Unhappy bored with my engine fumes TDI. possiblity to change to Gasoline?

Hello Grand Lovers Fans. Actually I have a Defender 110 TDI 300 Model 1997 with 450.000 kms.

Im really bored with the engines fumes because of the Diesel. I have change the injection pump, I have checkef everything according to the engine and the fumes. I would like to know if its possible to do something to reduce the diesel fumes, or maybe to join up a gasoline engine or install gas technology using the actual diesel engine. Note that the Defender is at 2.600 meter above sea level. Thanks

Ensure you have no exhaust leaks and a tail pipe that exits fully to the rear of the vehicle (extending just past body or flush). I have found that when exiting at a 45 degree angle towards the rear corner of the vehicle allows the exhaust to be carried better by the airflow around the body.

If your timing is retarded you can get some really nasty unburnt diesel fumes. If the smoke is whitish then that could be the issue.

Have experienced the same thing and was wondering if a raised tail pipe similar to a big truck would work sufficient enough to send the fumes back behind you, especially at highway speeds.
Not that I ever burn anything other than diesel, cough cough.
When I back up it can be a bitch, otherwise the fumes for the most part are busy smoking out the people behind.

Are you talking about exhaust fumes or the fuel itself?

That's because you burn that nasty fryer oil not diesel. I'd get tired of the smell of fried fish too

Hi Red90. I supuse is the engine and the exhaust fumes, the Diesel in Colombia is getting better since 5 years ago and nowadayswe have many diesel cars from many car brands and they do not shows fumes signals.

I don't have any fumes other than from pulling away uphill from a stop. sure sounds to me like your fuel/timing is off. you shouldn't really see anything driving from a TDI. getting your engine right going to be cheaper than a petrol conversion, that's for sure.

You're going to have to add a lot more descriptive detail on the conditions where you have visible smoke and when you don't.

if you can smell fumes but don't have smoke, then it sounds like an exhaust leak to me.

Dear Mark. Do you think the turbo is maybe one of the reason?

worn injector tips result in incomplete burn and result in considerable smoke. Have you had your injectors checked ? They typically require new tips every 80-90k

not if it's working correctly. do you have a boost gauge? hows your power? you'd hear a boost leak quite easily.

I'd wager a pretty big exhaust leak. My guess is that your truck, in addition to being quite smelly, is also quite loud.

If a seal in the turbo is gone, it can leak into the downpipe, and cause excess smoke. Are you consuming oil?

When I start it up at a rally in the morning to charge the auxiliary battery?
Makes me cough just thinking about it.
How about the people in the next cap downwind?

Thank you everybody ! I appreciate very much your answers to my problem. So, finally what do you mean when you say: Exaust leak or boost leak? The problem comes from which part of the engine? So I can start checking from that point. Thanks

Really, you need to either look over the whole system yourself or have a mechanic do it for you. There are a dozen possible things that could cause these problems. It is a 20 year old car. It needs love.

Rob, you're looking at it the wrong way. You should fire up your diesel in camp every morning to control for Zika and Liberals. Keeps the pests at bay and gives you the freedom to smoke fatties around the campfire at night without any liberals downwind interrupting your scotch with whiney nonsense.

FWIW,
My tdi was leaking like you're description,
Had headgasket leak in back towards bulkhead,
Started small n figured manifold leak, replaced manifold gasket then realized the head was leaking out back.

I wrapped my exhaust with header wrap too the floor pan, helps with heat issues.

Has the fuel pump been tampered with?
