'98 Z71 w/5.7, 78k miles, looks like the intake gaskets are starting to
leak... (from reading some of the other forums, it seems GM's got a problem
with this intake manifold) Anyone had any luck getting the dealership
correct the problem?
If I'm going to take the time to change them, I want to install the best
available, what's the best brand out there to buy?
Steel core instead of plastic, laminated rubber over the core
instead of rubber inserts.
But you have to request the right part number, Fel-Pro also makes
replacement gaskets that look just like the OEMs.
The part number for the VIN "R" 5.7 is
Includes 2 lower manifold gaskets, 1 valve cover gasket, 1 upper
plenum gasket, 1 throttle body gasket, 2 fuel line o-rings, 1
distributor base gasket, 1 small tube of RTV.
Price: $55.00 wholesale, $80 (ish) retail
Also available for the VIN W&X 4.3, VIN M 3.1, VIN E&J 3.4
- been using the MS98000T for about 6 months now, no failures but
it's probably too soon to tell.
When I hand mine changed this spring under warranty, I asked them about
it directly and looked at them too and there was no change on the ones
for my 2000 5.7. You may work on them daily but I still do not have much
faith in some of their gaskets. They pulled the tcase twice to stop a
oil leak between tranny and Tcase on same seal.
I am wondering at this point if the gasket is bad or could it just be a
warped manifold that started this mess in the first place... Rockauto has a
new manifold for about $60... since I'll have the thing torn down anyways,
would you replace the manifold at the same time or take a chance and assume
the old one is OK?
Mine was 10 years old at the time. There was galvanic action between the
heads and the intake, so a new intake and gasket did it. I am disappointed
to hear these problems still exist, so who's fault is it really that Toyota
is approaching #1?
Having owned vehicles manufactured by Honda and Toyota as well as those
manufactured buy all current American manufacturers, I can say without
reservation that the best vehicle I have ever owned (reliability wise) was
and is a Chevrolet. One of the most problematic vehicles I have ever owned
was a Honda Civic.
I wish your words were more true for my Tacoma can't pull a load like a Ford
or Chevy. Another big block gas or diesel is in my future, and I am
undecided on brand other than 3/4 ton and less than $35k
