noticed the other day that my rb25det has a little oil in the coolant, not enough to change the color of the coolant but i can notice it when its in a puddle on the ground.

It seems to have lost abit of power from when i bought ( 2weeks ago), it does have a coolant leak from the block ( not was whats the parts called but ordered a replace from nissan, 3 weeks away, also ordered a coolant temp sensor as it wont start first time without pumping the accelerator.

Car doesnt show no signs of over heating, just a slight bit of oil in coolant and loss of power?

I wouldn't drive it if I were you.

This problem gets worse, not better and it's only a matter of time before the reverse (much worse) happens, if it hasn't already, ie. water in oil.

Sounds like a track between water jacket and oil gallery.

huh

if coolant is leaking from the gasket out your head running down the side of you block how is oil going to find its way into you radiator

yeah after re-reading it a few time i finally saw my errors :merli: brain was faster than my typing

haha, cause coolant already lives in the radiator bud.

I think you meant oil in the radiator which can track between galleries, cylinders and externally.....depending on whether it's a head gasket issue, cracked head, warped head, corroded head, etc.

i had a similar failure in my mx83 cressida. had a wee bit of oil in the coolant, then eventually the metal ring in the gasket around piston 6 distorted letting water in to the combustion chamber.

needless to say piston 6 was looking nice and clean after its steam bath :/

replacing head gasket isnt that hard, if you are doing it yourself make sure you take pictures of everything you take off so you have reference to put it back together :/

    • Ok thanks..that was my second question if i can somehow bypass this even with Nistune(that is all i have right now...aparat from stock ECU. So with some aftemarket it can by "bypassed" or make it work?  I know there is Link or Haltech (mainly used). We have ECUmaster here so i will gather some info about it.
    • Yes. You will need to get the original boost sensor and wire it in. That is.... if you plan to use a stock ECU - even a Nistuned ECU. The Nissan ECU will not operate correctly without it connected. And yes, it will do annoying stuff like you are experiencing. You will almost certainly be better off with some aftermarket ECU, than trying to hunt down rare sensors.
    • Ok so ABS/TCS is "not" the problem. Yeah i know now about the ABS with Nistune(i told that to the Nistune guy) but iam not 100% why or why i dont have ABS. ABS cube is in the engine (always has been) but i had braked couple of times rly hard and brakes just locked and scream. Does all Skylines have ABS cube? That boost sensor https://www.sau.com.au/forums/topic/367633-wtb-r34-gtt-turbo-pressure-sensor-pics-inside/ Is this it? I need to ask but i have a picture of engine bay and i do not see that (100% is not in that place) If i do not have this the car can do what mine is?(cutting around 4000 rpm) Here is the pic of my engine bay(only one i have) BUT i think i dont have that cuz loom was used from my RB20DE NEO and i know (obviously) that it does not have boost control or any wire to that...) so maybe that is the problem? (i dont know for 100% if that car where the engine is from had that)...but i dont have the loom from that
