Hello,
As the engine comes apart, one of our main reasons for the this is to locate where the oil leaking into the exhaust is coming from. Our first thought was that when #1 cylinder hydro locked from the Fuel distributor problem loading up the cylinder with fuel, the rings cracked or came off. Or worse! we have not opened it up to that point to know, but the oil in the exhaust is not on the side of the motor that #1 cylinder is on. It is coming from the 4,5,6 side of the motor. we will have to get deeper into this motor before we know for sure. Any idea's? compression and leak down test were both done and leek down was 4-8% range, compression was only 95 - 115 range lowest to highest. when we checked the valves, they were all adjusted properly and we did not notice anything unusual.
The picture shows oil on the heat exchanger exterior, but this is from a leaking oil tube (tank to cooler) and should not have filled the heat exchanger/exhaust manifold with oil. Where is it coming from?
Thanks again,
Gibran
