An engine ticking sound developed from my 280ZX engine last year, which was gradually getting worse and the engine did not sound at all like a straight six should. Most advice was that the ticking noise was an exhaust leak (correct it turns out). All methods for detecting the source indicated near the thermostat housing (which ended up to be quite accurate too).
I decided this weekend to strip the manifold down. Quite a fiddly job, but following the good old Haynes manual I got there. I wanted to share some photos, and what I found:
Removing the Inlet manifold was the tedious part. But once out of the way, removing the exhaust header was relatively straightforward.
On removing the exhaust manifold it seems clear where the problem is
Options I think are : get the manifold welded and skimmed, or get a new one.
I am a bit concerned about the surface pitting around the exhaust port.
Any comments or advice welcome
