and the fun continues

[rejeep]

driving around town home for lunch I took out the rover to put some miles on the new engine before it goes away for the winter...

driving down the road the GREEN light came on..
quickly pulled over, wires, engine, and dipstick were all "ok"

I haven’t had a chance to pull the sender yet and check for pressure..
but has anybody had this happen to them?

I’m thinking it’s more likely a wire ground or something..
any reason a new rebuilt motor would just loose pressure after only 15 miles.

i hate dummy lights
i ended getting rid of the stock series 3 oil gauge setup and throwing in a 16 dollar mechanical gauge. its worth the piece of mind and there were so many things in the stock electric setup that could go wrong.not to mention the fact that the land rover parts aer through the roof.
sorry again RN

its worth it just for piece of mind.

well i do have a nice smiths dual gauge that i have not had the time to install..
I was planning on doing it this winter when I had a few moments..

I did grab a cheap gauge from downstairs that I will hook up in place of the sender to test it tonight..

just stinks becuase I finally had a day to drive around and put some miles on it.. I dailed in the motor at lunch and then this of all things..

[73series88]

sorry that does stink

is the spin on adapter a different size then standard NPT thread?
mine seems to be

If it is the Rover 2.5-type spin-on adapter, it's likely metric M10x1

[rejeep]

that what I figured.. the stock sensor fits in, but the generic oil gauge I have does not..
have to hit the brass cabinet tomorrow and find an adapter..

I cranked the motor over with the coil wire pulled and the sensor out..

had a nice little puddle of oil in the driveway..

looks like I have an electrical issue or a bad sender... Go figure..

[SafeAirOne]

I have the opposite problem with my crappy sender. Occasionally it sticks in the "everything's fine--don't worry about it" position, so I don't get the green light before startup sometimes.

I've heard there's a wrong way to install those spin on adapters. Installing it upside down will block the return passage, or something along those lines. I think the issue has been discussed on this board in the past. It might be worth investigating.

EDIT: Here's a discussion worth reading.

[rejeep]

yeah I installed it on the engine stand with the "TOP" in the "TOP" most position..
the adapter is on right.. but good thought..
I even checked to see if the filter had an issue..

I am going to the shop tomorrow to grab my old sender.. the one thats not reading right was a new unit..

this might prompt me to instal my gauge a bit sooner..

[rejeep]

Well they don't build them like they use to....
My 30 yr old sending unit fixed the problem, while my new one crapped out in less than 30 min of run time...

next question is.. Is there an adapter out there for the sending unit so I can tie in a mechanical gauge.. I spent some time in front of the brass cabinet today without any luck

Holden has everything you need to run both a mechanical oil pressure gauge and the idiot light simultaneously. First you'll have to confirm the thread pitch on the existing pressure switch.

[rejeep]

can anybody confirm for me what the stock oil pressure sender is?

Presumably for a 2.25? My 2.5 is M10x1 but it's a different part # than the 2.25 switch, which looks like it has a different thread pitch.

It MIGHT be 3/8" BSF (you want to confirm this because I'm just going by the description of this 'T' piece adapter on the Holden site).

[rejeep]

I think its 3/8 BSF as well..
I just ordered that adapter..
but also thought that the spin on adapter I have has 2 ports.. im wondering if they are both the same BSF pitch or one is different for a mechanical gauge??

well since were on the subject..
the Dual Smiths gauge I have also has this for the coolant temp..





I cant for the life of me figure out if I need another adapter for this or there is a plugged water jacket somewhere that I must have missed..

any idea?
