  1. Problem Reports
    I've got something going on with my Eclipse 4G, and I can't figure out what it is. I'm trying to avoid taking it to a shop and blowing 500% more money than what the repair is worth on mechanics time and repairing parts that aren't the problem. So I thought I'd ask here first. Here's the deal...

    Upon removing my cylinder head to replace a blown head gasket, I was cleaning up the mating surfaces on the head and as I spun it around to get to each surface, these fell out. Two of them fell onto the ground and I was not able to tell exactly where they came from and one was loose inside one...

    Hello there! I'm AJ, out of Maryland, US. Just joined the club with a 2009 Eclipse Spyder GS. I've always had a crush on the Eclipse since I was younger and Fast and the Furious came out. The body style was so sleek and smooth looking. I was elated to see that this 4G was the only car in my...

    Anyone know best spark plug gap size once we start putting performance parts on the GS. Have mine at the .08mm as per the book. But debating on opening them up a little more.

    Hi I've been getting the code P0421 and low gas mileage. First thing I checked was if my spark plugs were fouled up. When I checked them, all my spark plugs had oil. So I replaced the valve cover gasket and spark plug well gasket thinking that might fix the problem. I erased the code and drove...

    Hi, ill start off by saying I just had my water pump and timing belt changed, I don't know if this new problem is related or not. Right before I got that work done I started have trouble getting my car to restart, but only after it had been running for a while. One day about a month after I had...

    Today I replaced the valve gasket cover, spark plug seals, and spark plugs on my 2006 GS due to finding oil in the spark plug wells, and now it won't start. It cranks but nothing else. Any ideas on what this may be?

    In my recent attempt to replace my spark plugs, I put the coil back in and did not use a torque wrench to tighten down the bolt. I broke the head off of the bolt and cannot find a replacement bolt online or instore. Where can I find a replacement?? And would I be correct in assuming i shouldn't...

    So while replacing my spark plugs on my 2006 GS, I discover oil in the tubes :facepalm: After reading up on some very useful threads here, it looks like OEM tube seals are the best way to go. Which is great, except that I can't find the OEM part number! Valve cover gasket part number, no...

    Hello, everyone I have a 2007 Mitsubishi Galant Ralliart and I'm looking to buy headers. I've been riding with the CEL on for months due to O2 sensor in the rear, I did the spark plug fouler mod and it worked for about a week before the CEL came back on. My city MPG has decreased and I've...

    Hello all, new member so please go easy. OK I'll try and not make this long. I was doing 60mph on the freeway and the car just died (2006 gs manual). Turned out my timing belt and I think balance belt snapped. The mechanic sent the head out to be machined. He later reported back that I only...
