My Alero may be dead. Need Advice

[GLS_Jeff]

Hey everyone I have a 2000 GLS with 86k miles and 3 weeks after buying the car came major overheating problems. After replacing the radiator, water pump, thermostat, coolant resivoir, and all hoses it was time to replace the head gasket. I stripped down the intakes and everything else right to the heads and then work got crazy so I decicded to hire a mechanic to finish it. The mechanic claims to know these engines very well and came today to pick up the car. When he came to pick itup he called and said there is oil residue in the intake and he believes its "blow by" which is oil leaking threw the piston rings and he said he will fix the car but he believes it's not worth fixing. I told him to leave the car for now till I consult my expert a.k.a. (you guys). So my question is, does this guy know what he is talking about? have any of you experienced oil residue in your intakes? And is it time to give up? I paid $2000 for this car and have over a grand into it. I really don't want to give up cause I do love this car, but three grand plus into it and I only drove the car like 600 miles. Thanks everyone
