hey guys, my car GTT R34 is having constant popping or backfire which im not sure whether this is exactly called backfire. The only reason why im not sure is cuz im so definite that the sound is coming from the front pipe area and not exactly from the end of the muffler.

Regardless, as i constantly have this sound every gear change throughout the day, would it cause any issues later in the long-run? Such as molds in the pipe to affect performance in a bad way?

Thanks in advanced guys

Popping from near the front pipe? Does it sound like their is an exhaust leak? Check your gaskets etc.

Well im pretty sure the BOV is the cause of the pops, but i just have no idea why the sound is coming more like near the cat area rather than at the end of the muffler...would gasket leaks or exhaust leaks result in pops also btw? thanks for the reply

start the car in the morning, then get someone to put there hand over the tailpipe to block it while you listen in the general area of the "popping" - this should elt you hear any leaks in the exhaust.

Backfires and popping screwed my new cat a while back, shattered the rear brick and it shifted in the housing causing a huge restriction and performance loss.

    • I can see between the water jacket and cyl 3 there wasn't a hard line of combustion gas. It certainly appears that the issue is coming from there. Yes, checked the tension. All at 100ft lbs where I set them 5 years ago. These blocks can crack but generally when they have been over bored. Mine is only 0.5mm oversize at 89.5mm. They break between cylinders around the 91mm mark. No sign of that with mine. My gut feeling is the head gasket lifted a while back when the studs stretched and i bandaided it by retorquing the studs. It's finally let go.
    • My Nismo 1.5 churps a bit on reverse turns when cold, but besides that feels like a stock diff.
    • Yes, but, I paid cash and I'm pretty sure the receipt was in the bin 10 minutes after I got home Note to self, keep all receipts
    • Bunnings would have just handed you your money back on that one!
    • So, version 4 intake is on its way I was looking at these a while ago but at around $200 or more it was a little pricey for something that might not work, but, I had it in my watch list, but, I got a message saying it was on special, and I had a code thingie to use, it eventually came in at $120 delivered, so BAM, BUY NOW.....LOL I'll need to have a look when it arrives but I feel it will "look" better than what I currently have, as it comes with a PCV fitting, so I will be able to get rid of the alloy pipe that goes to the throttle body with the PCV fitting  Well, that's what the voices in my head are telling me  Oh, and this happened today Yeap, it was a Trojan, and it was cheap, so I headed back to the hardware store and actually spent a little bit more on a heavy duty,  one that was actually recommended by a plumber mate, a Cyclone one with a fibreglass handle that is actually rated for clay The broken shovel will eventually be "modified" into a short handle shovel
