Just a quick questian Will say lowerd springs from a commodore ute fit a sedan as a guy on ebay has them for sale they look identical to me?
i have another questian i took my engine cover off my vy ecotec v6, then i unscrew the allenkey head bolts from the top of the throttle body removed the top cover an gasket rubber to find it is black as crude oil an just down right filithy,i have noticed ther a a number of 11 or 12mm head bolts zig zaging along from front to rear is that how i remove it to carby clean it ? thanks guys
#1, the springs may very well fit, but id say they would be different strengths and therefore would be firmer or softer and sit at a different height.... ect
and #2, the lid just unbolts via the allen screws and then yes you can spray carbi cleaner into it. one suggestion tho, is that you pull the spark plugs or you will get compression lock from the fluid sitting in the head/valves. i learnt the hard way and nearly burnt out a starter motor. another suggestion would be just to undo the intake pipe (unplug the maf) and spray into the TB with the engine running and bring up the revs while spraying or it will stall.
i did it that way to my wifes VX. cleaned up the plenum real nice.
edit, just re read your post, if its real gungy and oily in your plenum perhaps its time to look at a rebuild? that mess is usually caused by a lack of compression creating blowby and thats what your PCV breathes. and that means your engine is also breathing it.
Ok well iam quite keen on removing it an cleaning it up properly,an its only done 115.000Kms dosent blow smoke i look after it, well i do my best but thanks heaps im going to clean it now,an ok i wont order the ute springs(things id do if i didnt have this site an u guys to get advice from.)
also what about hsv V8 springs will they work in ym Vy accliam?
what sort of "mod chip" did you get? was it a memcal or one of those resistor things that piggybacks a sensor?
i got +15hp high preformance chip that plugs into the IAT sensor advances the timing by 2 deg,apparently (cough) B.S! live and learn
ha. sorry . they do work. but! its definately cheating. all they do is trick the ECM into thinking its getting something its not. so dumps more fuel and advances the timing. i had one in my VN, but i had big pipes, bit TB, port work, a fuel pressure reg ect, so the little resistor helped by advancing my timing and pushing more fuel. so for me, it worked well.
Yea i dont have the cia yet or the extractors,plus it was a ebay chip from the Uk Plus i dont think its really worth it i saw dyno data on a car with it in an same car without,lost 6kw with it in ? but like u said diffrent strokes for diffrent folks.lol
