No
Yes, if there is internal leak.
Mine is in the timing chain cover gasket. You can find your leak by pressure testing your coolant system.
Check to be sure it isn't the water pump.
You probably need to drop the oil pan down, remove the front cover and replace the cover gasket and main seal.
Cover suspected area with talcum powder or similar substance to try to determine where leak originates Valve cover? Engine Seal? Timing chain cover? Oil filter? Oil sending unit?
the signs of a valve cover leak are oil on the engine oil is the only thing that can leak from a leaky valve cover
Improperly installed gasket, failed crankshaft seal, stripped bolt, warped timing chain cover, dirt or grit between the cover and the block... that's just a few ideas. I wish I could help more.
yes! i have a 99 chevy mailbu v6 and it was spurting out coolant from that exact thing. cost me $400 at garage.
No, but do check at some reputable smaller garages; that seems high.
lI have the same problem, perhaps we could get a better answer than the first one.
do it yourself. parts are cheap, labor is long and hard. that's why its expensive
