Question about Mitsubishi Lancer
Hi, first of all you need to double check the timing is correct. once you have done this the next thing for you to get done is a compression test, you can buy these from most car spares shops and what this does is it goes in place of a spark plug then you turn the engine over and then it gives you a compression reading, if this reading is then low this would indicate problem with the head.
One thing to make sure you did is to replace all the head bolts with new head bolts as the old ones will stretch these should be replaced every time the heads are removed, also gaskets should never be used twice so if the heads have to come back off then make sure you buy new gaskets.
did you torque the head bolts up to the correct settings as stated in the repair manual not doing this will result in bad seal at head gasket and this will cause the problem you are having.
The next thing i would do is get hold of a compression testing kit and test each chamber for the compression make sure the car cant start by removing the leads from the coil you dont want the engine starting whilst doing this test. once you have done this test you will then have a good idea if the head is at fault or something else, if the compression is good then this points towards another problem such as timing.
get the compression test done and let me know what the results are, without getting this done you could waste your time stripping the car down for nothing so the compression test will tell you 2 things it will tell you either the compression is good and nothing to worry about or it could tell you compression is low and the heads need skimming or the pistons need checking, the valves hitting the pistons could have damaged the rings or split a piston so the compression test would be the next thing any mechanic will do.
have you checked the timing is correct on the bottom pulley you will sometimes have 2 timing marks one is a mark for top dead center and their is usually another mark for lining the timing up now the tdc mark is not the timing mark you need to use this is the timing mark for the strobe light when adjusting the timing electronically, so double check you dont have 2 timing marks not all models did but its worth double checking.
let me know what work you have done and if you have replaced the head bolts as these will have strecthed and would be scrap also make sure the torque settings have been done correctly for the head bolts and did you make sure any signs of the old gasket was removed. let me know then i can assist you further also get compression test done as this will give you a good idea of the problem your having and it will save you loads of time taking the engine apart without knowing if its a compression problem or something un-related
let me know how you get on or if you need further assistance ok
