Vtec fell off

[rawr]

I used the search button but came up with way too many queries and I'm kind of in a rush to get to uni.

My vtec fell off, literally. It won't kick in. It may kick in sometimes but then it falls out again.
I was getting a wierd buzzing sound the other day when I gave it a hit and now realise it would have been the smaller cams not being able to spin at that rpm.

Does anyone know the reason/s for this and how to fix it?
My first thought is the solenoid, but could there be any other reason and how would you fix the solenoid? I just changed the sparkies and am going for a routine oil + oil filter change later today.

pretty sure its the Oil dre.. running low perhaps?
"sexc car" btw

[rawr]

was that you? LMAO you have girly writing! why didn't you say hi!

Could be the oil, I'll get back to this thread after I do the oil

[ECU-MAN]

you need to check your oil pressure ( while driving and engaging VTEC ) to see what pressure yuou have and if the needle is fluctuating

best to have someone help you so you dont crash your car while looking at the oil guage

do you have a dent on your sump ?

[rawr]

Cars pretty high so i don't think I could have dented it I'll take a look at it. Thanks for the advice. If the oil pressure is low? what does that mean?

Listen to ECU-MAN...

[ECU-MAN]

ECU won't let you engage vtec if the oil pressure isn't up to scratch because good pressure is needed to physically engage the system.

If pressure is good check for continuity on the vtec solonoid line from the ECU to the plug.

yes it will,

the ECU does not know what the oil pressure is, and only when VTEC kicks in ( if the car has a VTP ) it will look for oil pressure to determin if the VTS has engaed. If that part failed you will get code 22.

If the ECU cannot see the VTEC solenoid it will give code 21

with low oil pressure Vtec will still engage but soon drop out.

. If the oil pressure is low? what does that mean?

then you may need a new oil pump, or very low on oil.

[rawr]

and that is why you are the green block gangster. Bout to change the oil + filter. Using penrite(semi -synthetic) 10w 50 with OEM filter... is that ok guys?

maybe a super hot summer or track oil but please dont use that stuff for a daily dude. Use 10-30w
