Hello everyone,

 

I'm recently opened my rb25de Neo valve cover (Exhaust side) and I noticed that the wall where the rocker cover gasket sits in was oxidized and fell off.

my question is can this be fixed?

or should i just swap it with the RB20de neo cover and are the rb25de neo and rb20de neo covers the same?

First things first... What. The. Living. f**k? How? Just how? Have you been parking it in an acid bath?

2nd. Yes, maybe a talented welder could build that back up and then machine it flat. But....you would only do that for a vintage car where getting a replacement is zero chance.

3rd. Yes, it is almost certain that all the Neo (turbo/NA/20/25) covers should fit.

That was my reaction to bro "First things first... What. The. Living. f**k? How? Just how? Have you been parking it in an acid bath?" 

I still cant believe what I saw this afternoon.

This car has been sitting for approx. 10 years. I pulled it out of a ER34 which I bought for $250

So I was thinking to take the engine apart and check if its still good if yes I was thinking of rebuilding it and swapping it with my RB20de Neo. also down the road I was thinking to convert it into a Rb25de-t.

someone went already to buy some parts of this car and they left the bonnet open I think for years so I hope not to see any other surprises down the teardown.

the car came with the auto Trans, eco, wiring, cluster the RB25de neo

I'm pretty speechless. I don't know if you're attempting to rescue that car..

or you have another car, and you're using the one pictured as a parts car and salvaging as many as possible things from it...


Either way this is going to be an uphill battle, I am suprised there is a Skyline (or two?) in Surname!

Lol are you speachless to bro? 

 

I will keep you guys updated during the teardown. 

I also noticed this on my cams is it normal?

 

Are you worried about the grinding marks on the shaft or some wear marks on the lobes? The grinding marks may or may not be factory. It is common for there to be some grinding marks along the casting flashes on those parts of the cam. Yours look like they were fairly aggressively done, but there's nothing to suggest that it's not as-factory. They might have been touched up by someone who thought that further removing casting flashes would improve the cams (when it really wouldn't).

Have a google image search for RB25 cams (and also google for RB20 and RB26 cams) and look at the variation is what can be seen there.

Nah man i have another r34 and i am trying to use the orange skyline as a parts car and salvage as many as possible. I opened the rb25de neo engine yesterday and there are a lot of suprises in the engine. Will upload the videos in a minute. 

 

Yes there were alot of skylines like 10years back in suriname. But maintenance is hard for the people here so the cars end up dead or scrapped. I have a college who has a r34 sedan with a rb25det neo engine and nismo cluster etc.

    • All I can say Duncan is good luck and I hope that Neil did not run any E85 in Cheryl. I have recently experienced the full spectrum of fuel tank issues in my R33's that had been caused by E85 and contaminated fuel. When you take the cover off the top of the tank and have a look inside you will get an understanding of how easy it will be. Best case situation is clean fuel with minimal contamination. My GTR was like this and it was a very simple operation to just grab the fuel pump carrier bracket and slide it up and out of the tank. My three GTS_T's had different levels of fuel contamination that was probably caused by E85 in the fuel.  In the worst case all of the metal components in the tank had rusted to the point where there were pieces of rusted metal swirling around in the tank. This required the removal of the exhaust, the tailshaft, the complete rear cradle and the fuel tank. The components in the tank were that rusted that it took days to get the fuel pump carrier and the mounting brackets out of the tank. When the tank was finally cleaned, everything inside the tank had to be replaced. With the tank all back together I could then reinstall it in the car along with everything else that had to come out. Good luck and I hope that you find a clean tank.    
    • It is a two door. It is black and also still has the OEM wheels and stereo. Exact model would be KR_R32RGFEL_SS According to GTR-Registry.com is a 2 Door Coupe; RB20DE; 2WD no HICAS; MT.F5; (11L) Projector Headlamps and Fog Lights; (12_) Electronic Active Full Auto Air Con (Climate Control); (13-14SS) V Selection -- Which seems to be accurate description of my variant. Will try to upload a few pictures soon. The OEM wheels look like the below image. Image is taken from the goo-net-exchange website.

    • Welcome Gabriel. At least your car has a glorious RB and not the shitty CA18. As MBS206 mentioned all the good bits can be added later. Two doors or four?
    • And half of them have been converted to turbos.
