[QUOTE="jarance, post: 224530, member: 21"] Just run the engine and open the radiator cap when it is cold. Check whether there is air bubbles coming out when you rev the engine. If there are sign of bubbles or oil film in the radiator, then your cylinder head is either cracked or wraped. BTW, did you fill the radiator immediately when the overheating ocurred. You should always allow the engine to cool down for about 1 hour or so before pouring cold water. This will prevent the wraping. Getting a new engine is a good idea but it will be a costly affair. You can get a engine kosong for about RM1500 to RM1800. This depends on the CC and age. It also depend on your luck as well as you do not know how much the engine was utilised prior to being scrapped. You also have to consider to change the timing belt (if using belt) and other bearing and tensioner. The cost for labour is another seperate cost that you will considered. Doing a top overhaul would be a better option if the cranshaft, lifter etc are in good condition. The mechanic would be able to determine whether the cylinder head is warp or the gasket is blown. If you change the engine, you will have to re-register the new engine at JPJ or else you will not be able to sell your car later. Hence, make SURE that you can get an AP certificate when you buy a new engine. [/QUOTE]
