New Here With A Project

Howdy,

I recently acquired a ‘67 CJ5 project. It’s badged as a V6, so I assumed it was a Dauntless. However, it has “TURBO” stenciled below the badge and does have a turbocharger on it. A knowledgeable buddy told me it is a 230/231(?) and not a 225.

The inspection sticker on it is 2016 so I’m guessing that’s the last time it ran. The turbo does not turn so I’m not inclined to replace it. Instead I would like to remove it and bypass it if possible.

This assumes the motor still turns and is not likewise corroded. If that turns out to be the case then I’ll be looking for a new/rebuilt V6 to replace it with.

Any thoughts, experiences, ideas, suggestions are greatly appreciated.

Check out @Lockman his jeep has a buick turbo v6. Thing with turbos are they take an engine and multiply the good and the bad. I'ld get the engine running if able then figure out how hodge podge the turbo install is.
Does the jeep have an automatic transmission?
Where is the distributor and starter located on the motor?

 

like to see engine picture

 

There’s a decal on the air filter tube that looks like it used to say “Turbo 3.8 liter”

Maybe taken out of a late ‘70’s or early ‘80’s Buick?

 

Cool, yep probably out of a Regal or similar. The engine may be a dog without the turbo though depending on the compression and cam.
It's worth giving it a going over and seeing if it'll fire up as is. Carbureted model, 4bbl but looks to be an Edelbrock/Carter ( stock would have been a Quadrajet) a reman Turbo probably run you 3-400. It'll scoot if you get it running!

 

The buick 231 is the grandchild of the 225. Read the history here:

Yeah that's the earlier version of lockman's set-up. Fuel injection would be a good investment but get that running dog or no dog.

 

Valve covers show 231. I agree to get that thing running. What a project. Have fun.

 

Those draw through carburetor set-ups don't allow for an intercooler and have significant lag. Then there is no feed-back loop for fine adjustments on the road. It will need a lot of work to update the system but it will be a heck of a lot of fun to have an injector plate on top of the manifold with a intercooler. The internals of a factory Turbo motor typically have a forged crank and better rods and different pistons so putting a refurbished motor in there would throw those parts away. That's a cool project and a big opportunity so I feel like you should consider taking your time and really enjoying the rebuild if you are able to. Then you can get a few nice parts here and there then go put a 392 to shame.

 

Not sure what transmissions are which, but it is 3-speed manual and a single shift lever for 2H, 4H, N, and 4L. Where I have seen two shift levers for the transfer case in original equipment pictures this has that opening covered.
There is a lever on the bottom of the transfer case that has nothing attached to it.

 

The lever attached to the transfer case that has nothing attached to it is the parking brake lever.

 

This is where we tell you it's too far gone and you should give it to me for disposal.


Looks like it has a transmission to transfercase adapter. Also appears to have the v6 transfercase and linkage. Your used to the malnourished 4cyl case with twin sticks. On a v6 case the Texas pattern is engulfed by the round of the case where a small hole case looks like devil's tower with the Texas pattern growing out of the case.

 

A nice self rustproofing transfercase. Looks like the speedo cable is not attached. Those battery terminals under the lid, oof not much clearance.
Cool project! Fix what's broke. Safety first, run drive steer stop. Go from there.

 

Pulled the drain plug on the oil pan and the picture shows how much water came out.

I put the plug back when the water stopped and the sludge started. I think I’ll give it a day or three to settle into the pan and see what comes out next. Probably remove the pan after that and see how bad it really is.

Not exactly what I hoped to see, but knowing where the Jeep sat for a considerable amount of time I can’t say it was a surprise. The volume of water was a surprise.

 

I would gladly trade you a Dauntless V6 out of a sunken boat for your Turbo V6, it is probably useless anyway. My engine is all original with all the marine accessories intact, including total barnacle encrusted exterior and slimey rust interior. I think I know your answer......... V6 forever!

 

I'd be curious to learn the casting number on the block (behind the intake on the top of the block). I'd have to go back through my book but I remember reading about a turbo 4.1 liter Buick V6. This probably isn't that and I couldn't recognize one. Ya never know what some old boy might have tried to toss under the hood of one these critters.

 

May take a few days, my engine is completely assembled and lying upside down in a trailer. Pretty sure it is a 225.

 

I can’t see much detail in Project 67’s engine photo, but the engine is likely out of a late ‘70s Turbo Regal or Monte Carlo. The carbureted turbo engines MUST use the original Rochester Qjet 4bb that is very unique internally from other Quadrajets.
These pre-injection engines leave a lot to be desired, but they did work. The computer controlled turbo Buicks work a lot better.

And the casting number is …..

Apologies for the wait … work/life/I’m sure y’all are familiar.

In addition to figuring out that I could actually see the casting number, my son and I managed to get the alternator and it’s bracket off and remove the muffler and the attached exhaust pipe off.

I think next the oil pan comes off and maybe get an idea of how bad the guts are.
