Ok so tonight after the Foreigner concert i noticed my oil pressure gauge would drop to zero at idle, ping back and forth between 700-2000rpm, and above or at 2000rpm keep pressure...

im checking the oil as soon as i get up in the morning (and prob gonna go get some, its about that time)


you guys think its the sending unit, pump, or just worn out oil?

BlueKitsune

IMO i think its the sending unit. Ive gone through 2 in less then a year. then I got a 84 Z31 oil pressure sender and haven't had a problem yet.

what all did you have to do to convert it?

BlueKitsune

Just needed an 18mm wrench instead of a 12mm It used the Same Connection and bolts into the same hole w/o modification. A parts store will give you the same part as the 280Z/Xs use so you might need to goto a dealer for the real one. Or a junkyard like I did lol

so thats a 84 NA 300zx?

hmmm $50 new... i might go see if the 300 in my local jyard has one, and pick up a couple 280zx ones while im there

BlueKitsune

Yes 84 300ZX N/A I think the 84 is the only year that will work too. I didnt check the miles on the miles on the Z I pulled it from but it still working good. my gauge seems a little more accurate as well. Cant beat $5 for that XD

ill change my oil tomorrow... if the guage doesn't pep back up to the jyard i go to begin my week with a bang

BlueKitsune

Good call. Make sure to use something with Zinc in it. Or so I was told

280zx2by2

yep... the oil was too low, i guess the pickup was only partially submerged... kinda scary


now i just have to figure out where all that oil went...

BlueKitsune

Water isnt oily is it? Maybe you have a bad ring or something.

280zx2by2

nope never smokes, no oil in the water, and no fresh oil around the head, pan, plug, filter, pump, dist, or rear seal

might be a little getting though rings, that and I didnt do the oil change last time

BlueKitsune

Theres your problem lol

280zx2by2

well i figured ase certified mechanics would do the job right... but seeing as i cant really find where the oil went...

BlueKitsune

Yep go fig huh? Thats why I dont take any of my cars to an oil change place anymore

skib

My cars dont go to shops and never will, the last time one did years ago I got it back with more **** broken then when it came in

280zx2by2

well i was letting my mom drive my car while hers was in the shop, (she also works at a tire shop) and when they don't have business the mechanics will do the oil changes for cheap for the other employees... just didn't know they were about a quart in a half cheap


i was actually mad when she told me about this because i had no idea what oil they put in (from the viscosity and color i can say it wasn't the best lol) and slapped on a low end napa filter... she was just trying to do something nice but thats my fking car lol

skib

lol ya, points for trying to be nice

but im picky on the oil/filter that goes in my car too, the filter in particular


for the love of all things mechanical dont use fram oil filters

BlueKitsune

Ive heard SO many different things about the filters. I just go with Bosh or K&N now

njgheewala

CRAP! I jsut did the oil change and used FRAM, am I in trouble, what's bad about those filters??????

BlueKitsune

Idk Ive heard good and bad things about fram

PurePontiacKid

I haven't had any problems with my Fram filter... Although I'm going to change to a different brand my next oil change...

njgheewala

LOL safe then sorry kind of thing huh!
