Then a new problem developed. When I would run the car through the car
wash (with the underbody spray) the service engine light would come on and
the car would run really rough like it was missing on more than one
cylinder. By the time I would exit the car wash the engine would be
running ok but the check engine light would still be on.
Took it to the dealer and he checked the computer and it had thrown a code
for a misfire on 3 cylinders. Their mechanic said he thought the engine
had a vacumn leak through the intake manifold seal and that I was sucking
water and causing the 3 cylinders to not fire (sounded pretty farfetched
to me, but this is warrenty work so what the hell). So they resealed the
intake manifold again (I should mention that this is another dealer - not
the one who did the work the first time).Problem cured. Made it through
the car wash without throwing a code or misfire - but I am now running
ruff on an idle (another vacumn leak?).
The upshot is I have lost all confidence in GM. It's not like this is a
new engine design or anything. You know who is paying for all these
warrenty repairs - you and me when we pay for the car!
Waiting for the engine to run right before I do the mods.

Chris, I had the intake leak in my 95 TA, and it wasn't as obvious when
looking in the engine compartment as you'd think. I was losing about a
quart every 2500-3000 miles and could smell oil burning when I got out
of the car. There was a small puddle of oil in the front area when you
looked inside the engine compartment though, and that's what clued the
dealer to the problem. I had mine replaced about 1000 miles ago and it
now doesn't burn a drop!

When I had the problem on my '96 Formula, it was just a burning oil
smell. I checked the oil EVERY gas fill up and it never used any oil.
Once they replaced the intake manifold gasket, under warranty, the
smell went away.
Coming back from a trip to Indiana my oil light poped on and I was 3
quarts low on oil. This just after 1500 miles from having the oil
changed. Dealer ended up finding two different leaks. 1 on the
head gasket and 1 on the intake manifold. Sounds like a common
problem on the LT1.

I have a '96 SS that had the same oil leak. It is the intake manifold
and you can blame SLP for using a too thin a line of gasket sealer after
they enlarge the intake.

Just about all of us have it... not just the SS guys.
Methinks it's GM, not SLP.

I thought the ram air intake assembly was a simple bolt on deal for the Firehawks/WS6
and SS at least it looks like it was. I was unaware that the entire manifold had to be
removed to do this during the SLP conversion...do they bore out the manifold because I
thought SLP still used the stock 48mm throttle body?
I dont think SLP is to blame...GM. What did SLP do to your intake manifold during the
SS conversion?

SLP does obsolutely nothing to the intake manifold or heads. The oil
leak is because GM does not use enough sealer.

There is no requirement to remove the intake to add the assembly that
sets
on top of the intake and fuel rails. The owners manual shows an
isometric
drawing of the assembly including thottle body snorkel, MAF and air box.
To
install this does not require the removal of the intake. In fact if you
install the 160 deg. thermostat you find life is much easier by removing
this assembly and it takes a total of about 15 minutes and that includes
the first of several beers one would consume while doing the thermostat
change. The total thermo. change takes maybe 30 to 45 minutes and that
is working very slow. FWIW.

Okay, no arguement about the intake manifold, but your shots at SLP seem
a little strong. Where does your info come from? I have seen a lot of
stats from different sources that say there is a noticeable performance
gain with the SS. And more important to me, the seat of the pants, balls
to the walls test drives I took proved to me the extra cash was worth
it.
I drove at least 9 '96 Z28's, all brand new from different dealers. Then
I got real serious with the dealer of choice. I took 2, I repeat 2 SS's
for a ride I will never do with my own, and could feel the extra kick in
the small of my back.
Yes, SS buyers pay a heep of money, but we get it all right off the
showroom floor with a warranty to boot. The styling, "17 245's, leather,
6M, etc. The perfect poor man's Corvette!!!
My point is, we paid for the fastest F-body GM has to offer.

I gotta agree with that statement. I own a 96 Z28 and have been pulled on
the on-ramps by SS's. Its not a huge difference, but that extra 4 feet
the SS's consistantly get on me is enough to convince me that I need to
make a mod or two. hehehe.
Would *I* buy an SS? Nope. Nice cars, but not *that* nice. The extra
thousands could make a Z sit-up and run with a Viper. (Maybe not, but you
get the idea.)

Car and driver rated the SLP SS way above its supposedly twin WS6 but it was later
revealed that the Car and Driver Camaro SS vs WS6 vs Cobra performance test were a bit
misleading. The Camaro SS that SLP supplied had a few thousand miles on it whereas the
other two were brand new and that SS did have the exhaust manifolds extrude honed that
apparently production SS dont get.
> My point is, we paid for the fastest F-body GM has to offer.
Maybe and I like the looks of the SS but IMO a Z-28/Firebird and a few engine/suspension
mods would have been cheaper. I do like the Torsen Diff only available on the SS. later
To each their own......to sit there and be judgemental of another persons
decision to buy an SS is rediculous. Three grand for the SS package is
not a rip off.......if that is what you want. Colin was absolutely right
when he said that you would be hard pressed to get the equip. for less
that that.....you'd probably have to double the figure.
OK.....now that I have stated my $0.02 worth.....I do have a legit
item/question to add regarding this string.....
I have a '95 Z. At 14K miles, I developed an oil leak at the rear of the
block. The oil was all over the flywheel cover, transmission pan,
exhaust, etc. Well, I took the car in to the dealer and (amazingly) after
only 2 visits they managed to fix the problem. Turned out that the rear
main seal had gone bad (dunno why).
Well, now my baby has 33K on her odometer and I am again having some more
serious oil leakage problems.....only this time it seems to be leaking
down the passengers side of the flywheel cover (from in front of it, near
the oil filter). Is this the notorious Intake manifold prob. that
everyone is chattering about? I am gonna be calling the dealer again in
the next week or two to bring it in and I would like to know some info. up
front.
Thanks for any help

Yes, your right about making after purchase mods. for less cash. I
understand the thrill of the hunt that drives many of the guys on this
NG. This combination of finding the right parts, the right shop, the
right adivice, all at the right price can be very fulfilling. That
feeling of doing it yourself is great.
I am not blessed with that much time in this stage of my life. I run a
business most of my waking hours in that quest to make a ton of money.
Oh yea, I almost forgot, I have a wife and 2 kids that run around like
the energizer bunny! Keeps me busy.
My escape is this bad-ass car I bought after a profitable 1995.
Anyway, my purpose is not sound like a yuppie with more money than time.
I want to state saving money is important to a point. This point I
mention tends to change as you grow older. I'm 36 and my priorities are
much different than when I was 23 or 28, etc. I have no less desire for
speed, likely more because of my experiences. I simply want instant
gratification. Kinda like being in control of the remote.
The SS fills the void in my life much as I'm sure it does for many of
you guys. Fast car, unusual styling.
Please understand I wish my life was organized enough to take the time
to find all the above contacts. It is not, so I drag my tired bones from
dealer to dealer for 3 weeks, piss my main squeeze off for neglecting
her and kids, to find a race car. I do, it's called an SS.

Unfortunately, that's not the only blemish. You learn to live with
some, the warranty takes care of some and the aftermarket picks up the
rear.
The SS is a lot of hype, but the 17 inch 275 wheel and tire combo, ram
air system, hood, exhaust, Hurst shifter, "High" resale, better racing
shocks (a lot worse for dragging though), stronger limited slip make the
car worth while. You can not get all those "quality" goods for $5000 in
the aftermarket.
By the way my intake seal was replaced when I had the leaky rear main seal
replaced. The rear end filler bolt leaks too. All this leaking is making
me very nervous when my warrenty runs out.

I still think its an incredibly priced, well performing car. My 6 spd.
