Let you motor cool down completly 100%. Should not take long in weather like we have today.
If you can put your hand around the area where the bolt is broken, have someone start the engine. At this point you should be able to feel the air escapeing around the broken bolt on the exhaust manafold.
If you feel the air escapeing thats your problem. It will tick with each gush of air.
Ok so have been doing some more digging on what everyone has said. I looked into the exhaust manifold has a broken bolt with no nut at all. Anybody have experience with this to know if that could be causing my noise? Thanks again for everyone's responses.
Bingo, you probably found the problem. Just the matter of getting it repaired. Broken studs are one thing, but if you or the technician are doing the repair make sure you run a straight edge against the mating surface of the exhaust manifold and cylinder head. With a stud or two broken off and not holding its own the manifold could be warped, and just putting new studs in may not totally cure your problem. You can have an exhaust manifold re-surfaced.
Did you ever get a response from the mechanic? You had said that you were going to bring it in to see what the problem is. I am about to do the same. My fear is that it's a lifter and will need major engine work done. I was just wondering if you had gotten anywhere with your mechanic...
Well not good news! We took out the spark plugs and cylinder 4 & 5 are shoot. Spark plugs full of oil. Cylinder walls not repairable to deep of gashes. Now the question? Does anyone have a good place to buy a rebuilt or low mileage 2000 V10 engine?
I just took my Ex into the shop this afternoon. At first glance they said instantly that it sounds like bad, loose or sticking lifters. This past weekend I put about 2 quarts of Rislone in with my Engine Oil, but didn't see a difference. I also pulled off the driver side valve cover and realized that the lifters are not directly under the valve cover like I originally thought, so it looks like getting to the lifters is not very easy. The mechanic shop is going to look at it closer in the morning and try to verify that the noise is a lifter problem. They told me that if it is the lifters it is not worth fixing because the labor is too expensive to reach the lifters. Is this true? I agree it doesn't look easy but can it really be that difficult that they would say that I would be better off replacing the entire engine? I like to do things on my own, but am not exactly a mechanic. Is this something that someone who is inexperienced but desparate can handle? Any help would be greatly appreciated...
Ok...the mechanic is now telling me that my problem is not a lifter. He is saying that it's my timing chain tensioners and the sound is the result of the chain being slack. When I pulled the drivers side valve cover off it appeared to me that the chain was as tight as could be. Would I be able to easily tell if the chain was loose or not? He is telling me that to change the whole timing chain assembly would cost about $1,500 or I could change just the two tensioners for about $900. I had no idea that this would ever really have to be changed... Any thoughts or ideas???
