: It's my understanding that to do the Belly pan gasket, you have to remove the intake manifold etc, right (not sure exactly what the belly pan gasket is, just how to tell if it's blown..hehe)? If so, figured since while it's apart, might as well put a better intake manifold on.... Especially if I get a good deal :)
That is correct - to fix the belly pan gasket, the entire intake
manifold must be removed.
:What are the pros and cons with going this route?? Thanks
The pros are no more belly pan problems, increased performance and
fuel economy.
The cons are a higher cost, and depending on the emissions situation
where you live, if a visual inspection is required, there might be a
problem passing the visual portion of the emissions test.
Regarding the cost, be aware of the little "extras" which can add up.
The manifold itself is around 60-75% of your total expense. The 2bbl
(P5007398 for '92-95 or P5007852 for '96+) is around $330 and the
4bbl (P5249816) is about $240. Don't forget to add in the cost of an
installation kit; Mopar makes one for the 2bbl (P5007638) which is
about $60. Mopar does not have a 4bbl installation kit so you will
need to fabricate it yourself or purchase an aftermarket one, such
as the one I make at steigerperformance.com (shameless plug) ;-)
Figure on $70-90 for that, depending on your truck's model year and
options. You will also need an intake gasket kit (4897383AC) which
is $20-30 (but you would need that even if you were just reinstalling
your stock intake manifold). Since you've got high mileage, plan on
spending the $5-10 on a new bypass hose (H0063735). If your truck is
a 1995 or older, and you are installing the 4bbl intake, you would
need a new exhaust manifold EGR gasket (53010000) ($2) for the blockoff
plate, and if it is a '92-95 and you are installing the 2bbl, you would
also need a new intake manifold EGR gasket (sorry, I don't have a part
number on this one, I think its a few dollars). You can probably
re-use your throttle body gasket, but if not a new one is only $2
(53030541). If you are installing the 2bbl, I believe your current
thermostat and thermostat housing will swap right over, but if you are
installing the 4bbl, you will need a new thermostat (about $5-10 at any
parts store) and a thermostat housing (P4286759) which is $10-15. In
either case, plan on spending a few cents on a thermostat gasket.
(All part numbers listed above are Mopar.)
Don't forget the RTV, thread locker, and anti-sieze. ($10-15)
So, all total, you would probably be looking at about $440 to install
the 2bbl and around $385 to install the 4bbl, and about $50 to to
re-install your stock intake. Keep in mind that none of the prices
I have listed include shipping, so plan on that, or tax if you will be
purchasing them locally. Mail order is probably the cheapest route, and
if you can order everything at once from one source you can probably keep
the shipping costs to a minimum. (You will still need to go to the
parts store for RTV, the thermostat, etc.) Also, the prices listed
were about what you could expect to pay from a retailer; if you find
a used intake on e-bay or something, you can obviously do it for less.
An optional step, with whichever intake you install would be to
hit it with some clear, high temp spray paint to ward off corrosion
and keep it looking nice.
I may have overlooked a couple of items (like assuming that you
have access to a torque wrench) but that should give you a decent
idea of what is involved. I hope it helps!
