is it like a loud ticking noise or what does the noise actually sound like?

 

could be low on oil, god damn lsvtecs

 

thanks for the response...... n yes is a loud ticking like tick tick tick tick especialy when the engine is super cold is like is not get in oil on top but i took off the valve cover and man i start the car n it make a mess w/oil all over oil p.s.i is 80 cold 35 when is hot press the gas n go up to 80 again when the engine warm up it quite just a little but you drive it runs fine but if you push it around 2,500 up to 4,500 sound like crazy lose valve and they are perfectly adjust it drive me crazy ... u think is bad head ??? i send another one to the machine shop just in case

 

What kind of oil pump did you put in the motor? Have you check to make sure everything in the head is tightened??

 

did the machine shop check for valve clearance? could be a possibility

 

check your lost motion assemblies.

 

i have stock ls oil pump why is bad ?? which one should i use ? i check twice the head and everything still tight. see i was running 5w30 to break the motor i change to 10w30 to see if the noise go away because of the thickness but nope still there is weird man even i took the car to the machine shop n the guy said the same thing weird he told to take the head off and bring it to double check because he adjust the valve almost dead end n still sound like diesel truck any help is appreciate it thanks

 

i change the lma's twice man and nothing

frustration is killing me

 

^^you're gonna wanna change that stock ls oil pump ASAP, what year is the block??

If its a 1996+ block, then your oil pump will be fine as-is because they all come with P72 pumps... but if not, better change it QUICK, i had an LSvtec blow up on me in 5 days due to the pre-1996 stock ls oil pump being on there...

And all that extra noise you're hearing is most likely the head starving for oil. The pressure numbers could be correct, but the volume of oil actually being pumped could be not enough.

 

you know what your right the block is the 1st gen how i mist that thank you so much i will change that asap

 

i'm glad they got to answer that about your oil pump for you, I was asking cause I was going to tell you the same thing lol. I'm glad they told you. but yet just get that changed out and see what happens from there.

 

thanks all of you for the help i will let you guys know tomorrow.


will i did work in my car today and i did change the oil pumpi put a j-spec b16 plus i put a little washer between the spring inside so i created more pressure ......here comes the but ......but the noise still there idk what else could be it sound right in top like the in the valve train i check i re adjust the valve and no luck i think i going to pull the head off and take it to the machine shop for inspection
