Buick Lucerne Problem Report
Buick Lucerne Oil Leak From Lower Engine Area
The engine may develop an oil leak from the lower crankcase portion of the engine block. Our technicians tell us that the engine must be removed from the vehicle to properly repair this oil leak.
I notice the oil leaking on my garage floor I cleaned it up a few days later it was back again is this a costly repair. - javair
small oil leak from engine. Aged out of warranty. Repair tech tells me "oil is cheap!", meaning that I don't want to spend the money it would cost to repair the problem. Very irritated with Buick, especially since this engine has been around for years. - Visitor
Purchased used in 2012 @ 66000 miles. Now at 106000mi I noticed light smoke from under the hood. Noticed a pin hole leak (coolant) in one of the hoses leading into the engine. Took it to shop for repair, mechanic noticed oil leaking from rear main real. Also in addition to pin hole coolant leak the water pump and lower intake was leaking and the thermostat is bad. The front engine and top strut engine mounts were needing replacement anyway, but since the rear main seal work will require removing the transmission I am having all 4 mounts replaced (front, rear, trans, top strut) because i have seen many comments about issues with them. Also Tech advised on having oil pan dropped to replace gasket since the transmission will already be out of the way. All together $4100 with no warranty. (Included in that price I also got all new tire pressure sensors, Nitrogen Tire fill, tire rotation Work being done: rear main seal, all engine/trans mounts, water pump, thermostat, lower intake hose, oil pan gasket, oil drain plug and seal, oil/trans/coolant flush - Visitor
Oil leak is small, constant irritation. I have decided to live with it, as others have done the engine removal/gasket replacement, only to have leak reappear. - Visitor
Not yet fixed. - Visitor
crankcase seal needs replacement. Buick says pull engine and repair (likely also do spark plugs and water pump for parts only). Cost $2860.00 - Visitor
my mechanic says they all do that. at least $2500 to fix 24hours of labor to remove engine and trans split motor and replace seal...he says if you're going to fix this best to change all gaskets AC compressor and other acsessories because thats the only way to get at and change those too. - Visitor
I went in for a tire repair and was told that they found a leak in the crankcase. It was a massive job that took several days to fix. It was very expensive. I was told it was out of warranty. I thought that modern cars were built better now. - Visitor
