been tuned, is it even possible for a car to run well (meaning it feels normal when driving, not thinking about A/F ratios and such) if it hasn't been tuned on a aftermarket ecu? Either way needs a tune, I'll leave it to the professionals.

That's the thing I have no idea who tuned it and not sure if it was dynoed, and is why I need to get it tuned because I don't have paperwork. In regards to the ecu, I checked that a while back and I couldn't find it lol, it is aftermarket though my last mechanic told me. Anyhow I'll just leave it for the tuner.

Ah ok, cheers. When you say it won't do anything do you mean the ground will no longer work or nothing bad will happen or both?

All valid. It's tuned but a poor tune lol. I'm only inspecting the oil because I did more pulls that usual as mentioned. If I don't do any pulls it stays clean for a decent amount of time, but I will get it fixed! It's just taking forever because everyone is busy.

I noticed my earth wire was disconnected when I attempted to do some work, but the wire was yanked off with the bolt still attached to the exhaust manifold heat shield. I used an aluminium connector to replace it from super cheap like this, will it melt? I was worried as the old one is steel. https://www.supercheapauto.com.au/p/sca-sca-electrical-terminals---ring-eye-5.0mm-red-25-pack/120047.html?cgid=SCA01060604#start=48 I removed the rubber of course as that's going to melt.

Alright, I believe you 😂 Many my original mechanic has gotten a lot of things wrong lol.

Not the wastegate solenoid, he was saying the actual boost controller. The vacuum line going to the boost controller he said just to tie that up so I don't have a boost leak.

I'll double check the model. I also got told though from my mechanic I can plug it out as well and I'll go back to wastegate pressure or something like that?

I'm not sure how to do it, I'd rather leave it to the tuner, the thing is I think it probably technically runs rich when I drive normally as well I just don't blow smoke (unless I do a hot start a bit of black smoke leaves the exhaust, but never have smoke on cold start)

Cheers

Ok cheers. I'll get that tune asap then and probably even do an early oil change.

I noticed my oil on my rb25 stays gold for about 3,500km roughly. Then goes light brown after that. Probably around 4,500 mark it goes dark brown (this is me driving normally with no / minimal pulls as i blow black smoke when i boost) (when I drain the oil it's black at 5,000 no metal shavings though in the filter or oil) I noticed now that it's been under 3,000km and it's dark brown. I think it's because I've been doing a few pulls more than usual (pulls means, in first gear going up to 5000-7000 rpm) My oil doesn't smell like fuel at all, and isn't causing me any issues but I don't want to get bearing wear (yes I'll be getting my car tuned soon to) I don't know if it's just me or if my oil is a bit thinner (I'm comparing brand new oil to oil that has roughly 2,500km from memory so might not be a good comparision.

What are your thoughts on using the red Permatex stuff? My rocker cover uses that and I didn't want to mix it incase it causes problems. Or maybe I'm overthinking it.

Does anyone know when removing the throttle body if you can re use the throttle body gasket?

Ah right, mine has probably been thrashed by one of the previous owners lol but I baby it. Cheers!

Is that a design fault by Nissan then?

Ah ok, yeah for the r34.

Ah right, I wasn't going to mess around and install extra crap. Surely it should work right out of the factory lol

I'm not sure if skyline's have it, I haven't been able to find info on it.

There is no seal, that's the thing.

Not until I googled it, now I remember lol. Seems like it's just to clean it up. But it doesn't stop the leak, I have a leak issue though? Thinking whether I need a new bottle, surely not lol.
