It's always something!
 
Well here is the story: I picked up a Camden, so the Turbo Setup I had came off and car sat for two weeks while i worked on it. I Installed the Camden today and fired that bad boy up. Smoke started pouring out the ass. People, we're talking bucket loads! See the pics and video.

The question is: How the hell could an oil control ring go bad from sitting? It's either that or the Camden is having some blow by into the rear rotor. I ran the damn thing without the oil feed hooked up and she still smoked. WTF? It's always something! Please feel free to chime in with input!

Camden turbo???

yetterben 06-05-08 11:11 PM

had a turbo setup took it off to check out camden!

Jeff20B 06-05-08 11:51 PM

Well mine smokes a little but not like that (it's the engine).

Is it possible for you to install a stock intake manifiold and carb and drive it around for a while to clear the oil out of the exhaust system? This will prove to everyone which part is actually leaking.

Also if you swap intakes like I suggest, look inside the Camden manifold for signs of oil leaking. A little oil in the manifold is kinda normal (I've seen it in two or three Camden manifolds during engine swaps where you have to pull the SC off the manifold to more easily remove it from the engine bay).

yetterben 06-05-08 11:53 PM

Jeff the oil is only coming from one rotor. The other is clean and dry. I have a feeling its the oil control ring.

Jeff20B 06-06-08 12:04 AM

So it's not the Camden then? Sounds like it's engine rebuild time.

yetterben 06-06-08 12:06 AM

Sounds like i am selling everything off and going back to ls1 power! If the camden was pushing oil in it would be on both rotors i would think not just this one. Car stars right up and revs awesome just makes massive smoke. I lost half a quart in the driveway in 3 hours so pretty sure it oil control ring.

Jeff20B 06-06-08 12:23 AM

I would think it would be in both rotors but if only one seal inside the camden leaked, say the rear seal, most of the oil would tend to flow into the rear rotor since it wouldn't very easily travel horizontally, let alone slightly up hill, as the engine does have about a 6° tilt or so.

I hate V8 swaps but you gotta do what makes you feel good.

One thing I wonder is why so many piston swapped RX-7s go for sale so often... if it was such a great swap, why does the owner sell it... cause the only things it has going for it is the quick take off ability of tip-in torque and the V8 rumble, but then it leaves you wanting as the RPMs climb? I guess I'll never understand.

yetterben 06-06-08 12:27 AM

No i mean jump ship period and go back to f-bodys for ahwile or something. SEe i let the motor cool down for an hour or so removed the oil feed line to charger and belt and it still smoked i only let it run for about 5 minutes until the temp needle started to move then shut it off!

yetterben 06-06-08 12:41 AM

maybe it is the camden when i pulled it off i noticed this oil in the charger i did not completely remove the unit just slid it to the side. I will remove the whole unit tomorrow and check for sure. But the oil that was in there was mixed with gas. Check out the pics. I hope it is the camden man that i can fix. I If it is the motor i just dont have the cash to get a rebuild unless i can score a block for a few hundred. Before i remove it again i will fire it up and let it run for awhile so its nice and smokey remove the camden and see if the oil is only localized to the rear rotor in the intake.

Let us know how it goes.

yetterben 06-06-08 12:48 AM

Does that look like too much oil jeff? Now that i think of it that shit is pretty dark. And if there is that much of a steady flow like whats in there i suppose thats enough to make it smoke like a mother. IT does get worse with the revs

Jeezus 06-06-08 12:48 AM

I would say remove the SC and run it NA for a while and test it. The SC is basically draw through, so it is no major concern to the engine (besides the pressure it makes) if you run it with just the carb.

My 2cents, run it NA, with a Nikki or whatever carb you have on it right now and see if it smokes. I run a 600cfm holly on a stock port, so whatever you run should be smaller :D

If it still smokes, it is engine. If it doesn't, then it is the camden :(

Jeff20B 06-06-08 12:58 AM

It's hard to say. I've seen clean oil sitting there but I'm not sure how it compares to yours because dirty oil is a lot more visisble than clean.

Just swap in a Nikki and drive it around for a while to burn off the residual oil in the exhaust. Then you'll have your answer. :)

yetterben 06-06-08 12:59 AM

here is a ? for yah though why would crank oil be in there at all i run premix idemitsu 100:1 so something has to be leaking oil in there regard less.

84stock 06-06-08 07:38 AM

Problem is he doesn't have a stock intake to bolt on and test (swapped his turbo setup for the camden). I pm'ed this advice :.....Clean out the intake, disconnect the ignitors, and turn the engine over with the oil feed hooked up to the charger. Do this a few times letting the started cool each time. (turn off the fuel pump), you don't even need the carb on the charger or have the charger bolted down tight. Now, pull the charger off and inspect the intake for oil. The "only" place this oil could come from is the charger. Feel the inside of the charger at the bottom back and see if there is oil. Inspect the rotors as well. If the charger is leaking there should be oil inside. With no carb on there is no fuel to wash the rotors and any oil appearing cannot possibly be 2 stroke dropping out of suspension. When you lift the charger, keep it tilted back and then tilt it forward to see if any oil runs out into the intake from the back of the charger. Please test and respond, Gary......

yetterben 06-06-08 09:13 AM

Here is the deal: Did what gary said and there was pure sump oil in the camden even when i removed it to inspect. not mixed with gas same color as sump oil. Cleaned everything up left oil feed off and belt fired over engine. Small traces of oil in the exhaust very light. Car obviously ran like shit without the blower going but would think its enough for this test. Before smoke pored out now not so much at all. I guess the real test is to hook it up proper and see if it starts to smoke again!

yetterben 06-06-08 09:31 AM

now here is the kicker hooked it all back up was fine for a few minutes then it got progressively worse as time went on. i set the idle to 3 grand to watch what it did and it got thicker and thicker and thicker. Now when it was all unhooked meaning belt and oil feed it was very light granted i only let it run for about 3 minutes but i would think if there was oil the in rear rotor it would have started smoking right away!

yetterben 06-06-08 12:01 PM

Well if this does not say it all then i dont know what does. This is about 5 minutes after i cleaned it all out.:icon_no2: :icon_no2:

I am gonna bite my tongue until i call Atkins!

And that chunk of rtv fell in there after i removed it!

Only place this oil could come from is the blower!

Jeff20B 06-06-08 12:06 PM

It would have smoked right away had there been oil in the rear rotor so you are correct. It takes a few minute for the exhaust to heat up to start burning off oil inside. You'll also need to take it on a hard run to heat the exhaust up more to burn off everything.

Too bad about the Camden. At least something can be done about it to stop the leak inside.

yetterben 06-06-08 12:09 PM

Like i said i am gonna hold off on comments until i call dan or andy!

MODS PLEASE LOCK AS THIS IS NOW A DEAD ISSUE!

84stock 06-06-08 02:04 PM

Camden posts never die! I trust Andy will take good care of you, they are good guys.

yetterben 06-06-08 03:20 PM

Andy has decided to fix this issue for me for free! case closed lock stock and barrel!

Jeezus 06-06-08 03:34 PM

Happy ending :D
