Oil Slinger ???

[Jack_440 Savoy]

I was just putting a Nice New Shinny Timing Chain Cover I got from "440 Source" on my 440. I Noticed There was No Oil Slinger !!! Any Good Reason for Not Putting One on after a Rebuild Other Than Someone had TOO many

[dwc43]

You don't need it. And if it has a double roller chain, there's no room for it. All the police car engines have double rollers and no slinger from the factory.

[moparmarc]

I'd bet the most popular reason for not putting it in is you've got the whole thing buttoned up and the pulleys installed, then realize you've got one part left in the box. Whoops.

[rumblefish360]

LOL @ Marc. Been there done that...ops!

There correct. It isn't a mandotory item to install. Helpful? yes.

When I rebuilt my 440 a good friend of mine told me that when he rebuilt his engine, he forgot to install the oil slinger and had oil leak problems with the front crank seal. So he pulled off the timing chain cover and installed the slinger not having any problems after that. He told me to make sure and install mine during my rebuild. I installed the slinger with a Mopar Performance double roller timing chain and had no clearance issues. Perhaps other timing chains are different? I would say that if you do have oil leaks after you get the engine started, then you probably would want to install the slinger. But who knows, maybe you will get lucky?

Well, It does have a double roller chain and it wasn't leaking before. When I put the New Seal in the New Timing Chain Cover I put a little RTV on the outside metal mating surface and finished it off with a small bead around the seal after it was in. And NO I Didn't put any RTV on the Neoprene Seal , Only a little start up oil .

I've pulled apart motors with lots of miles on them, and no slinger.

Don't worry about it.

[Jack_440 Savoy]

OK, So the main consensus is "forget the slinger" Now Here's another one for you, I am using a electric fuel pump. Can I ditch the fuel pump actuator rod ???

I just built one with a double roller and had no problem installing the slinger? What do you mean "no room for it"

I always use it. I can't say that it has to be used BUT I have never had a front main seal leak.

Just my $.02

I meant as there is no room for it. It wont fit. Even the stock police car engines and Little Red Express trucks that run factory double rollers do not have one. THey hit the chain on my cars so the slingers hit the trash. And I don't have leaks either, so they are not needed. THey might be o.k. for a high service milage type car. Taxi.

You can toss it with no problems.

[The_Dakota_Kid]

i have been running one in my double row chain big block tha past few season, On another note, I have left them out with no ill effects. If you want to pull the fuel pump pushrod you can but, leaving it in wont hurt....at least it wont be misplaced.

I’m still not sold on the whole omitting parts from an engine build. My 1969 Plymouth Service Manual shows both the removal and reinstallation of the oil slinger on not only the 383 and 440 engines, but the legendary HEMI as well. I suppose it may be a simpletons approach to looking at things, but if Chrysler engineers saw it fit to engineer such a part and put it into production, then I think I’ll go ahead and reinstall it back when I’m done even though the masses tell me there’s no reason for it. This kind of reminds of other debates I’ve heard before… Remove the 904/727 accumulator spring!?!? Reinstall the 904/727 accumulator spri

If you havent got room for the oil slinger you must be putting it in backwards! They fit in all the big blocks with single or double roller chain setups. Stop and think about it. They are sandwiched between the crank sprocket and the harmonic balancer. Does that sprocket make your crank pulley stick too far forward? Of course not! Are they an absolute necessity? Probably not, but their sole purpose is to keep as much oil as possible from directly contacting the seal so it won't encourage it too leak. I never put one together without a slinger, but that's just me and my .o2 cents worth........djs

[70Ted]

it was band aid for a poor seal.

[dwc43]

On some double roller chains they will not fit. They hit the chains and will rub the rivets right off of the chain. You wont find a one in any of our small block race engines. If you try to install it, you better check your clearances. It was used to keep hot oil off of the seal so it would last longer for high milage use. It's up to you, but you really don't need it.

[43 purestock]

You wont find one in dws motors, because he has NO race motors. Its there for a reason, put it in there, it also helps sling oil around and get oil to the chain and gears.

[turbododge]

The newer seals are better than the old ones and won't leak for a long time, but having a slinger is a good idea because any seal can be overloaded with oil and leak, especially when they get older. I have not had any trouble on my small blocks with double roller chains and the slinger and have run them many miles without issue. As was said, necessary-no. Desireable-I think so. And hot oil is not going to do any damage to the seal. Slingers are used so the seal does not see as much oil as it would without. All seals are made to allow a little bit of oil by, if they didn't they would burn up. If you put more oil on it than it normally would see, more will go through. Bottom line is that the amount is still very small and most of our engines will not see enough miles to wear the seal enough to know the difference.

The only time you will see big difference would be in an engine that gets high crankcase pressure, like a boosted engine. In that case, the slinger will reduce the leakage.

After all NOBODY said they did any harm...... :an

Hey DW, before you say there is no room, you need to look at a B/RB engine, since that is what this is about. If he were talking small block, I would agree with you. The fact is, he is NOT talking small block, he is talking about a 440.

Ran into the same thing on the big blocks too. Slinger rubs on the chains.

[ehostler]

Yet, no one else appears to have had this problem on a big block.

[BELVEDERE2]

My 318 rattled like hell with a dbl roller. Just removed the slinger. My friend runs a 440. No problems. Maybe it is just the small blocks.

[TK]

Thats BS, I have a 318 outside with one on it, and a Cloyes roller chain, your crazy.
The 360 i built fo rmy race truck, has one too.
And so soes every one I ever built, that came off with one, well, actually, I forgot it on Gramps 440 last year, don't tell him, he is on his way back from Idaho............

[TK]

No problems. Maybe it is just the small blocks.

Well, it may be the brand of chain ro something too.

[dwc43]

That would be my guess since we can't use them on either engine size. Like I said, it's not really needed and has never caused a problem since we stopped using them.

[TK]

What brand of chains?
