On a 1998 dodge stratus 2.4 ltr engine misfire

Not really. unless the head was cracked. Blow back is from bad piston rings.

coolant is getting into the engines combustion chamber it sounds like to me. a cooling system pressure test will confirm that but almost certainly you have a bad head gasket or cracked head

1000-1500 dollars for a regular shop.

look around for a better price

probably by the fresh air hose the one that hooks to the throttle body.

it will definitely affect the selling price, a valve job on a 3 liter engine is not cheap.

need to have the head gaskets replaced and have the head/s checked for cracks

For 2004 Dodge Stratus 2.4L SFI SOHC 4cyl the Head Bolt Torque sequence
------------ | 10 6 2 3 7 | | 9 5 1 4 8 | ------------

Step: 1 - Torque to 25 ft/lbs
Steps: 2 - Torque to 50 ft/lbs
Steps: 3 - Torque to 50 ft/lbs
Steps: 4 - Turn 90 degreesRecheck final torque in sequence

Caution:Engine uses torque to yield head bolts (TTY) that permanently stretch during initial installation. New head bolts must be used when cylinder headis replaced or re installed to obtain proper torque specification.

Hope helps (remember comment and rated this).

When you say new engine I have to assume we are talking a manufactured short block engine. Here is a list price of just such an engine:
CHRYSL 2 122 4 C 2000-01 Neon, Stratus, Breeze,FWD,SOHC, MFl, 16 Valve,upper blk #642,651,lower blk #769,head #737,crank #755,valve cover has 10-6mm bolts, extra 8mm bolt under #2 &#3 intake port,with water pump Head part # call DD91 $1,990
Here is a page you should view for brand new engines as a comparison.

If your going to get a manufactured short block engine replacement, and an engine computer along with a new battery AND labor you are getting a fair price.

Thanks for using FixYa.

It usually helps to provide which engine you have and the 8th VIN digit. The valve is located in the cyl head, towards the rear of the head, left side.

hi, it could be down to damaged piston rings, cracked block, cracked liners, but it could also be something simple like blown head gasket if i were you i would get second oppinion as engine replacement is last resort.
