After joining this website I've gained a bit of confidence when talking to mechanics about my 147, and that is thanks to you guys.
When i took my car in for changing of the cam belt, my mechanic told me that my exhaust is "blowing". Not knowing what that meant i decided to get a send and third opinion. These are the opinions i received in chronological order.
They opened the hood and placed the car on the ramp and listened while revving and suggested that i install a new "branch" and that is going to cost me about GBP 125. And they said it was cracked.
I then called the guy that diagnosed the exhaust as being "blown". He said i should bring the car in and he will remove the manifold and send it away for welding the "crack". And that was going to cost me his labor and and another cost for the welding totaling GBP 42.
My backup mechanic:
He also "listened" to the revving and also diagnosed the "crack" and would do the same as my backup. Unfortunately he was too "busy" to get back to me with the pricing.
Exhaust specialist 2:
With the above info/knowledge i went to see another exhaust specialist who i told from the outset that "my exhaust manifold is cracked, and i need to weld the crack" i told him that my reasoning was that i don't want to take it to my mechanic who was only going to send the manifold back to them for welding thus i pay double. He was kind enough to go the extra step of actually removing the "heat shield" and trying to locate the crack.
What he and i observed was that there was no "crack" as such on the manifold. What has happened is that where the rightmost manifold "pipe" connects to the manifold "plate" that is connected to the engine block a leak had developed after an impact on the exhaust pipes underneath.
He then started with the whole doom and gloom stories before stating the price. Eventually he said he was going to charge me only for the labor to take it out and put it back in and not for the welding. And this was going to be about 6 hours of labor with a total GBP 76.
This is where i need your guys advise, besides the above options this is my observation or solution to my problem.
Since no manifold is "cracked" and seems to be a problem of a leak where the manifold "pipe" and manifold "plate" connect. Is it not possible to get something that would seal this area. From what i remember seeing my old man fixing his car it is possible to get these things that you mix up and "plaster" around a leaking connection in the exhaust system.
*Please use a bit of imagination when i describe this cause I'm not too clued up mechanically so i'm not sure if i called some of stuff correctly.
