Classic car technician Jon has been investigating the exhaust blow (blowing noise) on our 1972 Jaguar E-Type V12 Series 3. From listening to it, Jon believed that the issue seemed to be coming from the offside bank of the exhaust manifold.

To confirm his suspicions, Jon had to strip and investigate this area of the car.

After a bit of work, Jon was able to gain access to properly investigate. He found that the front manifold of this classic car was cracked and was causing the blowing noise coming from the exhaust.

The front manifold was removed and was found to be in need of replacement. While Jon was waiting for the new part to arrive, and while he had access to it, he removed the rear manifold too in order to check it was in better condition than the front.

Jon went on to clean all the parts and mating surfaces ready for the new parts to be fitted. Once the new parts have arrived and have been put into the car, Jon is hopeful that the exhaust blow would have been resolved.

Work will continue on this beautiful Jaguar E-Type to make sure it is soon ready to leave the Bridge Classic Cars workshop and be returned to its owner. We know that once it’s back out on the road, it will be extremely enjoyable to drive and experience.
