Jay'Z Built Engine Health Diagnosis needed!! Engine Builders Opinions Pls!!
I am noticing this noise become more prominent and not sure if its coming from the cam area.. Is this noise normal on a built engine? I would like Engine Builders opinions and Built engine owners opinions.. Id like to be reassured its healthy.. Its been about 30k miles, the car is running normal at 35-40psi oil pressure at idle, 170-190 water temp even on hot days, and 15psi high boost.
Vid of noise.. <embed width="448" height="361" type="application/x-shockwave-flash" wmode="transparent" src="http://s40.photobucket.com/player.swf?file=http://vid40.photobucket.com/albums/e218/jonb7777/Enginenoise002.flv"></embed> |
Hmm...sounds like a normal built motor. I do hear some piston slap or valvetrain type noises, but nothing really alarming.
This was an SGP motor, if I remember correctly, and so far it seems to be holding up well, making good power, good oil pressure, and low oil consumption. I wouldnt worry. |
got noisy injectors like me too lol

g and g did all of there motors. assembly, balance, blueprint, setting cold lash, porting of heads, everything. all sgp did was bolt the head to the block and set the timing chains up. anyone that needs a good vq machine shop, go to them. joe is the owner, tell him jtran sent yall!

I have their 1000's......but still batch firing of them with the pro-efi 48 so with 3 firing at a time its noisy lol

Sounds great to me.
My stock heads make more noise up top than that, but I think it's mostly the injectors. If you close the hood and walk back about 10 feet and can barely hear it or not at all, then you should be OK. |
turn the radio up brotha.. thats what i do anytime i hear something i don't feel like worrying about :D

Jay, my vid is on page 32 of my thread. I thought they sounded similar, but after listening to yours again I would say that mine was MUCH louder, it sounded like a tractor motor :icon14:.

I wanted some opinions from Builders/Built Owners, as I have never heard any other built engines on idle close up.. Thanks though

Well if a stock block (mine) sounds like a tractor compared to yours, which it does up close, I'd hope that eased your fears a bit. Anyhow, good luck anyways!

Sounds like a built motor with aftermarket cams and injectors.
I have BC-Stage2 cams and HKS injectors (1000cc) and at idle you can definitely hear some valvetrain noise with the hood open and hovering around the top of the engine like in your video. If you have healthy oil pressure and good power under boost, not burning oil or any smoking or missing coolant,... then I vote no worries and enjoy the car :) |

normal on built VQs, dont worry
|
That isnt **** compared to mine, which sounds like someone is hitting the manifold with a hammer.
And no its not rod knock or anything, Ive been driving with the noise for ~10k miles |
Ok, anyone care to post vids of their engine on idle? Just for true reassurance.... :hello:
