    To swap or rebuild 97 protege engine?? That is the question!

    My favorite rig so far has been my 97 protege. I am currently driving it and would love to keep driving it. I had so many plans for it when I first bought it. It only has about 193 thousand something miles on it.

    However I have a cylinder one misfire that has become the bane of my existence. I have narrowed it down to being a leaky cylinder. Not sure what is causing the loss of compression but it only reaches about 70psi. Which as far as my knowledge goes, is bad!


    UPDATE: Had a compression/leakdown test done. Apparently its something to do with the intake valve. Either not seating or is damaged. They say they may be able to just adjust it and viola. But if they're not able to adjust it then a valve job is in order.

    Can the valves be adjusted on these rigs?

      how is the oil consumption on it?? usually low compression numbers stem from valve issues. a simple refresh of the cylinder head does absolute wonders.

          Turns out all it really needed was just an adjustment on the intake valves in that first cylinder. They put a shim on and she runs like a dream now!
