Oil Pressure Super High - Is This An Issue?

Hey,

Have been driving my 26/30 for nearly a year now, and there have never been any oil issues.

Just noticed this morning that even after warm up and the 30k drive to work, the pressure wont drop below 7kg/cm2. Usually starts up at 8 and then after warmed up drops down to 3-4 kg/cm2.

This engine has never been flogegd (redline set at 6800rpm), and is driving on a comfortable 10PSI. Car makes about 310 RWKW on 10PSI.

Just wondering if the oil pressure is genuinely high, will this cause any problems??

I have checked oil, plenty in sump.

negligible blow by from rocker covers. Also no excess in cam covers

Water temp is fine, and oil temps dont seem to be elevated when i check.

If this is an issue, where shold i be looking to fix it up.

Thanks in advance guys

What pump are you running?

The only real issue that could arise is your turbo seals if you havent restricted oil flow to it. If thats all good then dont worry, as the relief valve is inside the engine and too hard to get too to try and adjust. If that is even a problem, could just be your standard ops sender as stated above.

If you really want to be sure, tee in a oil pressure gauge and find out.

Running an N1 , and a GT3582, so when we built the engine, the appropriate restrictor was fitted to the oil feed.

This is a new problem, over the last week - however given taht i dont seem to be consuming any oil, i figure i may just wait until I rebuild the car in 6 months to race.

Thanks for teh help

high oil pressure is your friend - mine does exactly the same & recommended by my tuner & many others that know their stuff!

how else would you expect the oil to enter high tolerance areas such as bearings :ermm:

310rwkw @ 10 psi doesnt really add up

Sorry miss-typed should be 15PSI - Dyno graphs are posted in Hybrid section.

The whole point of the question was - given that my oil pressure has previously sat at 4-6 kg/cm2, was the fact that it is now at 7-8kg/cm2 indicative of a problem, or a faulty OPS.

Popular opinion is taht its not an issue and just a shot OPS.

      If you take the top half of the intake off you can unbolt the flap off the shaft and leave the shaft in there blocking the hole. Then you can remove the little vacuum canister off from under the manifold and get a spare vacuum line to run to the ECU. I can take some photos of it later. Probably best to get the vacuum source to the ECU sorted first though. Mine all worked mint with the base map from the GTT an I've pretty much let the closed loop sort the fueling and took 1 degree out of the whole timing map.

      This IS something you also have to configure in Haltech (or at least I did in the past when going from onboard-to-ECU map sensor and an external MAP sensor in haltech land).

      I'm hoping it's something as simple as the ECU is looking for an external MAP sensor, but he is trying to use the onboard MAP sensor.

      You won't need to do that if your happy to learn to tune it yourself. You 100% do not need to do that. It is not part of the learning process. It's not like driving on track and 'finding the limit by stepping over the limit'. You should not ever accidently blow up an engine and you should have setup the ECU's engine protection to save you from yourself while you are learning anyway. Plenty of us have tuned their own cars, myself included. We still come here for advice/guidance/new ideas etc.  What have you been doing so far to learn how to tune?

      Put the ECU's MAP line in your mouth. Blow as hard as you can. You should be able to see about 10 kPa, maybe 15 kPa positive pressure. Suck on it. You should be able to generate a decent vacuum to about the same level also. Note that this is only ~2 psi either way. If the MAP is reading -5 psi all the time, ignition on, engine running or not, driving around or not, then it is severely f**ked. Also, you SHOULD NOT BE DRIVING IT WITHOUT A LOAD REFERENCE. You will break the engine. Badly.
