Lifter knocking

Dolbs4082 · December 4th, 2009, 01:43 PM

I built a 5.0L stroker motor this past summer for my 01 gt. Had a professional assemble the bottom end and do the timing for me. I've taken it to the track a couple of times. and the motor runs strong.

But now for some reason theres a loud ticking noise, coming from what sounds like the drives side? at first i knew it was the throw out bearing, so now theres a new throw out.

I've had several people listen to the motor and say that it sounds like a lifter is knocking. Is this even possible when you have a roller rocker like ours?

because this is an extremely loud and annoying ticking that scares me pretty bad haha

ive never heard of a liffter on our cars knocking before... maybe a valve tick.. but that doesnt seem to be your case..
is one of your rocker arms getting ready too come off?

Dolbs4082 · December 4th, 2009, 02:02 PM

im not sure, im hopefully going to have the valve covers off of it next weekend to check and see. i would hope the lifters not fixing to come off? now what would cause the valve tick tho?

edit- ive also noticed now that its cold out its alot louder?!

SWEET2KSTANG · December 4th, 2009, 02:03 PM

we got lash adjusters and there have been instances when they have caused a tick. its not a very common thing at all, i ran into an adjuster issue when i built doc's motor. the issue was evident upon start up, not miles later.

Boostang · December 4th, 2009, 02:06 PM

if the lifter comes off youll know it cause itll seem like ur firing on 3 cylindrs..
but low on oil.. bad seats..
^^things that make a valve tick

Dolbs4082 · December 4th, 2009, 02:39 PM

hell i've got brand new heads, and just changed the oil in it less then 250 miles ago haha. this is really starting to bug me. and people do say that it sounds like im running on a bad cylinder. this damn motor has been a headache for me haha

Stark77 · December 4th, 2009, 02:40 PM

Did you build up a 5.0L pushrod stroker or did you stroke out your 4.6 to 5.0L? In either case, check your header/exhaust manifolds on the side of the engine that the noise comes from. If it's a pushrod 5.0L motor you may want to check out the lifters, if it's a 4.6 I agree with the person above who said to check the valve seats(seats or seals?). Another option, which I would HIGHLY RECCOMEND is a seafoam smoke show. Put some in your gas, some in the crank case, and vacuum line some into your plenum/manifold.

Dolbs4082 · December 4th, 2009, 02:44 PM

its a modular 4.6L stroked to 5.0L, and i've checked the header to the best of my knowledge its all tight. im half tempted to pull the motor next month ( have to change the clutch anyways) and that way i can go threw everything and make sure its all tight.

limited · December 4th, 2009, 02:51 PM

If your header has provisions for egr connection, check that area also

Dolbs4082 · December 4th, 2009, 02:54 PM

ooooooo, now theres a good spot to look, i hadnt thought about that one! thanks man.

im affraid even to check that tho im gonna end up having to just pull the damn motor. which really isnt that bad of deal, i've got alot of little stuff i would like to do to it anyways to get it ready for next race season.

Stark77 · December 4th, 2009, 04:43 PM

Fractionally bent valve?

Dolbs4082 · December 4th, 2009, 04:54 PM

thats what im super affraid of. question is, if i were to accidentally over rev my motor, could it cause me to bend a valve some how? i dont know that i have done that but is it possible?

Boostang · December 4th, 2009, 05:25 PM

put it this way if u bend the vale enough where it wont shut all the way it may hit your piston and cause more damage than you can imagine.. metal shards flying at your cylinder wall/combustion chamber..
it could get nasty..

limited · December 4th, 2009, 05:30 PM

didn't patriot heads have valve guide issues? a loose guide could create a tick also(like the famous cobra tick)

Dolbs4082 · December 4th, 2009, 05:30 PM

ummm....

Im familiar with the term, piston to valve. lmfao

You know, now that you mention that, i do remember hearing that contravercy of whether the patriots are good heads or not? maybe im the unlucky soal that got a bad head?!

Boostang · December 4th, 2009, 05:32 PM
