I am having some leakage problems with a 2.0 4-cyl and I am trying to narrow down where the leak is coming from.
I thought it was an exhaust leak, but have changed heat exchangers, had the new exchanger off several times and Can not seem to see any evidence of the exhaust leak at the copper exhaust gaskets. None of the exhaust studs are loose or pulled. I even went to the extent of changing cylinder heads, but the leak remains. When I changed cylinder heads, I did not know of any information regarding the elimination of the cylinder head gaskets, so I believe that I have them installed. How likely is it that the cylinder head gaskets can be the source of a leak? My exhaust leak is intermittent when the engine is up to temperature. (It is quiet while it is warming up idling, but after it is warmed up, sometimes at idle you can notice what sounds like a slight exhaust leak. Not real loud, but noticable) I was thinking that it may be a cracked cylinder (near the mating surface of the head), but the more I have read about the elimination of the cylinder head gaskets, the more I think that the leak could be those aluminum gaskets. Does anyone have any information with regards to a bulletin released concerning the elimination of these cylinder head gaskets, and could I get a copy? I would greatly appreciate some advice on this matter. Thanks. |

Grab my video and you'll see an awesome example of what a blown head gasket looks like on a TIV.
The gaskets are made from 3 pieces of .007 aluminum alloy. As soon as the cylinder heads are overheated once and the heads are not re-torqued the gaskets get a bit of combustion under them and its just a metter of time before those layers of alloy start to come apart. It seems that me and the Cap'n have finally found an argumment! LOL |
