Stinky got his bloodwork back! (oil analysis report)

[Rat407]

Glad to see someone else has an oil report on a 1.6. I had mine done as well in my 91 ECO Jetta. I posted on BITOG.COM  Yours isn't to much different than mine except for the iron and since I have an oil pressure problem that I think explains mine iron.  Check it out here

I had the engine completely rebuilt three years ago this coming spring. I have an oil pressure problem, that being I have no oil pressure at operating temp. I get 20psi at cold start up but when the oil warms up it drops to zero and stays there. The gage is good as everything in the engine is new. That oil pressure reading is at the head. I have oil volume just no pressure. If you take my cam cover off you will get soaked by the oil that flows up there around the cam and lifters. Engine smokes on startup. The shop that did the head messed up on it obviously for the smoke I'm getting. I go through a qt of oil every 3k miles. Running a stock Mahle OC51 oil filter and a stock Mahle paper air. The injection pump has been rebuilt and tweeked so I'm getting plenty of fuel. If I run up the RPM's with about 15PSI of boost I can get a nice black cloud of smoke. Needless to say nobody tail gates me. I get lifter tap, some days bad and some days not at all. I figure it is from the oil pressure issue. I just turned 20k total miles on the engine since I had it rebuilt. It was broke in on Rotella SAE 30 for the first 500 miles and then 3k after that and then 15w-40 rotella at 3k miles up until I put the AME in. I always run a Mahle OC51 oil filter. I had the K14 turbo rebuilt when I did the engine and I installed a 2.5" down pipe off the turbo and it runs 2.5" all the way back to a flowmaster muffler. My best fuel mileage has been 52.7mpg. On average I get 46-49. This sample I have ran about 14 gallons of waste veggy oil mixed in with the diesel at a 50/50 mix. It sure seemed to like that, ran smoother than on regular diesel and smoked less. That is about all I can think of for now. Again, comments welcome.

Do you have an oil pump for a mechanical head installed on a hydrolic lifter head?

No. I changed the pump out twice just in case and it is for a TD.  I'm thinking there is an issue with the head its self. Something with the casting. From reading the previous owners maintenance records all was well with the car up untill he broke a timeing belt and had the head replaced at 110K. Then when the car was in for maintenance after that for what ever reason the service department noted a few times on the oil pressure light coming on but the oil level was full.  I have oil flow/volume just no pressure. If you take the cam cover off you would get soaked from all the oil up there around the cam.

the pump is for a TD, but there is a huge difference between the hydraulic pump and the mechanical pump.   the hydraulic lifter engines require a bigger pump to deliver more oil.  if you have the mechanical lifter oil pump, then that would explain the low oil pressure.

um as far as i know, oil should not be 'spraying' you at idle.  maybe there is something that is releasing all the pressure up top... which is not good for the rest of the engine.. such as the oil squirters (they require 1.7 bar to open... therefore you are not getting the benefits of piston cooling)

i would definitely get it checked out asap.  wouldn't want to ruin a nicely rebuilt motor!
