Leaks from my LX9 G6 with about 116,000 miles on it:
The oil concerns me the most as I rarely drive the 6 yet I had to put 3/4 of a quart in her after less than 1,000 miles. There's oil all over the back of the block dripping down onto the exhaust pipe and there's also oil around the top of the oil pan on the front of the block. The accessory belt hasn't been slinging oil anywhere so I'm assuming the timing belt cover is good...for now.
I previously replaced the oil sending unit (above the starter, below the heads) which was leaking. The gasket which attaches the oil filter mount to the block also appears to be dry/not leaking.
I've had a slow coolant leak for several years. She's passed pressure testing twice. I have to top off the coolant reservoir 2-3 times a year. It's not disconcerting but I'm concerned a trickle today might turn into a gusher on a road trip.
The local shop wanted about $1,500 to replace the gaskets for the rear valve cover and the oil pan. Considering the parts are under $100 I'm doing the work my self.
If I'm replacing the valve cover gaskets and oil pan gaskets what else should I proactively replace while I have this thing partially stripped? Should I proactively replace the gasket for the coolant crossover pipe gasket, timing cover gasket, oil filter adapter gasket, water pump, etc.
If it was your vehicle, what else would you replace while you were replacing the valve cover and oil pan gaskets?
- oil from Rear Valve Cover
- Oil from oil Pan where it meets the block
- Coolant from only lord knows where
