Default Front cover gasket replacement

I have had a coolant leak for awhile now but here recently it has gotten a lot worse so I am going to be replace the front cover gaskets tomorrow and I am wanting to know do yo really half to pull the oil pan because I really don't have the money to buy that gasket because we are also thinking with the noise front the front of the engine it may have a bad timing chain so I need to save a little money to buy that. Also I have already replaced the water pump with a new gasket earlier this year, also I replaced the coolant reservoir along with new bypass hoses and Upper and Lower coolant hoses to when I replace the water pump. Also the engine has had the upper and lower intake gasket replace so I have been able to eliminate almost every thing that maybe causing my coolant leak except the front cover gaskets. So I have come to the conclusion that the front cover gasket it my last I idea to try before I half to suck it up and shop it if it is still leaking coolant after I replace these gaskets. Also I was talking to a few people that has the 3.4 V6'* and the said they didn't half to pull the oil pan to replace these gaskets so I am hoping that is the same with the 3.1 that I have in mine.

The 3.4 and 3.1 are basically the same engine in design. I personally have not seen a front cover leak coolant. I worked at the chevy dealer for 6 years and never saw one. Have you replaced the lower intake gaskets. They are known for leaking. Them and the water pump are the most common leak places.

Sorry i missed that. I just never have seen the front cover leak coolant. According to alldata you have to remove the oil pan. Also the power steering pump, oil filter and adapter, starter, engine to transmission brace, balancer and belt and some other small things. Hope this helps you. Good luck.

I am gonna need all the luck in the world because I have gotten to the point that I can't afford a gallon of coolant every week because that is how bad my leak is so I am hoping by replacing these gaskets it will stop leaking.

Well it was a bad gasket it the front cover, but I also found out the car will need a new timing chain and both gears along with a new dampener. Also it is going to need a new harmonic balancer and a new crank sensor so this project of mine will not be running for a few week now do to the lack of funds to afford the harmonic balancer and the crank sensor. Also I didn't half to pull to oil pan off which made me really happy.

The oil pan gasket sits inside the oil pan so all I half to do it just put a bead of RTV on the timing cover and it will seal itself. Also I noticed that mine had alignment pins which will make it easier to put back together.
