Did a compression and leak down test at JDMYARD today. Compression results were 240 235 230 240. and Leak down test showed all cylinders stable with no major issues. So from this we gathered it was most likely the valve stem seals. So at the moment i am getting quoted on valve stem seal replacements which will pretty much be a major service with timing belt, water pump replacement etc. OR drop in a used motor. What are your opinion guys?
