Engine Been a while since I’ve posted. Oil in coolant.

[Jimmy5]

Don't think its the Head Gasket at all! My 1996 Mustang 4.6 v-8 had similar problem. It's a bad O-Ring at the Oil Filter/water coolant adapter. This is behind the Oil Filter base, an adapter plate. Got the repair kit at Advance Auto Parts.

Also water system is under pressure. If bad Head Gasket, water would go into oil. If bad Head Gasket: water leaking into pistons. Turns into steam, out the tail pipe. Take out the Spark Plugs and crank engine (water would pump out a Hole on the particular piston). Do a Compression Check on all cylinders.

On a Intake Manifold Gasket leak check by spraying Carburetor or Brake Kleen around edges of manifold.

5.0 push rod engine does not have a oil cooler adapter.

I just decided to pull the whole thing apart. Turns out I was running on 7 cylinders. No clue how I didn’t notice that between sound and vibration...

Just pulled the whole top end apart. #3 hasn’t been running. Spark plug boot was melted by header.

Any update on the coolant in the oil issue?

Nothing visibly wrong. I played it safe and changed head and intake gaskets.

Good call! Hopefully that solves the problem!

We just got it running, and it melted the spark plug boot on number 4. What do I do to insulate the boots?

 

[General karthief]

DEI boot insulators

DEI boot insulators

I got a set of them. How in the world do you get them over a 90 degree boot? It’s harder than trying to staple an egg to a brick wall.

90 degree boot on the spark plug end?

90 degree boot on the spark plug end?

Yessir. Is that uncommon?

Carburated 79-85 5.0 wires have 90 degree boots

EFI are more like 45 degree or straight usually

Unless you can get your exising sleeves to slide down, for 90 degree wires you can get either these

or these

Thank you. I’m gonna see if I can get these to work before waiting any longer to get new stuff delivered. I just want to drive my damn car already!

Which of the two do you prefer/recommend?

Best wires for a fox body v8 are LiveWires, however I have been using the FMS wires on these cars for 25 years . Some people complained about them arcing but I have never had that issue, I've never had an issue with the FMS ones. They are on my 500hp car and my stock 225 hp car

'I really want to drive my car' can lead to short cuts.
I really want to drive mine too but I also don't want to tow it home so I practice patience. I spent 2 years chasing my tail then I put a stock engine in it and drove the snot outta it for several years gathering parts and now I'm working on the engine again, but it will be dependable when it hits the road.
Patience young jedi, patience.

Had that on a 4.6 modular block. But that’s not an option for a cheap fix on a Windsor block.

To everyone that helped me here, thank you very much! The car starts instantly, runs great, and pulls like a beast! I still have a bit of carb tuning and brake stuff to do, but overall, I am very happy!

 

[Cheapskate207]

Great! Glad it worked out
