i could be wrong but it sounds like lifters.

were you running your car hard then it started suddenly?

awhile back i was really beating the hell out of my car trying to hardest to keep up with turbo'ed eclipses (back when i didn't have my hahn). after one night of driving my lifters started hitting. I parked the car over night and by the next day the sound was gone. my friends and I thought maybe i ran the oil thin. the sound hasn't come back.

id definetly check / change your oil.

last time i changed my oil, i ran 10-w 40 by accident. i get a little bit of lifter tick on a really cold start, like in the morning. or if it hasnt been started all day. just till it warms up though.

 

[MitzEclipse]

i use castrol gtx 10w30.... i think im goin to go for 20w 50 because im always redlining my car

 

[MitzEclipse]

21 is the rocker arm
20 is the valve sprin
3 is the cars head
Underneath or in between this
is where cams and lifters will be on
connecting to the push rods.

yep 21.. is the one thats makin noise the rocker.. umm i can tell its like right next to my valve cover... u can hear it... only when the car is cold.. and when i acclerate slow... im not losing compression tho.. do u know how much to fix it?.... i checked my oil too everything is okay im not burning oil thank god .... umm should i use 10w40 or 20w50??

 

[Gyger]

is it pretty loud or soft? I would try and use a higher octance then normal if that doesn't have any effect. Pull the valve cover and
see if it's loose or warped. If it is you could go cheap and get
one from a junk yard. But I wouldn't do that to my car. Buy a
entire new set from Summit racing or a speed shop around you.
They are pretty simple to replace. But make sure you have a Haynes
or chilton's manual with you so you know what the torque specifications
are.

i have another head from another motor .. so can i just take it out of that one

It honestly sounds like a spun rod bearing. I wanted to believe that the sounds my engine was making were coming from the head as well, but they werent. Does the rattling get faster with engine RPM?

 

[MitzEclipse]

yep... but when i gas it hard... u cant hear it anymore... only when im like doing 0-25mph... and i have the gas pedal halfway.. u hear something loose... rattling in the motor

 

[Sinner]

it does sound like the rocker, my car has a problem with the rockers ticking it started about 10,000 miles ago but I don't car much cause I plan on doing an entire rebuild and turbo kit to my motor. My ticking sound like the same as yours, ticks pretty bad when it's cold and at low rpm's but when i get into it the ticking goes away. If it was a spun rod bearing then my engine would be toast a long time ago, also a rod bearing is more of a knocking sound than a light ticking.

 

[1TuffRS]

have you been late on changing your oil, or has the oil light come on?? When I had a spiun bearing my oil light came on when I took turns

 

[MitzEclipse]

pressure light came on.. i guess the oil light i only ahd 2-3 quarts of oil... so i changed the oil... noise calmed down.. but came back up .... i check the oilevery week oil is still good =) always on max

old mechanics trick for ticking lifters; take either a 1/2 qt of automatic transmission fluid or a small bottle op brake fluid and pour it into your crankcase. only leave it in the engine for 500 miles, at the 500 mile point drain and change your oil. the atf and the brake fluid both are really strong cleaning agents. usually when a lifter/ rocker tap is happening in an engine, there is either varnish or choke(carbon) build up inside your lifters. the atf/ brake fluid breaks it up and gets it out of the lifter. it's cheap, efective,and very easy. if it doesn't solve your problem then you know it is something worse......

 

[MitzEclipse]

chill idk about that puttin atf in my car..

 

[MitzEclipse]

great i just blew my motor... my uncle said their was no oil in the motor... and im gettin mad because i changed the oil 12-10-02... i thought i cracked the oil pan.. but i didnt... my uncle said my connecting rods and crankshaft just went....

 

[DSM90B]

mine did the same. timing is off and she was low on oil. fixed my problem. peace.

 

[DSMtuner]

sound like valve tap, use a lower wieght oil, see what happens. if so look into replaceing your springs they might be to compresed.

 

[MitzEclipse]

i still got warranty on my ##### so im good.. their sendin me anothe rmotor... agian this is the 4th one.. piece of #### 420a
