Re: The rebuild of the Pantera coloured 509
Are you sure there wasn't water sitting in the intake/ or heads and then when you took them off and the water just leaked down into the cylinder once you popped the head off. It happens all the time.
As far as the milky oil I see some in the picks, but I don't think it's from condensation there is way too much rust everywhere. I think you had an intake leak, and water was getting in there and mixing with the oil. Maybe! The only other I don't understand is why is that same area on every piston is clean like that. It was almost as if the water was getting in the intake side somehow and steam cleaning that part of the piston. I really don't know. Sorry! And when you say hot, holy cow that was hot!!!!! |

...I don't really know any other way that the water would have gotten there besides either reversion , Intake gaskets leaking , Headgaskets leaking , or letting go. Unless the heads have issues due to the heat. Which if I had to gamble I would say that the water was probably comming in from the headgaskets , or poss. the intake gaskets. Although I would lean towards the headgaskets because the leakdown & that it had been there before your last run. Just my 2 cents.

This might be the cause of both the milky oil in the top and the water in the cyl's. |
Re: The rebuild of the Pantera coloured 509
After seeing this last picture I really think you had a intake gasket leaking no doubt in my mind.

Something like this then... It's identical on both sides.

That intake side of the head is looking pretty ruff:eek:
That didn't happen over night either. ( running hot incident) |

Re: The rebuild of the Pantera coloured 509
The plan for the rebuild and upgrade:
New gaskets :rolleyes: New valves New bearings New valve springs (Isky tool room?!) New exhaust Honing the cylinders and a valve seat job. Check/measure the cam and perhaps replace it with a roller. Intercooler (Superchiller or BDS) and some more boost. Fix the low fuel pressure problem. It might be the pump cam lobe that's torn so if the cam still will be used then an electronic pump will take care of that part (Holley or Aeromotive?!). |
Re: The rebuild of the Pantera coloured 509
Definately get an oil themostat - either a remote or cooler mounted.
I have had very good success with the Aeromotive Pumps. Look like the parts are all reusable in the engine, that's a good thing. |

The Jesel system (I assume it is the Comp Series?!) marked and deassembled.
The rust on the steel stands is not too bad really, it's pretty easy to "clean" off, so they will look fine before reassembly. |

Yes, but the head gaskets looked fine, altough I only ran it one short turn after the incident with the broken water pump belt when the engine ran dry and got a bit too hot.
