Blown head gasket ?

Hey guys n gals, so I've just purchased my first non holden car at the ripe age of 27...got a r33 turbo has a few decent mods ..exhaust, coilovers turbo timer, fmic few other bits n peices, ran perfectly fine but noticed the oil is milky so it's time to remove the head n replace the gasket n timing belt... any tips n tricks that can be thrown my way would be muchly appreciated I've done many head gaskets before jus never worked on a skyline before, only Rv motor I've touched was my old vl Calais turbo I had about 6 yrs ago...cheers

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

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 ??

      ECU sees many times the speed than speedo does (R34 swap)

      By Kapr · Posted

      The car/ECU will have all the sensor that it needs and expect to have. I think i do not have to explain to you how the Link is way better specialy if you have swapped engine   I just do not want to deal with any "problems" cuz i have only Nistune which i learned is not that great and in my case cant even deal with that speed problem (Link can) And of course it will be way more easier to tune and diagnose and safe. And for the ECU/speed problem...i dont know.

      Per Mark Roberts of Sonictune: Mark Robert Author At this time, no. No ETA either 2016-17 models. You will be able to purchase and install a 2018.5+ TCU though   TCU purchasing and pricing info! As we near the release of TCU tuning, I am going to answer some questions I get asked often.   What do I need for TCU tuning? At this time, you will need a 2018.5+ TCU to be able to tune. If you have a 2016-to early 2018, you will need to replace your TCU with the newer version. One good way to know if your TCU is good is if you have auto upshift in manual mode in 1st gear around 6500 rpms. If your manual 1st gear goes to 7k rpm and will hit the rev limiter unless you shift, you have the older TCU.   Why do I need to buy another ecu license/phone flash if I already have it on my ECU tune? The TCU is its own computer module. It is completely separate from the ECU. Because of this, you will be required to purchase a TCU license and, if your tuner has it, the phone flash license required to tune it via phone/bluetooth.   Do I need TCU tuning? TCU tuning is NOT required. However, the faster your setup, the more it will assist in track and dragy time consistency.   If I’m ECU tuned by (tuner A) can I get my TCU tuned by (Tuner ? Yes, since it’s a different module and a completely separate flash, you can have two different tuners. However, it is highly recommend that you have both tuned by the same tuner. For me, my TCU tuning will directly complement my ECU tuning style and features and running my ECU and another TCU or vice versa MIGHT cause some issues. At this time and for the foreseeable future, I will only be tuning my current ECU tuned customers TCUs.     I have a SYVECS AWD controller. Do I still need it? Yes! The AWD controllers main job is to control your AWD system. However, with TCU tuning, you will no longer need the auto-shift function as that will be done through the TCU. The AWD controller will still be very beneficial for racers looking to maximize traction on the launch.     Shift schedule changes: holding gears longer at lower pedal input as well as max shift rpm changes. Please note, the new ECU race rom coming out will address 90% of the shitty drivability issues these cars have through custom maps from myself and Racebox—as well as others I am sure.   Increase shift speeds: as seen in the videos I’ve been posting, the TCU shifts much faster once tuned.   Increased shift pressures: as also seen in the videos, much firmer full throttle shifts.

      The fancy pants red shock tower brace is finally incoming from MX5 Mania, getting it shipped from 'Merica has been a long and problematic process, and GWR, the 'Merican supplier will not ship directly to consumers outside of the US, Mania basically had to order a heap of them, the colour choice was silver, or red, and we all know anything red adds 5 killerwasps of dynotorques..... Whilst it does fit over a 2.5, and I've seen a few photos and videos of it being installed and fitting, google also says it might get real close to the FAB9 intake front runner, people in the US says it does fit with the FAB9 intake, except for one person who said it slightly touched.......so there is that.....LOL..... As it seems that I am the first in AU to have this combination of parts there's no local knowledge about fitment, so I'm just a willing guinea pig in this endeavour, I'll cross my fingers and toes and hope for the best In other news, I ordered stuff from China  on the same day I ordered the 23° silicone bend from Victoria, the stuff from China arrived a day ago, the 23° silicone bend is still travelling around Australia thanks to Australia Post, and "may" be here next week

      Very good news...I contacted Racebox about it last night. My car is a 2016 so remains to be seen if it is compatible, requires a TCU swap, or is impossible.
