HELP!!! Rebuild RB26 advice needed!!!

[justinfox]

Hi all,

My car is in pristine condition, engine is running great, but since tracking it for the past few months there has been an oil leak which is getting worse and worse.

Today on track, after the 1st session (hot day Eastern Creek) I stopped in pit lane and damn oil was dripping out from all over the place. There was a massive puddle at the end. It wasn't so bad each session after that, but still, oil is leaking everywhere.

My mechanic cannot fix the problem as he cannot reach it. It's on the other side of the engine (not the turbo side) and he says:

A) It would be a waste of my cash to do an engine rebuild now as my engine is in such great condition.

B) Maybe I should wait until I blow it up!!!!??? LOL. It's a catch 22 as you can see... engine is going hard, car is perfect but there's an oil leak no one can get to without lifting the engine out, which means I should just do a rebuild?

Any advice would be appreciated. I want to make this a bullet proof track car! Any suggestions on price for a rebuild would be ghreat (what budget should I set aside?). I already have new injectors and head gasket ready to go on, new radiator too and HKS 2530 turbos, all ready to go on... so maybe I should just do the rebuild, install turbos and go all out for stronger internals? Pistons? Conrods? Is $10k enough for all this?! Or am I looking at MORE?!

ANy help appreciated. Thanks in advance guys. Loving the GT-R more and more and always knew I'd have to look into a rebuild at some stage. I'm up for the commitment!

just pull it an dfix the leak

why would you rebuild it???

just rix the leak normally is only about 500 bux to rip the engine out and put it back pluss whatever it cost to fix the leak

[[[d a n n y]]]

did u change your turbos yet?

fix it while your putting your new turbos in.

or if u sold your new turbos

then just lift the engine up and fix it.

easy as that.

my rebuild cost me 10.3 G

Well mechanic says it's on the other side of the turbos. And the engine does not need to come out if you are installing turbos.

I will see if I can just fix the leak without a full rebuild. Report back soon.

you can replace the turbos without lifting the engine, but it is very fiddly and may drive the mechanic mad, so it is prefferable to just lift the engine and replace them

so if i were u i would just have the engine lifted while getting the tubos changed, and get the oil leak fixed at the same time.

forget about rebuilding if its a simple oil leak, what for!???

plus u need to change the turbos(lift engine) anyway so even better.

[fatz]

only takes 3 hours to remove the turbos from a engine in the engine bay

4 hours to put back in... dont know why you would have to remove the engine to do so

[KamikazeR33]

it all depends on how long u want the engine to last... eventually its going to blow. how long determines many factors

as a question... couldnt u just hoist the car up and get to the leak from below?

btw ive just paid for my engine build which is a 25/30 combo - $5400 inc labour - includes new pistons, linished and treated rods, complete head work with all new valve springs, guides etc

[fatz]

yea my gtr rebuilt was done for about 5k as well

and thats a pretty seriouse rebuild

[Morgs]

Pull the motor and fix the thing like Pete said. Then blow it up. Then rebuild it.

Or buy a 2nd RB26 and rebuild that, and pull your pristine RB26 out and sell it once its built. Thats what I'm doing

[Parag0n]

morgs is an RB26 Abuser

[RB30-POWER]

LOL, not to sure what the fuss is about.

If you have a leak, it must be fixed!

Just get it fixed or your motor will fail due to oil starvation, especially if its leaking as bad as you say it is.

I don't know why you would rebuild it for the sake of it, unless you were planning on some major mods or power increase. (Or you are loaded with cash, in which case it shouldnt worry you getting a oil leak fixed)

[The Dan]

Is the oil leak on the same side of the engine as the turbos or the opposite side?

anyway, whichever the case...your mechanic is an idiot. I can get to anything on those engines without removing anything. It's just a matter of having the right tools.

There really isn't many possibilities for oil leaks on the turbo side except for return lines and feed lines. That's assuming is't engine oil.

If it's on the other side then it'll probably be the oil pressure sender leaking or the oil filter not on correctly(tight). Those couple of things asside from the sump are really the only places that oil can come from the side. Front and back are a different story. PM me for more details or if you want some solutions.

[Jengi]

There should be no problem fixing the leak?

I don't see why the mechanic is unable to reach the leak? The engine should not need to be hoisted either.

Source where it's coming from and fix it asap, otherwise you do a lot of damage in the process of doing trackdays while it slowly leaks.
