Great, it's runnin again!

Ok, well, .... EGR, You CAN just block it off for now, rule it out, ya know? I mean, Hot Oily Back flow can't make it to the plenum via the EGR if the Plenum/EGR port is BLOCKED OFF, ya know? You could clean it out... .Depends what you mean on 'can't blow air through'.... You should be able to blow air through the lil tube on the neck, out through the bottom/head side. But I'm not sure you're supposed to be able to blow air through the top, out the bottom, or vice versa, ya know?

 

Oil in the intake could have also been blow back due to the bad seals, seats, guides, coming in through a PCV or Breather...etc., .... so it's hard to say.

 

EGR only comes on at higher power levels. Could be some trapped oil, you have drive it like you stole it to burn it all off and get the stink out. EGR is closed at idle.

Oh and make sure the PCV is in and hooked up.

Oil comes from rings and guides, and you've done them and more.

 

Ya I put a new pcv in it when I rebuilt the motor, and I drove the rig about 35 miles yesterday and it wasn't cleaning up at all, I'm just out of ideas

 

It's the worst if I let it idle for a while at a stop light or something and puts out a huge cloud when I take off

 

Geez, that does sux. I am sure you put the piston rings on right, you cast iron top ring & 2nd, your oil rings should have been fine, the guides were done & new seals installed.

And its still blowing clouds of blue smoke...........

So oil is getting drawn into the combustion chambers and burned; somehow.

Why do I want to think vacuum to something with low pressure on one side and oil on the other...........

 

I just kinda think its vacuum related, coups the problem be caused by not enough manifold vacuum

 

Wow, I'm really sorry to hear that, Rocker!

You can probably systematically rule out any pull by vacuum, etc., to get to a point where you know either know it is or isn't the rings/lower end.

If you rule out everything but bottom end, ... would you consider asking Tod or some other OR engine purveyor if they might have time to just pin down exactly what it is.... And, if you need to get into the bottom end at all cuz of a failed couple rings, etc.,.... would you pull it out and re-ring it, etc.?

Skypilot.....

I tested the EGR on mine, extensively, especially when we couldn't find my bad miss, etc.(which ended up being the CAM, bad build by that machinist, etc.)...... Down to the BVSV, Modulator, 3 tests on the EGR, including vacuum pump, etc.... So yeah, thinking on it, you're right with the '2200rpm' points... But is it possible that, if the diaphragm failed, every time he's cruising around, he's pulling in oil vapor through the EGR via the head, into the plenum? (Thus, the pools of oil in the intake channels?). Not sure why it would be so much oil, rather than just Crank Case Ventilation.... but......

Just for S&Giggles, Rocker,.... can you loosen the two bolts off the EGR to plenum port and insert a Silver dollar size piece of Coke Can aluminum, snug it down, and then>>> Drive it around like that, for a good 30-45 minutes, to let the intake valves pull in anything remaining in the intake channels, burn it off, then see if it's continuing to smoke at idle?

What else, guys, if anything, could be pulling in oil to the plenum? Or is there another way(crack somewhere, etc.), that oil could be making it into and out the head? I would think anything lingering in the CAT(if he has one) and such would have been burned off within 30 minutes.

Can you do/have you done/ a leak down?

 

Not sure..... The only results I've had due to clogged vacuum ports, etc.(in the plenum for the most part) was the rig would run a lil more rich/lean.

Have you checked/tested the manifold/otherwise vacuum via the plenum, EGR, etc.? I believe it should be from 15-22".... I'd have to look it up.

 

I think I need to do a leakdown test next.....not sure how hut I know I can find it somewhere online......maybe ill try and do it tomorrow, I'd hate to have to pull the motor again, but at least I'm getting good at tearing this truck down lol

 

You'll have it yoinked, figured out and DONE, DRIVING, in no time, now! Don't get me wrong, I HOPE it's something other than bottom end, ....but you NEED to rule it out, Rocker, ya know? That's why I was so pushy on that when you were tearing the head off, lol. I'm sorry it might be coming to this...but doesn't the 'NOT KNOWING' suck and drive you more nuts than ANYTHING? lol.

I've posted that link for many on here.... Here's one....

 

I had the same thing happen to my old 22re and found out it was the head gaskets.

 

ok, so i built a leakdown tester and am going to check that out in the next few days, but for the mean time until i figure out my problem (which i think i may have a crack somewhere in my block) i picked up a good running used 22re complete with all the fuel injection and accessories basically ready to drop in for $400, so at least it gets me on the road for now, then i can tear into this problem child and hopefully find the issue, lol

 

WHAT THE EFF!!!!! ha, i cant believe you found a good used 22re for $400...nothing in sight down here for less than a grand....good find man, for sure.

 

ya, i think i kinda scored, im not giving up on my rebuild, i WILL find the problem lol, but the $100 bucks a week im spending driving my diesel is breaking the bank, so at least this will get me on the road for a while.

 

I hear ya man...I was borrowing a friend of mine's gmc acadia...12 mpg in town sucked butt. glad to be back in the yota...at least if it gets poor fuel mileage, it has a good excuse....ITS OLD!!!!!!

 

Great attitude, Rocker! I know you're probably flustered.... but it's a machine, and IT WILL NOT BEAT YOU! hahaha.

Cool, .... found a good thread on the leakdown(Make your own) angle?

 

PS> ... GREAT DEAL on that, 400$, especially if it's 'READY TO GO'! lol.

Maybe slap your newly rebuild head on that block, swap over all the known good sensors/oil sender/knock sensor, etc. from yours and be done with it for a while? Then, tear into the short block you have in there now, taking your time? That the plan? Or you're leaving it complete, not wanting to tear off the head and have to deal with another HG again, etc.?

 

well the guy i got the used motor from gave me a 30-day warranty on it so im not going to do anything to it except put a front and rear main seal in it and some spark plugs, and im putting my manifold and injectors on it because theyre in better shape and if it smokes or runs crappy, then im gonna get my money back, lol.

 

THAT'S GREAT! Ok, Mani and injectors... but leave the head alone, right? Gotcha!

BEST WISHES, ... report back as soon as that thing doesn't smoke a LICK! lol. Tellin ya... I still, like from early on, think that block has a major issue in the lower end(could be a minor issue) that's causing that smoking... 190# compression or not, SOMETHING is wrong, right?
