Rear intake manifold leak is very common on higher mileage LT1's.93-94 lt1's did not have a vented optispark so that makes those models a little more suseptable to break down.If the car you buy is a 94,you can replace it with a 95-97 Optispark which is vented and will allow for some water drainage if water gets in there.Don't pressure wash the motor because of the opti.If you do and it runs sh!tty let it dry for a day thats the only way fix the wet opti.
1.Intake manifold leak--look for wetness front and back sides.
2.Optispark--if you really like a particular model have the pcm scanned
for codes.This will also let you know any other codes that might be
on!
3.Try to purchase one that has not had any performance modifications
done to it.
A.Stock cars are prolly better buys than modded ones' due to abuse,
hard driving,etc...but remember you are buying a sports car so
they've all been driven hard at some point.
B.It is way more fun to purchase and install performance parts yourself
A little self gratification and you will learn more and more about your
car first hand
4.Have fun and look around til you find the best deal with the options
you want.Make sure the car has not been previously in a car accident.
Use carfax,very good piece of mind!
5.Good Luck with your move and have fun with your Z!
