my oil pump stop working today , is it easy to repair  with the engine in the car , any ideas is helpfull.

nope its basically impossible to replace with the engine in the car, you need to take the sump off to take the oil pump off. And you need to remove the flywheel to remove the sump. And you need to remove the clutch to remove the flywheel. And you need to remove the gearbox to remove the clutch....you can see how this story goes.

And since you are doing all that, and presumably you had 0 oil pressure, then you might as well do the bearings at the same time. And get your crank checked to make sure its still straight.

Its a huge job, like Duncan said..

Also if your oil pump failed - I'd suggest you inspect the condition of the bottom end and head (bearings etc) because almost definately you will find that the motor has sustained damage.

I shut my engine off immediately as soon as I lost oil pressure (within 2 seconds) but it still sustained damage to the bearings.

My engine and clutch are coming out next week, so it might be an idea to do the oil pump aswell. Whats a oil pump replacement worth? I thought NISMO ones were pretty damm expensive, but whats a worthwhile replacement without spending heaps??

N1 pump is only ~500 trade from Nissan (its been a while)

Its a fairly big job thats the downside

If you're doing oilpump, you're not far away from pulling the whole bottom end out and at least inspecting it. At least that way you're getting an idea of how the motor is going (bearing wise etc) and can adjust your plans to suit.

Nope, once everything is disconnected it is very easy from there, just a standard engine crane works fine as long as the car isn't too high off the ground on stands in the first place. Takes a lot of work to get ready to lift the engine out tho.

And your other option is to take the engine out the bottom of the car....undo the tailshaft, front drive shafts and drop the front subframe, out comes whole engine and gearbox. Just lift the car off the engine using an engine hoist.

Yeah we just did it in the garage, although I supose it would be even easier with a hoist......good luck....not sure which is easier, we put it in over the top last time and was pretty easy but we've done it a few times now....

I've heard/read that taking the engine out the bottom is much easier/simpler but I'll need to take the engine out in the home garage.

THanks for the reply Duncan

We took the engine out of mine out the top, and will replace from the top as well

Just disconnect the gearbox first and it's not too hard ;)

Thanks Duncan, thanks JimiH!

Hi Lucien. No problems, but now I'm replacing those sills that were crushed I'm having the entire car painted. This means I'll be keeping her a long time and I'm keen to take the engine out and replace every hose I can get my fat little fingers on. I'll renew the pumps and will change the timing belt, even though it looks like it has already been done.

It doesn't HAVE to come out, just thought it might be easier to do so. I'd like to repaint the engine covers and the inlet plenum too. *shrugs shoulders* Just thinking out loud when the opportunity arose ;)

Did you end up doing your drive shafts Mark ?

I agree with Lucien, do all the gaskets while the engine's out.

I pulled mine apart and did headgasket, all other gaskets, new pumps etc ... definitely worth doing for peace of mind :rofl:

How do you know that your oil pump stopped working?

Maybe it's the oil pressure gauge that isn't working?

Maybe it's the oil pressure sensor that isn't working?

:rofl:

Yep, had the boots replaced. The Repco universal ones won't work. The OEM boot (passenger side iirc) has two 'scalloped' cuts to fit around other components. I ended up asking Paul (two.06l) to do it for me as he has the right tools. One of the Repco boots split when putting it on, the other one ended up becoming an inner boot. Moral of the story is use parts from Mr Nissan.

Re gaskets etc.: I still don't trust the engine. The paint is peeling off the inlet plenum and the ECU wasn't screwed in correctly. I haven't found any signs of an EBC but I'm big on preventative maintenance before I go asking the engine for more power. I'm planning on doing exactly what you've done JiMiH. Did you DIY?

(sorry about the hijack guys)

      I guess one thing that might be wrong is the manifold pressure.  It is a constant -5.9 and never moves even under 100% throttle and load.  I would expect it to atleast go to 0 correct?  It's doing this with the OEM MAP as well as the ECU vacuum sensor. When trying to tune the base map under load the crosshairs only climb vertically with RPM, but always in the -5.9 column.

      AHHHH gotchaa, I'll do that once I am home again. I tried doing the harness with the multimeter but it seems the car needed a jump, there was no power when it was in the "ON" position. Not sure if I should use car battery jump starter or if its because the stuff that has been disconnect the car just does send power.

      As far as I can tell I have everything properly set in the Haltech software for engine size, injector data, all sensors seem to be reporting proper numbers.  If I change any injector details it doesnt run right.    Changing the base map is having the biggest change in response, im not sure how people are saying it doesnt really matter.  I'm guessing under normal conditions the ECU is able to self adjust and keep everything smooth.   Right now my best performance is happening by lowering the base map just enough to where the ECU us doing short term cut of about 45% to reach the target Lambda of 14.7.  That way when I start putting load on it still has high enough fuel map to not be so lean.  After 2500 rpm I raised the base map to what would be really rich at no load, but still helps with the lean spots on load.  I figure I don't have much reason to be above 2500rpm with no load.  When watching other videos it seems their target is reached much faster than mine.  Mine takes forever to adjust and reach the target. My next few days will be spent making sure timing is good, it was running fine before doing the ECU and DBW swap, but want to verify.  I'll also probably swap in the new injectors I bought as well as a walbro 255 pump.

      It would be different if the sealant hadn't started to peel up with gaps in the glue about ~6cm and bigger in some areas. I would much prefer not having to do the work take them off the car . However, the filler the owner put in the roof rack mount cavities has shrunk and begun to crack on the rail delete panels. I cant trust that to hold off moisture ingress especially where I live. Not only that but I have faded paint on as well as on either side of these panels, so they would need to come off to give the roofline a proper respray. My goal is to get in there and put a healthy amount of epoxy instead of panel filler/bog and potentially skin with carbon fiber. I have 2 spare rolls from an old motorcycle fairing project from a few years back and I think it'd be a nice touch on a black stag.  I've seen some threads where people replace their roof rack delete with a welded in sheet metal part. But has anyone re-worked the roof rails themselves? It seems like there is a lot of volume there to add in some threads and maybe a keyway for a quick(er) release roof rack system. Not afraid to mill something out if I have to. It would be cool to have a cross bar only setup. That way I can keep the sleek roofline that would accept a couple bolts to gain back that extra utility  3D print some snazzy covers to hide the threaded section to be thorough and keep things covered when not using the rack.

      Probably not. A workshop grade scantool is my go to for proper Consult interrogation. Any workshop grade tool should do it. Just go to a workshop.
