I Think My Rb25 Is Dead

[R33_Rob]

hey fellas

recently i have heard this weird sound between 1600 - 1800 rpm. It is a quick tapping sound and kinda sounds like a cricket or something. I took it back to the dealer today and he says that its probably a "gudging bolt". Im not quite sure if thats how its spelt, but its the bolt that holds the piston to the conrod. I guess its kinda hard for you guys to make a judgement without hearing the sound but any help would be greatly appreciated.

By the way its an RB25DE hence non turbo

gudeon pin i think he meant to say...Yes it does hold the conrod to the piston, but i doubt he could guess that straight from hearing it and be 100% correct. Best to get her comp checked and leakdown test etc, then if no problem seems to come about, then outsource someone pop her open and check her out. If theres a problem, may pay to look into a RB25DET replacement or rebuilding her for a turbo. Up to you.

gudeon pin

transplant a RB25DET?

[R33_Rob]

R32 Abuser, what do you mean by comp tested and leakdown tested? And when you say etc is there any other test in specific that you are refferring to? Im willing to try everything to fix this. THis is last f**king thing i need to go wrong with my car. Are all skylines unreliable or is mine just a lemon.

Does the ticking noise get quicker as the revs go up?

Could be something as simple as a warped exhaust manifold...or some kind of exhaust leak between the engine and the manifold.

[R33_Rob]

it gets marginally quicker as the revs go up. Oh and yes it was the Gudeon pin which i was talking about.

Wheres the best place/cheapest to have this looked at. Since im at bulimba i dont wonna drive the car too far considering the state that its in. Anyone know of anywhere in the bulimba/hawthorn/balmoral/ surrounding areas. Im currently working with tuff toys (who i orginally purchased the car from) but they dont really wonna know about it until the engine breaks

bump

still in need of help

could just be pinging? get some guys who know engines to have a listen.

[R33_Rob]

I dont know if its pinging, it sounds more like a knock

I'd suggest big end bearing. Drop the oil and look for sparkles which will be the bearing coming apart.

[R33_Rob]

YES. i changed the oil and there was the slightest bit of grit in some parts of the oil. Like it was finer than a grain of sand but i could still feel it. Whats the next step? Bearing trouble means i need a new engine doesnt it?

[NISZILA]

If its the bearing, you don't need a new engine, but you will need to take your engine out to fix it. Since you have to take it out anyway, just put an RB25DET in its place

[R33_Rob]

I went and got a second opinion today. But the noise had stopped. Kinda dissapointing, an engine replacement would give me a proper reason to get a turbo.

Piston slap? Hey I thought I'd throw that in
