Tapping Noise, R33 Gtst

Recommended Posts

Hey guys, Hope you can help me out with this.

When i start my car, the engine runs fine, but if i start driving before its totally warmed up (ie. reading half on temp gauge), it runs smoothly but makes and annoying kind of tapping noise from the engine. I dont drive it hard with the engine cold and this has only recently occurred. I am avoiding driving incase i do some damage to it. Once the eingine is hot the sound goes away...

Has anyone had this probem? and if so is there anything i should do about this before something bad happens?

Cheers,

Andrew

Thanks for the links mate. My searching skills obviously not upto scratch.

Oil pressure and levels are fine..

Pretty sure that its the exhaust gasket problem discussed in one of the links you provided. The most plausable reason for what i'm experiencing.

Cheers,

Andrew

Hi there, just thought I'd share my 2 cents worth. I too have a tapping sound that comes from my car, and the majority of you have said that it is exhaust related. I've been wondering about mine, having fears that it was the lifters, cams and oil etc etc, but it has turned out to be the exhaust afterall. I have a broken manifold stud...so yeh, chances are that the light tapping does infact come from exhaust leaks most of the time.

I've been told that these are not too harmful to the motor if they are at the manifold like mine, however they can make the turbo run much hotter due to the air it's sucking in. Can lead to wheel meltdown apparantly so I'm keeping mine on stock boost till I get it fixed. The bad thing is that the gap will open further and further thru time increasing the chances of turbine damage...si it's worthwhile getting it looked at early.

Normally in my case you'd replace ALL studs, and get the manifold faced for a perfect new fit :)

    • People still have Skylines? I thought they're non-existent now. 
    • Harness update time have had great fun and learnt so much already so far with this project. I started off making both the ignition and injector sub harnesses in the hope any mistakes i made here aren't as hard to undo and learn from as the main harness.  A cool comparison of the old harness using presumably TXL wire and the new which is using Tezel. Also opted to use DTM plugs to keep the whole setup as neat and tidy as possible and tucked the wiring under the coil bracket to try and keep it all from sticking out too much. Although the injector harness, I'm not overly happy with as I'm still using the rubber boots that are supplied with the type of plugs it just looks ugly and sticks out like a sore thumb with the white identifiers so a slight redesign may be done.   Then it was main harness time and most importantly trying to route it nice and away from the heat it will use the OEM heater hose routing which is no longer present to keep the harness up high and secure. it's amazing how much smaller this harness is able to be compared to the old one. plugged everything into the emtron and with the help of the tuner again attempted to start it up and instantly fired up and running smoothly on all 6 which was a big shock to myself. So still some routing and adjusting to be done for the final fit up and installing a knock sensor harness plug which is in the post all has gone surprisingly well.     The old harness for shits and giggles.
    • They do that at random every now and then, with almost no detectable cause. Mine has done it a couple of times (over 25 years!!). Never worked out why.
    • I don't post on here and have been lurking for some time now. Many of the topics have helped me out more times than i can count. I was racing yesterday (11/9) and blew a front right CV shaft. I have spares so I popped a new one in. A thread i read previously said to check the engine mounts if you blow a front CV. Upon inspection, the front right mount was completely separated from the upper plate. This discovery saved me time and money, because i would have blown another CV if i went back out. Just wanted to thank you guys and wish everyone luck with with their builds. (Now if we could only come up with a solution for my power steering belt flying off after hitting the rev limiter, lol)
    • Either way he still need those style of spacer to go into the manifold because the photo he currently has is not going to work
