NEVER!!!! :D

Not true!!!

When we have a dumper blow through and leave us up to our necks in snow, we will know that spring has arrived. :)
 
update -- virtually 0 preload on the lifters -- that 0.1 short in the rods appears to be the problem. Should have some stock rods today, will test the preload on them, and maybe fire her back up this afternoon -- crossing all available digits....:wierd:
 
So, the rods were too short? Musta bent from the light constant hammering then?

Ya learn something new every day......

Apparently - as Adam J (the PO and original builder) pointed out above, he ended up with shorter rods during the build, to the tune of maybe 0.1 inches. Best I can guess is that I had no preload, so when not under pressure, they could have bounced around a bit, like out of the cup seat on the lifter, resulting in the bneds :dunno:

I spent the better part of the afternoon chasing stock rods around town and sitting in traffic due to the ineptitude of the parts monkeys at Advance, so maybe tomorrow will be the da!:peace:
 
I'm still putting even money on the lifters being pumped up and not compressing.

Unfortunately, while the rods are definately short, I tend to think so too... It is really tough to tell if you are getting any movement out of them in the engine (by hand), given that we're talking about 0.02 of movement... I have a hunch that the head will be coming off sometime this week. Again.:lickout:
 
I've got some vinyl tube if you want to try sucking some of the oil out of the lifters with your shop- vac.

Thanks Frank, but I convinced myself overnight that if my pre-load is even iffy once I get the new rods in, I'm pulling the head, inspecting/relieving any hydro-locked lifters and moving on -- I really don't want to fire it up with new rods only to bend them too with effectively solid lifters -- I'll do it right and do it once (I hope), even if it takes my another 2 weeks at my wicked quick mechanic work pace...:roll:

Also, Adam checked his old emails and found his originals from Accurate Power (amazing, we're talking email from 6-7 years ago) -- the rods I took out were 0.045 short -- my stock ones should be moving me back towards the proper spec (assuming that my incompetent ass is even remotely close on measuring preload, which is definitely debatable...):hang:
 
update: Frank and I gave her a couple hours of attention on Sunday, essentially double checking the pre-load measurments I had made, making those measurements with the new stock pushrods. We calculated about 0.1 of preload, so we shimmed the rockers @ 0.06", re-assembled and fired her up: noisy.

So, we pulled the valve cover and some of the rockers were silly loose, even though properly torqued -- unshimmed the rockers thinking the noise may have been these rockers bouncing around. Rockers properly torqued were still a touch loose (could wiggle them slightly with pressure), but much tighter. fired her up - still noisy.

nothing in the upper valve train appears out of whack, so I'll be pulling the head (again), pulling the lifters, manually bleeding them (disassembling if necessary), re-installing and seeing where we go from there... :rattle:
 
Man, you've gotta be pretty friggin' sick of all this trial and error crap Chris..... I don't know how you're doing it.

I wouldn't have to go to my tool box to get a wrench - I'd be pulling 'em from the garage walls they'd have been thrown at....... :D

How am I doing it? Pretty friggin slowly, even by my standards. Not sure what other choices I've got at this point - $1k in the rebuild and seemingly pretty close to running, gotta figure out WTF is up with the noises... I did threaten to call Stang and discuss 5.0 swaps with him this weekend, but I don't think I was serious... yet.:cheers:
 
SOOOOO, 10 of 12 lifters appear to have been hydrolocked - no movement in the caps at all under pressure. Disassembled all of them, and now have the more typical 1/8-1/4" ish springloaded movement. Each lifter had at least a 1/2 teaspoon of oil in the bottom which would not bleed out, even upside down, and apparently was causing the hydrolock... picking up some new head bolts (set 2), new head gasket (#4) and oil change supplies, and putting her back together, maybe even this weekend... cross your fingers, toes, and any other digits you are able to cross (without excessive pain)...:confused1:explosion
 
given.
 
I made them "bad" with pre-soak and pre-prime...we'll see how the pre-load looks this week. My sister was in town for the weekend and my head gasket won't be in until tomorrow, so no sunday progress report...:peace:
 
Aaaaaaaaaaaaaaaand... she runs.... she knocks.

I put it all back together today, checked lifter preload - appeared about 0.05 - within spec. I reassembled the accessories and fired it up and have exactly the same knock. It's official, I give up. I have too many other things not getting done while I try to fix this by braille, and I'm man enough to admit that it is beyond me -- I'll learn more at this point from a pro telling me what it is that I actually fooked up. :rattle:

I have a mechanic that does a bunch of automotive work for co-workers that I may take it to, but sure would appreciate it if the springs guys would chime in with any recommendations for a quality mechanic that won't break the bank. :helpme:
