If there is a fault in HG or otherwise which is causing loss to combustion chamber?
Kinda puzzled since I been having to top my reservior pretty often and have no leaks at all. If its going into the combustion chamber I would expect the reserveior to full up since boost/combusion pressure should also pass into coolant channels through this faulty same fauly area in HG that its escaping into the chamber. Coolant reserveior rises slightly when driving, but when it cools,it falls below where it was before warming. There is no smell of coolant in the exhaust, no mixing with oil, no overflow/overheaing ,no visible leaks.

Please give me some ideas,

I had a slow leak from a heater hose at the back of the block.It took forever to isolate it.It would just evaporate off.I finally saw a little coolant around the edge of the hose.

 

I just recently had a problem similar to that. Theres a simple test that automotive shops can do. It ended up happening while I was getting my inspection sticker. Go and have your radiator checked for hydro carbons. That will tell you if its from a blown head gasket. Shouldn't be too expensive, hell, they did mine for free.
