Ok 92 Expo LRV (Mitsubishi) runs perfect - but has an oil leak - lets start with whats been replaced so far New OSU New Distributor Stalk Seal (O-Ring basically) New Valve cover Gaskets (Including Spark Plug Gromets) still leaking Now - I am sure its not the Head Gasket - this car has never over heated - there is no Oil in the coolant, no coolant in the oil either so i am left with guessing its a Rear seal Oil puddles/pools on the left hand side of the motor - one shop said head gasket leak - however I am not over heating, or finding coolant in oil or oil in the coolant -- this cars never ran any hotter then the day I first got it -- question is how accurate of a guess is this - and what does this cost to repair at a shop? rough estimate? and if I go to get it repaired what other seals or parts should I have em repair while they have the motor lifted? Thanks Sangrel

I have a 2000 LeSabre. For several years now, the message center that displays the odometer, and other messages has had a condition in which the connection between the computer and the display seems to have become susceptible to shorting by the humidity in the ambient air. After the A/C has run for a while and removed humidity the problem ends and the display again works, ungarbled. In sub-freezing weather with no moisture, the display seems to work, until it warms, and if long enough for moisture to evaporate, works again. This has been an annoyance, but didn't affect the operation of the car. Recently, the disrupted connection phenomenon seems to now have occured in a connection somewhere between the computer and the cylinders, such that the engine misses during times of moisture. Again, during sub-freezing temperatures the engine runs fine without missing, and as the heat from the engine warms the car, the occasional missing recurs, often causing the check engine light to turn on. In severe occurences the light blinks. The GM dealer wants to simply replace plugs, wires, and coil, which I am confident will accomplish nothing more than drain my bank account. Where can I find the resource to track the problem down in the computer controls and connections to fix it, or someone who can do it for me? Thanks.
