ok i changed the timing belt and water pump, put everything back together and started her up...loud noise from the head(i think) happens immediately and the header gets hot after 1 minute and light smoke comes from the exhaust side which smells like celery ha...all cam marks and crankshaft marks were lined up perfectly....
here is a video of whats going on; i revvedit up after a minute-all help is appreciated!

well couldnt hear the video cuz my speakers are messed up but did u replace the timing belt becuz u snapped the othere on if so you prolly got bent valves

 

no it wasn't snapped the original was actually in good condition and i replaced it anyhow along with a gsr water pump...replaced the tensioner as well

 

car ran like a champ before i messed with it...only thing wrong was the water pump was squealing before this job

 

sounds to me like the cam and crank timing is all wrong

 

wait a minute your running a gsr h2o pump in an ls? that's your problem. there's a big difference.

 

yea but i'm also running it with a gsr timing belt only difference is 3 teeth...do you think that i bent a valve....

for instance, what happens if you spin the crankshaft without the spark plugs removed and cams not attached??

 

the gsr timing belt is not only longer because of the the water pump but also for the location of the cams. the cams in a vtec head sits higher than the non-vtec head

you gonna have to start over with the right parts and do a comp test to find out

 

the belt barely fit on though i was struggling to get it on with the tensioner bolt loose...

 

i dont know for a fact that it wont work.

but i do know there's a difference between the pumps, head heights, and belts

there's also an order the belt goes on. it's super hard to get it on if you dont follow the order

 

yea i put it all on in order...everything seemed fine...

what does the celery smell mean though?? maybe tha the air isnt leaving the head as fast as it's coming in??

 

why would you put on a gsr timing and water pump on an LS in the first place?

 

because the water pump spins less at high rpms

That was a very uneccessary mod. Swapping a LS water pump should be the least of your concerns.

 

the gsr one is cheaper for some reason as well..i figured why not when i had to change it anyhow...the original was squealing at normal temp...

 

celrey is one of the things people say coolant smells like when its burning i think it smells like something sweet you should just put the ls pump and belt on it

 

yea but what i don't understand is how people put it on their ls/vtec and everything is fine...why would it be different in my situation? i even torqued the bolts down to 16 ft lbs...
if you're going to say the cam height i don't think so cause it barely fit on with the teeth lined up....
and i didn't have any white smoke come out the exhaust...
please help h-t i need you now more than ever...watch the vid and let me know

 

oh dude i just watched the video you definetly bent the valves i think there hitting each other just find another head and no im not just trying to sell you a head i dont have one for sale i just know that sound and you probably still have compression its out of time and the intake valves are hitting the exhaust valves but if you can change the timing belt you can change the head the belt is the hardest part

they did help you, and told you what you needed to fix. You have the wrong pump and belt.

 

Yeah, it's not sounding good there buddy.

A good word of advice is to always turn the engine over by hand before you crank it. I tightened my timing belt recently and did just that: Turn it over by the bolt on the crank pulley a couple times to make sure all was well.

Double check that your timing is good and get the correct timing belt plz.

3 Teeth is alot.. 1 tooth is ALOT. Only the correct timing belt is acceptable buddy. I do believe you probably just cost yourself a new head. If your cam timing is dead on 100%: Yank the head and look at the valves.


But hey, look on the bright side! You can guy a GSR/B16 head and do an LS-Vtec now

 

i understand what you're saying about the teeth difference but i thought it was an even trade as far as...22 vs 19 teeth on the pump and 3 extra teeth on the belt...
wow this really blows...i have to remove the head just to check...
if anyone else has any advice please feel free to post or as soon as i remove the head i will post pictures to get more advice from you guys...
thanks for the help-cheers

 

the extra teeth on the pump and the belt is what makes up the height difference on the vtec head the valves are hitting each other sorry to keep giving you bad news maybe if you get the ls belt and pump it will run ok but i think you would be wasting your time and theres probably some coolant on the outside of the block somewhere thats burning off

 

i understand what you're saying but if i were to spin the crankshaft 4-6 rotations and all the marks line up perfectly what's the difference??

 

woops posted in wrong thread!!
