I'm in process of replacing timing chain gasket set but having a challenge getting cover unseating from engine face. I had coolant leak, couldn't figure the source. Thought it may have been 9 year old pump, didn't see any place around weep hole or anywhere around pump. Anyway, decided to replace everything. I would like to remove cover w/o damaging/destroying if possible. Any ideas to assist in this project -- would like get car back on road soon.
