95 k1500 6.5 TD, OIL LEAK , also any help making it the best it can be
 

i recently just purchased a 95 6.5 TD wiith 242xxx on it. runs good haven't had a proplem yet, I hada new drive shaft put in ( came without one in it ) trans filter and fluid , oil filter and fuluid and this ait intake which I don't think Is correct, has the blue fsd relocate I think or whatever it may be. anyways I drove it on a trip about 2xxx miles total and it ran good. first leg was a night ride and the back trip was mostly day, around 800 miles on the second leg it ran hotter at 210 then I pulled over for fuel and she didn't want to start , so got her started , then checked all the fluids and smoked from the dip stick. haven't driven it much the passed couple days so I drove it a lil today ran fine, checked the oil theres like non in it. barely reads on the dip stick. any ideas on where its all going. heres some pics as well as the engine bay if anybody see anything out the ordinary please help out and tell me anything I shld do I plan on keeping the truck a while, thanks

Also here is a video link of the truck running on youtube

Looks like some blow by does the truck have a lot of miles on it. Do a coolant pressure check and compression test and see what you get.

Your cdr valve is probably plugged up causing the smoke to roll out your dipstick tube. Of course a good cdr isn't going to stop it from eating oil.

So I took off the cdr valve. Took a can of break parts cleaner an cleaned it out. Alot of gunk was in it. Wasted a whole can til the liquid came out clear . Hopefully it does the truck. Still doesn't want to start up . Takes a minute guess I got to burn all that oil out the intake I'm assuming

FWIW...

Crankcase Ventilation System

General Description
The crankcase ventilation system used on [GM's 6.5TD] diesel engines is designed to maintain a slightly negative (vacuum) crankcase pressure across the [entire] speed range. The system consist of a Crankcase Depression Regulator (CDR) valve, located on the right valve cover and the attaching vent hose/pipes to the engine [air] inlet system. The CDR valve is only used to regulate crankcase pressure between 0" and -4" water depression over the engine speed range. The CDR valve is NOT an oil separator or a crankcase effluent flow regulator. Hence, the CDR valve DOES NOT prevent oil droplets/mist [vapors] from entering the intake system, nor does it effect engine oil consumption.
The Intake manifold vacuum [pre-turbo] acts against a spring loaded diaphragm to control the flow of crankcase gases (Figures 11-1 and 11-2). Higher intake vacuum (or highintake restriction, e.g. plugged air filter) levels pull the diaphragm closer to the top of the outlet tube. This reduces the vacuum level from getting to high in the crankcase. As the intake vacuum decreases, the spring pushes the diaphragm away from the top of the outlet tube to prevent crankcase pressure from going positive.

CDR Valve Test
The purpose of the CDR valve is to maintain 0" to -4" inches of water vacuum in the crankcase at all engine speeds, assuming that piston/ring combustion blow by is not excessive (less than 4cfm). Too little vacuum will tend to force oil leaks.
The CDR valve is checked with a water manometer. The U-tube manometer (Figure 11-3) indicates pressure or vacuum by the difference in height of the two columns of fluid.
If crankcase vacuum is too high (greater than -4" water), dirt or dust can more likely be pulled into the crankcase cavity(pulled through front/rear crankcase seal, etc...) and contaminate the oil. If crankcase pressure is positive, engine oil leaks are more likely to occur around engine seals and gaskets.

1... Connect one end of the manometer to the engine oil dipstick hole. The other end of the manometer is vented to atmosphere.

2... NON TURBO- Disconnect CDR hose from CDR valve in rocker cover so valve can vent freely to atmosphere.
TURBO- Unplug rubber vent tube from turbo inlet elbow.

NOTICE: Do Not allow any foriegn material to enter inlet system where CDR valve vent hose has been disconnected.

3... Run engine through no load speed range (gear selector in park) and observe manometer readings. If manometer reading is +4" water or less positive pressure, reconnect CDR system and proceed to Step 4. If manometer is higher than +4" water positive pressure, refer to Section 6A ["Engine, Driveability and Diagnosis"].

4... Install air cleaner.

5... Start engine and observe manometer reading. It should read zero to one inch (0-1") of water (vacuum) at idle to approximately 3-4 inches of water (vacuum) at 2000 RPM.
Add the amount that the manometer column travels up, to the amount that the column travels down to obtain total water pressure (vacuum). An example of a manometer reading is as follows: One-half inch above zero plus one-half inch below zero equals one inch vacuum reading (1/2" + 1/2" = 1") (Figure 11-3).

NOTICE: Do Not allow any solvent(s) to come in contact with the diaphragm of the crankcase depression regulator valve, because the diaphragm will fail.

The crankcase depression regulator valve is replaced as an assembly. Replace hoses as required, if inspection indicates cracks or decay.
Refer to Section 0B in appropriate service manual for diesel crankcase ventilation system maintenance requirements.

Section OB- Maintenance and Lubrication- To paraphrase..
As an emissions control device, both Maintenance Scheldule I and II call for a "CDRV System Inspection" annually and/or at 60,000 mile intervals.
