anyone tried the intake manifold spacer? worth the $$ and the time?

i have the hondata intake manifold gasket on my D15b7
installed it when i put on the USDM D16z6 intake manifold
used Permatex Aviation gasket fluid on both sides for installation

i would say it has made a difference in eliminating the heat transfer from the head to the intake manifold
but have no idea how much performance was gained

Hey!

Ok got myself a daily driven D16A8, Meticulously looked after, genuine 200+K's always serviced with genuine honda liquids etc, Compression test gave me 205psi within all cynlinders.
But I can't figure out why my head, more specifically my valves/tappets are considerably loud? I have always adjusted the valves to the factory specs, torque specs are spot on, using the correct oil, but it is still loud enough to be heard and does not get quieter throughout the rev range. Is this normal for these engine? Cause i have a few mates with either a D16y8/y4/y1 etc and apart from the exhaust/intake noise, the engine itself is very subtle and quite smooth reving.
Also there is quite a vibration given of when i floor it here and there, more than usual compared to other D16's? My guess is my head is worn? or could it be something totally different?

Was hoping somone could shed some light?

P.S. Will try to record a vid so it should be more easier to understand.

Cheers!
Johnny.

maybe you're doing something wrong.

I've always noticed the valvetrain is quite noisy.

[JohnnyJohnJohn]

I really hope not, but then again I doubt it to be honest, been doing it for ages and been following the haynes manual etc. And the car drives like a dream, only noisy thats all =\

Are you rocking a D16A8 aswell? How's the engine like? really eager to fix this thing if it is broke...

I'm kinda thinking it sounds more like an oldschool type car//

[Bludger]

so what correct oil are you using?

[JohnnyJohnJohn]

Well since I've owned it I've been using FEO 10w30 for a long period of time, so has the previous owner(as i was told), a few months back I figured I'd try Penrite 5w-40 (HPR-5 Semi-Syn) for reasons such as the weather getting hotter, quicker warmups from cold starts and overall quieting down the noisy valvetrain and my car actually runs smoother aswell, good improvments and also not burning any oil.

I figured after summer passes or whenever the weather gets colder ill try penrite 5w-30 since hpr-5 works so well, in my opinion anyway?

my neighbor just bought an EG5 with D16a8 in it - at first the valvetrain was really loud and the car ran like crap
it had 235km city k's on the clock and was in pretty rough shape when we got it

i changed the oil + filter to Honda OEM FEO 10w30 with Honda OEM Blue filter + generic magnetic sump bolt
flushed the radiator and put in Honda OEM Blue coolant
and cleaned out the IACV, FITV, TB and calibrated the TPS
also adjusted the tappets/valve lash to correct specs
and replaced the crappy ebay pod filter with a Fujita unit
cleaned and painted the valve cover (not that it really effects performance)
removed any unnecessary wiring and did a clean + cable tuck
cleaned out the distributor and cleaned all the earth cable contact points

now the car runs MUCH MUCH better - but the valvetrain is still a tad noisy

I've done nearly everything you've mentioned and yea gotta agree that that valve-train is quite loud, wanted to know if there's anything I could possibly do to the head?

[TheSaint]

have you adjusted the valve lash/tappets?

[~Sp33~]

I just swapped it out for a DOHC ZC, which is pretty much the same. I had the d16a8 for 5 years though. It's a nice engine, torquey enough for a civic with decent pull at the top.

I wouldn't worry about the valve noise if you've adjusted the tappets.

Yo sup D series guys and girls..cbf starting a thread

so heres my story, I just got my fulls and was planing still go ahead with the B18c2 swap...atm im loving boost and not keen on any imports. I was looking on Ebay at cheap turbo Civic EK kits.

The question is will it do the job and running stock ECU still ?
will stock Motor and gear box handle it ....but running under 7psi ???
Insurance gonna hassle me ??


Its a D16y7 about 190k on the clock lol
