Two different mechanics did a compression test and show 2 cylinders with low compression, but one mechanic tells me I need a new engine, while the other says I need a valve replacement job. Not quite sure what to do. Also, If I need a new engine, is there a difference between rebuilt vs remanufactured? Thanks in advance!
You also need a leak down test to determine if the rings or the valves. Rebuilt generally means they rebuild your engine. Re-manufactured generally means they get a rebuilt engine from a specialty house and just install it.
