Yeah did a oil change Saturday. Had done 7000 so will change at 5000 now religiously it disappeared at idle after the change and is only 2800-3200 on no6 under gentle acceleration in second? Rattle rattle - gone? No noise with 6 coil pack disconnected! Weird.

how loud is it? 
 
not sure if you can use an oil flush to get the gunk out... they arent too bad to clean apart from having to get them out. there are also a couple different varieties on our engines. look the same externally but different sizing internally

Haven't pulled the cam cover but goes away with no 6 H.t. Disconnected? So I would assume a cam lifter follower issue? Seeing as its on the exhaust side?

Can only pick up the rattle in 2nd gear under mild acceleration?

 

 

 

 

U should have a lisren to my engine, rattles at idle (suspect the turbo may well be dying lol) about 3k its got a ting ting noise and at the top it sounds like a big ol straight six on heat ? 

Wouldnt be lifter, weather u disconect the coil or not it the lifters gonna do its job. However, if u disconnect the coil and it goes away ur taking the combustion away from that cyclinder. So id be looking for a leaky manifold around nunber 6 or anything in general todo with number 6

Yeah i panicked at first thinking ouch turbo, bearings, piston slap, gudgeon pin, big end knock etc. but can fully pinpoint the sound to no6 rear exhaust cam cover at only that tiny rev range. Will sus it out better on the w/end? Might need a real mechanic! Would assume tig welding it won't help!

Will suss it out better Saturday. Thanks for the advice guys, I appreciate it. It will give me a better starting point for trouble shooting. Never owned or worked on a car with a turbo or the cam shaft/s in the right spot except the last 8 months. Show us your v8's. She's running absolutely trick except for that! My wife and jack recond the noise is in my head! What noise! (perhaps the loony bin would be a better fix?) done all the turbo/dump pipe studs gaskets etc. So will check the manifold.
when you drive something often enough you can hear noises before anyone else or before it becomes a problem

Spent 3 months of weekends when I got it fixing rattles blips blurts knocks and bumps! Only drive her on w/ends. The captain always goes down with his ship. Then emerges with less money and More power!

I remember having issues with the escort (when I was 18) flushed and cleaned everything new radiator, heater core, plugs points gaskets leads jets etc. I was putting a new head gasket on when dad came out and wiggled the no.4 piston with his hand. Think I found your problem mate! Sell it now.

    • 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
