Hey guys recently did an oil change (car r33 s1 rb25det) with the same oil i have been using the last like 4 changes(magnatic) and something strange is happaning with my oil pressure gauge now.. let me explain,

usually on cold start up in the mornings it sits just below 6 on the gauge then warms up abit and sits on 4,thats when i take off.

Now after driving for a while it would have dropped a little under 4 unless you give it some and then it would raise pressure accordingly. After this oil change it now drops down to under 2 while driving around and idling also doesnt gain pressure as high when you give it some as it used to,im concerned about this as ive checked my oil level and it seems fine, what could this be?? and what is normal for other ppls oil pressure patterns?

this issues has been covered many times over so try searching. From what you've said the oil pressure sounds completely normal. However if it does get very low than high again (ie from zero then back up to 3 or so)its either a faulty oil pump, or your oil pressure sender.

99% of nissan imports have faulty oil pressure senders (OPS)

this means that the oil pressure is in fact OK but the gauge is getting odd readings due to the OPS being up shit creek

bad news is that those who have put in a new OPS still find that it fails in 6 months or so..

unfortunately the only real fix that we know of atm is to get a different oil pressure gauge :D

      FWIW the depth of the groove in the rubber pad is not super essential, the blocks are rubber and squish a bit. If you are worried an angle grinder will make a deeper groove quick smart

      I mean, if you were to move the jacking points away from the original location, that is, away from the wheels and closer to the centreline of the car, then it will be more likely to overbalance and tip off the supports. Same as we talked about before. I was talking about moving for-aft. If the sill is bent outward or inward, then the car would obviously look unstraight from the outside. Hopefully that hasn't happened either. Again, you can do comparative measurements from the chassis rails to see if there is much deflection.

      Can you elaborate what you mean with your first sentence? I meant move as in the bulge kinda seemed like it got pulled "outward" meaning it got pulled down and to the side with the jacking rail itself, so the load bearing bulge now sits lower than usual and is not level with the sill on the other side of the jack point. Either that or the jacking rail just got pushed in a good bit.

      As well as being risky WRT tipping off anyway. Yeah, I wouldn't expect it to move. Just measure from the rear one to the front one on the good side, then measure that same length on the wrecked side. You will find the notches in the pinchweld, and the jacking pad. Just spray a spot of marker paint or something there.

      but any other area than the bulge you are talking about will just cave in then? The front driver side is pretty bent so I don't know if that will work the way it is now. I can still kinda make out where that bulge is/was but it looks like the position of it also changed due to all the mistreatment? Hard to tell
