Exhaust manifolds are listed under the Catalytic Converter System section. Makes sure to check the footnotes and what they apply to in the list. The information above (and the screenshot I will include below) I gathered from my wife's 2020 Forester booklet but I'll wager may be the same for your 2017. I would strongly suggest reviewing your warranty booklet included with your vehicle.specifically the CA emissions warranty coverage. The feds also cover other items for 8 / 80k. A leaking exhaust manifold gasket can cause a burned exhaust valve, which can cause exhaust from the combustion chamber to flow the wrong way into the intake manifold. The standard CA emissions warranty is 3 / 50k with some items being covered longer (7 / 70k). An exhaust manifold leak can be very damaging to your engine if it's not taken care of in a timely manner. However, as far as I know, 15 / 150k coverage is only for TZEV vehicles. It was the way he backed off that gave me an indication he knew damn well she shouldn't have been paying for the work.Īnyhow, the CA emissions warranty covers a lot. If your exhaust manifold is leaking, you will detect a distinct stench in the air. ![]() They quickly backed down and agreed to do the work for free. Exhaust manifold leak simply means toxic gases going back inside your vehicle instead of exiting it. Because it had to do with the evap system (was throwing codes because of a switch) I gave them a call and brought up the CA emissions warranty rights. Leaks in the intake manifold are serious if theyre not repaired, they can cause a vehicles engine to fail completely, says Clay Parks, Bars Products vice. It is basically a loose clamp or damaged hose that cannot handle the turbo boost’s pressure. One time I did have a Honda dealer repair my wife's car (girlfriend at the time) after they told her since it was outside the factory warranty she would have to pay. A boost leak is a type of air leak in the intake path just before the engine cylinders. The existing gaskets do not even look that bad so it has me thinking maybe I try tightening without removing and see if I can shut it up.That through a dealer shop? If not, are they offering to do the work for free (somehow seeking reimbursement through SOA themselves)? Or I could bite the bullet and machine the dual carb manifold but this would force the header situation. Another thought is that I have a spare engine with both manifolds that I could remove and have machined in advance. Seems like this is going to snow ball already. Before I go too far here does anybody have any in site as to whether these issues will force me to remove both manifolds in their entirety. I do not have the replacement for these either. Seems like these will get in the way of removing and sliding the new gaskets behind the manifold(s). Numerous ways can help you find the exhaust manifold leak, and some of these are as follows: Finding leak by turning VAC on Finding a leak by using soapy water Finding leak by covering tailpipes with hand Look for black spot in the surrounding because when there is a leak, it will cause the surrounding area to turn black 1. I am happy nothing broke but now I am wondering about the intake and exhaust manifold pilot rings as well. This article will expand your automotive troubleshooting knowledge by outlining three key signs that you may be suffering from a leaky exhaust manifold. This means that I have to break the seal of the intake manifold too in order to sneak the gaskets in as Rusty Ol Toole suggested OR cut them OR remove both manifolds. One sign of an exhaust leak is a loud rumbling noise coming from your vehicle while you are driving. When the gasket fails to perform, you will hear a noise in the exhaust when starting the car. A leak means the system is not properly sealed, affecting the drivability and performance of the car. A year later and another 15K miles and the noise is back again. They found a broken stud on one of the exhaust manifolds. Looking at my replacement gaskets it seems that the intake and exhaust gaskets are 3 parts BUT each has the ports for the intake and exhaust integral. The manifold gasket is responsible for sealing the whole exhaust system. Took it to the dealer who said it was an exhaust leak. One stud was already busted at the front of the engine so I may have to do an extraction here. Update: Weather here near Chicago has been dismal so I have not been driving.so I soaked the nuts/studs with PB blaster and have managed to get them all to crack loose without breaking them.
