Hi, My husband and I have a 1995 Trooper with two leaks; one in the valve cover gasket and one in the seal. I got an estimate to repair these for around $300. My husband is leary because he thinks that once we replace engine parts the car may be damaged or other things may go wrong. Aside from the fact that I mentioned to mechanic that we didn't want to spend alot of money, since our neighbor has agreed to buy it as long as we repair the oil leaks. Does anyone have any knowledge of whether it's okay to replace these parts?
