2003 Mitsubishi Eclipse GT: How to Replace Valve Cover Gaskets! 

All the information you need packed into one video! As always, thanks so much for watching and supporting the channel!

Id' recommend doing both front and rear and also the plugs+wires just to get it done and over with if you haven't.

Anytime! I think videos like this are a good resource for 3G owners to save them some time and money. I plan on more tutorial videos like this as the problems come. Thanks for watching and hopefully this will help you when you need to do your valve covers!

Really happy you found this useful! No problem homie!

Glad I could help

Hope this helps homie

Thanks!

It's difficult to determine the exact cause without inspecting the vehicle, but I can offer a few possibilities. I do know that the valve covers on the 6G72 can bend very easily. Firstly, it's important to note that the valve cover gaskets and the head gaskets serve different purposes and are separate components. Valve cover gaskets are responsible for sealing the valve covers to prevent oil leaks, while head gaskets seal the cylinder head to the engine block, ensuring proper compression and preventing coolant and oil from mixing. If you experienced coolant mixing with oil after the head gasket replacement, it's possible that there was an issue with the head gasket installation or another underlying problem that wasn't properly addressed. This could have led to the coolant and oil mixing and potentially causing damage to the engine. Regarding the subsequent loss of coolant and oil, a bent or damaged valve cover might cause oil leaks, leading to oil loss. However, it's unlikely that a bent valve cover alone would result in coolant loss. Coolant loss could indicate another issue, such as a leaking radiator, a faulty water pump, or a cracked engine block, among other possibilities. Whether the shop's previous work is connected to the current issues would require a proper inspection and evaluation by a qualified mechanic. If you suspect that the shop's work might have contributed to the problems, it's worth discussing your concerns with them and giving them an opportunity to address the issue. Ultimately, I would recommend consulting with a trusted mechanic or taking your vehicle to a reputable repair shop for a thorough inspection and diagnosis. They will be able to provide you with accurate information about the specific issues and their potential causes.

@@that3ggt the coolant was probsbly from the initial problem of overheating which would make sense

Patience and persistence go a long way! Noice job

Thanks homie! I believe it is a very similar process for the gts. You may have a few extra connections but it should be relatively the same and the intake plenum bolts should be in the same locations as this manifold. You can check what people say about removing the GTS plenum on CLUB3G forums and see if there is any extra steps you need to take. Hope this helps

I have the GTS. The intake removal is the same. But if you are talking about the plenum, The GTS came with a VICM ( variable Induction Control Manifold) inside the plenum. It is the same to pull out with just a few extra vacume lines and a couple of sensors to remove and disconnect on the passenger side of the plenum that connect to the VICM.

If I end up rebuilding this motor yes I will video the process of replacing head gaskets!

online I like getting parts from RockAuto, in person I'll try the dealer, if not then go to my local auto store.

Hey homie! After several days of driving, the gaskets are not showing signs of a leak. I would like to say yes!

Awesome! Thank you for this video!

Anytime!

"It seems like David Qi is asking a question about installing spark plug wires on his Sebring's engine, which has six cylinders. He is specifically asking about the installation of the spark plug wires for cylinders 1, 3, and 5, which are located on the back side of the engine. David mentions that he noticed the ignition side of the new wires he is installing is marked with odd numbers, with the top wire marked as cylinder 1, the middle wire marked as cylinder 5, and the lower wire marked as cylinder 3. He is concerned that he may have mixed up the wire lengths or sizes during installation, and is wondering if this could cause any problems. In summary, David is asking if using spark plug wires of different sizes or lengths on cylinders 1, 3, and 5, or mixing up the order of the wires during installation, could cause any issues in his Sebring's engine." If that is your question then the short answer yes but the long answer is no. You just need to make sure the distributor terminals have the wires running to the correct cylinders which are labeled and you can find diagrams online. If if not I can go look at my car for reference but it's the winter currently. As long as the wires are for the 6G72 and the connection works you will have no issues. It shouldn't matter what number is on the wire that's just to make it easy if you have a full set like me. My 6 wires had 1-6 labels on them so I just put them in accordingly to the label on the distributor. I obviously matched the numbers because I'm OCD but mechanics will swap spark plug wires all the time when testing for ignition issues so it should be no problem. The only thing you can really mess up and I'm not sure if it would harm the vehicle is if you were to hook the wrong wire up to the wrong distributor terminal. I would assume the car just wouldn't start.

@@that3ggt thanks for the reply! I am able to get the wire replaced and get them right. But I had an problem when I reassemble the air manifold back, I tied the throttle ground wire to the wrong place. Then after it started, it’s shaking idling not right. I changed it to the right location and it fix the issue, but I don’t understand why the grounding can cause problem. Thanks

Glad to hear that you were able to fix the issue by reattaching the throttle ground wire to the correct location. In terms of why the grounding can cause problems, it's important to understand that electronic components in a car are designed to work within a specific range of electrical conditions. The grounding system is a critical part of ensuring that these conditions are met. When a component is not properly grounded, it can cause electrical interference and voltage fluctuations that can disrupt the performance of other components. This can result in symptoms such as rough idling, misfiring, and other issues. In the case of the throttle ground wire, it's possible that the incorrect grounding location caused electrical interference that affected the throttle position sensor or other related components, leading to the rough idling you experienced. Once the ground wire was reattached to the correct location, the interference was eliminated, allowing the throttle system to operate correctly and resolving the issue. It's always important to follow proper wiring and grounding procedures when working on a car to ensure that all components are operating within their designed specifications.

appreciate the feedback, I see what your saying. My thinking was is if someone was outside trying to watch the video on their small phone screen they might want big text. Next time I'm gonna have separate slides with the text and the video of the car so it's easier to see. I just did both at the same time to keep the video shorter.

@@that3ggtyou had a realistic thought and solution I applaud you for that
