I recently purchased a new GM Goodwrench engine. The engine was
missing a coolant drain plug and an oil sealing plug. The dealership
where it was purchased from as well as GM claimed that the customer
should know to install these plugs. Shouldn't a new engine be tested
for leaks before leaving the facory and then sealed? Were these test
ports that were mistakenly left unsealed after testing at the factory?
Has anyone else expereinced the same thing in purchasing a GM engine?
The engine was started up and run without the oil port sealed. No
information in the GM manual talks about installing these plugs when
installing the engine. I have never purchased an engine in this
Any thoughts or help here would be appreciated.
I work in a GM Dealership Parts Dept & this is new to me!
All the engines I've seen have all been sealed before leaving too.
I can see "maybe" a frost plug left open for an engine block heater, but
that's about it.
With any engine, no matter the source, and competent person makes sure
all plugs are installed before installation or start up.
While I would expect a crate motor to atleast have the plugs you mention
included, I would not make a big deal about them not being included. I might
ask the dealer where purchased if they were supposed to be or not.
The morel of this post: Don't just slap a part on or in. Inspect it
Look on the bright side--at least maybe all the trash and debris that's
always in the Mexican blocks got blown out when you fired it sans galley
plug. If the missing plug was in a location commonly occupied by
senders/sensors (ie, on the top near the dizzy on a smallblock), I would have
a plastic plug to prevent dirt entry, but a proper NPT plug probably wouldn't

GM assumes that the installer will know what they are doing.
This includes checking to see if there are any passages/ports that
need to have a plug transfered over. If this is the 3800 GENI
goodwrench, they always came without an oil passage plugged.
I lost count of how many techs in our shop installed this engine
and then had to find the oil leak.
