Oil Issue and Questions

cgreiner · 09-20-2008, 08:12 PM

So, the engine was put in with 35k on it, and now has 40k. It had new belts put on when installed so the belts have only 5k on them. They should be fine.

I have now went and scowered over my driveway and see no oil. But, I was about 0.5-.75 quarts low after about 2 months since my last oil change. Now I am also idling at 20 PSI and not 5 or so as before.

It appears that the leak is primarily while driving. Any thoughts?

oil leaks are hard to dignose with out acually looking at it..

there are many many things that can leak besides what i said..
turbo seals can cause oil consumption and not show a leak on drive way...

If you really think its a oil leak and not the engine / turbo USEING oil then you need to clean the bottom of engine.. and then drive and look at were there is fresh oil.. and go from there...

I just got my car back and the valve cover gaskets are leaking (search Oil Pool in the forums to see what the problem becomes). Thats where all my oil was going....

I did the search for you...

I have heard of a product that allows you to add dye to your oil and use a UV light to find the leak. However, I have only seen this for freon leaks. Does this exist for oil leaks ?

Yes, they do have that for oil leaks. You should verify your oil pressure with a trusted mechanical gauge, the one in the car is hardly accurate. 4 psi is the standard oil pressure for idle, and about 10 psi per 1k rpms is considered norm.
