Re: 1 freeze plug diddled!

Jeesh, you guys are slipping.

It own't a freeze plug.

Does it really affair??

I've been a motor head for over 40 years and worked at many shops and not ane mechanic has ever chosen them "cadre or casting plugs".

Does that mean all those mechanics including me were/are wrong.. No.

Due to the fact that they have been called that by near everyone for so long (even parts stores, engine builders etc) - that'due south merely how nigh people understand/reference them.

Why yous may ask... The "initial" purpose of the hole was to facilitate casting. The "current function" of the softer metal plug is non only to fill the hole yet help protect the block from inadvertent corking due to swelling ice/freezing. Hence the name/reference to "freeze plug."

Hopefully the OP did "contrivance a bullet." But equally mentioned to a higher place, I too would be concerned equally to what I did wrong with my winterizing process.

- Either name works.

Cheers

Re: i freeze plug blown!

Now you did it, you just let the biggest surreptitious out
Freeze Out Plug = When you get out water in the block and information technology freezes ,information technology causes the plug to pop out. The ice causes the plug to pop out normally after the block is croaky.

Now you did information technology, yous just permit the biggest clandestine out
Freeze Out Plug = When yous get out water in the block and it freezes ,information technology causes the plug to popular out. The ice causes the plug to pop out usually after the block is cracked.

Yep, I've seen it get both ways. Fifty-fifty those that didn't know information technology froze permit alone a "plug" was forced out. All was well until they drove the vehicle and overheated the engine. No cracks but DOA due to both heads/decks warped to H...

Wishing the OP the all-time!

Re: 1 freeze plug blown!

well gunkhole is going to the shop today to become the block checked out, they are going to fill information technology with air to check the force per unit area and then drive it up and down the river. I put the temp safe plug in there and ran it for a while, information technology seems to be okay, i hope information technology checks out. Has anyone else had one blow out and not had any damage?

Newbie here.

I wish I were so lucky. I endemic my used 232 eclipse iii weeks. I bought a manual, followed the guides and pulled all the plugs on the 7.4L and got virtually 2 qts total of water out of cake etc and thought i was skillful. ( I didn't know what to await)

Once it warmed up i took her out and one) took on a lot of h2o thru the freeze plugs into the bilge earlier I caught it two) hammered the plugs back in at the dock and let it idle 5 mins while checking oil for water. I thought I got actually lucky. 45 mins downwards the lake I heard a bearing squalling and pulled over. I had water/oil spewing out my dipstick....all 7 gallons of information technology!

$1k and about 60 hrs of labor and I'm back in concern with a new motor.

I'm at present way too familiar with most of the systems on my boat!!!

Newbie here.

I wish I were and so lucky. I owned my used 232 eclipse 3 weeks. I bought a transmission, followed the guides and pulled all the plugs on the 7.4L and got well-nigh ii qts total of water out of cake etc and thought i was proficient. ( I didn't know what to expect)

Once information technology warmed upwards i took her out and one) took on a lot of water thru the freeze plugs into the bilge before I caught it 2) hammered the plugs dorsum in at the dock and allow it idle 5 mins while checking oil for h2o. I idea I got really lucky. 45 mins down the lake I heard a bearing squalling and pulled over. I had water/oil spewing out my dipstick....all vii gallons of it!

$1k and about threescore hrs of labor and I'm back in business with a new motor.

I'one thousand at present way as well familiar with most of the systems on my gunkhole!!!

ouch... as a new boat possessor, I wasn't satisifed with the corporeality of wate that drained out of the port, aft core plug. Shot a blast of air in there and out came the nasty, rusty, junked up water. Virtually another gallon OF IT! Glad I did that or I would be fixing some damage myself.

Re: 1 freeze plug blown!

everything is good with my engine!!!the pressure level test was proficient and it ran fine at operating temperature. Although the mechanic says my outdrive needs some work. I replaced the bellows terminal summertime also as the begetting and ujoint, shift cable, etc. He said it needs to a seal kit because its noisy, whatsoever stance on this??

Never heard of a seal kit causing the O/D to make noise. Maybe hes mad the engine wasnt cracked and wants some more coin?

Take you changed the lube in the O/D this season?
