YouTube - WTF ??!? (http://www.youtube.com/watch?v=pIZUmhFKHR0)

Is that your car?

[northendtrooper]

Dude, holy shit. Tighten your timing belt!

[goblin]

If it is his car it's to late for that. Bent valves are in that car if I have to take a guess.

Kevin

[zex_cool]

nope not my car. timing belt is tight. no bent valves. 100bux to anyone that can figure it out...i cant.

[goblin]

That is what my car sounded like when I broke a valvespring. It is interesting that the sound carried on a moment after the engine had stopped. Certainly sound and looked like it jumped timing. Got me. A better vid would help. Be nice to see the rest of the bay.

Too late for another video. That sucks.

[bcool]

check compression. Its obviously having compression issues and with that noise i bet its in the valvetrain.

you are an idiot!! please GTFO!

[zex_cool]

it has good compression too. the noise is the valves that need to be adjusted..something that wouldnt make the t-belt skip.

this thing has been nothing but a pain in the ass since we got it from the shop where it was all assembled. the motor is a straight LS with brian crower cams, valve springs/retainers....

[northendtrooper]

you are an idiot!! please GTFO!

:facepalm:

[spastik]

is this gorons car?

[zex_cool]

it is.

[bcool]

Were the cams just dropped in or were the spec'ed out and lubed properly. I've seen it before where the cam had some play in the journal and that play would cause the timing belt to skip.

[bcool]

also i didnt know it had cams. that would explain the delayed starting. A little more history on the car and the issue would have been nice.

[zex_cool]

it was all put in by the shop that built the motor. almost the same thing happened when we first started it.
delayed starting was from the car sitting for about 2 weeks...and my base map. lol

[zex_cool]

btw, oem gsr t-belt and vtecH water pump.

[bcool]

as long as the timing belt has proper tension something is fucked in the valve train. tear the valve cover off and start looking it over. check the cam journals and make sure everything looks kosher.

we had the head off just for that reason and i couldnt see anything wrong! we put it all back together and the SAME thing happens. im just lost. i dont know what else it could be. again, 100 dollars to anyone that can fix it.

Did you degree the cams with a degree wheel? I'm betting cam timing is way off.

[goblin]

I take it the VC been pulled and there is not a socket or something laying around in the top of the head. Did you check piston to valve clearances?
I 'm grasping here. Looks like it time to start pulling things off and going through everything. Sorry I can't really help. Good luck and let us know what you guys find.

EDIT: Never mind I see you have pulled the head.

Kevin

[zex_cool]

one odd thing, the intake cam is a lot harder to turn then compared to the exhaust cam. i was thinking the springs might be to stiff but we got them all form the same company as the cams.

[carfreak]

First off on the t-belt tensioners do they use oil pressure or spring? And it seems like something in the head is REALLY stiff.

[shenrie]

Ive seen/heard of similar issues as this with budget cams from ebay that have really nasty (aggressive) profiles. Not that the ones you have are budget by any means, but they may be too aggressive for stock valvetrain components. Maybe the rockers are slapping???

Aggrissive squared off profile. Sorry, crappy pix.

End result...where the rocker was landing.

Granted, mine was not making that noise whatsoever, but I thought Id throw that out there sicne youve exhausted all other routes.

Maybe try some known good cams??

[zex_cool]

cam specs:

Adv. Dur. 280/280

Dur @ .050 204/204

Lift (in) .470"/.470"

ive talked to 2-3 different techs at brian crower and they all said to check the valve spring seat pressure.

[Jdmitr]

Is the head getting oil ok and did you get it figured out?

[zex_cool]

we got a stock head with stock valve springs/cams. we should put it on this weekend and see what happens. not sure about oil but the cams looked fine, as in no excessive wear.

[buster]

check for coil bind and guide to retainer clearance.

Good, if your head was being starved you would def see wear on the cams. What all work was done to the head in question?

[zex_cool]

check for coil bind and guide to retainer clearance.we will do that, but we just need to get it running now(w/ the stock head)! its been down for way, way to long!

nothing major. valve job, resurface, brian crower cams and valve springs/retainers.

and if anyone is wondering, this was all put together by Jims machine shop. better known as Jims and Dans.

[LS1Racer]

Molders or meridian automotive and machine FTW

[zex_cool]

meridian automotive is outrages! and i never dealt w molders. ill be taking the head to the guy out by the airport. i forget the name of the shop. same shop that does all of Jakes machine work.

[Moneypit]

I think the name of the shop by the airport is Moffit & braton something like that.

[zex_cool]

you are correct!!

[LS1Racer]

You pay for quality....

[Moneypit]

You pay for quality....

Im sure that JIms & Dans shop does great work. I know they do good work its just that something didnt go as planned and what can you do shit happens no big deal. Thers no need to bash on the shop that built the motor.
