I had an '03 D2 that eventually died due to a slipped #5 sleeve. Allowed exhaust gases into the coolant system thereby pressurizing the coolant to the point it was pushed out of the reservoir.

Leading up to that, coolant would leak into the #5 cylinder during non-running periods and cause misfires during initial startup, until the coolant was burned out of the cylinder. That occurred for several thousand miles.

During the whole process, I had the "ticking" noise from the engine, that is usually associated with a slipped sleeve. Eventually removed the engine and after pulling the #5 sleeve, found the block had a small crack behind the sleeve.

Flash forward to today. I purchased an '04 D2. It has the same issue of coolant leaking into the #4 cylinder when the engine isn't running, but there is no ticking noise.

Am I looking at just a bad head gasket with there being no ticking?

 

the ticking could have been a number of various issues but the only way to find out would be dive into it man

 

First ensure that you have coolant in your cylinder.

I don't think the '04 will slip a sleeve because the way that the sleeve is captured both top and bottom in the block unlike previous years. Coolant in an interior cylinder is most most likely a crack in the cylinder sleeve since there are no water journals in that area (this has happened to me). This can happen from two main causes: overheating or eventual crack due to head bolt over torque from a previous head job.

A leak in an exterior cylinder COULD be from a head gasket leak since the water journals are in that area. Pull the head and very carefully inspect the head gasket for signs of breach.

Keep in mind you still have to solve what caused your overheating issue to begin with.

 

Oh, I didn't realize the '04 block was a little different from the earlier models.

Thx

 

Blocks are the same.
Coolant in middle 2 bores is most likely a cylinder wall crack behind the liner, no water jacket passageways near these.
Coolant in the end bores is most likely head gaskets, water jackets on the ends, but can still be a crack.
