dammit...

i know this is the technical section, but geesus i hate maths.

100 bottles of R28 wynns petrol cleaner is R2800.00, not R280.00

so its actually 10 times more expensive, but gives 10 times more mileage from a tank...

so its THE SAME DIFFERENCE!!!!

It's actually R2800 for the 100 bottles. But if the car DID infact run on Wynns rather than fuel, calculating that it adds 2km per litre to a full tank of fuel (which is a dilution of 500ml into 50 litres):

mileage on Wynns = 2km/l * 50 / 0.5 = 200km per litre

So, out of a full tank, you will get..... 10,000kms!!! WOOOOHOOOO!!!
10,000km for R2800, that's 28c per kilometer!

check it - take plug out, hold against engine (WITH PLIERS!!)
check spark - bigger gap gives bigger spark (up to a point)
too big i've heard that the "flame will get blown out", which i think is BS, but just regurgitating what ive heard - flame away
too small, too cold = carbon

bigger spark = faster than a red s13!
You know, a lot of people have alot to say, lets stop talking, come and beat my slow red sx with my small gap with my spark blown out.....!

I am not be the fastest at all but Freddy should be able to tell you that I am not slow at all....with my small gap and blown out spark......!

My setup works for me, if your mind tells you it can't, suck it up like a big boy and let the truth be.....

ok i'm now ready to piss in anyones porridge at the moment.

this weekend i had the head in pieces, cams out, i replaced the noisy lifters with not so noisy ones. you can hear which are the noisy ones with a nice long screwdriver shoved in your ear!!! or a mechanic's stethascope!!!

i checked out the coils, i fixed an oil leak, i generally sorted the head out. i did forget to regap the plugs, and they looked a little bigger than normal.

and yesterday afternoon the car was going like an animal!!! at all boosts, and all rpm's, and all temperatures!!!

this morning is spent 45 mins in heavy traffic and after that the damn !@!!!!@$#^#^#$%&*%(^&*)^%#$%!@! sx woldn't rev past 3600rpm without doing splutter-fart-no power-black fuel out the exhaust-backfiring like an R1 rifle-thingy!!!

it seems like its only when its hot.

here's a pic of my open cylinder head.

Image

this is how clean things are after 15000km's of driving almost everyday! i am so proud, but at the moment we aren't friends!!!

Seems the sx pissed in your porrige :lol: it sounds to me like a leak in the head gasket, see if she is using water, if she is, retorque the head or the gasket has gone, that was my problem a wile back....other than that it might be your knock sensor thats buggerd...but thats unlikely

its the recommended ngk plugs, 'cept i think they the "r" type. think it has a resistor in it. at the time of service, a sunday, thats all i could find.

the engine isn't consuming any water, and there is no mayo in the oil cap. so i think the headgasket is fine. its new 15000km's old, and the car hasn't been overboosted, or overheated at all!

hmmmm

it sounds to me like your plugs are bombing out man...

my personal recommendation (if you running stock boost) get some BCPR6-ES - stick that in there and check what it does in traffic.

thats what i got, except that i remember it ending in 11, which means it comes with a gap of 1.1mm.

i just couldn't remember that code - but that r in the middle is what i was referring to.

i'm hoping its not a coil problem that only rears when the coils get hot!

are you sure about that plug name?

cuz the only ones i remember ending in 11 is the platinum ones - and they defo need gapping smaller

i dont think they were platinum cos a set cost less than 100 bucks, in fact i think it was about R45.

but i gapped them to 0.8mm anyway!

i will get them out again, right down the code, check the gaps, and drive around with my coil cover off for a while!!!
