I have an 84 D50, 2.0 4 speed. I bought it not running and just pulled the valve cover. The head is very obviously newer than the motor/truck. I've worked on these before and I've seen both operable valve jets, and I've seen the plugs in place of the Jets. On this one, it has neither, and the cam rocker doesn't even have the extension you see coming off to run the valve jets. Has anyone experienced this before?
Sorry if some of my terminology is off, amature mechanic here.
Welcome to the forum, SFB.
It never ceases to amaze me the new things members come up with/experience,witness, on this forum.
My guess is it might well be a 2.4 head or some similar swap. How interesting.

I'm sorry, was that supposed to be an insult?
I've never seen an 82-86 2.0 without the valve jets, am I completely wrong?
My 86 2.0L had them MCA jet valves, 1st Gen. After cracking heads several times I finally got another head without them and have been golden ever since. If you have the valves still in place without them being in use, it be best to remove them and install the kit. I hate to think that the springs on the jet valves are the only things holding the seal in the combustion chamber. It is obvious someone has done head work because they don't come from the factory that way.
I also think Roy wasn't dogging you as you may think. Roy is not that way, as long as he has a donut in the morning. You maybe need to take a look at your screen name since it does kind of seem degrading yourself. Maybe change it to CarbonferBrains or better yet...BrainsferBrains, just saying. No hard feelings...
Welcome to the forum.
a picture would be very helpful. they did make 2.0 heads with no valves, so they do exist.
Haha thanks for the info Brad. And yeah, I'll get some pictures up. The bypass plugs haven't been installed, the head is simply made without the jet valves, to my pleasant surprise.
yup you got a good head then, cherish it
Not sure how you derive an insult from that, but I assure you I do not insult people. It truly IS amazing the various things that people discover with these trucks.Originally Posted by ShitFerBrains
Anyway, quite an amiable member, I again welcome you to the forum. Lots of guys here have twisted senses of humor, so try not to be defensive: we're really a happy community across the board.

Twisted? who in this forum has a twisted sense of humor? (don't say it Roy,) or I will give you a nuggy so hard it will leave a mark.
My G63B is a non-jet valve head. It appears that the MCA-JET valves were not a mandatory introduction to Mitsubishi engines sold here in Australia. I am having a hard time finding one that isn't hydraulic though!
Yeah I'm sorry, starting to get a better feel for the community, wasn't intending to be sensative. And the more I read the more I agree with you, the variance is astonishing on these trucks. Very fun though.
I cite MIHIFISI's thread, "I'm a sick, twisted bastard..." for one. http://www.mightyram50.net/vbulletin...wisted-bastard
And I was threatened not to reveal the rest or I'll endure an impossible consequence. (Not everyone wears underwear, JFTR).

There's the pictures of the head with the valve cover off. Simply no jet valves.
I'm no expert, but I think that's a 2.6, not a 2.0. I only say that because of the timing chain instead of a belt.
Whatever it is, it sure is clean!

yup yup that is deff from the astron family. either 2.0 or 2.6 not my engine flavor thou
2nd that being an astron motor, so a non jet head is definately available for it. And from the looks of the fitting on the front of the head, it is a 79 - 82 setup, possibly a caravan head which were non jet valve heads.

aha is it a g52b or a g54b?
2.0 or 2.6. very interesting.
He is keeping us in suspense, perhaps it's both and a top secret Mitsubishi build motor that only one was ever made of. Naaaaa! lol
Haha I couldn't tell you. Like I said, amature mechanic here. It's definately a 2.0, but not the stock head. That's about as far as I've gotten for sure. I was just pleasantly surprised to not see jet valves so thought I'd pick your guys' brains.
There should be a metal tag on the left side of the firewall, and information about your truck is on it. Though the engine might have been switched out, it will reveal what engine originally came with the truck. Copy the eninge number down and post it: we can go from there.

The engine block also has a stamp marking the engine. It is on the passenger side close to the oil filter on the flat close by. The identification is between a 1/4in to 1/2in sized font so it's not real small. It may be faint though. The stamping wasn't hammered hard at factory, just a subtle placement.
Here is a 2.6 G54B and it sure looks like that is what you have. There is obvious items that show this and one is the oil filter placement and that chain for the timing. Mitsubishi didn't throw chains on hardly any motors. One was the G54B and is identical to yours. Click image below to expand.

Hey that's some good info, thanks guys. I'm in North Dakota working and the truck is back home in Idaho so when I home I'll check into it. Based on that diagram, I'd have to agree that my motor looks like a 2.6l. I do remember seeing the oil filter below the exhaust mani on the passenger side, as depicted.
I score another dozen donuts!...which I sorta have to use to pay for another thread I offered them on in exchange for information.
