Guest username Posted June 10, 2016 Share Posted June 10, 2016 (edited) Before going to the trouble of a whole engine swap, try to find exactly why you lost that cylinder. have you done an actual compression test? if not that's the first thing & post up results. Also, if you have any low readings on the first test, drop about a teaspoon full of oil down the plug hole and test again (wet test). if things improve significantly then it points to rings/bores. If the car has stood for a while or missed a service it could be as simple as a sticky valve/lifter or piston ring (or maybe even oil from stem seals fouling up a spark plug), a lot of easier and quicker things to sort than swapping the engine anyway first things first, let's have a butchers at your dry & wet comp test results please Edited June 10, 2016 by username Quote Link to comment Share on other sites More sharing options...
