Subject: Re: Smokin' exhaust - the plot thickens.....

White smoke? Is it the exhaust itself that smells or is the odor something you smell in the car?>> I can smell it in the car, but maybe because the windows are open in summer. The white smoke is from the exhaust. Have you had a lot of rain/humidity or used a different gas station than usual?>> I've been going between four star and lead-free without changing anything in the engine. Weather's been hot here in London UK. Try a bottle of the gas additive that takes water out of the gas tank. That could eliminate the white smoke after one or two bottles>> OK - I'll look at that. I had the car MOT tested in Spring and there was a bit of grey smoke then - mechanic said it was all measuring fine on the Krypton machine. Some gas stations have problems with water leaking into the storage tanks. There's a BP station near me I won't use because of all the problems I've had with water in the gas.>> I've changed the tank once or twice - could fill up again and see. If you're smelling burned coolant/additive inside the car, it probably isn't coming from the exhaust unless you've got a hole in the exhaust. The smell is coming from something leaking coolant and dripping on hot parts. The odor comes up through the vents.>> could well be............but note the open window confusion So you may have two problems instead of one. :) If you're smelling burning coolant/additive at the exhaust pipe, it's probably a leaking gasket. >> Arghhh! I smell money...... For a do-it-yourself test: put newspapers under the front of the car and some white paper towels on top of those. With the car running, hold a white paper towel over the end of the exhaust pipe so that the exhaust passes through it. After a few minutes, look at the towels and see what you've got. Water? Oil? Coolant? I've run cars with leaking head gaskets for months without a problem, if circumstances required it. Could do damage, hard to tell. For the last year, I think the Lincoln had more stop leak in it than coolant. BTW, my knowledge of cooling systems comes from 5 years of owning and working on a 1980 Ford Fiesta. Great little car with the cooling system from hell.>> I did put two doses of some gunge into the water system. The mechanic then changed the radiator. There may well be too much pressure from somewhere. >> Thanks for the ongoing ideas! I'll have to do some tests and report back. Busy - have to address a conference on the weekend, so writing speech.
