the oil pressure gauge in my 1994 r33 gtst droped to below one yesterday, no warning light came on however. the gauge now varies in oil pressure depending (from what i can gather) on revs. for exaple when i first noticed the oil pressure i was at a set of traffic lights and i only drove it far enough to pull over, as i drove off oil pressure picked up tp about 2/3 and droped again once i took my foot off to about 1 and jus above 0 when i pulled over. in 4th doin about 90kms/h the gauge will read 4ish and then put it in 5th or take my foot off and it slowly drops. oil level is fine as this was the first thing i checked. im going to check the sender unit this weekend and i dont plan on driving the car until this is sorted. please if you have any ideas or know of any common problems with oil pressure with the r33 let me know any help would be much apreciated.
