Yes ARP studs are reusable. Rb's have a water/oil heat exchanger located bellow the oil filter. Sometimes these can fail and allow water into the oil system. Just thinking out loud and something you could check before you go ripping the head off.

Thank you for the reply mate I didn't kno that......any idea on a price to replace that? The radiator had pressure aswell wasn't bubbling jus popped when removing the cap not sure if it's normal for this motor and or turbo motors..

 

cheers 

Was the motor warm, as the radiator will pressurise normally. Idealy I'd do a compression test. Tk test, and if there both ok then I'd just pull the water lines off the heat exchanger, loop them together and get the rb30 oil filter stud and remove the heat exchanger all together

http://wbtools.com.au/products/automotive-equipment/tee-kay-head-check-combustion-leak-detector/ is a tk test, basically you use the pump on it to Pump some air off the top of the radiator and if the fluid the air goes threw changes colour it means there's combustion gases in the cooling system, with the most likley cause being a blown head gasket. However if you have oil and water mixing with a negative tk test and even compression it's most likly not from a blown head gasket

Ahk lol yea I get what u mean I've done it to a few cars before jus never heard of it being called a tk test lol in saying that I've been away from cars for a fair few yrs due to loss of license ..only got it back like a month ago...thanx for the help mate..pretty sure I have one of those test kits laying around my shed somewhere..lent my compression tester out n never saw it again so I'll invest in a new one of those aswell, I'm doubting it being blown head gasket only bcoz of how good the car ran most seem to struggle under load etc that I've dealt with anyhow..hoping it's that heat exchanger thing I've got the timing belt off but I'll put it back together n get rid of the heat exchanger n c how it goes after tests.

 

so I'll need to run a rb30 oil filter with this adaptor once I remove the heat exchange? 

When you unbolt the heat exchanger you will see a metal fitting in the block. If you unscrew it a rb30 stud screws in, can be bought from Nissan for like $10 then a oil filter will screw straight to.the block. However it's best to use a z418 with an internal bypass valve after that as the z145 doesn't have the internal bypass as it's built into the heat exchanger

K so i put it all back together today filled radiator with jus water it started perfectly fine and nothing out of the ordonary drove it out the back yard n reversed it back to the carport area... opened up the radiator cap and it had heaps of pressure in t and really frothy.... turned it straight off n dropped a few F bombs lol head gasket is deffs gone the exhaust had shit coming out clear fluid no smoke that i could see... already priced head gasket n gates racing belt kit through kudos motorsport ill jus have to bite the bullet n do it 

Yea owell shit happens lol it wasnt very hot had the thermos running from the moment i started it as they run of a toggle switch...and it pushed out a heap of frothy water when i took the cap off n was a decent amount of pressure behind it...its a shame but at leaste i kno what the issue is and i can fix it all myself...

thanx a bunch for the input guys look forward to being part of the skyline community ??

    • You just need to remove the compressor housing, not the entire turbo. I would not be drilling and tapping anything with the housing still on anyways. 
    • So, I put my boat on a boat. First of all, I'm going to come out and say it. Why is Tasmania not considered a holy goal, an apex that all road-legal modified cars go to, to experience? This place is an absolute wonderland of titanic proportions. If people are already getting club runs for once in a lifetime 30 person cruises to Tassy then I've never seemed to see it. It is like someone replaced the entire place with an idyllic wonderland for cars, and all of the people living there with paid actors who are kind, humble, and friendly. Dear god. After doing a lap of almost all of the place I've found that it's a great way to find out all of the little things that the car isn't doing quite right and a great way to figure it all out. All in all, I drove for 4 hours a day for a week and nothing broke. I didn't even need to open the engine bay. This is by all means a great success, but it has left me with a list of things to potentially address. I also now have a 3D printed wheel fitment tool which annoyingly hasn't got any threads in it to actually assemble it. I might be able to tape it together to check the sizing I actually want to use, but it'll likely involving pulling the shocks out to properly measure travel at least at the front, and probably raise the car while I'm at it, at least in the rear. I scraped on quite a few things and I'm not sure how else to go about it. I was taking anything with a bump at what felt like 89 degree angles. And address those 10 other tasks. And wash the car. God damn it is dirty. And somehow, the weather was perfect the entire time - And because I was on the top of Mt Wellington it turns out it was very much about to freeze up there. I did something I typically never do and took some photos up there in what must have been -10 and the foggy felt like suspended ice, rather than mere fog. If you own a car in Australia, you owe it to yourself to do it.
    • Damn that was hilarious, and a bit embarrassing for skylines in general 😂 vintage car life ey. That R33 really stomped. Pretty entertaining stuff
    • Hi, I have a r32 gtr transmission. Does any of you guys have an idea how much power it will hold with the billet center plate and stock gearset? At what power level and use did yours brake with or without billet plate? Thanks, Oystein Lovik
    • Saw this replica police car based on a Mitsubishi Starion XX parked next to a 'police box' (it's literally a box) in Hirohata, Himeji City in Hyogo prefecture the other day. It's owned by Morii-san who is a local Mitsubishi Starion enthusiast. According to a local radio station blog post, he always wanted to make a police car himself based on ones he saw in his favourite Manga comics.  As it's illegal to modify a car to look like a police car and drive on the road, Morii-san tried many times to get permission from Aboshi police station headquarters nearby. They refused initially by after they got tired of that they granted him permission. However, the car can only be displayed on private property and obviously can't be registered as long as the police livery is present. The car was completed at a cost of 1.5 million yen (US$ 10,000) in addition to the car cost. A location was chosen outside Hirohata Police box where the car can easily been seen from the street. Morii-san has two other Starion road cars, both widebody GSR-VRs.
