It never pooped, just suspect. Found a few things. Tops of valves look like they spun around, on all valves. Is that a sign of float, or improper height? @NightTrain66 . Roller lifters had wear lines on the rollers, not like a flat spot, but a line around the roller as it spun
Got ya. Can you still post the bin?
Pull the damn heads already
Diiiid someone pop a gasket?
Doesn't look like it, no coolant in cylinders, smells like fuel in chambersQuote:

Last pic no flash
No smoking gun to be found. Guess it was just blowby, possibly on the valve seals as well. Oh well. Gotta ask elliott about the valve tips and see if its normal. Cylinders still have cross hatching
You'll have to pull the piston out of the bore to see for sure if a ringland is cracked.
Pistons do look pretty clean. Any marks on the bores?
Just some crosshatching. Will pull pistons carefully tonight. If nothing is found, I'll probably use this bottom end for the impala to speed up that process. For whatever reason it looks like the pcv catch can wasn't doing a damn thing.Quote:

When we put that blower on my friends car we had a lot of big puffs of smoke, the tune was adjusted and fixed the problem. Now you can just get that 383 done and in the car.
This thing definitely had blowby issues, the valve stem seals on the exhaust side were leaking. Oh well.Quote:

If its puffing smoke like that from a crank case breather Iwould say bottom end is wounded some way.

Already pulled pistons, no cracks, bores looked good. Motor is becoming a 383 anyway. My question is about the exhaust guides having oil on them inside the ports. Also, the rotating of the valves and the valve tips having marks on them. http://tapatalk.imageshack.com/v2/15...6ed74265a2.jpghttp://tapatalk.imageshack.com/v2/15...198814b2e9.jpghttp://tapatalk.imageshack.com/v2/15...42c3554f10.jpgQuote:

What cam was that in the car?
What lifters?
What kinda preload?
If thiose are the LE1 heads that you bought from me they had 165 lbs on the seat for your boosted set up and that should be fine unless they are Comp R lifters, rockers too tight or a cam with real aggressive lobes.
160-165 lbs on seat with good lifters adjusted properly should be stable to 7000 RPM with 15 psi of boost with one of the blower cams that we do.
As fara s the seals, I would think that it would make other gaskets (valve cover, oil pan, etc) leak a lil also if there is that much pressure in the engine to push oil past valve guide seals too but I am not sure.
Lloyd
Bullet 228/234 592/592 on on a 110lsa, ls7 lifters, 3/4 turn, scorpion 1.6 sa rockers (which the rollers look fine on). These were LE2 heads done under Goodman in 10/13, not LE1's. @NightTrain66Quote:

Once you add 10 PSI of boost you have 10 psi of pressure on the back of intake valves trying toi hold them open and that will eat up about 25 lbs of seat pressure.
More boost pressure would eat up even more spring pressure.
If the heads and the cam were not set up for a boosted set up (extra seat pressure on springs and slower ramp speed on closing side of intake lobe) floating the valves would be a DEFINITE possobility/probability.
As fara s the blow by causing oil to come thru the guides/seals, it makes sense that this could happen but I ahve never had a car with severe blow by diagnosed and tore down looking for that. Once the blow by was realized (broke piston, etc) the engine was always tore down an completely went thru so i never chased problems like that or looked for culprits.
Was there any oil pushed or dripped thru at oil pan, timing cover, valve cover gaskets, etc?
Lloyd
1/4 turn would help alot but that cama dn boost will want 175-180 lbs of pressure at 15 psi of boost.
Lloyd
No, nothing pushing out of gaskets, just the breather really badly. It only saw 7 psi. everyone had us scared we broke something since blah blah blah, but in reality, it probably wasn't a big deal. Oh well. I will be using that cam in my impala. Thing is, there could've been float before the boost from what you are saying. What springs am I going to need to handle it na? Those lunati's? Patriots? Etc.Quote:

The 228/234 .592/.592 lobes will need 140 lbs of pressure to remain stable with perfect rocker geometry, perfect PR length, perfect lifter preload, etc, The more these things are off, the more pressure needed to remain stable.
Add 7 psi of boost and that will eat up 14-20 lbs of seat pressure causing valve float if the spring doesnt have that extra 14-20 lbs of opressure to lose.
Springs can also lose a lil pressure also.
If the guides and seals were bad it would have had a lil puff of oil smoke out of tail pipe on start up and get pretty gunky in the ports and hedaers pretty quick. If thats not there then i would assume the seals were in good shape for a long time and just recently went bad if they are bad. Maybe the boost/blowby effected the seals if they are now bad. ???
There are videos of "valve float" on Youtube and you can see the valve stem doing crazy things and wear guides pretty quickly depending on how bad it is. Some of those videos are to the extreme and parts would break pretty quickly under that trauma in some of the videos but it does at least show what kinda stuff is going on even though it is to a myuch lesser degree.
Lloyd
email me a pic of the springs and I'll knmow what they are.
just have them checked to see what pressure they currently have and I would put them back at 155 lbs on the seat if they are not there now. that will be fine for that 228/234 .592/.592 cam N/A.
Lloyd
its the patriot duals, nice and shiny. ill probably be sending my heads to you for the impala. gotta get the trans first. so when ill do, ill throw a note in the tote to set them up for that cam
Just dropped the splayed 4 bolt 383 block off to Karl Ellwein, he is gonna work his magic on it. About to drop off the Camaro trans for upgrades and my trans to be built to @Cahall and say hi to the pups.
Great seeing you and Osie today. 1 update and one more Pro Race 4L60E on deck.

Pretty things. Karl said crank should be back tomorrow from balance, then ASSEMBLY!
