Help 96 SL-2 no compression
Hi all
I have a 1996 Saturn SL2 143,000 miles. Was running fine not a problem. Then Yesterday morning I started it up and the engine had a miss. Ran rough. Figured a wire plug or pack. Drove it over to the local shop. He found 0 compression in the #3 cylinder I mean 0 . Shot some oil in and the compression was still 0. Took the valve cover off all looked fine nothing broken. He is not sure what's wrong at this point. Whole in piston a valve ??? Compression good in other cylindesr. So no bridge between cylinders. Remember the compression gauge did not move. Any Ideas without pulling the head. Thanks Ron |

How would you tell if the valve is stuck and how would
you get it unstuck. The shop had the valve cover off and saw nothing abnormal. On Wed, 25 Oct 2006 20:41:32 GMT, BläBlä .

A broken spring from sitting overnight isn't all that likely either. Much more likely in my opinion is that either (a) the problem actually occurred as the OP was driving home and he didn't notice until the next morning, or (b) whatever broke, broke the moment the engine was cranked. -- Regards, Doug Miller (alphageek at milmac dot com) It's time to throw all their damned tea in the harbor again. |

It turned out to be a piston with a big piece broke off the top of it. Ken |

Misfire?
May I be so ignorant to inquire what a misfire sounds like/ how you know
your engine has done this? My Saturn is my first car. |

I had the code checked, and it was something like "engine misfire". After that, everytime the car started rough, stumbled, and the SES light came on, I figured it just misfired. So all I say, if you hear a stumbling, and see the SES, you might have a misfire. later, tom @ www.NoCostAds.com |
