$50 Craigslist 360 EXTREME budget rebuild??

Before you fire the engine make sure that you have the zinc stuff in your engine oil --> will definitely help during break-in to protect your cam and (flat tappet) lifters.
 
Use a heavier weight of oil and it will likely have more zinc in it; the lower levels of zinc and phosphates and such were EPA mandated in the lower oil weights, like those at 30 and under.

How much of a problem is low ZDDP levels for stock springs and an already broken in cam? I dunno and I am not sure anyone knows; the low ZDDP issues seem to have been linked to new performance cam break-in issues. The levels in the lighter oils have gone to 600-800 ppm versus 1000-1300 ppm previously, so it has not totally disappeared. Pre-60's engines ran fine with flat tappets and the older springs and lift rates and so forth before the ZDDP levels went up in the 60's or thereabouts, so there is a threshold of lifter to lobe pressure above which is it is needed. So it may just be a matter of better-safe-than-sorry for this build.

I suspect you can put in the additive after priming and things will be fine. And yeah, it won't come spewing out the timing cover hole.
 
This is my point for askin why?? Same low lift cam and lifters thats been in the motor for the last 35000 miles.

never quit protecting the cam/lifters. I add ZDDP Maxx to a couple of my flat tappet cars, and one I have on VR1-10w-30. I never quit protecting.

^^^^^^^^^^^^^^^THIS^^^^^^^^^^^^^^^^^^^^

These engines always need phosphates zinc. Even with roller cams but flat tappets need more of it.
 
When I owned my Stingray, I didn't know about this....
Drove it and did oil changes with regular oil for 14 years without ANY problems. ...
I would NEVER do that now....:thumbsup:

Yes, Jeff. A while ago, I actually called Valvoline themselves, and talked with their tech. They said if a car with flat tappet cam already has, per say 50,000 miles on it, it should survive without special oil/additives.
Not the way to roll, though. Years ago I would just go to Advance Auto Parts and pick up a bottle of Rislone (oil treatment and added zinc for flat tappet cams) and pour half a bottle into an oil change to the cars that had thousands of miles already on them. For 8 bucks, I got two oil changes worth of protection.
 
Are you guys saying I could run the risk of flattening this crap unknown cam and lifters and run the risk of having to get something better? Oh the horror! :poke:
 
this morning a lot more of the push rods are clearly looser than they were so that's actually a good thing. I've got to keep the extreme budget in mind here extreme budget extreme. Yes I got to keep saying it to myself so I went to Walmart and got two Walmart oil filters, 5 quarts of oil 10 30 weight Quaker State and that's what I'm going to use. two and a half quarts almost 20-50 GTX one quart of 5w40 Rotella synthetic and almost one quart 15-40 penn grade to get things started with a filter change. Maybe I can get the priming started by pouring the pen grade in first? That will have the zinc?

I just thought of a good one I turn the motor on its side and fill the oil filter with the penn grade.
 
just keep in mind that the ZDDP is sacrificial product that get between the lifter and lobe.
its not something that stays attached. if you drain it. its gone. if you don't change your oil it will slowly deplete it self.
you probably don't need to worry about it......but i would.

AAAAAAAHH I get it NOW.... "Sorry Honey.... Some FOOL on FABO said it would probably be fine without ZDDP additives. That idiot...Sorry that we have to get a new cam now..."
Let me be the first: " You will probably be fine without ZDDP additives."
 
I think it would have been dumb luck that the guy before me had zinc additive oil the first 35000 miles
 
I've only ever had 1 cam go flat; that was version #2 of my "Mean Teen", it had been "stored" for future use......didn't think too much about it when I got it out of storage and fired it up, it had run before, it was broke in.........what me worry??? Well lessen learned is "don't take anything for granted" at fire up, whether first fire after new build or rejuvenating one that had been dormant.

As a suggestion.........if you don't have the intake on it yet, leave it off to do the following.......put what ever cocktail of oil and additives in the pan, oil prime the engine, then pour a bottle of STP (blue bottle, it has twice the zinc of the red bottle) down along the cam and lifters coat everything, then put the intake on and fire it up as quick as possible. I have had success with this method of fire up. If the intake is on then we'll all hope for the best.
 
Okay I'm having a hard time Imagining the motor running two months ago and now I take it apart clean it put assembly Lube all over it put it back together and it's going to wipe out the cam? I'm not arguing here I'm just saying...
 
I'm not saying you will............

Do you look down the barrel of a cocked and loaded gun to see if there is a round in the chamber?? Not saying the gun will go off if you do........

Lack of imagination is what killed the Apollo 1 astronauts...............

What, where, when, how you wish to do it, good luck!!
 
simple fact of life! wanta flat tappit cam to life you run ZDDP in ya oil! or go roller cam that dont need it! if you want a new cam bbuy one dont kill that cam just to justify buying a new cam! imagine all the fine metal cam particals covering all them parts you just cleaned!!
 
I think your entire answer is as high as the Apollo Astronauts ever got LOL

What the hell is this whole world went completely mad you mean I completely clean that cam and it's got cam particles still on it!

I think you will be fine without the zinc, a worn out cam with weak springs is waste of zinc. lol
