Hey Guys!

This may be a slightly long story, but please read because it may provide some clues.

I was on a cruise and basically I cornered too fast (Stupid I know) and lost control and spun out. I wasn't trying to be a smart arse, just trying to get somewhere in a hurry. I was extrememly lucky in more ways than one. I backed over one of those aluminium white reflector things that are on the side of country roads when I stopped spinning (only did 270deg). I feel like an absolute tool and an idiot for going too fast. I tore loose an Earth wire which in turn blew an ignition fuse. This lead to no dash instrumentation and no power windows and best of all stopped my alternator from charging my battery. Once the fuse was replaced, everything was working again. I have checked underneath the car and can't find any damage from the reflector post other than the obvious wire that was torn loose. This leads me to today.................

When I was going to a mates place I noticed that the oil pressure gauge was getting really high when I was pulling high revs. even around 4g on the rev tacho, it was reaching the line between 4 ang 8 on the gauge. It was almost hitting 8 when I was pulling over 5.5-6 g on the revs. I don't think that this is normal, but I can't verify it as I don't know anyone who has a skyline presently. I can't see any oil leaks and the oil level looks good.

I have a S2 R33 which is stock except for a pod filter.

If anyone has any ideas, please let me know. I will probably have to take in to a mechanic (anyone know anyone around the woodville area?) maybe morepowa or some place like that but at least I will have a possible clue as to what I am looking at.

cheers

The stock gauges and senders are notoriously inaccurate and can read either extremely low (most common) or in some cases extremely high. Mine does both from time to time.

Get either a cheap mechanical pressure gauge on it to test or shove a decent elec gauge (~$100-150).

Oil pressure too high or too low can indicate engine problems so get it checked out. :banana:

I think from memory that mine stayed relatively constant.

I did notice however it is more exaggerated when the car is cold as opposed to when it gets up to temperature.

any more thoughts?

will be getting it checked out a.s.a.p. though. can't afford a new engine. :banana:

thanks

If the motor was cold and your pulling high rev's expect to loose a bottom end in the future.

As a general rule don't give the car a hiding until ~10mins after the water temp has reached normal operating temp as the oil is still cold and thick. Thick oil = less oil flow.

If you loose a bottom end there's a reason for it; either you have given it shiet when its cold, there's been detonation or oil starvation at some point.

  • 3 weeks later...

make sure you do i was in the same situation than you with my freshly rebuilt motor, everyone kept telling me its the gauge or sender and i didnt bother checking it out, and then my oil pressure light came on and now my engine is out again, so i would suggest putting a mechanical gauge to it asap, and if it is running low oild pressure it might be time to replace it before it does some serious damage. Well worth it for piece of mind. cheers

    • Next on the to-do list was an oil and filter change. Nothing exciting to add here except the oil filter is in a really stupid place (facing the engine mount/subframe/steering rack). GReddy do a relocation kit which puts it towards the gearbox, I would have preferred towards the front but there's obviously a lot more stuff there. Something I'll have to look at for the next service perhaps. First time using Valvoline oil, although I can't see it being any different to most other brands Nice... The oil filter location... At least the subframe wont rust any time soon I picked up a genuine fuel filter, this is part of the fuel pump assembly inside the fuel tank. Access can be found underneath the rear seat, you'll see this triangular cover Remove the 3x plastic 10mm nuts and lift the cover up, pushing the rubber grommet through The yellow fuel line clips push out in opposite directions, remove these completely. The two moulded fuel lines can now pull upwards to disconnect, along with the wire electrical plug. There's 8x 8mm bolts that secure the black retaining ring. The fuel pump assembly is now ready to lift out. Be mindful of the fuel hose on the side, the hose clamp on mine was catching the hose preventing it from lifting up The fuel pump/filter has an upper and lower section held on by 4 pressure clips. These did take a little bit of force, it sounded like the plastic tabs were going to break but they didn't (don't worry!) The lower section helps mount the fuel pump, there's a circular rubber gasket/grommet/seal thing on the bottom where the sock is. Undo the hose clip on the short fuel hose on the side to disconnect it from the 3 way distribution pipe to be able to lift the upper half away. Don't forget to unplug the fuel pump too! There's a few rubber O rings that will need transferring to the new filter housing, I show these in the video at the bottom of this write up. Reassembly is the reverse Here's a photo of the new filter installed, you'll be able to see where the tabs are more clearing against the yellow OEM plastic Once the assembly is re-installed, I turned the engine over a few times to help build up fuel pressure. I did panic when the car stopped turning over but I could hear the fuel pump making a noise. It eventually started and has been fine since. Found my 'lucky' coin underneath the rear seat too The Youtube video can be seen here: https://www.youtube.com/watch?v=uLJ65pmQt44&t=6s
    • It was picked up on the MOT/Inspection that the offside front wheel bearing had excessive play along with the ball joint. It made sense to do both sides so I sourced a pair of spare IS200 hubs to do the swap. Unfortunately I don't have any photos of the strip down but here's a quick run down. On the back of the hub is a large circular dust cover, using a flat head screw driver and a mallet I prised it off. Underneath will reveal a 32mm hub nut (impact gun recommended). With the hub nut removed the ABS ring can be removed (I ended up using a magnetic pick up tool to help). Next up is to remove the stub axle, this was a little trickier due to limited tools. I tried a 3 leg puller but the gap between the hub and stub axle wasn't enough for the legs to get in and under. Next option was a lump hammer and someone pulling the stub axle at the same time. After a few heavy hits it released. The lower bearing race had seized itself onto the stub axle, which was fine because I was replacing them anyway. With the upper bearing race removed and the grease cleaned off they looked like this The left one looked pristine inside but gave us the most trouble. The right one had some surface rust but came apart in a single hit, figure that out?! I got a local garage to press the new wheel bearings in, reassemble was the opposite and didn't take long at all. Removing the hub itself was simple. Starting with removing the brake caliper, 2x 14mm bolts for the caliper slider and 2x 19mm? for the carrier > hub bolts. I used a cable tie to secure the caliper to the upper arm so it was out of the way, there's a 10mm bolt securing the ABS sensor on. With the brake disc removed from the hub next are the three castle nuts for the upper and lower ball joints and track rod end. Two of these had their own R clip and one split pin. A few hits with the hammer and they're released (I left the castle nuts on by a couple of turns), the track rod ends gave me the most grief and I may have nipped the boots (oops). Fitting is the reversal and is very quick and easy to do. The lower ball joints are held onto the hub by 2x 17mm bolts. The castle nut did increase in socket size to 22mm from memory (this may vary from supplier) The two front tyres weren't in great condition, so I had those replaced with some budget tyres for the time being. I'll be replacing the wheels and tyres in the future, this was to get me on the road without the worry of the police hassling me.
    • Yep, the closest base tune available was for the GTT, I went with that and made all the logical changes I could find to convert it to Naturally Aspirated. It will rev fine in Neutral to redline but it will be cutting nearly 50% fuel the whole way.  If I let it tune the fuel map to start with that much less fuel it wont run right and has a hard time applying corrections.  These 50% cuts are with a fuel map already about half of what the GTT tune had.  I was having a whole lot of bogging when applying any throttle but seem to have fixed that for no load situations with very aggressive transient throttle settings. I made the corrections to my injectors with data I found for them online, FBCJC100 flowing 306cc.  I'll have to look to see if I can find the Cam section. I have the Bosch 4.9 from Haltech. My manifold pressure when watching it live is always in -5.9 psi/inHg
    • Hi My Tokico BM50 Brake master cylinder has a leak from the hole between the two outlets (M10x1) for brake pipes, I have attached a photo. Can anyone tell me what that hole is and what has failed to allow brake fluid to escape from it, I have looked on line and asked questions on UK forums but can not find the answer, if anyone can enlighten me I would be most grateful.
    • It will be a software setting. I don't believe many on here ever used AEM. And they're now a discontinued product,that's really hard to find any easy answers on. If it were Link or Haltech, someone would be able to just send you a ECU file though.
