Quietening down a 1.6td
« on: November 10, 2010, 02:46:44 pm »
I have a Golf Mk2 GTD 1.6td, I love the car to bits however the noise of the engine is a bit loud.

Im just wondering if anyone has any tips or tricks I can use to help reduce the clattery noise of the engine.

I realise its not possible to turn it into a modern sounding diesel, but just thought someone may have a way of reducing it in some way.

Thanks

1) Retard slightly.
2) Get some nozzles that presquirt.
3) Reduce injector atomisation, by lowering break pressures.

1. Increase stereo volume.

As mentioned, the timing affects the sound of the engine so at least make sure the timing is within specs. There are all sorts of products to reduce the amount of ambient noise coming into the passenger compartment, car audio places often have these, they are usually painted on or are adhesive-backed pads.

I noticed once that my engine was significantly quieter while driving on a very wet road... I think this was largely due to sound not being able to deflect off of the ground as well. Since then I've been thinking about making basically a skid plate to keep engine noise down. Apparently the TDI's have something like that... maybe worth looking into and trying out? I'll probably try it on my car eventually, but it'll be a while. Maybe you could make one and let me know how well it works? :D

enough boost is when you have 3 dimple marks in the hood from the valve cover nuts..  ;D

Driving on snow is therapy for the ears. The original sound deadening under the motor is often lost/removed. Try that as a first step. Then Dynamat the whole car ;)

Go look at a mk3/4 tdi & see how much insulation / sound deadening material is both on the hood and under the engine.

Can you run 2 stage aaz injectors in a 1.6? I always thought my aaz was reasonable once warmed up.

Yes but they are taller, so you would have to deal with the hardlines somehow. Maybe try AAZ hardlines but I think the pump sticks out further back so they may not line up either.

Yeah, they come with 7-10 things like that.
Burning veg seems to run a tad quieter, and  injector nozzle condition is also a factor.
