1999 Honda Civic Vacuum leak

Hi there,

If you have all these problems you should do the serious one first and that is the low comps, what you will need to do is re set the valve clearances, and do a comp test, if you have a low comp re do the test with a small amount of engine oil in the cylinder as this will temp seal the rings, and if the comps come up the rings are a problem if not you will have a valve problem, start here and report back your findings.
