Exhaust manifold leak gaskets
The right hand side of the exhaust manifold is leaking in my P30. I can’t stand the noise it makes. I put in a new manifold gasket, but now it leaks even more. Do these warp? Is there such a thing as gasket material or cement that will help seal the leaks? Do you know or have any ideas?
Experienced mechanics share their insights in answering this question :
The heat generated by this engine at the higher power levels required to haul these rigs around causes much more expansion and movement of the exhaust manifold relative to the block. The manifold expands, and either cracks, or warps, and leaks around the gasket. Having the manifold machined flat, and using a gasket sealer that "moves" with expansion and contraction is one solution. There are also multi-piece aftermarket exhaust manifold solutions that alleged are also a solid solution.

Spray penetrating oil on the exhaust manifold bolts. Underneath, spray the bolts connecting the exhaust manifold collector to the exhaust pipe flange. Let all bolts soak for 10 minutes. Using a ratchet or a wrench, slowly apply pressure to the exhaust manifold bolts.
If the exhaust manifold gasket fails, the exhaust leak can result in engine performance issues such as a decrease in power, acceleration, and even fuel efficiency. The performance decrease may be minor at first, but will worsen over time if not addressed.
What does an exhaust manifold gasket do? As mentioned, the gasket connects the manifold to the cylinder head. In turn, this allows the manifold itself to collect the waste gases and redirect them to the exhaust pipe while simultaneously pulling in new air into the vacuum that`s created by the exiting gas.
CRC MANISEAL EXHAUST CEMENT Seals off leaks that can come from the exhaust system at the manifold, the manifold flange and gasket, or ends of the muffler, that are drawn into the car by its motion.
K-Seal can permanently repair a cracked or leaking intake manifold which can cause engine overheating.
If you think you have an exhaust leak, it`s best to get it looked at and repaired as soon as possible. If left unresolved, it will dramatically hinder the overall performance of your car. Over time, it can also lead to major damage in the engine and other important automotive systems.
As car repairs go, a leak in the exhaust manifold gasket is relatively easy to repair. The first thing you should do if you suspect you have a faulty exhaust manifold gasket is to pop the hood of your car.
One tell-tale symptom of an exhaust manifold that needs to be replaced, is a ticking noise in the engine. An exhaust leak in the manifold can cause a ticking sound much like hearing a musician`s metronome, especially when the engine is cold.
The only way an exhaust leak can cause a rough idle is if the leak was in a place where it could enter the air intake system.
To ensure these technologies work in the way they were designed to, these intake manifold gaskets must be installed on a clean, dry surface with no additional sealants used.
Sealing Intake Manifold Gaskets. There are a couple of different sealers we like to use when doing this kind of work. To hold the intake gaskets in place on the head, we like Edelbrock`s Gasgacinch, which is a simple contact adhesive. For RTV, we like the Permatex Ultra Gray or Optimum Gray.
Epoxy bonds and tapes can also be used to temporarily fix exhaust leaks. However, before applying them, clean and smooth the leaking surfaces. An aluminum patch will toughen the epoxy bonds. Once you are through, wrap the area with exhaust tape.

Exhaust leak coming from the rear manifold exhaust gasket and I was wondering how do you replace the rear manifold exhaust? 2006 Chrysler Town & Country
ANSWER : Hello – most likely, this is an exhaust leak between the exhaust manifold, and the cross-over pipe. Removing the cross-over pipe will be the required process to replace the leaking gasket if this is the source. i recommend a engine noise inspection performed by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, confirm this diagnosis, and give you an accurate assessment of damage and cost estimate for repairs.

New exhaust gasket and manifold, still have exhaust leak.
ANSWER : The trouble with small exhaust leaks is that they always turn into large exhaust leaks. The hot gas leaking past the gasket will eventually burn up the gasket making the leak worse. If not corrected, it will also burn the surface of the exhaust manifold. It rarely goes so far as to burn the cylinder head, but that can happen in extreme cases. To make matters even more complicated. having an exhaust leak also allows air to enter the exhaust stream and messes with the oxygen sensor reading. Mixture too lean trouble codes will follow as the system shifts rich to try to correct. So, if you want to keep this truck, you need to get this fixed. I’m not sure I buy the line about the head being warped enough to prevent the manifold from fitting, maybe you should get a second opinion on this. You can have this done by contacting Your Mechanic. They will send a technician to your home or office to check out your exhaust leak and let you know what can be done about it.

Possible exhaust manifold leak
ANSWER : Hello and thank you for contacting YourMechanic. The exhaust manifold will make a hissing sound or a ticking sound depending on the leak and how many leaks there are. If possible, get a broom stick and put it against the exhaust manifold and put the other end on your ear. Listen for the loud tick or hissing noise that will transfer through the stick if you are unsure where it is coming from. A lot of the time, the donuts that are in a wide pipe that connect to the exhaust manifold will burn through making the same sound. Check the connections to the wide pipe and check all of the exhaust gaskets for leaks. Replace the gaskets that are burned through. It is hard on the exhaust valves to leave a gasket burned on the exhaust manifolds. If you need assistance finding the exhaust leak, then seek out a professional, like one from YourMechanic, to inspect the vehicle and replace the exhaust manifold as necessary.

Exhaust Manifold Hot/Exhaust Leak
ANSWER : Hello. To say that they catalytic converter is good or bad is impossible without having the car here. If the manifold is heating up, and the catalytic convert has failed, you will see bigger signs of failure in the near future. If you do not feel the need to replace the cat right now, and feel you can wait, then you should. A failed cat will result in bad gas mileage, misfires, and even audible clanking noises with certain failures. Have him replace the bad gasket, which can absolutely be the cause of the smell, and proceed from there. You do want to consider what caused the gasket to fail. Being 10 years old its not unheard of for a gasket to go bad, but if the manifold is truly heating up, it will expedite that process. But trust your gut, and if you honestly think the car is running fine, then hold off on replacing the catalytic converter. Get a second opinion on it was well.

I got p0133 after fixing exhaust manifold leak
ANSWER : There is a technical bulletin to reprogram the ECM for the code P0133. The computer calibration would need to be changed by a dealer. If after the reprogramming is completed and the vehicle is driven- if the code returns then we at YourMechanic can replace the O2 sensor at your convenience.

In the Dodge ram 1500 4.7 engine does coolant run through the intake manifold so if that gasket is leaking I could see loss in pow
ANSWER : Hi there. Coolant circulates throughout the engine, including the intake manifold on V-8 Dodge engines, so it is conceivable that a gasket leak might be present. However, in most cases, the gasket damage (specifically head gasket issues) are the end product of the overheating condition and not the cause. If your engine is still running hot, then it is more than likely that you have an obstruction of coolant somewhere in the system – ranging from an air bubble after completing the recent radiator replacement (which is quite common if you didn’t correctly bleed the system), a failure of the heater control valve or even debris clogged in the heater core. I would recommend two things for you at this point. First, purchase a service and repair manual for your 2005 Dodge Ram, so you can review the coolant system diagram and trace the source of your overheating problem. The manual will also provide you with detailed steps on correctly bleeding the coolant system, which might resolve this issue. Second, if you’d like to have a second set of eyes help diagnose your problem, you can set up an overheating inspection by clicking this link.

Exhaust manifold leak. Headers or stock manifold?
ANSWER : The manifolds on this engine warp and would need to be replaced to stop the leak. The manifold studs would also need to be replaced with the newer stainless steel type of studs and nuts. I agree with the muffler shop about the headers. On another note, the headers would be even noisier then the original manifolds. I recommend having a mechanic, such as one from YourMechanic, inspect the leak and replace the manifolds for you if needed.
