replace head gasket
My 2001 Nissan Sentra GXE has a blown head gasket. My mechanic is quoting me $700 for labor plus parts (total in the $1200 range). Based on his hourly rate of $90 per hour, he must be planning on about 8 hours. Of course that's for an experienced professional. I'm sure if I were to do it myself (assuming I had the ability) it would take much longer.
you go to a Machanic.
If it was removed then YES.
