my car has bad picked up a pinging when it goes past 4500RPM

I use BP ultimate in it, i have had it to a local workshop who had it all day and said it will have to go back when they can figure out what is causing it

They believe if anything it may be an aftermarket 02 sensor that isn't working with the standard ECU, anyone got any other ideas what may be happening as it started it out of the blue one day while driving to work.

nah i haven't done anything to it yet. As far as i was concerned when i bought it, it was all stock standard except the HKS airfilter now i find out it has a aftermarket turbo dump and oxygen sensor. they checked all the mixtures and said that they were all correct

could be a bad batch of fuel. try some good octane boost like nulon pro strength. if that solves it then wait and see if it still does it on the next tank of fuel. if it still does it then get it looked it, if it doesn't come back even after a few more tanks of fuel then it was just a bad batch. and make sure you don't put too much octane boost in as it can actually lower the octane.

mate of mine is a mechanic and he had the nulon rep come through work and he was asking him about the octane boost. the rep had an octane tester with him so they did some tests. at 50% strength it went by only about 2ron, at full strenght it went up by 6ron, and at double strength it dropped by 4ron.

      What should I do next to hold the head on

      By Gareth87 · Posted

      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.

      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
