Oil pressure on Volvo D13 Engine

Next time you deliver go wait at the dealer. With no warranty your kind of up a creek. They will charge you a bunch of money.

 

Crash the truck.

 

Your engine is MAKING OIL!!!!!! <------- I think...lol


I have a 1998 D12 that has a cracked head on between injector # 5 & exhaust valve.

I dump the oil before a trip, then add fresh 25qts of Rotella + 4 Qt Lucas oil and that gets me 1200 miles of run. Thank God I have a pre-emissions that does not have that Oil/Air Separator crap, else all that extra oil would drown out my motor.

The level at 30qts is one inch above min line. After 200 miles, my oil level is ABOVE the MAX line. I have oil coming out my blowby and I'm catching it with a home-made oil catch, and drain twice during the trip.

My truck shows 70psi on fresh oil+lucas, and 30psi after 2000 miles.

It behaves exactly as you described your truck (low oil pressure + too much oil + shutdown message). So far, after I came up with this bandaid solution, it has not acted up again. I'm looking to replace the head soon though.

@wallance

I see you tried to ask a question within the quote. Let me respond (I know you are stressing, so bear with me)

You said:

• "I just change the fresh engine oil.Now oil pressure looks good at 60"
• "Because the shop said my old engine oil looks like water...."

The "watery" oil is exactly what's happening to my oil.

I put 25Qts of Rotella and 4Qts of LUCAS OIL Conditioner. <----- This is to thicken the oil, because it will THIN out once fuel gets into it.

When I do this, my oil pressure stays at 70psi at start-up and is at 60-65psi for the first 500-800 miles (40-45 at cruise). After 1200 miles it starts to hover around 60psi at start-up and last time I tried to push it to 2500 miles, the oil buzzer/shutdown message came on.

I strongly suggest you grab a few gallons of LUCAS OIL from Walmart asap. to slow down the dilution.

 

If cooler is leaking (coolant?) would the oil not be milky???

Oil pressure drop will slow down with LUCAS OIL ....try it. but dump the oil first and put fresh oil+lucas

Remember, the 3 oil filters take 2QTS each or total 6Qts, so account for that when changing oil, and you may want to put less than the full amount required for oil change.

My truck takes 37qts to dipstick max line. I put 30qts (since I know it will rise)
