Hi,
I bought a 89 Prelude with seized engine. I checked the oil and its seam to be mixed with coolant. The timing belt is in place and its looks in good conditions. I am not sure what to do with it? The engine has only 120.000KM original millage. Is it better to change the whole engine or try fixing this one? If I remove the oil panel, can this help identify the reason for the engine get seized?
I am more inclined into fixing the engine because I am not sure I will get another one with low millage.
Please advise.

The labour for fixing might be more than swaping the engine but I have to buy the new engine which could be from $500 to $1500. The total might be the same
