Customer: I just replaced the oil cooler on a c13 and flushed the entire system . The customer ran great back to his house and said that cel and stop engine light both came on twice as he reved up and his oil pressure went down . Any ideas ... I did not change his oil when he was in the shop because he wanted to save money.

He said his oil was lower than it has been after we did his oil cooler in the shop. A silly question I think but should his oil have been changed as well.

Ok will do but I another follow up. Is it possible that the failed oil cooler sludged up the oil bypass valves when it failed . My tech claims that the oil pressure was fine .
Customer
I do know that that on these c13 twin turbos the oil bypass valves in the filter head can have problems .

Thank you for that

What may have and probably happened

is the oil pressure regulators are sticking

they wil free up in time a oil gets hot

Ok I will let my tech know but in your opinion should a fresh oil change help. He just had his unit serviced a month ago but was running a while apparently with the cooler leaking .

Hi Thank you for that

Yes fresh oil would have helped , no coolant in it

coolant is not like water ,where if will boil off

it stays in the engine , this cause a sludge

I hope this helped you

Please remember to rate my answer

as That is the only way I get paid ,

and not the site keeping the total amount
