1968 Chocolat oil

[franklinair]

Prepping things to pull the engine in order to paint/detail the engine & engine compartment. The drained oil came out milky brown.:sad:
Teardown/overhaul now on the agenda.

Neil,
I changed the timing chain cover so you may want to check that area first.
Could water be running behind the cover and into the pan?

 

[franklinair]

I'm going to first do a compression test, then pull the water pump & timing gear cover to see if anything's going on there.

Dad,
Is this the car I looked at for you? I can't keep up with you!

Hopefully the bearings are ok. If you get that much water in the oil, it doesn't take long before they're toast.

Rob- this is the Highland Green 289 I got from Arlie. The Black Beauty is next year's project.
Steve- I'll be looking at all potential problems. The engine has hardly been run at all since I got the car.

Neil,
Does not happen often, but an intake to head seal at the front and back of the manifold can let some water in.

Neil,
Could water have gotten down the carb when the car was at the body shop?

 

[franklinair]

Arlie- the car was always inside @ the body shop. I'll check out all possibilities of coolant getting into the oil.

Today's findings: Head gasket leak, cracked exhaust manifold. Bearings/journals looked OK but will be verified tomorrow.
Water passages in heads pretty clogged up- which also coincides with the restricted radiator flow. (New core this week, made in the USA.)

A blown head gasket is the best possible cause of the water!!!
Which exhaust manifold is cracked? I replaced the driver's side manifold because it was cracked, then broke in half when I removed it.

 

[robert campbell]

Arlie,
I have never seen a 289 exhaust manifold broken like that. Wow!

Rob

 

[franklinair]

Preliminary findings:
Crankshaft & journals all OK.
Engine had previously been bored .040
Rob has given me info on upgrading the cam.
New exhaust manifolds ordered.
We'll talk to our parts supplier about which O/H kit to order tomorrow.
Heads are out for rework.

In the meantime I've installed the new main harness (for lights, V/R, solenoid, fog lights).
Ordered new parking light units, installed new Mustang scripts, head light buckets, new Battery tray, new hood hinges).
And the beat goes on...

This will be one nice car when done!! Highland Green and done by the God Father of the GT/CS!!!!!! Wish I could afford it!

Rob has given me info on upgrading the cam.

Nooooooooo!!!!!!!:icon_pani

 

[franklinair]

Not to worry, Arlie. It will be no more than a K code 289, with the Edelbrock Performer intake & 500 CFM carb, Pertronix SS ignition.

Very very mild cam selections. Mostly they work better than stock due to the new technology and materials that allow for steeper ramps on the cam lobes to provide more duration, without any effect to the idle or vacuum in a stock engine.

One would not know that it is in there at idle. Now Val's engine, oh baby, do we have her "cammed" up!!! Funny though it is a solid roller cam and it still works fine with the power brakes. This is due to the ability of a solid roller to have enormous duration without the killing effect of "overlap" that kills the vacuum signal at idle. It has a lazy idle compared to the old "rumpateee rump" of a huge flat tappet cam. But you can tell something is not stock in there!!
