1995 Disco 5 speed manual learning curve

[joeblack5]

Prefilled with rotella 15w40 and installed the larger wix aaaaa filter. Cranked 20 sec with fuses for injection and fuel pump out. Then started and it took another 20 sec before oil pressure was there. The fuel PO pressure went up 2-3 psi at idle cold... From 32 to 35. Same behavior with revving the engine up dropped the oil pressure 2 psi.

I will make screw adjustable washer / shim for the oil relief valve and see what that accounts for.

I need to review the whole oil passage thing. That looks like the red arrow is going down the pickup to the pan(?).

It seems a remote filter housing with a pump or accumulator would be quite nice.

 

[joeblack5]

Another cold start test with the wix low bypass filter. No modification to relief valve yet. Pressure starts to builds up in 1 second and passes 10psi in two seconds. Maxes out at 37 psi at idle cold.

Next will be adding the relief valve pressure adjuster to it.

I have been looking into electric oil boost pumps and am not really satisfied with what I have found so far; the affordable ones are mostly gear pumps.. which tend to shed metal. It may be necessary to convert a drysump scavenger to electric.

That said, an accumulator would be relatively cheap and easy; one thing about accumulators I have always wondered about though: are there edge cases wherein the extra oil finds it's way into the pan? a couple extra quarts is a LOT... I'd hate to hydraulic a motor from an overly protective accumulator overfilling the pan.

This scenario comes up at every oil change (unless you remove the accumulator and pre charge it as you would for a fresh engine). Never caused me any grief.

I'm engaged in the same battle. Need to mount two analog, mechanical, gauges and the options are few.

This is what I did.

 

[Greg_M]

This is what I did.

Very nice! I like the tidy install that's not on the dash top.

 

[robertf]

I threw this up there a long time ago. maybe its of use

This is a copy of the posts on the oil pressure thread...


Well some progress. Made an adjustable shim. Took the circlip and oil relief spring out.
Used a threaded rod in a frame home that is nice inline with the oil pressure relief cap to push the whole assembly back in

Oil pressure cold low middle.40 psi.
Adjusted my shim about a turn..44 psi.

 

[DiscoClay]

wow. This is getting really interesting.

 

[joeblack5]

Cold start this morning.. oil pressure gauge starts to move after one second and on 44 psi after 3 seconds .
Now it is much warmer, like 62f so this data point does not mean al that much.

Took it for a drive ,outside temp around 65f. Immediate pressure on starttup, climbs to 42psi within 3 seconds.
Climbed a 11 % mountain for about 1 mile, went down and up again.
Oil pressure at idle 14psi climbs to 30psi at 1500rpm. Does not go above 40 psi at any rpm once hot.

Oil pressure drops with 4psi when accelerating and increases again when letting go of the throttle. I assume my crankshaft moves forward and backward a bit, maybe because of the manual clutch has worn the axial bearing a bit??


Either way installing and oil pressure gauge gives valuable information.

Something different.. the brittle center console.. trying to make some aluminum reinforcements. Starting the cutouts for the transmission levers.

Can you pop in a few more pics?

Well, my love affair with disco 1 came to an abrupt end.. trying to avoid a broken car on the road and paying more attention to the broken down car then what was happening in front of me.. about 25- 30 mph.. tried to avoid the Merc but hit them anyhow.. sad story. Nobody hurt , so that was a blessing. Disco was undrivable. Front driver axle shifted 2" backward.. and steering bend, not sure how that happened.. frame seems to be ok.

Bummer. Time to regroup and spend some insurance money.

 

[joeblack5]

Thks Greg, not insured like that and no doubt a financial total loss for this 1995 if it would have been.

Looking at it again. Seems that the axle mount has bend back wards 1-1/2" ..probably push that back with hydraulics and or sledge..

I cannot find the paint code.. looks like the original paint.. is this something that is linked to the vin number? Would be nice to find a fender with the right paint on it.

Front track bar and rear steering bar bend. Bullbar broken and then some small stuff. The radiator support pushed in about 3/8". On the driver's side.

Will start with pulling the fender of and see what is under there besides rust.

Do not feel like a prince but dark for sure.

Landrover Newby here.
I have several 4x4 trucks. ..Lada niva diesel. Jeep Cherokee turbo diesel .series 2a diesel , Mercedes 240gd.
I always liked the discoveries. So finally we looked at one , this one. My wife liked it and here it is. My main attraction was the manual.

She likes stick as well.....


Maybe I was a bit to eager.. starter did not work somewhat rusty under driver seat and in one rear wheel well. frame looks ok.

A push start did the trick, a bit slow to get back to idle. Brakes seemed to work.. money was handed over and the next day a friend drove me over, filled up 5 gallon gas, so as to make the 100 mile trip back home without stopping..
Nice adventure, it ran good for a 30 year old vehicle, did not overheating and did not stall.. from first to second made some noise but a double clutch took care of that. Clutch is really deep but did not slip.

Applied for antique title, to many cars to inspect .

My 96 Manual has 290K miles. (Looks kind of like yours!)

 

[joeblack5]

It sure does, do you still have a paint code on your car?
It is kind of greenish with a little bit of metallic .
Thanks , johan

I think mine is called Epson Green.
