the intakes will seep at first then will seep a little more then one day it won't be a seep anymore. it will be a leak which will let coolant in the oil and it will have a fluctuating temp gauge because coolant is not pressurized anymore. the problem will only get proggresively worser until it won't run without running hot risking cracking a head. if it is only the intake gasket seeping you could just get away with a set of intake gaskets.if you do it before it runs hot . the head gaskets are alot tougher to blow. these motors are a pain to work on because of the fact that you have no room under the hood to work. it will probably cost you around $600.00 to get it done in a shop. or if you are mechanically inclind you can get a manual and put the intakes in yourself. the upper gasket set runs about $50.00. but i would get the intakes done pretty quick.
