Motor Maddness!!

[tokiMK3]

does anyone know which motor this is? 7m? 1j? 2j? all I know that its a twin cam. I'm planning to rebuild this motor, or is it worth rebuilding? or is there a certain thing that tells what the motor is

 

[natedogr]

that looks like a 5m or 6m. is the head slanted at the top? if so that def a 5m or 6m

 

[suprawalt]

ya thats a 7m motor do u know if it was turbo or not.it should be worth rebuilding.

 

[tokiMK3]

I dont know anything about the motor.. is it possible to tell the diff? and how do u know its a 7m?

Slanted valve covers = 5M-GE or 6M-GE
If the crank is stamped "7M" it's a 6M-GE

Or count the valves. 12 valve = 5 or 6, 24 = 7

6M-GE = 5M head on a 5M block with 7M crank.

I think. Don't quote me on that last part.

 

[natedogr]

no im pretty sure thats not a 7m. its gotta be a 6m or 5m. look at the way the top of the head slants off to the side. and also the rear timing cover is all one piece, on a 7m the rear timing cover is divided into two different pieces

 

[zachm611]

i would think it would say somewhere on the block what it is. look around for writing or something.

 

[Tanya]

It is definitely a 5M or 6M, although I am leaning more towards 5M.

NOT A 7M.

The engine designation is right near the oil filter

Cam gears look like the 6m I worked on :dunno:

I don't know if th 5m gears are different?

 

[Tanya]

6M cam gears are the same as 84-86 5M cam gears. The heads are the same folks.

 

[tokiMK3]

6m is it then..

 

[Tanya]

wtf.

you know it is a 6M because...............?


Did you look on the block??

 

[MassSupra89]

It will be stamped right into the block on the exhaust side... like Tanya said.

Look around.

 

[IJ.]

wtf.

you know it is a 6M because...............?


Did you look on the block??

LOL

this is the downside of forums:

- some can say with absolute certainty what the answer is....and be completely wrong.
- some can read the right answer and still think completely wrong...

actually, 6ms have 6m cranks.

86-88 7ms have 6m cranks

 

[BlackMKIII]

I thought I was wrong there.

 

[TurboStreetCar]

Also not a 7m because the thermostat housing is on the wrong side......

 

[Tanya]

OMG

LOOK AT THE DAMN CASTING MARK ON THE BLOCK.

no one cares about the 6M crank and whether it came in an early 7M block or not. this CLEARLY has the 12 valve 5M/6M head, which is what we are trying to determine
