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 :/

    • This looks great! Awesome to have the 5 speed with an LSD in this. The Recaro's look like SR2's or SR3's. It's a shame they've been retrimmed as they would have looked sweet in their original colours. I think I'd want my agent to be a little more up front and informative too. I've never imported but I reckon it would make me a little nervous, so the more info the better.
    • Thanks for doing that Duncan! Makes you a good person in my books. We don't get kangaroos or wombats here. But we have bats and it's similar. AFAIK it's often the mums with a baby attached that get hit because they drop lower when starting from a tree. If you hit an animal, check on it. https://www.ifaw.org/au/resources/wildlife-rescue-app An app to get the closest wildlife rescue contact.
    • My dream is also to have a proper hoist, but I don't think it will ever happen. My quickjack is probably as close as I'll ever get, it really is very good though. 
    • Yeah we keep on in the dailies, it is pretty poor how many animals get hit and the driver leaves without checking....have saved a couple of little ones over the years. Bit of a gruesome job though, pouches generally need to be cut open because they are so tight and often the joey doesn't realise mum is gone so they are still locked onto the teat. I checked the modules in front of the DS wheel where an oil cooler should go.... There is the radar unit - that can go for race use) One of the 2 HX water pumps, the silver cylinder. That needs to be kept but might be able to be relocated But the bad news, the big computer mounted vertically in front of the wheel (blocking any potential air exit) is the electric steering computer. That is required until/unless i do a hydraulic steering conversion, and in CAD based modern car design it is not like I can just pop a big unit like that somewhere else (plus the loom would be too short anywhere else too). So, the passenger side is OK to clear out (just use a smaller washer reservoir, potentially elsewhere), but the DS no beuno
    • Well, all the best with the new camry It was interesting to hear about the UK process, it is generally a lot more streamlined here with a shipping agent looking after all the import side (noting the exact final price can still be a surprise.....) and I've used a few different brokers on the japan (or US) side, and never had any trouble with any of them....luck of the draw I guess. You mentioned you didn't get the auction sheet (understandable since you bought it from a dealer, not auction), but I always try and get hold of that because they are pretty thorough. I've imported 2x R grade vehicles over the years and both were fine, repairs in Japan are pretty thorough compared to here in Oz.
