View Full Version : Possibly Stupid Question

So I posted awhile back on winterization and got a lot of help and think I got the job mostly taken care of.

Only question I have is the two block plugs on the lower portion of the block on each side are kinda odd and I was wondering if they were possible quick drain plugs or if i just didnt try to get em all the way out right?

They drained a ton of water as soon as I opened them. The previous owner ran year long so I figured this mighta been an easier way for him to drain the block in event of cold weather?

heres what it looks like. Do I need to remove these all the way or did they drain all out?

I would remove them all of the way. A possibility some crud from the motor could stop them up not allowing all water to drain completely. Put pipe dope on the threads before reinstalling :twocents:

Agreed. They are petcocks designed to drain the water. However, they can become clogged or restricted. Simple to remove and reinstall for a little self-assurance.

I completely removed mine and put a 3/8 plug in its place. I do not fool with the petcocks. I believe once you do this you will need a 1/2 or 9/16 socket or wrench to take the plugs in and out and you will never have to worry. The set of plugs will be less than 5 bucks. I have seen stopped up petcocks and have even seen them break off.

I agree with removing the petcocks and replacing with regular brass plugs. The size for the block is 1/4" NPT.

Are you sure on the size Eastie? I am thinking mine were 3/8 for the 351w. Just bought a set and I am pretty sure that was the size. I have been wrong before. Either way put brass plugs in.

I have never removed my peacock valves but after reading that everyone else does I am thinking I should. It should be easy enough to do and replace with brass plugs like the in manifolds.

I always remove the complete plug, and use a small pipe cleaner to reach inside the block to help remove any rust particles in that area. Newer motors likely don't have as much debris in there, but mine's a '97 and it always has some.

Also, if you look at the first photo you get an idea of the angle the motor sits at. Even you remove the petcocks you can see that there will still be water in the back half of the motor. One year it got so cold down here that it pushed a freeze plug out under the starter. I think it was two nights that got to 9 degrees.

From that winter on I've always put anti freeze in the boat and a drop light under the oil pan when it drops below 20. Just to safe guard against the worst case possible.

I can't believe this got away without any further comment...I love it!! :D Has the winter weather frozen us into a more sophisticated crowd???

Absolutely not, just wait a few hours, Hoosier Bob, Maristar Steve, and Tx30 Stu will chime in and blow your suspicion all to he77 in a hand basket.

Yes. Took mine to NAPA and had them check to be sure. Same on Indmar and PCM. Risers are 3/4" and block is 1/4".

Size is sort of a generalization. We're arguing about girth. 8p

If you have ever disposal-ed an impeller those bits will end up in the trans cooler and at the block drains so Skippers right.
