Yea, couple hours ago i was totally fine with my car. Just finished doing a tune up it, running awsome.
I was hearing this noise for about a week now. Never inspected or started with the hood open till today.

Wtf could this be?
My oil is right at / maybe a little over the Max line. So theres no shortage, but maybe too much?

I have the camera pointed at where i believe it is the loudest ( that side of the engine )

Also i can NOT make it do this, it runs perfect fine. it ONLY does this on start up, when it reachs 1500 rpm or so, THEN when the rpm is dropping to the 700 idle rpm it makes this noise. And noise stops when reachs an idle

AND It does not do this on every start up.
its about 50/50

sometimes it does it, other times its perfectly normal.

I dont know where to begin...

 

What noise? The beeping?

or the rattling?

 

that rattle.
the beeping is my car starter in my hand


you hear the rpm raise OK
Than the rattle starts UNTIL it reachs idle

 

touch a screwdriver to the timing case, and put your hand over the end and then your ear, use it like a stethoscope. Then start the car with your remote start and listen for the rattle in the timing case. Sounds like you might need a timing chain tensioner.

 

i totally agree. Assuming you are high mileage, i assume it's chain stretch.

And ok, im mechanically inclinded enough to do all my own **** always have. I dont like payin $90 an hour to some old guy, so yea
How big of a job is that on these cars ? Should i wait till it goes for good?


So no ive never done one before but i absolutly love learning and tearing **** apart. I already decided if te motor blows im gunna rebuilld it. And throw some other upgrades while im in there.
Unless ofc a rod goes through the block, or a cylinder is scortched. Ill make that call IF it ever happens

 

181k kms
The l61

 

If you wait till it goes for good, then your gonna be replacing the entire motor. lol As far as i know as long as you have the tool for the top cam alignment then its just as easy as doing a timing belt on a honda.

 

Well you need to confirm that's where the sound is coming from. New chain and new tensioner. If you take your time and I think an average person can do it. There are several guides around to do it. Just have to double and triple check to make sure it's back in time when done.

 

Alright
Il do the scew driver thing. And post what happens.

Also is it normal for the tensioner to Only act up SOME times and rattle? Like i said its about 50/50 it took me 4 more starts for it to rattle again.

Pardon my spelling, im not good with the iphone typing deal

 

its possible, i cant say one way or the other though

 

sounds like the 5.4L f150s with hight miles after an oil change, sounds like its not getting oil up to the cams fast enough.

 

tensioner

 

See that was actually my first guess
I did add a can of some oil addive probably right around the time i first herd this noise.
Change oil and hope for the best? Easiet things first right

 

my lsj did that, and only on startup, just replaced the tensioner, and no more noise.

 

Same sound eh? Im at work right now. Someone will have a screw driver so ill let you guys know asap.
And wih my above post, i was refering to oil reaching the cams


And what kind of sound should i be lookin for when i use the screw driver? Just the same sound but LOUD i assume?

 

metal on metal, clack clack clack

just replace the tensioner, pop the old one out, pop the new one in, easy job

 

Ok i did the screw driver thing
There was definatly noise behind it. The clack clack sort of deal

Do these things go quickly? Would i be able to wait till the weekend ? Ill put on approz 5-600 kms by then.

 

Probably be fine, but do you wanna risk it?

 

I dont have a choice unless i get time off work
And seeing as im startin a new job next tuesday its not really an option

 

your probably ok until the weekend, order the upgraded LNF timing chain tensioner, ill see if i can find the thread with the part #

 

Im in canada will that make a difference?
If you come across any even hal asses how-tos lmk aswell

 

And shouldnt one for my car be fine? CAr is stock, maybe bolt ons in the future

 

i would almost say 100% its just the tensioner if it has only done it for a week or so i doubt the chain is stretched at all.
