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 :/

    • Clinton and I spoke to Alan Heaphy at length last year at the Bathurst 1000 about the Gibson GTR's that he had at the track and the restoration work that his company was involved with. He has a number of people working for him who were part of Gibson Motorsport when these cars were being built and raced. What impressed me the most was the amount of first hand knowledge and information that he and his team have about the Gibson GTR's and their meticulous attention to detail in the restoration and maintenance of these cars.
    • When you track RPM vs time it's clean, unlike the OEM one, even with filtering there are ripples. Means no random misfires or triggering issues at higher RPM, especially if you have big lift cams and a noisier valve train due to heavier springs.
    • Brake Fluid testers are cheap and readily available....eg https://www.supercheapauto.com.au/p/endeavour-brake-fluid-tester-rechargeable/SPO9539349.html
    • Cleaner signal so timing is more accurate at all rpm also found it to start more on first rotation but could also be I've nailed prime and crank fuel. For under $400 and 30mins of your time, its a good solution especially once the optical sensor does start to play up you won't notice it until in higher rpm and it heat soaks.
    • On a 400hp RB, what benefits other than "it's not 30+ years old" are you seeing from the NZ Wiring Kit trigger setup? If it were me going to change triggering, my belief would be to go for a crank trigger to remove the issues caused by what people claim is belt stretch etc, but that's from my understanding a much larger issue for super high power, rather than those in the 400hp and below club.
