Has anyone had any issues with engine knock on a standard car before? Where it knocks almost every time I go to put my foot down!
This is my 4th R35 having had a 2009, 2013, 2016 and now this 2017 and all my previous cars I never had any problems with engine knock at all. I put 99 Octane in and have tried different petrol stations of Shell and Tesco to rule out any fuel quality issues but still I get engine knock almost every time I go to accelerate hard like for example joining the motorway on a long straight slip road and no traffic.
Its a pain because the car sort of goes in to a half limp mode and restricts boost to 10psi etc and any car you may of just overtaken is now going back past me looking at me wondering why I'm suddenly slowing down. Plus as soon as I turn my ignition off and back on again it goes back to normal however that's the last thing I would want to do is stop on the hard shoulder and do a reset so I just wait until I get off the motorway and stop safely. Unfortunately though it means I'm forever driving around in a GTR with half the power plus I'm concerned now that each time there is engine knock that the engine is getting damaged.
The car is still under warranty until October and so I'm keen to get this fixed by Nissan under warranty and before it runs out. So far when I took it in they only cleared the code and today I'm going back in because it happened 2 days ago and the technician is going to read the "Freeze Frame" data and send it to Nissan to see if they can establish what is causing the engine knock.
Is there anyone on here that can help answer a question I have please - I'd like to know if all these engine knocks I've been getting could of caused any internal engine damage? and if so should I be insisting on a full engine inspection / replacement or is engine knock not that bad?. I've read conflicting stories however just because Nissan actually fit a Knock Sensor then I would say it's not a good thing for an engine otherwise they wouldn't fit a sensor in the first place however if the sensor can act quick enough to stop any damage from happening then that's a good thing however I'm not a GTR Technician.
If anyone has any advice on whether my engine could of been damaged then I'd very much appreciate it.
Thanks
