Author Topic:   Water in the Oil
posted May 04, 2003 09:22 AM
Went out for parade lap and unknown to me I was smoking out the tail pipe, I got half a lap in about 4,000 rpm's 170 degree water and still running 65 psi on the oil. Then I let off a great big white smoke ball some noise, motor shut off.
I plan on starting to pull it apart this week.

Water in oil, no oil on ground.

A couple of question, I'm thinking blown head gasket or cracked head.

If I pull the top end off and find one of my thought's correct. Will I have to go into the bottom end and look for a bend rod or anything like that. (Silver-Lite forged pistons, eagle forged rods.)

Any other insights would be helpfull.

If it shut off fast then it probably hydraulic'd a cyl and if it didn't bend or break something it would be a miracle,also check for bearing problems but in a half lap you may not have hurt them.

With you "if you didn't bend or break something it would be a miracle" statement.
I'm thinking you saying I should pull the motor right out of the car and turn it over a check the bottom end?

you cant see a bent rod. or usually a cracked cylinder wall for that matter.

Started pulling the top end off the motor.
Not looking good, water poured out of cylinder 1 and 6, 3 looked wet on the plug.
Cylinder 7 spark plug had a missing insulater, electrode half gone, and plug gouged up.

Then took off intake found a bend pushrod on #7 cylinder.

Still need to pull heads, not looking forward to what I think may be under them.

1st night out, crash and bend rear end, because of someone else's mistake.
2nd night out wreck motor, not looking good.

I did post more in the engine section.
I did get it all apart, final outcome not as bad As I was thinking.
First off I took off the heads, #2 piston chipped, #7 in about 15 pieces, connecting rod and Wrist pin still sitting up in cylinder.
We then took everything apart, metal pieces everywhere in the top end.
The good news was all the rods were straight, crank was good, all the bearings were good and tight.
It looks like 2 bad pistons, 1 bad push rod, 1 bad head. and need to get #7 cylinder sleeved.

It's a pain in the rear, but it could have been a lot worse.
After we blew the motor the next week we had a rainout, this week the sprints are in, so hobby's don't race. Trying to have it ready for next week.
