hey guys, finally finishing off this build today, and halfway through tuning the oil pump completley lost pressure..... they said on cold start theres a little bit then when warm it ticks loudly and has none. they took the plug off the sump and ran the motor and no oil was pumping out.....so they concluded the pump has failed. its done around 1000 kms......i dont know why or how its failed all of a sudden.

Really? These seem to come up a lot with failures.. Seems pretty weird they are a well known Nismo product.

So is the engine f*cked?

Haha probably doing an engine build myself in the next couple of years and trying to get as much info as I can, along the way.

nah mate engine is fine, happened while dyno tuning so just need to change the pump.

Lose oil pressure and an engine will eat itself at idle if running long enough, yet alone while being run on a dyno.

And they removed the sump plug, no oil came out, and they can't work out why it has no oil pressure? Maybe because there's no oil in the sump...

      It only looks tidy, as most of the stuff that was on the whole back wall, is now in the trailer to go to the tip, or has been shoved in my 2.2x2.4m "Spare parts room", and now I can't get to anything in there Ha ha ha I could definitely do with a bit more space, but I'd just end up with your problems I'm going to enclose the car port beside the garage, and move a lot of stuff into it I think. OR... It will be setup as a fabrication area, and the main garage will have parts storage in it. I'm not sure yet... Need some pictures of that big shed you've got with the bikes and Skyline in

      No. I think it's gone. 😭 I think you can get body coloured ones on eBay so I think I'll get one of those... Or just hang a red ribbon from the hole and whack a TOW sticker next to it.

      Can't say I've had a bad experience with one on my car, then again it only gets washed once or twice a year... The wheels on the other hand, get a good spray often due to my shitty dusty pads.

      @MBS206 thats pretty neat and tidy to me!  I'll get a photo of mine when I'm out there next. It might require multiple photos to understand the scale of the atrocities though... In total I have 4 sheds of varying sizes and layouts. Main shed is 14x8, second shed is 3x8, third shed is 11x2.5, fourth shed is around 6x4.  All are pretty much full.   The main goal of my cleaning tsunami is to make the main shed predominantly car and motorbikes only. Second shed is my metal fab room (2 x bench grinders, drill press, bench belt sander, metal band saw, scrap metal storage and some of my garden tools.  3rd shed is more bigger garden stuff, storage for engine crane, jack stands, concrete grinder, concrete mixer, air compressor lives there, and it now has two 2mx2m pallet racking shelves with itemised boxes holding building stuff, electrical stuff, plumbing stuff, etc, etc.  The 4th shed is Ryobi electric ride on mower, mini boom sprayer, ancient Kubota tractor, more garden stuff!  I have got a lot of shit....  Then there's the pool house (8mx4m) and the pool pump shed (4mx4m).  I built all of the sheds over the 11 years we've been here.  The main shed was a Ranbuild kit, the rest are all custom made to fit the areas available. Building the main shed taught me a LOT as I had no idea about building anything prior to that!  I've still got one more in me. It will be my man cave which I poured the extra concrete for way back when I poured the concrete for the main shed. The idea is the Skyline will be a centre piece of the main cave once (if...) it's finished.  I told my now 14 year old son yesterday that I will 100% drive him to his year 10 formal in 2 years. Still a long way off but at least I now have a date to work towards! 🤣

      Modern oils are amazing. Add tyres to that as well.
