Project finished, doesn't look good.

Re: Project finished, doesn't look good.

glad to see someone is concerned for me lol :tup:

I was thinking about it this afternoon...

I never did hear you say it was backkfiring?
If it was backfiring, you'd know it.
Sounds like it runs ok without backfiring for a minute or two or three, then floods out and stalls.
I'm going to suggest a fuel injector "stuck open" and/or too much fuel pressure.
Sounds like it quickly floods out a couple of plugs, blows the unburnt fuel into exhaust, and the motor can't run anymore on just a few good cylinders.

If you've got fuel shooting out of the exhaust pipe, sounds like you have exceessive fuel and lack of spark...not a valve adjustment issue.

If it was just valves out of adjustment, and the fuel and spark were close to right, it would be burning/exploding all the fuel while backfiring like crazy through the intake and/or exhaust.

good luck, keep us posted!

tko, check out this recent thread (was a 3.8, but similar problem) :

Re: Fuel Smell and RPM's

About 15 minutes ago when I started my car, the RPM's were jumping between 500 RPM and 1500 RPM, running really rough, and noticed a strong fuel smell. I got out and went to check my exhaust, and it reeks of fuel.
.....
Got it fixed. Number 2 injector was stuck open. I bought 6 new AC Delco injectors from the dealership and did the install my self, with the help of a buddy who is an aircraft mechanic. 6 injectors x $143 = $858 in parts, labor cost me 2 cases of Bud Light.

here's something similar for a 3.4 from 2003, looks like intake manifold was loose :

i should mention it has been backfiring like crazy. I'm pretty sure its the valve adjustment, at least thats what i'm hoping. The injectors were good before i did this project so i'm gonna go ahead and say they're prlly still OK. I will keep you posted, a solution seems imminent either way.

Re: Project finished, doesn't look good.

i'm a plug whore :cool:

i change them whenever possible, but your right , it isn't necessary.

brian, do u know why my car eventually stalled out and died? it shot out fuel through the tail pipes and then eventually it just wouldn't start.

i know that it has to do with the rocker adjustment but i'm still curious as to the physics of it all.

thanx

Uncompressed air/fuel mixture is allot harder for the spark plug to ignite then a compressed mixture.

Re: Project finished, doesn't look good.

Hopefully you did not damage the cam, push rods, or lifters if the valves were that far out of adjustment.

my unc says nothing should be damaged.

On a different note my dad thinks i blew head gasket cuz when i took apart my valve covers the oil was real vanilla like and he says it would explain the gas coming out the tail pipes, can anyone dissprove that theory for me because i am really worried about a blown head gasket.

Re: Project finished, doesn't look good.

How long did the car sit with out being run? Do a compression test while your waiting for the plugs, After the valves are re adjusted.

it sat for about 3 months w/out bein started.

But right now i have a huge update.

As you know i took top end apart again and as i took off the valve covers i saw the oil was milk shakey like. So i let out the oil from the oil pan, and lo and behold it was pure vanilla milkshake!! all of it!

I called my uncle right away and he doesn't think it's a head gasket since those were fine BEFORE i started this project, but my dad thinks it could be the head gasket since i ran the car for 5 minutes with very little coolant... the only thing it could be (or at least i hope it is) is that i installd the LIM gasket wrong somehow??

if the LIM gasket was not working properly would it cause this milkshake oil problem??

I haven't taken the LIM out yet, but i have all the bolts out, so i just need to pry it up off the corner studs really.

Please just tell me its NOT a head gasket issue.

any thoughts? i'm very distraught.

Calm down...you didn't mess with the head gasket...sure would make sense it was a LIM gasket since that is what you were messing with! :)

thanx man i freak out about this ****.

I know i didn't mess with it, but my dad says since i ran the car with very low coolant for a bit, i could have blown a head gasket, but i don't know if thats true or not.

Broken-down oil ("vanilla milkshake" as you call it) is caused when coolant and oil mix. Coolant and oil can mix at either the intake manifold gaskets, or the head gasket

the only thing it could be (or at least i hope it is) is that i installd the LIM gasket wrong somehow??

That is appearing to be the case

if the LIM gasket was not working properly would it cause this milkshake oil problem??

yes

Re: Project finished, doesn't look good.

thank you smokey.

in your highly regarded opinion, would you suggest it is in fact my LIM gasket that is the problem?

also, i can't see how i installed it wrong, the gaskets simply snap into place with a little tab and then i used black rtv in the LIM valley and torqued it down to specs, so i don't know what i might have done wrong.

Re: Project finished, doesn't look good.

What was the reason for tearing apart the top end again, I do not remember. Was it running bad before? Overheating? Milky Oil?

[bigbrian442]

Re: Project finished, doesn't look good.

Did you change the oil after you put everything back together, before you started it? You could have let the coolant in when you took the intake off 3 months ago.

i put oil in a few minutes before i started the car.

I took apart the top end to add new rocker arms.
