maybe a roller lifter? Maybe a pushrod yip? is there oil coming up through all the pushrods? I would check all the tips and adjust. If that doesnt cure it then I would look into the lifters.

 

Post a video of the sound for starters. A visual/audio reference will be far more effective at helping us determine your problem far better than typing ever could.

Also, what are your mods, specifically? Like valve springs, rockers, cam choice, timing chain, oil system, etc. How many miles on this "build"? Any problems before or recent engine work? Gotta know these things as well.

When you mean one quart low, do you mean below the ADD mark on the dipstick? Or (hopefully) you mean it's at the ADD mark? Hopefully you know better than that...!

 

A squeak means no oil. Not good. I would pull the valve covers and have a look at the topend before you fire the motor again.

The last time I heard a motor squeak it had a spun bearing. It was pretty loud though.

 

ima go aheads and post start up video and a lil rev so u guys can hear it and take it from there

 

Agreed. Check your rockers to see if they are getting oil. Take your belt off, start up just to make sure it is not an accessory.

 

videos are up 1st post

 

It's time to pop a valve cover.

 

^^^ agreed. you can rev it up and show use but your taking a chance. i would deff pull the valve cover and look.

 

this is my dd i have to be driving it like this..for now need to get it fixed asap

 

Pull the VC that should be pretty easy to find.

 

The last time I heard a squeek/tick noise like that, it was a flat spotted roller lifter. You'd have to pull the intake to get to that.
However, if that were your issue and you haven't re-adjusted the rockers, you may find a loose rocker on that pot when you pull the valve covers, IF it happens to be sitting on that flat spot on the roller.

 

was it an easy fix ?expensive fix

 

Sounds like a bent pushrod, broken spring, exteremely loose rocker, broken rocker,Bad lisfter....

Pull the valvecover and take a looksie.

 

i hope its somthing loose.last week i took it to the track that was the only place where i floor my car and stuff..when i left my car was fine.all week long my car was fine .i leave the car parked for 2 weeks it does this ****

 

You SURE no one else other then you has access to the keys? I learned this lesson the hard way....

 

yea im quite sure ,even thou i got like 4 original spare keys

 

Just a thought, Something like this happened to me a while ago.

Id do what everyone else is adjusting and pull a vale cover and see whats up. You really don't wanna drop a valve or something and wreck the new build....

 

You said it was a quart low on oil, I'm going to assume you topped the oil off, it sounds like a bad roller wheel on a lifter in which case you could also have a wiped cam lobe. And if that's the case the metal circulating thru the engine will wipe your bearings out. If it was me I'd stop starting/driving it immediatley and change the oil, look to see if it has anything shiney in it. Also as stated I'd pull the intake and check all of the lifters and cam lobes.

 

Well guys i wanna go ahead and that every one in this thread for helpng me out with their sugestions,appricate it.just finished up taking off the valve covers and thaking a look at it.evey thing looks good make sure nothing was loose ,nor nothing.till i found out wat i was.it was a simple exhaust leak.!one header bolt was very loose.got it back tight.fired her up took her for a spin and it was like a dream everything was just fine ! ..thanks everyone for looking into and reading my thread..have a great day!
