What are symptoms of a head gasket beginning to leak if already leaking?

 

Depends on how it is possibly blown. Could be coolant slightly leaking, loosing compression, milky oil, etc... what exactly are your symptoms? I'm in the process of replacing mine right now on a 2000 disco II with 154k I wasn't loosing compression or power and my oil was clean. I had a minuscule coolant leak coming out of the left rear (#8 cylinder) side. I blame dexcool but that is me personally.

Or could be a noise that resembles an exhaust leak. White smoke from tail pipe. Etc

 

Yea that another symptom. The symptoms could be endless depending on what is making you think you have a leaking head gasket. I know if you are around Birmingham, al, cylinder head service will redo heads on our rovers for $95 per head and then they will clean the upper n lower intake for $25 if you have heads reworked by them, if not it's a bit more. The do top notch service and the turn around is usually 2-3 days. I also found out that since a lot of people down here are starting to restore them and rebuilt them, they rebuild the Thor and gems engines for between $2500 and $3000 and there are a few guys around here that have had them do theirs and love the work they do. I'm not trying to get them business or anything just making a recommendation for folks around my neck of the woods. It's hard to find a good dependable shop nowadays. They have redone the head on my work car (2006 Ford Focus zx4) and have had them do head work before on ford trucks. If anybody know a good place around bham, al to have the valve covers powder coated, let me know please

 

This is my symptom.

 

If I'm looking at that video correctly, you have removed the a/c compressor and power steering pump on the drivers side(left side looking from the interior). It looks to be a lower intake manifold gasket and not the head gasket itself judging by that stream. That will be where the coolant goes from the head into the intake. If that's the case, you can get away with just removing the intake and not having to replace the head gaskets. You will have to remove the valve covers. What year and how many miles do you have on it? Personally since you have to go that far in it, what's a little further to get the heads off and have them reworked so you know it will be all done properly. You can get a kit from lucky 8 for under $100 with all the gaskets (except throttle body heater). Somebody else might chime in by your head gaskets seat between the head and the block and the lower intake gasket it was covers the cam, lifters, pushrods, etc and seals between the intake and head and that it where you nice stream seems to be coming from. Worse case, you could have a cracked head or intake. Has anybody messed with the intake that you know of and are you getting a milky oil?

 

 

Thanks. We replaced the head gasket already and we are in the process of finishing the entire installation. Just waiting for some bolts from Paul Grant that got misplaced along the way.

 

Can't view the video posted above, however, if it is the same one as you posted before...this was definitely a head gasket leak.

Time to deal with the head gaskets.
There is a mental block where as you "accept" it and start to take the engine apart.
