I recently completed a motor build and lately I have been burning a lot of oil when getting into VTEC. The car is a 2000 Civic Si. The car only burns oil when in VTEC. Could this just be due to aggressive cams or a timing issue?

Sounds to me like something didn't seal properly when you rebuilt the engine...
Or it could just be that VTEC is too Earth-shattering for your oil and your oil is spontaneously combusting out of pure amazement :lol:
I am reading good compression in all 4 cylinders so I am wondering if simply I am running too rich..
Perhaps another tune would be in order?
I also noticed that if I do not hit vtec for a few days and hit that magical 5500 rpm limit, that I will burn more than when I hit it every day...
You didnt break in the engine properly. 1500 miles of easy driving is what is recommended. Medium revs with varying load inputs is what is recommended. The smoking and oil burning will only get worse. Why arent you consulting Superhonda.com or one of those forums??
Hondas always burn tons of oil at high rpm operation... what kind of oil consumption are you getting? Can you see the cars behind you? :lol:
I have been around a few honda N/A builds and all of them burn some oil. Its a honda dont worry about it. :lol:
you and the poster above you are both 'tardedQuote:

what are the signs that youre notising that make you say youre burning oil......... are you smelling it, are you seeing it, whats going on???
if you just built the motor you really shouldnt be hitting VTEC for at least a month or two.... thats like buying a brand new clucth and peeling out.... cause all sorts of problems
I made it about 3 days, my friend did it the first hour he had his clutch done...Quote:

Why would anyone be nice on a newly built engine? It makes sense to drive it nice for the first day just to make sure there is nothing wrong, but after that first day why would you baby it?
Your car learns how you drive and if you put on 5k miles of never going over 4k, how do you think the motor is going to react when it sees it the first time?
Ive been around a few Honda builds, the builders are people who know what they are doing. Every single one of the builds that I have seen they have burned a bit of oil, not a ton of it but they have all burned some.
Unless you are sending clouds of smoke out your tail pipe I wouldnt worry about it. If you are loosing a quart of oil every week, I would start to worry.
the fact is when you put a brand new part (esp pistons and what not) into a used engine and immediatly just start beating the s%& out of it your bound to get uneven wear... endless problems. Yes i understand its extremely tempting to gun it right after a newly HP proven add on, but it should still be "broken in". Stuff is going to expand and shrink the first couple of times of use and will eventually fit in "right". Im not saying it was done wrong, but im simply saying i think it wouldve been start to take it easy for a bit.
O BTW S2000 are nice cars, the only honda i would think about purchasing, helping a buddy turbo his next week.
If you are asking those questions, then you don't know sqwat about building engines. There is a difference between race cars and street cars. Do honda engines smoke excessively from the factory? H3LL NO!! Then why should they smoke after a correct rebuild and break-in? They shouldn't. No street car should be smoking after a rebuild unless its a 4G63 engine because they run rich and just puff oil particles forever. The builders may know what they are doing but if they are screeming the life out of a freshly rebuilt engine, they are idiots.Quote:

I had more space to work with in a 1973 Austin Mini. If I were considering a S2000, I would buy any generation Audi TT turbo over it.Quote:

Anyways you do not drive the ^**^ out of a freshly rebuilt car.
