Argh, i'm so f**** pissed...

So the new built B18a1 idled and ran BEAUTIFULLY... i love the torque of it...
Screw Vtec, who needs it... I've got 600 miles on it so far.

ANYWAY>>> Drivin home today... i did a couple little 1st and 2nd gear pulls... In the middle of second... my car bogged and popped to ---- for a SPLIT SECOND @ 5k rpm, then kept going just fine. Felt like WICKED bad detonation... but WHY?!?!?! i come to the light before my college... And i hear a tick tick tick tick.... It never did that before... and i had perfect air fuels... and no detonation... And now this?!

One tick per every revolution.... For a second, i said it CANT be my car...
I got home, and YEP!!! IT'S MINE... wtf.

TT rods, ACL bearings, Wesico pistons, ARP head bolts... everything else is stock.

No smoke whatsoever... So i doubt its a cracked ringland or such...

Think its the Rod bearings? Spun a bearing possibly? I dont hear the tick when its driving... only @ idle... and it's very pronounced. Valve? Rod bearing?

Rod bearings are easy to replace. Drop the oil pan, and pull them out. Crank bearings SUCK...

What do you all think? What does rod knock or spun bearings sound like? Or whats a cracked ringland sound like? Or anyone think it may be a valve, or lifter?

 

something that doesnt like low oil volume/pressure

 

exacly right , sounds like a bearing to me.
same thing happened to my brothers GTiR , ticking noise at idle.

 

---- i hate bearings...

I just changed my oil too after break-in!!!!

I went to full synthetic tho... that aid in this?

It couldn't be a crank bearing i dont think... It's gotta be a rod bearing right? i'm soooo ------ pissed... i just fixed all my exhaust leaks, changed the oil... engines just now broken in... and it idles SO DAMN SMOOTH and quiet!!!... ---- this.

 

Yeh normally when a shitty oil is used and then you run good oil , good luck man bearings sux bigtime

 

Have a go at removing the oil pan , that should reveal the answer

 

sounds like a blown headgasket to me, mine ticked crazy when i did this

 

haha, damn, ugly pics!!!

I'm 100% sure its not the HG. ARP's, and only 9lbs... No overheating or nothing... No smoking either.






This weekend i'm deff pullin the oil pan... Hopefully its just some rod bearings... 30$ an a 2 hour job... HOPEFULLY!!!

 

good luck and hopefully its nothing too serious. how does the new built engine feel, besides the tick? Fix this problem, up the boost, and get some ripper vids. I'm excited

 

go Buy a steathascope so u can hear where the noise is coming from.
