doesn't sound the way it used to
I'm posting this message as a last ditch effort before having to pay full
blown shop prices. Given the fact that a mechanic won't even look at a car anymore for less than a few hundred bucks I'd rather deal with the grease and broken knuckles if I could just figure out what I had to do. My 89 lebaron w\2.5Lturbo quit a few days ago and won't start again. I don't know how many people reading this may or may not have experienced what it's like to have his\her car die and then, upon turning the key in the ignition, the engine "CRANKS" (NOT START OR RUN) over, sounding differently than it had all it's life. And by different I don't mean low battery or dragging starter kind of different, I mean the sound where you think to yourself "oh sh__, my timing belt has broken or slipped". That's the kind of sickly sound my engine makes now when cranking it over. And basically that's the best starting point I have to work with right now. ALL OTHER SUSPECTS have been checked and cleared. Gas, spark, battery, etc. It's obvious that the bottom half of the engine isn't jiving with the top half but I can't figure out how or why. I've checked the belt and re-checked the belt and checked TDC with corresponding mark and then did it over again with no results. Any ideas about what to do next? Faulty sensor? The top half of chrysler's 2.5L engine is designed to never bump heads with the bottom half which I'm thankful for, yet is it likely that a valve may be otherwise damaged? Thanks for any input. |

When you checked the marks for cam and crank, did you go the next step and remove the distributor cap and make sure its at number one cylinder? |

From your description it sounds like the timing belt broke. When was it
last changed? Have you looked under the cover "marks89lebaron" > wrote in message lkaboutautos.com... > My 89 lebaron w\2.5Lturbo quit a few days ago and won't start again.

I checked the timing by bringing #1 to TDC on the compression stroke and
then verifying that the cam-gears' identifying mark (notch or whatever its called) was in the center of the little open window on the timing belt cover. I did have a little trouble getting the jist of exactly where TDC was. I used a wooden dowel to find the pistons' top height (I suppose everyone does) but I have a hard time gauging the exact center of where the piston-ends its stroke and begins the journey back down again, as there is about a 1/4" (one tooth worth) of play where the dowel sits level. It's hard to decide if the belt jumped one tooth or if its' at home. Sound stupid? This whole thing has made me stupid. Maybe I'll just buy a moped. |

You might pull all the plugs and then verify that each cylinder "sucks
and blows" when you crank it over. That's the way we diagnosed the problem in my sons 83 Chrysler E Class, 4 cylinder when it broke a rod. eldred |

Try a compression tester before you do anything more. If the compression is
okay, then your noise, whatever it is, is happening outside the confines of block/heads. You could have a huge intake leak, for instance. Maybe it sucked in a mouthful of gasket!
