check your drive way for oil leaks....

then stand behind your car and let someone start it in the moring...
first start up.... (does it have a little smoke on start up)

this means valve guide seals..

look at your engine is there oil seeping out the head gasket...

check the water is there oil in the water...


now if your car needs valve guide seals it is possible to do these with the head still on for about 50 bucks.... it will take you a saturday and you will have to do some studying....
