^ Pretty much

Thats why I originally didnt say 'this will definetly be it' but it is most likely one of those things. I suppose if you wanted to test the heat exchanger you could remove the coolant lines, link them together and then run the car and see if the problem gets worse, or if you get oil leakage out of the coolant ports in the heat exchanger. Just let the thing warm up easy

Otherwise if its head gasket/head related then the only option is to pull the head off.

Well, if you want to look at it that way, then yeah, it is an expensive way to diagnose a problem. But I tend toward the expectation that people on here who ask these questions need a mechanic to do the work, so they will then take it to a mech with the "oil in water" story. Whether the head gasket gets replaced or not would then depend on what the mechanic finds.

But I take your point.

there is tests you can perform to determine if the hg is blown or not whilst the motor is intact,taking the(factory) hg off usually destroys it and it maybe harrd to pick up where it blew(thats if it blew at all)

its just the way it is

Over the course of a weeks driving does it use much coolant?

Not the same car, but my Commodore had similar issues after I replaced the radiator and thermostat, new fluid etc.

I swore I'd done the head gasket, as after a few days there was little bits of oily crap on the rubber of the radiator cap. Then I checked the overflow, and it was in there too.

It was using around 100ml of coolant a day.

I found a heater hose that was a bit loose, and then dumped the coolant and replaced it. Its been fine ever since! The only thing I could think of was either the new radiator had a bit of crap in it, and the fresh coolant might have dislodged some buildup from the engine somewhere.

Check the overflow bottle to see if its got the same stuff in it

(to op 2nd answer above )not time to panic yet strongly suggest you get the engine tested before you start tearing the motor down and then having to work out which TAB you can rob to pay for it :-)

Oil in water and combustion gases in water are two separate things though. I don't think there's a "test" that will tell you that your oil in water problem is definitely HG or not.

      RB25DE NEO with Haltech ECU

      By Haggerty · Posted

      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.

      spot the stagea

      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.

      R32 GTS (RB20DE) Injectors Replacement

      By GabsReDeal · Posted

      In my head it does make sense to be a fuel problem since that is what I touched when cleaning the system. When I was testing with the fuel pressure gauge, the pressure was constantly 2.5 bar with the FPR vacuum removed. When stalling, the pressure was going up to 3.0 bar (which is how it should be on ignition).

      ECUtalk pages don't mention they support the ABS computer (consult port has more than one CAN), so you might just need a different scan tool. But, I would expect ABS is a different light to the brake warning/handbrake light, do you see an ABS light come on for a few seconds when you turn the key from ACC to IGN? But since you said: I'd have a look at the ABS sensors in the rear hubs to make sure they are not damaged, disconnected etc.
