Someone makes an oil line kit to fix the prob with the one rear main that gets starved for oil.I hade one of those lines and like a fucktard I sold it.

Yeah, I made one up for the '70 360 that I put together a couple years back. I'll be putting the galley by-pass line in every AMC V-8 that I rebuild. Anything that I might race will get an external pickup and maybe even one of these: http://www.bulltear.com/catalog/product ... fa2c29af1d

I know ya' don't like Jeepers, Bart, but I think he may be putting out some decent parts.
Hey Spud, what do think of that part in the link?

Oh boy.....the infamous internal oil line. My current 360, that gets BEAT on, does not have one, and the bearings are still where they belong. For most of the engines out there that have it, all that line is, is 2 un-needed holes drilled in a perfectly good block. The thing is, when an engine that has it goes sour, what do 'ya blame then ? Clearances ? The assembler ? The fact of the matter is, is that it's one or both of those 95% of the time.

I know you have done a quite a bit of racing, and know your motors. However, just about every AMC engine failure can be attributed to the rear mains starving for oil. Maybe today's superior oils negate the AMCs notorious oiling system?
I wanna go racing in the spring, and I'm a little nervous about doing it with an AMC, I've ran them on the street for years, but never serious or semi serious racing.

To not start yet another endless thread on a subject that hes been beaten to death, I'll just say I disagree, and leave it at that.

It's a waste of time trying to generalize what kills off amc's, but I'd go way out on a limb and say a lot of the time it's just plain stupidity. and that transfers to the other makes too. watch out for stupid. it can waste the best engine in the world.

Well, whatever Spud recommends is what I would go with.
On the subject of engine failure, I was looking at some old SCCA T/A results. There were alot of DNFs by all makes. Just from looking at the race results, it seems the Mopars had more engine failures than anybody. Also, if there was a race where an AMC or two had an engine failure, there was always at least one of each of the big three there with a similar failure.

I agree. Too many X-perts that aren't X-perts at all.

Is GB even hangin' out here these days?
I'd like to see the particulars on his motor again.

..Then I shall retract my comment on myself being a 'fucktard' then

i believe greybeard doesn't run an extra oil line, he's told me bout his engine some, and if i recall correctly the only mods he's made are extra oil drinback holes in the lifter galley, and he grafted a mopar pickup screen in place of the amc pickup. I think he may have modded the pan. I think thats all. when I built my junkyard 290, I didn't do anything to it. it's all stock, except for the oil pump, which has been modded with ken parkman's trick. it has turned 6000 and more plenty of times and hasn't blown up yet. also it has crower mechanical lifters which limit oil loss to the rockers. greybeard also runs mechanical lifters

A buddy of mine did that. He says it helped with oil starvation at the big end of the track. He also worked the returns in the heads.

holy crap when you start yappin bout oil mods yer liable to hear so much bullshit yer dam head will start hurtin. folks have come up with the damndest stuff in the world to fix this or that. I figger unless your gonna try your hand at road racin, you probably don't need to much. klvn8r sent me this picture of an aussie who roadraces this javelin, and his block had about everything you could think of done to it. I say fuckit I'm glad I'm just a street/drag type and I probably don't need anything but a little too much oil in the sump. think i'll save my senses for something else.

What about using one of those engine oil pre-chargers or pre-oilers. I really don't know the correct name for them, but they pump up oil pressure before you hit the starter so you get full oil pressure everywhere evenly at cold start.

I might be mistaken, but the only guy I know who really seems to have addressed this problem who owned an AMC Dealership. He said the problem is the rear main is so far from the oil pump and is the last to get oil pressure. He cautioned about using the wrong oil filter which can lead to oil drain back and cause more dry running than normal. Basically, if you use some sort of oil system pre-charger system the problem no longer exists. Having oil pressure throughout the engine before hitting the starter makes more sense to me.

I noticed that some of those less expensive oil system pre-chargers are gravity fed. I don't see how those can work very well. I like the ones that hold oil pressure and then release it when you turn on the ignition. On those you can see the oil pressure go up while the engine is just sitting there. I've seen many on E-Bay that release oil pressure sold under many brands. I believe I saw one for sale at Jegs once if I remember correctly. Those are easy to install. Or am I missing something here?

No different than any other engine.
