CLOSING COMMENT - engine all back together - survived a Christmas trip to Tasmania and back (QLD) via Sussex Inlet - about 6500km all up.  No related problems, no leaks.   Did experience a problem with performance (especially uphill) in the later stages of the trip which I am 90% certain was injecto...

Oh yes forgot that - the coolant around the oil cooler was due to my earlier goof with the 'double' gasket on the water-pump exit.  It had obviously effected the integrity of the surfaces, cleaned it up and used a bit of gasket silicone over the 'o' ring and all is good.

...and we have success, started first turn, ran it for about 30 seconds without the rocker covers on for a final check on the rocker area for coolant, alternator belt was a bit squeeky.  Did another short run up after tightening belt. All good - certainly sounds much better, less rattly on initial r...

Thanks Maxstu - that helped a lot, now got a better feel for that area.  The image cleared up a lot.

OK so the initial test went well, and I'm feeling cautiously optimistic.  Turned the engine over with coolant and oil present (no belts, spark plugs or injectors), 12 times for each cylinder to get pressure readings. No visible coolant at the rocker area and the compression values have significantly...

I had a complete set of new gaskets for the original job - the top 'o' rings (the green ones) and the metal 'o' gaskets (fire combustion rings?) that fit between the cylinder tops and the heads were basically unused (just installed once and then re-used - no combustion, just one head install, quick ...

Have done the suspect side (3 and 4) - bit fiddly but managed to get the cylinders out, cleaned up and new 'o' rings fitted.  The gudgeon pin extraction tool worked a treat (see below) Had one solitary stud (see below) that I wasn't too happy with (the 'ghost' voices from forums kept nagging me to c...

Maxstu - thank you so much for your very detailed reply.  I now have a clearer picture on where I am going.  I have everything disconnected and removed (Exhaust system, engine bay guards, etc) but I am loath to drop the engine as I am not sure of the method (basic facts like where to split it) and I...

Further to the above (and gleaning as much as I could find from this excellent forum) I am going to remove the cylinder sleeves to clean and replace the lower black 'o' rings.  There's a high percentage that the leak is on the 3 - 4 cylinder side so I am going to work on that side.  My suspicions ar...

Thanks for the reply Maxstu - I'm assuming you mean the black 'o' ring at the base of the cylinders.  The answer is 'no' as I'm a bit hesitant in the method used to remove the cylinders.  My gut tells me that this the possible cause but I want as much input as possible before taking the next step. T...

I'm hoping someone can shed light on my problem with my 1990 2.1 Water cooled. I originally stripped the heads and lapped them - cylinders stuck in head assemblies but managed to prise away but they did lift out partly. Partly assembled and turned over to test cylinder pressures - coolant was presen...
