HEY GUYS I HAVNT POSTED IN AWHILE I HAVE A 98 CIVIC EX STOCK D16Y8 THE OTHER DAY I WAS DRIVING THROUGH THE HARBOR TUNNEL AND I WAS PULLIN PRETTY HARD HIGHEST WAS MABY WAS 6500 RPMS JUST BEIN GOOFY CAUSE OF THE WS2 EXHAUST IN THE TUNNEL SO I COME OUT PAY THE TOLL AND BEFORE I MAKE IT OUT CAR BOGS OUT START IT UP GO DOWN THE STREET ENGINE STARTS TAPIN OR KNOCKIN OR SOMETHING STARTED A LITTLE LOW THEN GOT REALLY LOUD ALMOST MADE IT HOME BUT DIDNT WANNA MAKE IT WORSE THAN IT ALREADY WAS FOUND OUT BEFORE I PROCEEDED HOME WAS 1 1/2 QTS LOW ON OIL HOW I HAVE NO IDEA I REALLY GOOD ABOUT KEEPIN UP ON THAT STUFF WHATS IT SOUND LIKE I GUESS IN BENT VALE IT SOUNDS LIKE THE 2ND IN FROM THE PASSENGER WHEN FACING THE ENGINE IF ANYONE NEAR MD HAS A DIRECT SWAP OR SOMETING CHEAP LET ME KNOW I GOT FIRED CAZ I COULDNT GET TO WORK TRAINING SO NO BIG SPENDING RIGHT NOW

 

I need laser eye surgery after reading that.

 

why is that

 

Chances are that you didn't bend a valve at 6.5k...Are you sure that it's a valve tapping? Could be rod knock. Does it get louder by rpm? Oil starvation at high rpm is bad.

 

yes sigh............

 

have you adjusted the valves? it may not effect the performance like you said but its something you should keep up on. it'll also make loud knocking or ticking noise

 

Rod knock from bearing failure due to oil starvation?

 

Yep, or at least thats my guess, Y8s aren't axactly known for having the valve train fly apart, they are however known for spinning rod bearings, especially if you let them get low on oil. That and from what the OP stated in the original post thats pretty much dead on for a spun bearing. knocking starts out pretty quiet and just gets progressively louder.

 

yeah that can happen. to much metal to metal rubbing wears away the bearing fast

 

so with my y8 burning oil (~quart a fillup) from valve stem/seal should probably be kept at mid RPM (4 - 5k) ???

 

oh and if you get it to low VTEC wont work. i know. i done it lol

 

thanks guys for all your help so pretty much just sell it buy another swap anyone want a complete d16y8 lol with rod knock

 

Because reading a post that is in all caps is annoying.

 

O SORRY LOL jk i figured readin caps makes it easy

 

That's like making the assumption that fat ladies in neon spandex are easier to look at.

 

*shudders*

 

youve spun a rod bearing ive done it my self. really common in y8 blocks. with that said your motor is shot. find a d16z6 and do a swap try the search engine( type in "d16y8 to d16z6") to find out info on the swap ill help you to get a start. this is the best one ive found when it comes to info buy theres 8 more to read over

thanks a mill man really apreciate it

 

Rod Knock, doubt it woudl be a bent valve unless you skipped timing or something.

 

@Dkober101: nice link and details.

how come HMotors does not have a z6? is it not a common swap?


found in:

# 1991-1992 Honda civic si
# 1992-1995 Honda Civic EX, EX-V and SI
# 1992-1995 Honda Civic ESi (European Market)
# 1993-1995 Honda Del Sol Si (US)
# 1993-1995 Honda Del Sol ESi (European)

 

Because its not JDM, you can find JDM SOHC ZCs which are essentially the same thing, or D15B Vtecs which are similar.

 

Anyone wanna buy a 1.6 y8 lol block and head no trans
