So this DEFINATELY is NOT a good thing!

damn.

:shock:

It is oil, where do you think it is coming from? I wouldn't think it would immediately for no reason start leaking through the rings that bad on the drivers side after not burning any oil or smoking at all...

What is ya'lls opinion on what happened?

:razz:

Other than a ring, possibilities include a blown intake gasket allowing oil to be pulled through the intake runner(s) from the valley, a bad PCV, bad intake valve seal(s). You said "drivers side" so I assume a V8. Based on the pulsating oil cloud would be looking at left intake gasket for a leak first. Look in the intake runners under the carb for signs of oil.

most likely a valve guide seal. did it start after suddenly or did the engine get wound a little tight and then start smoking? Valve seals are terrible for decomposing and falling apart. I would pull the valve covers and make sure the seals are intact before digging deaper.

One morning I started it up and it was smoking light a freight train, never smoked a bit beforehand... I don't hot rod this motor due to it running on only 7 cylinders due to a flat cam lobe. The lifters/rockers/pushrods have been removed from the #1 cylinder which has the flat cam lobe.

Dude, Just fix it!

Having the lifter removed is VERY BAD. Pressurized oil flow to the mains will be almost zero. You're looking at some serious internal damage.

I had a 304 that smoked like that because it broke rings due to detonation. I pulled the plug wire and the smoke stopped for a while. The oil eventually migrated down the header tube to the collector where it was heated by the other cylinders and the smoke resumed.

Time for a full rebuild. The longer you put it off, the more damage you do to the block/crank/heads, and the more it will cost to make it right.

ok aside from he oiling issue (And If the lifter is out of the hole I am surprised it hasnt shelled the mains by now.) The easiest way to figure this out is to pull the plugs on that bank and find out which hole is burning oil.. then search from there.. but dude it's broke, Dont torture it anymore just fix it.

:shock: darwin where you at?

rollen dean montoya

rebuild it dude. hopefully you didn't fry the main bearings by pulling the lifters from #1 cyl. the moment you spotted the flat lobe that is when you should have overhauled the engine

Definitely time for a rebuild, before you seize it up.

scrible88

Well I could care less if I seize it up, all this motor is going to be used for is a core when I drop in a 401. It has ran fine without the two lifters in that cylinder for well over a month even with highway driving and the mains seem fine to me. It still has good oil pressure... I've never heard of that causing a problem before because I've known several people to do it when they lose cam lobes and none of them have had problems. They were with ford and chevy small block's though. 111!!!

darwin where you at?

What in the hell is this reply for? Are you trying to get at me? If so take your worthless comments elsewhere.

You can't compare AMC to Ford/Chevy. The oiling systems are completely different. If you look at the AMC V-8 oil flow, all the oil from the pump flows up the front passages of the block, down the lifter galleys, then down to the cam, rod, and main bearings. By pulling a lifter or 2, you create a huge hole that the oil runs out of before getting anywhere. I had a rocker bridge break and a lifter pop out. My pressure immediately went to nothing. The gauge measures pressure right at the outlet of the pump, but I doubt you're getting enough oil where the engine needs it most. Sounds like you're not too concerned about this engine, so run it till it blows - or you get a ticket for polluting. The only way to find out what's causing the smoke is to tear it down. Bob tufcj

I'd imagine gas is getting into the oil thinning the oil etc... Slowly chewing the cylinder walls and rings not to mention any other seals... Dude... when the Dog is suffering you have to know when to put it down.... Take it out into the woods for one last hunting trip and put a round in it :snipersmile: Then start new man... Hopefully learn from the experience... AMC's are beyond sensitive when it comes to oiling... :sa:

allow me to retort.
i guess i should have used several :shock: emoticons. first, i'm shocked that the engine is running that decent on 7 cylinders. second, shocked that anyone would not use the vast info about the amc v8s, especially the oiling, on this board to understand the engine before causing a major internal oil leak by pulling out a lifter or two. third, amazed that the engine ain't knocking like crazy on the video with the lifter(s) out. the darwin comment was just a little ribbing, meaning the same that others have said just more colorful words.

anyway, i have a theory why the engine hasn't grenaded yet. a block in the lifter oil passages for #1 cyl. caused the cam to grind itself flat because of lack of oil. now the block in the passage is the only thing saving the mains and rods.

so you're planning on a 401 swap using the 360 as a core. let me guess your plan. go the local flaps and order a 401. when it comes in turn in your 360 for the credit. now if the parts jockey misses the big 360 on the side instead of 401 and issues you credit, i guarontee the engine company won't when they get it. next the engine company will not issue credit to the flaps because the engine people aren't gonna lose money. so the flaps will do one of two things. either try to get a hold of you to get the core charge back (if the do, great) or expense it out. now, if the flaps is locally owned, you're just hurting your local economy and helping the big auto-parts boys put them out of business because locally owned flaps can't mess with their prices much. now if its a nationwide flaps, to keep showing a profit to keep the stock holders happy, the big boys are gonna rise prices across the board. yeah, maybe just a couple of cents per item but still. so now you're effecting everyone. me, personally, double; as i own a small auto shop. due to the cutthroat nature of small business auto repair, higher prices means less profits. so now who's out to get at who.

karma will always get ya. that is all.

For once somebody else but me understands the whole core idea 8) But i do have to agree with runnamuck on this one and they will not accept as a core as it is a different motor. :t:

Some people really SHOULD just use a chevy motor in their jeeps since they can't understand what "Its broke.. rebuild it" means. When the 401 breaks are you just going to ignore it too? 111!!!.
