1998 1.6 exhaust blowing? - scarpetta
Hi all
I have a S reg Ford Escort 1.6 16v petrol. The car has done 103500 approx miles and I use it as a run around for my work.
Afew months back the exhaust started blowing, I took it to the mechanic who has been looking after my cars for years and after having a good look around the car informed that it was the middle bit of the exhaust that was blowing, it may last alittle longer as it wasn't blowing excessively but would need a new middle exhaust evenually, also the cat converter was falling apart but again it was not determental at the present time but would need sorting out before the next MOT.
Due to lack of funds I was unable to get the work done until now. A new middle exhaust and cat converter have now been fitted, approx 4 days ago. The day after the work had been done the exhaust was sounding like it was blowing again, I rang the garage and they took it back in to double check it but couldn't locate where it was blowing, the mechanic agreed it sounded like the exhaust, he suggested I take to his friend who specialised in exhausts, the friend looked at it throughly but he also could not find a problem (he also checked all the seals), he suggested that sometimes when a new exhaust and cat had been fitted that the emissions could be heard resounding off the hollow pipe until a layer of carbon had built up in the new exhaust pipe hence muffling the noise, what I would like to know is, is this true or is there something else I should be looking at.
many thanks

It is not carbon in the pipe-the muffler filling-usually Basalt wool- is placed in the mufflers in thin plastic bags-to protect the assembler and the environment-these melt when the system get hot and then the filling settles into place.
