Leak in windshield caused electrical failure

ANSWER : At this point, make sure you have careful documentation of your experiences with the car, dates, names and all paperwork from dealer repairs, etc. Check work done at the dealer if at all possible when the car is returned to you so that any residual problems are caught before you take the car back. Stay in touch while the dealer has your car so that it is repaired promptly. Since there is no Recall or Service bulletin for this work, it may not be a revenue-generating piece of work for the dealer, and so it will not be a priority. In the worst case, make yourself familiar with "Lemon Law" criteria in your state, should that path be necessary.

ANSWER : Hi, thanks for writing in. Timing change themselves cannot cause an oil leak but the timing chain cover can cause an oil leak. In order to replace the timing cover gasket, you will have to remove the serpentine belt and anything that has belt driven. This includes the alternator power steering pump air conditioning compressor and crankshaft pulley as well as the water pump. Once all of this is remove the timing cover can be removed and the gasket can be replaced. I would strongly recommend having this job performed by a professional as many parts are required to be removed in order to even access the timing cover. Here at YourMechanic, we can have a technician come to your home or office to perform this replacement for you.

ANSWER : Stop leak products are generally an amateur, unprofessional solution to a TECHNICAL problem. Factory Service Manuals do NOT recommend or specify stop leak products BECAUSE such products are NOT considered to be an acceptable repair strategy, save for rare exceptions. The composition of your question clearly indicates that you understand that the OPTIMAL solution is to just fix the gasket(s) and you are simply seeking a stop gap (no pun intended) measure while you prepare for that repair. After having researched these products for decades and having tried a few, talked to manufacturers and so forth, I would suggest that you just let the vehicle leak until it was repaired assuming of course that oil is NOT leaking onto a hot manifold thus creating fire and health hazards. Of course, it is best to just simply prioritize the repair and one possibility insofar as the cost, as well as the diagnosis, is to get a second opinion from YourMechanic.

ANSWER : Stop leak in the cooling system is likely to cause more problems than it will solve. Modern cooling systems are much more finely drawn and have far smaller passages than older cars, and stop leak will jam things up. I can’t think how it would make your car go into limp home mode however, unless it was a coolant level fault.Of course a code read is in order and that should tell the story. Meanwhile, it’s clear that you need to take care of that water pump problem It may appear to be fixed, but the leak will be back. If you want some help with this, you can Contact Your Mechanic. They can send a technician to your home or office who can read the codes on your Jaguar and tell you what this limp home thing is all about.

ANSWER : If the oil filter housing is integral to the oil cooler, or the housing had to be removed to service the cooler, a professional mechanic with knowledge of the limited service life of rubber seals would have absolutely (guaranteed) replaced the filter housing gasket that you are now belatedly finding leaks. However, if the leaking gasket is in an assembly that was not touched, or is not part of the cooler, they might be on reasonable grounds to have not fooled with it. These cooler configurations vary (from Mercedes Benz model to model) so, having the advice I just gave, you can just simply ask them what configuration you have and go from there. The bottom line is, if indeed, the gasket that is presently leaking was "right in front of them" while they did the warranty work, it should have been replaced simply as a matter of course. Indeed, the weak link on modern engines has become gaskets and seals. The engine will mechanically far outlast the gasket and seals but the problem is to replace all of them (once they all leak) you have to literally take the engine out of the car and take it apart just to put all new seals in. Please let us know how we can help further on this issue.

ANSWER : Hi Ricardo. We answered your question earlier. However, if you didn’t receive the reply, here is what we stated earlier. In most cases, an EVAP leak will create an OBD-II trouble code. The best way to detect an EVAP leak is by having a professional mobile mechanic complete a check engine light inspection, they will be able to download the code and determine the source of the leak. That’s the best advice we can offer you. Thanks.

ANSWER : Most older cars have oil leaks. Sealing technology has just not kept up with mechanical improvements to engines so much so that leaks often kill engines rather than mechanical problems. So, it is not unexpected at all to have an, indeed many, oil leaks on a 23 year old car. Oil leaks vary hugely in terms of severity and priority of repair. Oil leaking onto a hot engine manifold is the worst case (the oil can start a fire; at best, you are left breathing oil fumes in the cabin, as the oil burns off of the manifold) while de minimus seepage of oil at the oil drain plug or oil pan gasket, while annoying and messy, if limited enough is not an emergency. Some leaks are easy to repair, while others literally require the engine to be removed just to get physical access to all the leak points. In your circumstance, if you smell burning oil, oil is probably leaking onto a hot engine part such as the exhaust manifold. A certified Mechanic, dispatched by YourMechanic right to your location, can perform an oil leak diagnostic and then let you know of your repair options and costs.

As far as the check engine light, that is not related to the oil leak(s). If you request a check engine light diagnostic, a certified mechanic from YourMechanic would use a code scanner to retrieve the specific diagnostic trouble code(s) from your car’s PCM that have caused the check engine light to illuminate. Using those codes, the appropriate individual vehicle components or sub-systems (often a sensor, circuit, and the like) are then carefully tested, based on specifications set forth in your car’s Factory Service Manual, to pinpoint the cause of the fault or the reason why the check engine light has illuminated. Once the faulty part or component is identified, it is explained to your satisfaction and the mechanic will let you know of the cost to repair. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.

ANSWER : Hi there. The first thing that any mechanic would do is determine where the oil leak is coming from before quoting you a maximum price estimate. In general, most oil leaks are caused by front crankshaft seals that become worn out, especially on vehicles that are nearly 20 years old. This type of replacement could cost up to $800 to $1,200 depending on what else might be damaged. You might want to have a professional mechanic come to your location to complete a car is leaking oil inspection, so they can pinpoint the source and recommend repairs.
