i was giving it beans chasing my mates in a 200sx and a cossie keeping up rearly well (up to 140 cough*)and everything seemed normal untill i stoped for a piss somwhere and when i was cranking it over it sounds like one or more cylenders hant got any compression

once running it drives normaly and power fells about right and it dont smaoke all the time apart from my usualy smokey turbo problem on over run

once cranked up it ticks over normaly and drives normaly

water and oil are ok too

i have a innovate wideband guage installed in my car and wad reading 10.5:1 AFR at 140 mph so was quite rich to say the least!

does it look like i have melted the headgasket between 2 cylenders?

Can't help you about your problem mate but isn't this a brand new build!?

Surely you shouldnt have these type of problems already!

Rab

Perhaps you should adjust your topic title to something along the lines of "i think i fuked the Zetec turbo on top speed run on the PRIVATE TEST TRACK NEAR ME HOUSE"

mrviper

yep

i think its just the decomp plate given up

acrralites from burtons is the answer to why i was using a decomp and never spending a penny there again

it wasnt deting because i made shure it wouldnt

i will whip the head off tomorrow and see

and runnig 13 psi

bit strange how it runs mormally tho ?

U sound like ur being a little bit of a hypocondriac...... The starter motor itself can cause this..... If it runs fine, u must have compression, but do a test.... Mine's been past 140 loooooooads of times without a hitch touch wood.

yeah, my motto is if it ain't broke don't fix it!

& funny noises don't count, turn the music up loader!

mrviper

im whiping the head off tomorrow

hopfully this aint going to be a melted piston thread

i cant see it rearly as i was running it safe ie retarded and ful loads of juice at 10.5:1 afr

Rick

why? check the compression first!
