My car is a 1986 Honda Prelude 2.0 Si with like 180,000 miles on it. When I start driving the car kind of jerks a little and the RPM's go up and down. It also smells like burning oil. I put Mobil clean 5000 in it the other day and thats when it started happening. Also the hood is smoking and the fan under my hood runs long after I turn the car off. I don't know much about cars at all and would like to have someone maybe tell me whats wrong with it.

hi there. read your post and this is my opinion, it could be burning oil because the head gasket is gone/head cracked/hole in a piston etc etc. my advice to you is to go to a garage just to ask for a compression test/head gasket test and possibly a cylinder leakage test if the compression is low but you cannot go too far on a car that has done 180k if it says it is low on compression because it could be very expensive. this will gaurantee if it is the internals of the engine or not. all of these tests at any reasonable garage if you just ask for what i said should charge you about half an hours labour. much more than this is unacceptable because it doesn't take very long. i hate to be the bearer of bad news but 180k is a huge amount of milage for a vehicle like this and im pretty sure you aren't going to like the results of these tests but it is the fastest and most cost efficient way of getting to the conclusion. hope this has been of some use. danny

A diag INCLUDING a comp & leakdown test for .5?????? Danny, book time for a compression test on this vehicle alone is .8
Obviously you don't make your living doing this. There isn't any problem with other folks jumping in and offering advise as long as it's good but please check your facts and make sure it's realistic before you make a post where you are trying to pass yourself off as an expert. As far as going into a shop and asking for specific tests, that can get very expensive, especially if you don't know how to interpret the data. The best & cheapest course would be to go in, tell them the problem you are having and let them decide which tests would be best to perform to track down the problem once they has test driven the car and confirmed the failure.....

There could be a few things going on with your car, Danny kind of jumped to the worst case scenario. The 1st and easiest thing would be to check for oil leaks. Make sure your valve cover gasket isn't leaking on the exhaust manifold. As for the cooling problem, when the car is cold, check your coolant level in the radiator. If its low this can cause it run warm. If it's low then that mean there is a leak......somewhere and that would need to be tracked down. As far as the jerking. You could double check the basics, pull a couple plugs & take the cap off and look at the condition. It could be something as simple as a plug breaking down or wire arching......
It's also possible there could be an internal problem going on, with all the things going on at once with your car that can't be ignored.... If you do decide to take it in......Just tell them the problem you are having and let them tell you the cause. If you take Danny's advise you'll wind up paying a lot of money and possibly not finding your problem..... Also I'm not sure what planet Danny comes from but here on Earth any shop who's techs are trained & tooled properly to find and fix your problem, they will be in 1.0 to 1.5hr range to check your car out.......Anyone charging less than that is more than likely taking shortcuts & guessing a bit.........
