And how often should you replace them?

You replace it when you flush your vtec fluid... Which should roughly be 100k

sleepy are you using the honda oem vtec fluid or megnaoil's full synthetic high milage vtec fluid?

does it still "kick" in?

 
Rep Power: 172

just the conventional fluid for my vtec think i need a new reservoir tho :/

 
Rep Power: 211

That's exactly why i don't use the vee tak...too much maintenance involved. The synthetic stuff is like $50 a quart.

I use the oem vtec fluid. It's pretty cheap at my local honda stealership since I have a friend that works there.

It's still expensive as hell. That's why I don't go over 4k rpms.

Drain and fill, not flush. Especially not with synthetic.
Remember to clean the VTEC solenoid's filter after. People always forget to clean it.

Muffler bearings are also highly overlooked. How do you guys constantly forget those?

 
Rep Power: 211

You have a point. They should actually be changed at the same time, as on most models with VTEC, the muffler bearings are lubricated with the same fluid, and therefore increase the frequency at which you should replace the vtec filter.

The only pulley that normally needs replacing on an engine is the harmonic balancer. The harmonic balancer usually has a rubber component to isolate vibrations and this can break down over time. I would think this would be examined when the timing belt is done and replaced if necessary. Since the one for the Civic is in $40 range I could see where some may do it with the timing belt just to be safe.

can't believe you all forgot about halogen fluid!

 
Rep Power: 292

I think because most of us switched to Xenon fluid

stumbled upon some 50/50 vtec fluid ended up warping all my rotor bearings :/ stick with the synthetic! youll regret it if you dont

 
Rep Power: 512

aw, dude.. 50/50 vtec fluid is crap.. You shoulda searched it before buying it. There are a buncha threads on how shitty the 50/50 stuff is..

Actually, it's not terrible if you upgraded from vtec to vtech though, but I'd still stick to full synthetic

 
Rep Power: 294

Agree, I always replaced mine with the timing belt.

next belt change im also replacing the cam pulley because it was completely rusted last time i saw it.

i noticed my grandma had v tech the other day, im like gram! what is this crap? i dont even have v tech....but she had someone come to her house and install it where as to me it sounds like a hard diy.... anyone done this care to input for my sake?

 
Rep Power: 211

Don't even bother trying unless you're a certified vtec installer...sh*t's hard man!

 
Rep Power: 292

just make sure you set your vtech to 2.4ghz, or you wont get the best response

 
Rep Power: 172

tried the install before checking back with you guys :/ broke the cam stretcher clean in half, off to honda tomorrow to pic up a new one for 4k....hooray for spending money p.s. the t66 sucked soooooo much air!

 
Rep Power: 512

Dude... Search next time.. T66 doesn't play well with the D17.. Install a Gallo 24 and all your worries will go away. It's the same price and works SOOOO much better under the hood..

you mean the auto tensioner?

what about AC and alternator pulleys or camshaft pulley? they dont ever need replacing?

 
Rep Power: 512

Alt and ps pulleys are solid metal dude... I mean, if you wanna just spend money, by all means.. You can send that cash my way if you so desire, as well...

 
Rep Power: 353

dude, where the hell did you get your gallo 24?!?!? i been looking for one for the past year without any luck....

 
Rep Power: 211

I didn't know pizza places made motors...

 
Rep Power: 512

Quit searching for the Gallo 12 and you'll prolly find one no problem, you silly ****..

thinking about a w16 convert in the 7th gen now, anyone shed some light?

 
Rep Power: 292

W16 would never fit inside the hood, unless you carve into the firewall.
and it doesnt have vtak, so wiring would be a mess.

 
Rep Power: 210

When an auto tensioner is replaced it is usually not because the pulley is worn but because the spring that supplies the tension is weakened. In the case of the timing belt it is done before the spring weakens and the timing belts slips.

There is nothing in the A/C, alternator or camshaft pulley to wear so no need to replace.

 
Rep Power: 193

The only w16 that will fit in the civics engine bay without cutting into the firewall is the 8.0l from the veyron. You just need a stage 2 clutch. Otherwise its a direct swap
