grrrrrrrrrrrr

the guy from VDO emailed again, and even with the nissan part number that i gave, he still says there is no VDO item!

I gave him the part number that was in the aus300zx.com website to see if he has that in his stupid computer. i have no idea why its not coming up as a listing...

will keep you posted.

ok more bad news..

the moron at VDO who is emailing me, still insists they don't have a OPS for us

he won't confirm that the 300zx sender works at all.. he is dodging the question coz he is a f**king moron

i'll have to do some more searching i think

is it 100% confirmed that its the same sensor for 300zx/R32/R33??

what about any other nissans

thanks

Just some observations that might help:

1. Genuine OPS from Nissan is around $150 (trade....add maybe $20 for retail).

2. OPS PN is 25070-30P01 (R32 GTR and GTS4, R33 RB25DET and Z32 300ZX). FAST does show an alternate number for some models (25070-55S60), but it also shows the -30P01 as the direct alternative.

3. The VDO OPS shown on the 300ZX link looks identical to the type fitted to local spec R31 Skylines (RB30) as standard. VDO supplied some parts for Oz spec R31's, inc the instrument cluster and some other sensors, basically to build up local content. Be warned that quality is not great.

well spokt to some people who have done this on their 300zx, and they have confimed that te unit does work fine, but still suffers from the same problem as the stock OPS

this leads me to believe that the problem is not the OPS unit itself, but something aboutthe way it is mounted or connected

there's nothing wrong with the stock OPS...

the only thing wrong with them is the fact that they're getting close to 15 years old and as such, are f**ked.

what happens is the rubber seal around them fails, and lets oil inside the unit itself.

from what i've heard, if you replace it with another factory one (or in this case a VDO one) it should be fine for another 15 years.

*note* this is what i've been told in terms of why they play up etc

well i have spoken to a good mate who is a member of aus300zx.com

he said he changed to the VDO sensor and it failed in 4 months

then he changed to the stock sensor and it has been ok for about 6 months so far

BUT.. he did some kind of electrical modification to the OPS before he putit back on

apparently (according to him) there's 2 plugs on the OPS, but the stock wire only connects to one of them

He grounded the other plug to the chassis... and he hasn't had a problem since...

apparently an autoelectrician told him to do this

I want to try it out, but haven't had time to try and get to the OPS

Hardcore thread bump.

Has any one used an aftermarket oil pressure sender to replace the factory unit?

I want to wire in an aftermarket oil pressure sender into the Vipec as a fail safe (if it sees less than 5psi to shut the engine down) but want to do it with a new oil pressure sender as my stock one acts up.

      I also think it comes down to the dollars spent for quality items, there's some cheapie versions out there, which look fine, but, there are versions of much higher quality out there, but, you obviously pay more for the quality of materials used and quality control When I first got work done by Advan Performance on my old R33 the silicone joiners were cheapies and actually blew out on a joiner heading to the plenum, when I then took it to Unigroup they said that the silicone hoses they used and were junk, Unigroup replaced every hose on the engine with much higher quality items and from then I never had a issue with any hose Additional cost and quality gets you quality silicone base materials and quality reinforcement fabric stuff As for OEM rubber hoses, again, quality materials and strict quality control will give you quality hoses, but only to OEM spec, I believe using quality silicone replacements is a upgrade I  saying this I have only dealt with vehicles I own and play with

      Not gonna lie my sense of smell isn't the best. But it does look more grey to me. It doesn't smell like oil, friend says it smells like fuel.

      That's it. Too rich for me. I'm out. If it does start to sell in pieces, I'll probably register an interest in the diff & axles, gearbox & tailshaft, and maybe the brakes.

      I tried my best, well I see how it is though... It's time to be ruthless! I'll up my bid with a JVC sub and an amp to run it, 8 stainless steel drink coasters with a rubber backing, and a photo of Tom Cruise. Oh, I can increase the cash portion by 20 cents if that helps.

      Or if it's grey, is it watery? Does it do it after you've been for like an hour long drive it will still do it, or just near the start of the trip? As GTS said, does it seem like oil (blue), water (white/grey) or fuel (black)? Sometimes the colour can be hard to see clearly too for what it is, as GTS says, what's it smell like?
