oh no ****? so youre saying im safe? well i remember the pic in your sig n they looked nicer than mine, like the ferrea but i guess my eyes were mistaken. 78 is what i have (the ones that dont require the smaller seal)

when would you be free to time my motor? i get home from erie thrus nite but im free til sunday around dinner. i dont have any of the tools except a degree wheel, magnetic dial indicator (no good for aluminum heads lol) and a timing light (no distributor on our cars)

and im really glad im talking to two guys who have done work with the valvetrain already. thanks bry and al

me dos

Hey, It sounds to me like the timing is off quite a bit. If its tuned and it still wants to die then the timing is off. Before you put the cams in did you rotate the crank by hand to top dead center and after you put the cams in did you align the cam gears in the right place????

whoa thats some **** right there lol

Im going to post a new video of mine so you know what's normal for reference.

Just as an FYI the stock chain tensioner can seize itself if you don't have the latest one.

If you pull it out and it has a green rubber ring that is the old style and can seize during normal use which would cause your chain to skip a tooth or just for the chain to slap around your front cover and sound like bad lifters.

Yeah thats what it sounds like on mine when it first started and i don't know how his sounds right now.

stage2cobaltss

where are these stage 2 cams located? what site. im intrested in getting them

Witt

Yeah the 78s are fine, a lot of us run them on aftermarket cams and I don't know of one person with any issues. I was the reason that kit now comes with seat locators due to concern over inner spring to seat/seal wear.

Thursday or Friday might work. Saturday I'll be at the track and Sunday I'll be at work.

massivematt

i'll have a new video up in about 10 min. It is cold where im at so it will sound smooth for a minute till it warms up. Hopefully it will help as far as what you should be hearing out of the engine.

Ok here is what you should be hearing.

So Matt does mine sound normal???

I love how people on here think they know everything. Supertech's .547 lift is if they are installed at a NON stock height of 1.375, at stock height of 1.21" they can only handle .395 of lift. So I doubt you had a blank head with extra materal added to make up the difference. Here is a diagram of the supertech and some psi springs that I found to help explain it..




Now the supertech 76lb springs can handle up to .445 of lift at the stock ecotec spring height.

Well here is my vid's sorry for the quality it was on my cell phone. Only thing is when i turn off my car it feels like it just stalls out instead of like normal turn before cams, and you don't hear that drop of air from the intake anymore.

massivematt

yeah it sounds like the timing is off.

Witt

I love how people on here flame but are still incorrect, its just better when they copy pasta other incorrect information from other forums.

Valve spring installed height is 1.210 inch on non stock valves.

Yeah i believe o3nisoaso3 is having couple buddies over to time our cars better. Witt i believe is one

o3nisoaso3

yea, timing is off, i knew that but the mechanic that was helping said it was fine n was mechanical on both cars. and yea we did the rotation of crank n held gears in place (cam gear tool) but may have gotten a tooth out on exhaust then the mechanic changed mikes (MP Cobalt) and that started his noises, my tmiing is the same as his (maybe a tooth or two off) but my car starts the same n it will idle on its own

well thursday nite i got home from erie around 8 and friday i get home from work about 430 so whenever youre free. PM me if you can make it out and ill give you some directions/address. and would you mind to do MP Cobalts car also?

slowswap

You have to bleed the lifters when you swap cams....

MP Cobalt

iTrader: (4)

bleed the lifters? like let all the oil out?

Witt

We can shoot for as much as we have time for.

We will have to pull the front cover and re-time it that way.

o3nisoaso3

bleeding is like repressurizing them (in terms of brakes) like let out the air in them? im not sure what he means so im waitin to see. and mikey go on aim in bout 30 mins. im goin to shower then ill be back on

slowswap

Yup. Evo guys have problems with excessive valvetrain noise because they don't bleed there lifteres.

http://www.youtube.com/watch?v=gKX2pYVO0Ak Theres a video on how to do it on the 4G63.

o3nisoaso3

haha yea. well im sayin that i did mikes whole car in an hour. and we can have both cars ready where you just walk from one to the other and do your thing with the timing and then we will bolt everything back up

ok nick ill be on in like 30 minutes. my CEL went off today? i don't know how but it did. So i don't know how that's possible

o3nisoaso3

were you tryin to drive it hard? any heavy accel? go on aim well talk bout it

i talked to supertech, they said that with 78lb springs installed w/o any head modifications it will handle .540 lift
