Omc 3.8l

Finally i think is good, only one oil back is bigger than my head gasket to the tips, but no impact because the oil back go on camshaft 🤷. The others holes are at same positions and on other site, the description for this parts number explain it's for Buick/jeep 225 🤷
Intake gasket is same of my cylinders head

Sent this as an example & you can see these look different than what you posted….
The confusion is because there were many different GM V6 engines built, 90* Buick, 90* Chevrolet and 60* Chevrolet
 
Yes I used brake cleaner compressed air and the thread chaser. Had to do it several times to make sure the bolts thread in correctly
 
You think my gasket kit it's not good on amazon?
But on picture my original head gasket is same 🤔

Yes for the bols i used the same job 👌
 
Ok the Fel-Pro part # you have is correct for the Buick/Jeep 225 V6 but the picture in the Amazon advertisement is wrong, that picture is a Chevy 4.3 V6 gasket set I know this because I used a Fel Pro on mine when I replaced the cylinder heads. As long as the gasket set you have looks like the picture I posted I think it’s correct. Remember that from the early 60s all the way up to the mid to late 70’s the 5 divisions of General Motirs all produced their own unique engines with no shared parts. So you have to be really sure of what you’re buying. Even in the 80s—2000s there were 2 divisions making V6s, Buick and Chevrolet and no shared parts. The high point was the 1987 Buick Regal Grand National; this was a Turbo 3.8 V6 that was as fast as a Corvette! The US government used a unique version (GNX) as a special pursuit vehicle…
 
Ohhh thanks Louc, i buy this kit for the first Time.
Today i wash the cylinders head, tomorrow if it's possible i disassembled valves 🤞
I don't know if i rebuild head cylinder after to take compression or disassembled the block for inspection because i don't know what he saw previously 😅
 
In my wife’s family they had 2 cars with those engines….
1978 Pontiac Le Mans (named after famous 24 hour race in France)
1982 Buick Regal
Both nice General Motors midsize cars would be very big by European standards.
GM still makes an all aluminum direct injected version of the 4.3 V6, Volvo Penta uses it in boats…nice but very complex….
 
Ohhh oui 😅 quand je vois une Cadillac pour la première fois, elle est beaucoup plus grande que ma voiture 😅. J'étais content quand j'ai acheté ma voiture parce que la voiture a un grand coffre mais beaucoup plus petit que la Cadillac 😅



Hier j'ai contrôlé et refait les soupapes. J'ai été surpris de ne pas trouver de joint en haut des soupapes.

Les soupapes sont ok, et avec la "crème/sable" les soupapes et les sièges de soupapes sont propres 👌



Je trouve une pompe à eau Gates 43110, c'est la même que la 4.3l sur de nombreux site
 
Ok with a little help from Google translate I figured out what you were saying lol...
Glad that the cylinder heads are good, and you can go ahead with the re-assembly. I am surprised that the valves don't have seals on them, the Chevrolet ones certainly do. With my engine because it overheated and the head gaskets leaked water into the cylinders, I took the cylinder heads to a machine shop and they checked them for cracks (magnafluxing) and found cracks in the valve seat area on both heads. So I bought remanufactured cylinder heads and the Fel Pro gaskets, and new cylinder head bolts, and put it all back together.

taking it all apart...
 
Thanks would like to see yours when it’s done! This job I did in the spring of 2017. Still running great. I do a compression test and oil analysis at the end of each season. Compression is 160-170 psi.
 
No problem for me 😁🤞 i would be a children for the first start of the engine 😅
I want to do a good job like yours! (I want going to paint the engine too 😁)

But i don't find rod bearing and crankshaft bearing...
I don't know the history of the engine, when i drain the oil, i find water with oil andt the oil was thick. I think this engine was stay outdoor long time but no problem, all parts are ok.
But now the engine is desassembled (for rod bearing and crankshaft bearing control) i want rebuild with new parts 😅
I find parts numbers rod bearing, search if the good parts but no many result on google

Maybe you can help me again 😅🤷

For rod bearing i find many parts but it's for gm225 70's 🤔 i think why not possible 😅 i search to be sure again 😅

Rod bearing: Kolbenschmidt 87490600 (?) Trw 1-cb1214al (?) Sealed power 62375cp (?)

But i find pistons rings parts (i'm pretty sure):
Hastings 2m656, or 2c656 or s656 (it's the same dimension)

For crankshaft bearing i don't find...
Little problem because on other site i find 3 parts number for my crankshaft bearing and when i desassembled i find the same bearing. If the block was an jeep or Buick and rebuild whith OMC head cylinder hufr

Have you got ideas to find manufacturer and parts number for my crankshaft bearing and rod bearing?
 
If you want to see exemple, i've a picture of half crankshaft bearing and half rod bearing:

It's not perfect (old engine of course 🤷) and oxidation can be seen. Crankshaft and rods are ok 👌
 
The oxidation on the bearing insert is likely from water in the oil. I have read that water in the oil causes the oxidation/corrosion. I will have to do some research into the parts. It’s a bit challenging because those engines are not super common like the small block Chevrolet.
I also had water in the oil because 2 seasons after I had an overheat the head gaskets started leaking with salt water in a few cylinders and in the oil. I figured out what was happening & got the water out doing several oil changes…and also draining water out of the block. So I was able to save the original bearings. The 1988 block, crank, cam, lifters and all bearings are original.
I’ll do some research & see what I can find. Most likely it will come from Jeep sources since they used that engine a long time.
BTW we have 3 Jeeps in our family:
1998 Grand Cherokee 4.0 liter six cylinder
2007 Grand Cherokee 5.7 V8
2017 Jeep Wrangler 3.6 V6

Best Jeep engine ever? In my opinion it’s the 4.0 in-line 6 cylinder. All cast iron, 7 main bearings, routinely lasts to 300,000 miles. Not powerful like the V8 but lasts and lasts!
 
Ohhh thanks Louc 🤞 if you have any ideas i take it 😅
Jeep and ford in Europe have "little engine" 3l maximum i think but i like big block, i don't need power, i prefer reliable 😅
 
A simple Chevrolet small block V8 5.7 liter gives you reliability power (270 hp/300 ft lbs of torque) and the added benefit of low cost ans easy to find anywhere parts. More boats have been powered with this engine than any other at least here in the USA…
If I have to replace my 4.3 V6 one day I can move up to the V8 easily. The 4.3 is the 5.7 with 2 less cylinders. All the dimensions except length are the same. It’s about 3.5 inches longer and about 100 lbs heavier. Cost is the same with 50 more Hp and 100 more ft lbs of torque. Probably will add 10 mph to the top speed as well. However the old V6 is still running fine and used less fuel so I’m keeping it until I have to change it….
 
Rock auto is fine, many people here use it, the thing to be aware of is what brand of parts you are buying. So for example if you’re buying engine gaskets then Fel Pro, Victor Reinz or Mahle are good brands. I will take a look at the English site & see what brands of engine parts they sell & get back to you….I know an peu de Francais but not engine part names, dommage…
 
Can you see the engine type?
I take a Buick skylark 1965 225 cid V6.
If i understand, it's the same engine, no?

yes I choose these manufacturers ☺️

If you think it's probably the same internal parts, i buy all i need now 😅
 
Yes the Buick Skylark was the Buick vehicle that used that engine the most. If you were to look under Jeep you should find the same thing for the Jeep CJ series and another model called the Jeepster which was a more car style Jeep.
 
Ok checked on Rock Auto for Jeep, they used the Buick 225 (3.7) from 1967-1971. After that they made the front of the CJ series longer and switched to AMC in-line 6 cylinder. I think GM sold the Buick tooling to Kaiser Jeep in 1965 or so. Funny thing was GM wound up buying it back from AMC Jeep (Kaiser sold Jeep to AMC in 1970) in the mid 1970s when they needed more economical Engels due to the oil embargo of 1973/74.
