410 build up

[flareside_thunder]

I thought moly rings took longer than 1k miles...I can ask my buddy tomorrow..he's an engine builder.

Alright Ive just been wonderin how long they usually take.

 

[flareside_thunder]

He says he seats em up before even puttin any mileage on em. But he said if you've already got it runnin and you've got a little bit of smokin goin on to drain the water and let it run for 30 seconds-1 minute at a time for three to four times with 45 minutes cooldown periods and that should let em seal.......Like i said he usually seals em up before they get miles on em then the break in is 500 miles.

Hmm alright ill have to try that and see if itll work if not then guess well tear it down and put some regular cast rings in it. Thanks Junior.

He told me he's never had problems doing it either way........

I talked to dad and he said that lets just put a couple thousand miles on it and see if its still burnin oil or not.

Found out last night that its been slowly eatin the lifters from the start and it ate clear through one last night so today I pulled it down and found this. This is also why it hasnt had very good oil pressure.
The one on the far right is the one it ate through. The rest are all different hieghts.

Heres whats left of the one it ate through.

Heres the guts of it.

So we ordered a 272/282 edelbrock cam and lifter combo but dad dont wanna trust em so we also bought a set of Rhoads super lube lifters. I think this is all from not usin a break in oil on startup. So to fix that we bought 7 quarts of royal purple break in oil along with a high volume oil pump and pan gasket.

Got the lifters, oil pump, oil and pan gasket yesterday and the cam was supposed to ship today so probly gonna be puttin it back together next weekend.

good luck!! keep us posted!

 

[1985 Ford F-150]

Yep will do.

 

[F 150Cobra]

Yep will do.

those lifters do look nasty tough.. what happend!?

 

[1985 Ford F-150]

I think it was because we didnt use break in oil at the very start. We used rotella 15w40 and thats supposed to have enough zinc and stuff in it that ya dont need to run break in oil, apparently it dont so we ordered 7 quarts of royal purple break in oil to make sure we dont have to do this again.

ahh ok .. im using castrol 10w30

 

[1985 Ford F-150]

Well itll go fairly quick if its gonna go. I dont know enough about roller cams so the only way to see is to put miles on it.

got about 15 miles on it now

 

[1985 Ford F-150]

That one went at 400 miles and I think that its been slowly eatin the lifters since we first started it.

did you guys do the 20 min at 2000 rpm cam break in ??

 

[1985 Ford F-150]

We did 20 minutes at 1500. Thats what our book told us to do.

ohh ok .. strange.. that happend what happend to the lifters :S

 

[1985 Ford F-150]

I dont know maybe cheap lifters from Comp cams. I read somewhere that the lifters now are made of softer metal since the late 80s. I think that combined with the oil companies takin the zinc out of the oils is whats makin em eat lifters and cams.
