engine head will not come off
#21
Hi rs200evo
If the head was stuck that bad then it is almost guaranteed the head studs will be shot and need replacing. When I rebuilt my engine in 1992/3 I got a friend of mine to make up a tap with a very long shank so I could clear out the tapped holes. However to do this properly, you really do need to remove all the core plugs and flush out the block. When this has been done, you should vacuum out, (using a small diameter tube) each stud hole before final clearance with your special tap tool. Use some grease to ensure the crud sticks onto it and is removed. Making sure the coolant passages are clear, and the stud holes clear is not a job to be rushed.
