Windshield wiper module

Hello, I did multiple searches on this site for the above subject and did not find one single post on a qx4 valve cover gasket so thought I would ask. Although I did find a few leaking valve cover threads. Here is the history. 2000 Qx4 bought in 2003 with 52000 miles, now have owned it almost 5 years, have 134000 miles on it. All maintenance done regularly including latest, timing belt, water pump, belts, hoses, transmission fluid, rear end, etc., fuel filter, etc, all done at 105000 miles by dealer. Runs great and doesn't burn a lick of oil. Anyway it has begun to cost me some money, had the dealer replace both cv joint boots, intake manifold gasket, A/C compressor, to name a few. All of this in the last 30000 miles or so since the 105000 service. Oil is also changed every 3000 miles since I have owned it with whatever dino the dealer is using at the time. Now I go out and notice a drop of oil on the ground only when the vehicle has been driven and then parked. If it is parked and I get underneath and wipe the oil, it doesn't drip by the next morning, only when it is driven and then parked, it will produce 1 or 2 drops in a few hours and then that's it. While underneath I saw the drip was dripping off right where the transmission meets the engine. I thought is might be the rear main. But I started looking above and saw the valve cover gasket was leaking and I believe it is running down and coming out at the point it drips on the ground. This is the left side if you are standing outside facing the engine or the right side if you are sitting in the vehicle. It is the side that appears to be real easy to get off as oppossed to the other side which looks like it is buried under the intake, etc., looks like a lot of labor to get to it but that side is not leaking. So the gasket is 13 bucks online and I am sure my dealer will want hundreds of dollars to change this. I have sort of gotten to the point that I am tired of forking over 3 or 4 hundreds bucks everytime I go to the dealer. Has anyone with limited mechanical experience like me ever attempted this change. Just wondering if it can be done easily. Now I would not attempt the other side, looks too involved but as long as it is not leaking I am not going to touch that side. The side I have leaking looks like there is only 8 bolts and the cover is coming off. Is this correct or is it not as easy as it looks. Also this is the 3.3 that was used in the Pathfinders of this era as well as the Qx4. Any information or comments are welcome. Also if anyone had this done at the dealer please let me know how much you paid. Or if you are an expert what would be fair in your opinion for the dealer to charge just to change this one side. Thanks again Sammy

I have a 1999 GMC Jimmy LST 4WD 4 door with just over 100,000 miles on it. No trailer and mostly highway miles. No oil use, Mobil 1 changed frequently. It runs great and has no problems. New transmission at 80,000 and all servicing (radiator, transfer case, etc.) up to date. I know I should go into the plugs and wires soon and wonder what else I should do and what cost(ballpark) I should expect. I know parts and labor do cost something and am not interested in being cheap. Because I have had no trouble, I have not had to find a shop to deal with that gives you good information. All I have seen and heard about is places where there are commissions for order writers based on add-ons (at standard individual list price)that are done when they are not needed or are done in the process of doing what they are already doing. My son's friend just quit as a manager of a national tire/repair chain because he could not handle what he was expected and told to do, especially for the poor woman that just came in for an oil change that became over $1500 because of required "suggestions". I need the information to find/evaluate a good local shop I can have some confidence in since, my wife's Blazer is just behind mine with about 75,000 miles on it.
