BIG problem 2

[G.M.]

Got started at 9:30 this morning pulling the engine in my 36 phaeton.
Got it loose and up on the lift at 11:00 but the lift cylinder was low on
jack oil and wouldn't go high enough to clear the grill so it took an
hour to get the grill out. Pulled the timing cover off the front and the
fiber gear looked real good. Drained the oil and pulled the pan the
bottom end looked like it was rebuilt last week, no sludge or metal
found. Pulled left head and found surface rust in the two center
cylinders, a hole at the top of the rear cylinder about 1/2" X 1 1/2"s.
Pulling the rear rod found one nut had cotter pin and the other nut
was a locking type. Pulled rear piston and had a split from near top to
bottom of skirt. The C & R cylinders have some small vertical scores.
From the looks of the two different nuts on the rod it looks like there
was a problem on the cylinder over 30 years ago before I got the car.
All the other rod nut had cotter pins. The left head also had a crack
from the center top stud both up and down into the large water holes. Everything on the right side lookedgood. This engine ran and sounded perfect before the problem. G.M.

Aluminum heads?

"a hole at the top of the rear cylinder about 1/2" X 1 1/2"s."

Do you mean a hole in the cylinder or the piston?

What do you think you will do to get it up and running again? (Or is it too early to say?)

Good luck with it.

Mart.

G.M. Would you post pictures for us to see what happened?

Sorry about that, yes hole in top of piston. Maybe bore the 2 cylinders
and put in two new pistons. Will check rods good to make sure they are
not bent or twisted. I have another engine I may stick in. Will decide
tomorrow. G.M.

I would have been happy to bring you some jack oil. I guess way was quicker though.

It don't look like I can put oil in the jack when extended. The engine
is hanging. First job this morning is lower the engine on wood blocks.
Pan is off then fill the jack and put the engine on an engine stand.
It's hard to work on swing around about a foot off the floor. The oil is
all in the cylinder now and there is very little jack movement at the
bottom of the stroke. Worked good when we started.Hard to work on
swinging around but was curious to see what the problem was. G.M.

This morning BAD turned to WORSE. Didn't have much time but pulled
some of the parts off the 36 engine. The pictures tell some of the story.
I had to leave at 11:30 so we pulled the plugs out of the used engine
and squirted almost a full can of Rust Buster in the cylinders, turned
the engine about a turn and used almost the rest of the RB. Will let
soak over night. Tomorrow will put mechanical oil pressure gauge on
and spin with 12 volts to see what OP will be a 45 MPH. Checked oil
and it must have been drained when the engine was pulled so put in
a gallon. Will also do a compression check. This info will help me
decide if I want to use this engine. I think I have a few others so I will
look and see what's hiding in the shop. G.M.

At least lunch looks good . . .

[Ken Crans]

Think you got enough engines?lol! Stock pile!

[Lawrie]

That looks like detontion damage on the piston.
Lawrie

[JSeery]

That is ugly!

[flatjack9]

I agree with Lawrie.

[Capt Kirk]

Hard to believe that all that happened on a short little jaunt. Did you run this engine without any previous knowledge about it's history and without opening it up a bit? Nice stock of engines waiting in the wings!

[19Fordy]

Winner, winner. Chicken dinner.
Use another of your good engines.
After all, what are you saving them for?

Without a doubt..............!

[scicala]

I agree X 3 with Lawrie. You said you heard pinging, and that's what the piston with the hole in it looks like.
