Mitsubishi Lancer: Loss of engine compression Hi,
I drive a 1999 model petrol Lancer which has done approx. 95,000 km. This car has been in the family, here in Delhi for over 6 years now and has been well maintained and carefully driven, it has done a genuine 37k km in those six years. It was bought used in 2005 with around 58k on the odo.
I recently took the car for an engine scan and a compression test and was shocked to discover that there was serious loss of compression in all 4 cylinders.
The compression figures were around 82-90 psi across all the cylinders!! That's a BIG loss, and the mechanics immediately pronounced the pistons to be bust, but i couldn't figure out how that could happen in just 95k kms. There are no tell-tale signs of engine damage - no blue or white smoke at all, no excessive oil consumption, (in fact, the car has hardly used up any oil in the 7000 km since last service) the spark plugs were fairly clean so I really can't figure out what could really be the reason for the compression loss. The only issues are a low (sometimes unsteady) idling speed and subsequently a slight juddering when first moving on a cold engine, and of course, a noticeable power loss at low revs. There is a slight hissing sort of sound when i lightly rev the engine while moving, and someone suggested that it could be a valve problem, maybe the exhaust valve. All mechanics say the same thing - that the pistons are gone and the engine needs a full overhaul. But that's a big expense and i need to be doubly sure that it's the right diagnosis.
Right now, i'm a fairly stumped.
Anyone ever had a similar problem? Do you think it's definitely the pistons gone kaput, so early? I could really use your thoughts or advice on this problem.
Also if anyone can suggest a good place here in delhi that i can take the car to for a proper check, apart from the HM authorised service centres.
Thanks in advance.. |
