Missing / Turbo....

[justin911]

hey ppls

having some issues again... :~(

when im driving round these days sometimes after like 4000 or so rpm i will kinda like loose engine power for a second when shes on like 7 or more psi...

Is it that kinda the same as missing... ? it doesnt realy cough or splutter... its just as if the engine turns off for like 1 second...

should i be doing the hole coil pack trick for this problem.. ?

also i dont no if its related... but my turbo seems to be heaps louder now... its bit odd...

it kinda makes this wierd loud angry spooling kinda noise...

it doesnt seem to make any ticking or metal on metal noises though...

?

getting real pissed off real quick with all these constant car issus

thanks heaps

oh yeah... i also put in new spark plugs recenly.. but the problem started a couple of weeks after that...

however repco told me 'BCPR6ES - 8' spark plugs and 'BCPR6ES' plugs

were both .8mm ?? so i just got the 'bcpr6es ' ones... perhaps this isnt correct ??

I thought the standard gap was 1.1mm?

The 6 bit is the heat rating, I beleive. (how far the inside conductor sticks out the plug)

I have the same thing, and there is a huge thread about inspecting and repairing hairline cracks in your coilpacks. The theory is, the spark it exiting the crack in the pack, rather than going to your spark plugs.

New plugs are gapped correctly, so the spark has to jump further, which causes the cracks in the packs to be more of a hinderance. If you gap the plugs down (dodgy fix), then the spark is more likely to jump that smaller distance, rather than jump through the crack.

Best to fix your coilpacks, leave a good gap on the plugs (better burn).

I think I have a broken exhaust gasket... I get a ticking sound from it. I can hear it quite obviously when I pull up next to a wall. Might want to sus that area? Or check the other gaskets on the turbo?

cool thanks for that with the ticking/gasket noise though .. do u here it when ur just idling ?? mines kinda just a loud turbo kinda noise.. i dont no if its leaking anywhere thought because it doesnt seem to be loosing boost at all..

i put the older spark plugs back in just now.. i also had a look at the coil packs with a torch.. i couldnt realy see any cracks or anything that looked wierd on the rubber bit or the plastic parts.. also that yellow see through stuff at the back of them looked alright to..

Hi mate,

I had the exact same problem after changing my coils and plugs to ngk iriway irridiums. Just double check all the clamps on your inlet hose and make sure they're nice and tight, and that they'res no cracks/splits in the rubber joins. One of the clamps wasnt done up and was blowing open above 9psi or so, causing the car to basically die for about a sec on even moderate acceleration, driving like an old man the car was ok though. Also had the 'angry spooling noise' it sounded wiked tho lol pity its gone.

Also be careful not to get too worried about a ticking noise, it could just be your injectors - in which case its normal. They seem really loud if you have the car in and enclosed space, or if you're running the engine with the bonnet open.

If your running above 12 psi that 0.8 gap is good, below that a 1.1 gap is normal have a look here for more info.

yeah i chucked my old ones back in last week.. fixed her up real good. The new 'pre gapped' ones were crap.. 3 of them were 1.1, 2 were .8 and the other one was like .10

thanks for the help tho
