need help on a 98 v6 motor

i have a 98 v6 vvti acc. motor, whoich i need to cheack the vvti rocker pistons if the engage......is there a way of doing that?????

ref:
i did put pres. in the vvti system but it leaks to the oil pump i think so that did n't work...
anyone let me know.......

dude, i have no idea what you're talking about.



anybody????

have you ever inspected your rockers and noticed that there are small pistons which engage the extra rocker that rides on the bigger lobe of the cam?????

I just found out that you need min...100psi of shop pressure in order for the pistons to engage the extra rocker.....if any one would like to know...
I know that Honda came out with several different designs of vvti what kind do you have honda99
:smokin:

first of all, Honda call it system VTEC, VVTI is treadmark of Toyota.

seems like thing that you call small piston is top end of valve stem.

solinoid engauges VTEC system on your engine by internal oil pressure. system engaugement is controlled by ECU and most of time it engauges at preset RPM's. on J30A1 (6gen AV6 engine) VTEC engauges at 3,500 RPM, but VTEC not always engauges at 3,500RPM, ECU will look at car speed, throttle position, atmospheric pressure, engine oil temperature to determine if it will let VTEC to work.
most of time it will engauge VTEC. there is only one reason for VTEC not to engauge under normal condition and that would be low oil level. any other problems with VTEC would indicated by check engine light.

my mistake, your right vtec... :eek7:
what other kinds of styles of vtec did Honda offer???

there is new system called i-VTEC, its avalable on K-series engines. K20 is on Civic Si and RSX. K24 is on Accord, CRV, TSX and Element.
with i-VTEC there is no preset VTEC engaugement, its vary throughout RPM range.

cool.....do you have any info on it.....??

do you know what the s2000 uses?????
:smokin:

you seems like hungry for engine information. :)
you should go to www.vtec.net to read on Honda engines.

BTW, S2000 has F20C engine with VTEC, but most likely next generation gonna get K22 with i-VTEC.

thanks..
I'm a Lexus tech...or i was now i'm at school getting my four year degree in automotive....and your right want to know as much as possible....if nothing else it makes my job easier..... :smokin:

VTEC kicks at 3500 on the V6's. Remove the air box and just listen for it. That'll tell ya if its working. :lol2:
