Engine problem, cooling water leak...

[twigren]

Dear friends,

After some weeks of with my engine issues (starting problems...), I’m now back in the garage.
Still I havent solved the actual problem, despite correct ignition, fuel, air and compression.
Followed all tour recommendations and also had a professional mechanic at home, but failed to start.
Anyway, this weekend I started to dig into the details. Decided to recheck all components to be able to exclude potential issues.

As I dismounted the intake and exhaust manifold, a big problem occured.
The right bolt (at the exhaus manifold) was suddenly leaking cooler water, from the hole!
With some luck I managed the flow to not poor down in the valves....

However, I cannot be 100% sure the water isnt leaking in.
My question is - have anyone of you seen this before?

I guess I nedd to lift the engine, unscrew and go through ALL details this authum.

You have probably solved this by now, but with luck, it was just a rust out between the threaded hole and the water chamber. As you know, some of the head bolt holes go right through to the water jacket, but to my recollection this hole shouldn't. This should be a stud not a bolt, right? If so you could just use a sealant on the threads of the stud.
