i have an ls vtec.... *** of late my vtec is not working. i hvae oil i changed ecus and selinoids. i even hooked up a push button tom my vtec selinoid and pressed it when vtec should hit. it didnt.... when i hit where v tec should be i blow allot of white smoke out of my exahust. my car does not smoke untill 5800 and then it blows allot of it what could this be someone help i need my vtec back

 

White smoke = blown head gasket. This link should solve ALL your ?'s https://honda-tech.com/zerothread?id=1812135

 

well im not throwing any codes so my oil pressure would not have anything to do with it and if it was a head gasket wouldnt it blow smoke all the time not just at high rpms?

 

A blown HG can be big and the engine won't run worth a lick, or small and smoke a little bit, even intermittently.

Just because you haven't destroyed your engine running it with no oil until the oil light comes on, doesn't mean you have enough oil.

 

i always check my oil before i start my car... head gasket would explain the smoke but what explains the no Vtec???? plz help

 

Figure it out. Start with the wiring and VTEC solenoid.

 

i have changed selinoids and have even wired them up to a push button and vtec still did not hit if i hook the selinoid to a 12v it should hit no matter what right? would that mean that the selinoids that i put in are junk? i only used used ones how do u know if the selinoid is good before u put it in?

You have bigger problems than a lack of VTEC.
If the wiring and VTEC solenoids are o.k., the problem is oil pressure or mechanical. Locking VTEC pins missing or incorrectly installed, missing o-ring or dowel under #3 cam cap perhaps.

 

thanx for the ideas... i hope its not major

 

Does your oil pan have any dents in it? I've seen vtec not cross over do to the pan being dented and the pick up is not sucking up enough oil......just a thought

 

i have a brand new moroso 5.5 quart

 

im just going to get a new head gasket and new rings... that way i can get my head machined... i have a eagle stroker kit but i didnt put it in. it was in when i bought the car... if i dont know what the exact part # is, how do i get the correct rings???? help would be apreciated thanx for all the help so far

 

how are you running oil to your head? you using the golden eagle kit or a homemade "T" and line?

im sure you did. But, you did plug the vtec oil hole in the head right?

 

i had vtec before.... i did not just build a motor and vtec didnt work it worked before

You use whatever size rings your pistons are. Are you asking about bearings?

better be findin me some numbers before we pull my b16 and tosss that biatch in my BOOGER

 

Maybe you shouldn't be putting an engine together if you don't have the means to measure the piston and rings.

 

maybe u should read before posting ... the motor is already built if u are going to leave smart *** comments atleast have your facts right before wasting my time
