1500 - water pump kaput

racingenglishcars said:
How long does it take to evaporate a half liter of antifreeze in a relatively cool muffler?

Sounds like a rhetorical question.

My answer is three.

(At least that's how long it took Mr. Owl to get to the center of a Tootsie roll tootsie pop.)
 
OK, all is well.

Despite Kellysguy warning, I freaked out after the white smoke didn't go away after 10 minutes - in fact it got worse when I blipped the throttle. I didn't run it any longer because I was worried about water lock.

Anyway I got up this morning convinced the block was cracked and decided to run it for 30 minutes as there was nothing to lose. After a brief puff, the exhaust settled down to colorless.

Phew!

OK, what's next. Apparently I should wait 'til the engine is cold and re-torque the head nuts (what is the vote on this? - seems like I'll be pushing my luck.) Also, best to change the oil and filter after doing the head, right?

Cheers!
 
Water lock generally will not happen on a running engine. It happens when more than the chamber volume (~26cl) enters the cylinder during the inlet stroke. Very unlikely to come from the cooling system unless the head breaks a chunk off.

Normally retorquing isn't necessary, but it doesn't hurt. You can just consider it like re-checking that it was done right.

Changing the oil after doing the head has a lot to do with if you spilled junk in the oil when you took the head off. (Yes you did), and then you must.

Run the engine a bit and then if you feel really frisky, check the leakdown again.
 
When you retorque the head DO NOT make the mistake that I have seen too often which is to loosen the nut and then retighten it!! Just pull it up to proper torque and stop. If it doesn't move then you are good, don't overdo it!!
(sorry if this is redundant but I have heard too many friends talk about the problems when they did it wrong)

A good suggestion, but might not be what you really want.


I myself don't like bad news. What I don't know can't hurt me.

If I think my wife is fat, I'm sure not going to weigh her twice.

Just a thought, after all; you freaked anyway knowing good and well what was going to happen. Why search for news that will upset you?

In my case, I don't like to borrow trouble.

If it leaks down, so what! It did that before the pump leaked.

This all started with a leaking water pump.....remember?

You weren't concerned about it before; wasn't concerned about it enough while down to put in fresh rings, so why be concerned about it now?!?!?!

All you'll do is say, "CRAP !!!! I wish I had put rings in it and lapped the valves while I had it down!!!"

The thing to remember about cars like yours and mine is, they aren't show or race cars, they are semi rough drivers.

The thing to do with a driver is DRIVE IT !!!!!

I'd rather drive my car than work on it. I suspect you are the same.

With the luck you have, a plug hole will probably strip.

Cheers bro, great to hear it's running.
 
Excellent news, run it like you stole it.
 
I agree - congrats by the way - put a few hundred miles on it (like 500) then retorque now, just enjoy!
 
Thanks for all the comments.
As suggested, I run it for 500 miles and then re-torque (without loosening).
Cheers!
 
Just to complete this story:

I couldn't stood any longer (as the Cajun chef says) and went ahead and re-torqued the cylinder head nuts. Needless to say, this was a "pucker moment" as the Doc says, because, once you have heard a stud rip out of the block, you will never forget it. It went without incident, although some required more tightening than others.

The engine fired right up but it was agonizing looking at the white smoke coming out the tailpipe - we are getting cold weather now, here in NC. Eventually the smoke cleared and I went for a test (as Jack says, drive it like you stole it) and it ran fantastic.

It lives, I tell you, it lives!!

Excellent news! Many happy miles. :cheers:
 
Always nice when a plan comes together. Just in time for Christmas too, great.
