Hi Guys

So I'm taking my car to my mechanic for a freshen up and to ready the engine for some proper boost (skyline r33 RB25DET)

I want to sort out all oil leak issues - will obviously be doing the rocker cover gaskets,half moons etc...

What else should I replace while there? Anyone know what other common leaks the RB25DET has?

Yep.

Common spot is the camshaft seals. You would be mental to pay someone to replace just those without also doing belt, tensioners, water pump.

An oil leak makes no difference to how much power an engine can make.

What is involved in this freshen up?

How will it stop it going bang?

Did my 100k service about 10k ago. Well the camcover gaskets are leaking pretty bad(as in all RB's) so its kinda obscuring what else could be leaking as well., hence be wanting to know what could be leaking :)

Freshen up will include,walbro gs342, new breather hoses, transmission cooler and fixing up of all oil leaks (4th March) and obviously usual 5000km service(oil and filter change)

Will be installing new radiator,stage 2 shift kit, new radiator hoses, highflow turbo and 550's on my trip after that and then ready to tune (5th May)

you would be wise to check whether they actually replaced the cam seals or not. cam seals = front of motor, where the CAS bolts onto. mine leaked at 160k because they werent' changed at the 100k service.

cam cover seals are easy to do yourself. cam seals are a lot more work, timing belt off etc.

      RB25DE NEO with Haltech ECU

      By Haggerty · Posted

      I seem to the be only person that is using a Haltech 2500 on an NA motor, I've installed a Bosch DBW throttle body to the OEM intake manifold and am having problems maintaining AFR even with the wideband o2.  It will run extremely rich at idle and up to redline, but under load it will go extremely lean in the 20s and i'm essentially having to rev it over 4k and feather the clutch to get it up to speed.  I've read a few other threads of about the butterfly, it seems removing the vacuum to it is supposed to have it remain open, i've noticed no difference under 4k with the vacuum line to it plugged.  I'm hoping someone here has had luck using the NA manifold with Haltech, and if they happen to have a tune for it.

      Could it really happen......

      I don't know any details, but I really wouldn't be surprised if they do it as a LHD only version, at least initially.

      What should I do next to hold the head on

      By Gareth87 · Posted

      Thanks for the replies everyone. Definitely a coolant push. Oil catch can is empty and always has been. As the engine is out now I'll be having a good look over things. I do have some detonation on the piston tops from a trigger issue back about 5 years ago. I felt it and shut off then bought a new ecu and changed the trigger. Never been an issue since. It never hurt the power, its made almost 80hp more since that incident but I will pull the bearing caps to take a look. If the bearings are damaged I will do a bottom end refresh. Head is being re conditioned at the moment and the block will be cleaned and checked to ensure it's flat. I'll go with a kameari gasket and see how it ends up. The other thing I'm not super keen on is the cylinder colours. I suspect this is from the inlet manifold. The plan will be to put it back together, retune and then stick a plazmaman billet inlet on it and retune. I'm happy with the power, if it makes a little more, then great, but I would rather just make everything more efficient at this stage.

      Maybe they'll look to do a bunch of presales to help inject some cash fast for their financial issues...

      Does it also misfire equally when revving?   Josh is very correct in what you should do. The coilpack harness wiring loom itself is a known problem due to its age and the number of heat cycles it has gone through. Throwing parts at a vehicle to diagnose the issue isn't a smart or good way to do it. Secondly, you may have a bad coil pack, you pop replacements in, they fix that issue, but messing with the harness breaks it, so the issue persists. So now you think "well it wasn't the coil packs" and have to continue chasing your tail, potentially swapping back in your shit coil packs and returning the good ones (yes, I've seen people do this because 'it wasn't the problem' and they want to save money). And suddenly, you've got two issues with the same symptoms...   Diagnose, don't use the spare parts shotgun.
