Well it turns out my leaking raditaor/hose is actually my welsh plugs in need of replacement.

A fairly cheap part that requires the manifolds removed to replace.

Thanks for the quick diagnosis Dan.

Any one in Brissy had these done?

Whats the labour time in pulling the Turbo off?

Half a day to get at them....half an hour to replace them...half a day to put every thing back.

You need to know if there is one in the rear of the block..cos if so you need to remove the engine or cut a hole in the firewall.....good luck

Most mechanics can do this. I had mine replace when my engine was built. It depends if you are going to replace them all or just the leaking one (best to replace ALL that you can GET too when replacing the leaking one).

Get some quotes and see if dan is available. If its around the head then most likely a head removal will be required = expensive and off the road.

Jay you should NEVER cut the firewall to change a welsh plug...

I'd just take everything apart yourself - and get a mobile mechanic to replace them. It's only nuts and bolts. Just time consuming to get them all off. Will save you hundreds.

And once you've done it once, it's much quicker the second, third, fourth, etc times :)

Hahaha!! I did that many years ago to my Mk2 Jaguar, Try removing a 3.8L straight six from a Mk2 by

yourself with minimal tools nil workshop gear and working in a dirt floored ex chicken coop :)

These days I would of course take out the engine and replace ALL the welchplugs.

It continues to surprise me that people are forever asking where they can get replacement parts

especially odd bits like welchplugs

Hint!! you are driving a NISSAN vehicle :O

Sigh! Try your nearest Nissan dealer you will need your VIN number

I think most of the bigger Nissan dealers now have the CD and someone who can find parts in it

I have found Nissan in Lutwich Rd Windsor...just down from the Royal Bris Hosp. to be very helpful and they will get stuff in from Japan if needed.

in the old Land Rover I just got the drill and drilled a hole in it and popped it out with a screwdriver, you should probobly not do this on the skyline as metal shavings could get in the engine, but if worst comes to worst.

Putting them back in was a bitch, make sure that you get areas very clean from rust and grease. I used some Extreme Temp gasket goo and applied to to both the Block and the Welsh Plug, waited till thay bacame "tacky" and then tapped them into place with a similar sized socket.

I am not saying that this is the correct way, but it worked for me and got me out of trouble (I was actually 200 Kms from home when this happened).

Chris

ps... Make sure that you get Brass Welsh Plugs.

      R34 gtt rb25det neo timing belt kit

      By drifter17a · Posted

      So now doing the change and first time dealing with rb so little nervous giving engine power and potential for screwing it up When you align all marks and then remove crank bolt, timing move little I assume you can put the bolt back in once you have removed the pully to get timing to where you want?   here is pic of my both intake and exchust cam aligned, depending on angle you look they seem to be either aligned or a half tooth or so out. Any thoughts? Should you angle your face and look at each mark that way as if looking straight rather than from above as it can be misleading   <a href="https://ibb.co/ZpnhcvbF"><img src="https://i.ibb.co/HfWrGR9b/IMG-4447.jpg" alt="IMG-4447" border="0"></a> <a href="https://ibb.co/4wm2wn4q"><img src="https://i.ibb.co/JWBqWwr1/IMG-4445.jpg" alt="IMG-4445" border="0"></a>   https://ibb.co/ZpnhcvbF https://ibb.co/4wm2wn4q

      braided lines for the turbos

      By sunsetR33 · Posted

      Thanks for the reply @GTSBoy Haven't really thought of that yet, but you are right. If the hose was damaged it should be absolutely pissing by now. I'll put some heat sleeve around it for good measure since I'm already removing the line anyway.  Maybe I'll put on some of the stock hardlines if I ever fully remove the turbos again. Maybe when T51R modding the compressor housings? Might be a fun mod on GT28s for that "fake single turbo" effect.

      Unpeeling the Orange

      By sunsetR33 · Posted

      Update 1: I did some work on the car already before finalizing this post and my "issues" list. I dropped the Tomei exhaust in favor of the HKS Hi Power Silent. Sounds nice and I can actually hear myself think now. Also gives me a realistic chance to legally drive without silencer inserts. A bit of cheating was necessary to still be able to mount the Top Secret style diffuser. Some malusage of washers and a bit of "convincing" toward the brackets and exhaust hanger seemed to do the trick. The shaky steering wheel has been resolved as various suspension components were worn, like sway bar bushings and link bars. Most notably the two steering tie rod ends. Had some trouble finding bushings because my sway bars are not OEM thickness, 23.x up front and 27 rear. But non adjustable, so no aftermarket I suppose. Maybe they are nismo units? Turbo oil drain hoses were definitely still the originals and are new now. Wasn't the cause of the turbo oil leak sadly. Currently removing the rear turbo because of it, I suspect the braided oil feed line is the culprit. This issue needs to be dealt with so I can work towards actually getting the turbo setup legal and inspected. Two new issues to add to the list as well. Rear Main seal is probably leaking. Time will show how bad it is, I don't really want to drop the gearbox right now just for the stupid seal. Could fix a few other things in one go once I do that. Front right driveshaft grease is going past the cv boot, so at some point I'll fix that too.

      RB20DE NEO smallbox clutch.

      By Kapr · Posted

      Ok so no 4cyl clutch... Yeah it is a factory manual. So if iam correct i need clutch and flywheel too? I can use something that suits something like R32 GTST?   EDIT: https://www.ebay.com/itm/224291042776 Is this ok?   EDIT2: i maybe forget to mention this(dk how important it is) but the trans will be behind RB25DET NEO(iam doing swap) It will be there for a little while. Iam planing to do bigbox or BMW tranny..

      You're probably right about that one. Thanks for your suggestions, I hope I don't need a new 3rd brake light. Although wiring issues might arguably be worse. Right now I'm in the midst of a turbo removal because of my oil leak, other problems are going to have to wait for now.
