hey this is my first post on dodgeforums.com
but i my 98 dodge 1500 5.2 Liter has 250,000 miles on it and i put another engine in it so it may need a tune up. how much would that cost?
and also it always sounds like it is sucking a lot, and i mean a lot of air, its pretty loud (the sucking noise) and it especially does it when you rev the engine. does anybody know what it might be?
thanks

is your air filter connected tight? do you have a aftermarket airfilter?? i can hear air being sucked in pretty good with my k&n air filter

 

mine makes a supercharger sound when its cold, like when u let off gas or give it just a little bit then it goes away after it warms up, thats only in winter though, perhaps there is a vacuum leak?

 

if its all stock i bet its the air cleaner gasket..

 

A bad bearing in the alternator, water pump, etc. could also be mistaken as that type of noise.

 

i used to have a k&n on it then i took it off, now i have a fram
so do you think my filter housing is not tight or what?
its been an oilfield truck since 164,000 miles so who knows
thanks

 

well i have a 99 with a k&n and i was missing the gasket on the housing and i had a really loud sucking noise but it was all the time if it goes away when it warms up its probabley something different as for a tune up if your a do it yourselfer not much call a local parts dealer and ask.

 

Mine makes a sucking/charger type sound too, especially with the 6X9 filter on. Sounds cool.

 

i took the air filter housing off where i could see the throttle body and right behind where the throttle body flappers are, on the back side of the engine i can feel where all the is being sucked where the noise is coming from. when its started it sounds like im getting to much air in the motor and i am running at nearly 100 psi oil pressure. this is another engine i got out of a 94 dodge ram 5.2 Liter
do you think i may need a new throttle body? how much would it cost? is it easy to change out?

I had a bad sucking sound on start up on my ram. It ended up being the plenium cover on the bottom of the intake. These things are totally prone to sucking the gasket in. Go to www.hughesengines.com They have a 1/4" thick aluminum upgrade plate for around $80. Fixed mine right up.
