you mean there is coolant in the oil or oil in the coolant either ways sounds like a head gasket problem.
dohc is better
The engine is an interference engine, if the timing belt breaks or slips it will cause damage to the valves and possibly the pistons.
The 2.4 litre DOHC engine is NOT an interference engine.
It depends. If there is a DOHC engine available that uses the same bottom end as your SOHC engine, then you can use that DOHC head. Just make sure that there are sufficient valve cutouts on the pistons. If there ISN'T a DOHC head available for your block, then a full engine swap would be a better idea. But even if there is, a full engine swap may be a better and more cost-effective option.
No , the DOHC engine is not an interference engine ( but the SOHC is an interference engine ) in a 2002 Dodge Stratus 2.4 liter
Dohc means that the engine has 4 valves per cylinder or 2 camshafts per head :)
DOHC means Double Over-Head Cam. The engine has 2 camshafts that are located within the cylinder head at the top of the engine.
You could have the 2.0 L - DOHC - 4 cylinder or a 2.5 L - DOHC - V6 engine
2.0 dohc turbocharged.
It would have either a 2.0l sohc or a 2.0l dohc. Both are inline four cylinders.It would have either a 2.0l sohc or a 2.0l dohc. Both are inline four cylinders.
