All of my blocks have had the
4G63
RE 4068
type of numbering on their pads but I don't have a breakdown of what the particulars mean. Mine, of course, have had different lettering and last 4 #'s but all said 4G63 above it...before I stamp my OWN identification marks on them.
Sorry, that's not much help, was there a particular question that you were interested in?

you could try running the vin @ https://www.vindecoderz.com/EN/Mitsubishi/ECLIPSE also according to this the vin should be stamped on the engine block also as i read here " As stated before, the VIN number of the car is also on the short block. I think it was on the timing side of the engine. It's dirty there so you may have to clean it off." ....another poster said it was on upper trans side ....hope this helps

also found this service information on updates to torqueing that were wrong in the service manuals ...for 92 to 95 4g63 and others ..http://www.rebuiltautoengines.com/mitsubishi-galant-articles.html

Pat is correct, the VIN for the car should be on the block in a small area (not the ID pad) and on the transmission also.

Thanks for reply “...Talon”. I’m trying to figure out if my 1995 is a 6 or 7 bolt engine because the guy I bought it from has no idea. I bought the maintenance kit from extreme and just trying to verify if the parts of a 6 bolt and 7 bolt are interchangeable.

Sincerely,

Nelson

Nelson, look at the oil pan on the pulley side of the motor, from underneath the car. A 6 bolt is FLAT across the entire oil pan flange. A 7 bolt will have a "dip" in the pan at the harmonic balancer area. I would put my fingers on the lip of the oil pan and follow it along that area and see if you feel it dip down or if it is flat. That will help tell you what you have.
Maybe a picture of that area for us to see and help you out.

Here are a couple pictures of the difference:

Thanks again guys! The oil pan is straight . So it’s a 6 bolt but it’s a 95 eclipse GST. I was under the impression that these were 7 bolts? Please correct me if I’m wrong. Just bought the maintenance kit now next step is changing all the gaskets from the engine. Only the lower gaskets will change because everything supposed to be the same right? If I’m gonna start playing with this unique Diamond then I better get it right the first time.

Thanks,

Nelson

all 95's came with a 7 bolt.
if you have a 6 bolt its obviously been swapped in.

Thanks Dusty! I thought the same thing. I’m just trying to verify. So I know how to proceed in this build. Any pointers would be greatly appreciated.

Thanks,

Nelson

Another thing you can look for is the end of the water pipe, where it connects to the thermostat housing. On a 2g, when you swap in a 6 bolt, you have to use a 1g water pipe.
So if you have a 2g car and the water pipe angles downward (1g W. pipe), its a 6 bolt.

You should take a look at the Magnus 1g in a 2g guide.

Thanks. Dusty. This will be very useful.
Was talking to the guy who sold me GST and he said this is the exact car. Only that I got it without the turbo, intercooler, and exhaust manifold etc. it has a galant manifold so technically it was stripped.

Thanks,

Nelson

A 6 bolt will be bolted to the trans with 4 bolts. There will be a section on the front of the trans that’s missing on the block.

At the 2:57 mark and the 3:46 mark on that video, the water tube appears to point UP. Anyone else see any clues?

If using a 2g head/1g block, I believe you'd still use the 2g water pipe due to the t-stat housing, right?

Otherwise I couldn't see any other evidence to identify things by, almost thought I could see the trans-to-block flange that @donniekak mentioned, but no dice.

Im a dumbass. I was completely wrong. I think i stayed up way to late cause it made sense some how before i took a nap.
sorry about that

You would use the water pipe that matches the thermostat housing. Since it is possible to bolt up a 1G thermostat housing to a 2G head, one would need to look beyond this bolt-on accessory to determine what the engine really is. And so we are all clear, 1G does not automatically mean 6-bolt.

The engine in the video (note: video was originally posted to Youtube in 2015, so keep that in mind, OP) is clearly using a 2G thermostat housing, which means it is a 2G head. Also verified by the lack of a cam sensor on the passenger side, it must be under the intake cam sprocket. At 3:41-3:42 in the video, the point that @donniekak brought up can be seen - the transmission is utilizing that 5th mounting bolt to the engine block. These combined tell me it is a 2G engine all around. But again, it is a 4-year old video...

OP's best bet is to look at the oil pan as @1990TSIAWDTALON Marty suggested above or do more research on what the visual differences are between a 1G and 2G engine and 6-bolt and 7-bolt engines. If the OP were to provide pictures, we could help narrow it down from there. Until then, that's really all that can be said.

Thanks. I’ll take some pics tomorrow of the oil pan for you guys and me. So we can put this baby to rest.

Thanks,

Nelson

Good day. So I finally got under the car and found the dip on the oil pan. So it’s a 7 bolt.
Thank you all for your guidance.

Glad you got it figured out Nelson!
Always glad to help out our buddies to the south of us!
