233k miles na 2004 v70
mobil 1 every 7,500 miles

Had oil leak for the past 2-4k miles, thought it was from the top of the engine, maybe the cap seal. Have not lost much oil, but it is leaking.

In the last week the CEL has come on twice and gone away. It's out now.

Mechanic checked mounts at my request, discovered oil on the passenger side of the engine covering the mount. Mount had failed. He suggested all the seals should be changed. Getting deeper, I asked why they failed. Suggested to me that the motor has lots of miles and worn rings might cause excess crankcase pressure. I don't know if he is preparing me for the worst. I just put a lot of parts into the car. He has a pretty good track record with me. I trust him.

I called my other mechanic friend who has 20+ years at the dealer. He says the way I maintain the car it does not seem likely I would have engine wear. Volvo says they designed the motor for a minimum 250k miles before any failure. I guess I'm close.

Second mechanic said I should check for vacuum at the oil cap. Excess pressure would cause oil to blow past the cap and engine seals. Could be caused by clogged breather, and hopefully not engine wear.

Went to check the cap with the engine at idle. Pressure was not negative.

Is there anyway to check the breather and engine wear? Am I getting the advice I need from my mechanics?
