Corrosion on spark plugs in JDM engine???

[xXSupramanXx]

would corrosion on the spark plug threads indicate a BHG?? my guess is yes but i would like to hear from others and find out all possibilities.:1zhelp: thanks in advance everyone:icon_bigg:icon_bigg

Corrosion WHERE? On top, on the bottom? My guess is that the engine just sat outside for awhile and water pooled on top of the plug.

the corrosion was on the spark plug threads

water seeps...

Also, the two different metals cause issues as well. You have no way of knowing how long the engine sat, hence the reason most people on these forums will tell you a JDM engine is a nice ripe engine for a rebuild!

yeah that makes sense. thanks for your input

I took the head off of my JDM 7mgte today.... take a wild guess! Yup... BHG lol. no corosion on the plugs though, looks like it was taken off the road soon after the bhg starting

I still don't get the whole JDM 7M thing.....

It's at best a 15 year old motor guys it's NOT a low mile motor.

You just all seem so surprised when you buy one of these things fit and it takes a dump a short time later... :nono:

oh the 1J is not 15+ years old as well, just asking.

 

[Poodles]

even if it's not, it HAS been sitting for an extended period of time either in the clip, or bare out in the elements...

That's why most JDM engines lokk like shit with corrosion on all the aluminum parts and rust on the rest...

Some are but they kept making them long after the 7M was dead and buried so there's more chance of getting one with lower miles
