Just bought a 1983 TA, has a heck of a exhaust leak somewere in the manifold area near the O2 sensor, any ideas how I can fing this noisy leak.
Maybe its a cracked manifold.

Check for manifold bolts that have fallen/broken off in the head and y pipe flanges/studs that have rotted out allowing the pipe to come loose. Is the 02 sensor still in place? I've seen them fall out on occasion.

Thanks for the advice, already checked it seems to me on the top
inner section. Do they make any sealer gasket for this or do I have to
replace the manifold.

You can try using a piece of small diameter hose, put one end in your ear and run the other end around the manifold. Check around each exhaust port and around y pipe flanges, and around the area you suspect is cracked. You can clearly hear exhaust rushing out of any leak through the hose and isolate the location.

Good Idea,
Thanks
