I pulled my truck into dodge and they told me that i blew an intake gasket. does anyone know what it would cost for a new one and how easy it would be to take off the intake manifold to change the gasket. dodge estimated me around 300 or more to put a new gasket on does that sound resonable. thanks.

Cost me somewhere in the 400 hundred range to fix the intake gasket on my old blazer, and that was at the employee rate, so I'd say that's a good price.

 

well i found out that when my truck backfired it blew the intake manifold into pieces. i went to dodge and they showed me the manifold and it was made of plastic does anyone know of an aftermarket one that would be better. new manifold from dodge is 150 then he is doing plugs and wires plugs are 50 for 16 and the wires are 160 is there aftermarket ones of those that i should get as well seeings how they got it all apart. when all said and done its gonna cost 793 plus tax in CDN to get it back together.

 

did your engine light come on when the gasket blew ? Also did you have diagnostics hooked up reading "emmisions leak" or anything of the sort? might have the same problem. been told it was my gas cap but its been replaced and light still comes on. let me know. thanks.

 

When it happened to my 1999 5.9 1500, I found out when I lost all my oil within a week of changing it. I did a vacuum test and verified the problem.

 

the check engine light never came on i turned my key back and forth 3 times and it showed 3 codes p2108 p2172 and p2106. they hooked it up to the diagnostics and it showed a vacuum leak. its not just an intake gasket that blew my intake manifold was broken in two.
