sledgehammer

Thanks. I change the hose first and see if that fixed it.

Hi, found a oil leak under my car. It seems to be the oil cooler. Should I replace the whole cooler or just fix the hoses? It seems to be not an very easy job so I probably ask a mechanic. The GTT is clean without any mods. Oil cooler is genuine too. Anyone had this before? Thanks!

Ok then I‘m relieved. Thanks ?

When checking the RB25DET Neo of my R34 GTT I noticed that there are two empty holes for bolts and I have no idea if that‘s normal (see image). Is something missing there? I do have some issues, probably a boost leak or something. But I don‘t know if it‘s linked to this. The holes are located above the heat shield of the turbo. Thank you!

I‘m driving a almost stock R34 GTT with the Neo RB25DET. Is it normal that I can‘t hear that typical „psssh“ sound after boosting/taking my foot off the gas? Boost pressure seems fine though and I can hear the turbo noise. Also no flutter. Could it be a BOV leak?

Thank you for your help, really appreciate it. Now I know better where to look for. I tighten it up, clean the maf and see if that already fixed the problem. I read that an exhaust leak also could leak to bad smell and bad performance.

Uh, I guess I found the reason for the boost leak. Bolt was almost out completely. Turbocharger to manifold. The other bolts were lose too. I hope the gasket is fine.

Here a photo of the turbo. Something bad that happened when I tried to remove a porous hose. The very small pipe of the breather pipe broke off (see photos). So thats something to fix now somehow.

Turbo seems fine. No scraping, shaft play minimal up and down, not horziontal. In and out a very very little. Feels like 0.5 mm. But again, I can't make it scrap by hand. My guess is that the whining noise is coming from the bearing or some boost leak.

Even better if I don't have to take out the whole turbo. I'm gonna post the result here once I'm done.

Then that's the first thing I'm gonna do. Just to be sure. The boost noise is there since I bought the car a year ago. So I believe it's just the bearings or a leak. If hitting, then it would be long dead I guess. First time turbo removal for me, that's gonna be fun. After that: Check all connections, other leaks, sensor, catalyst, change fuel filter and maybe fuel pump.

Thanks, I'm gonna have a look that everything is connected. Could it also be caused by a boost leak? The turbo makes a high pitched sound when boosted but I'm not sure wether it's the old ceramic turbo or a leak. Also on my list of things to check. How about the fuel pump?

Thanks all. What could cause the car running lean? I may use the search function for that

Hi all, recently I changed my spark plugs. Went from heat range 6 to 7 as the previous ones were white (running too hot). Not sure why though, because the engine is stock. A days of driving later I noticed a bad smell coming from outside when the window is opened. Only while I drive over 60kmh. If the window is closed there is no smell at all, also not from the A/C. So my guess is that it's either because of the ignition or spark plugs.. or the catalyst. Or maybe both? From what I know is that defect spark plugs can damage the cat. On the other hand the car is running fine, no misfire, etc. Only that bad smell. Anyone had this before? Could it also be something else? Thanks!

Thanks for the replies. Stock intake. Someone told me that it is the sound of the nylon turbo fan, when it's about to say "goodbye". He had the same issue with an 2JZ. A bit worried about it.
