Hey guys. I know this has been covered many times, but i could not find a directly related info for 250GTs. So i apologise

Planning to take it in for a full service tomorrow. Just need to know what sort of engine oil is best for the VQ25DD. Also, if i wanted to do a transmission flush, which brand/type would be best?

I've got some pretty loud ticking noise coming from the engine which i'm sure is coming from the fuel injectors. Any tips on how to fix these? A clean or replacement?

Thanks in advance

- Fill up your car with a full tank of petrol

- Run Nulon Total Fuel System Cleaner *before* changing oil. Reason being this will allow all the crap to get into the old engine oil, instead of the new oil.

- Castrol Magnatec 10w-40 for engine oil.

- Castrol Transmax Z for transmission.

Do not use "flushing agents".

Awesome. Thanks for that. I think it's too late to use the fuel system cleaner now, service is due tomorrow.

The ticking is so annoying! It's either the fuel injectors or a bad lifter. We'll find out tomorrow i guess.

Cheers

Engine oil change is a must.

You might want to check your timing chain. That could be the source of the ticking noise. What is the mileage of your 250GT?

Done servicing with all castrol oils. Runs really, really smooth now. Improved shifting as well due to the new fluid in the gearbox. But the damn ticking is still there. They said it's normal.

i might try the injector cleaner this week and see if it does anything. If it doesn't i'll look into the timing chain.

      Lets play a game - What is causing my oil consumption?

      Hopefully it ends up being something manageable, like a hone, rather than a full bore—it would be a huge relief if it’s not as bad as it looks. Hang in there; these setbacks are annoying, but it sounds like you’re handling it as smartly as possible.

      Are RBs worth building reliability wise

      At the end of the day, it’s all about understanding the odds and being comfortable with the potential cost, whether it’s horsepower on a build or chips on a roulette table. And I have to say, the Laine example made me laugh—some people really do embrace that carefree, “roll and see” attitude!

      Thanks MBS206, i got that PDF but got abit overhelm with all the connections and tracing of wires. I wasn't expecting to plug the dash harness anywhere. i was just going to use my electronics jumper wires to plug into the right pins like ECU power, ecu ground, ignition trigger etc... I do have a few ratchet straps locking it down tight. Fire extinguisher ready and only a small amount of fuel at a time, enough to submerge the pump.

      https://yariksteel.ru/manual/R33/Skyline_R33_elektroprovodka.pdf   Page 18 should be what you want for the Dash Cluster wiring. Though, you don't need the dash plugged in to get the motor running. What you want is power as how GTSBoy said. You need to power the ECU. Find in the above link the ECU pin outs (Verify them before just connecting them up from things written on the internet). Find anything needing power, give it power, find anything needing ground, give it ground. Then give the starter motor power through a big cable, and bridge the solenoid on the starter straight to power too.  ECU will be on, and when you give the starter power, it'll spin the starter motor, and it should start. I also hope you have a proper stand, and not just the engine sitting on some wood. You will want it bolted down properly.
