ticking turned to loud knock oil pressure drop
I have had this truck 1 week now. It has 140k on it and yesterday is seems like it lost a rod bearing or turbo. I have put a about 500 miles total on it. 100 miles ago I put an Edge 15500 race tuner with a dpf delete on it.
I thought everything was running fine it had a slight ticking noise like a noisey lifter (thought is was the typical 6.4 tick). While cruising on the freeway yesterday the ticking turned into a knocking, power loss, and the low oil pressure light coming on for about 45 seconds then went off. I didn't dare get on it more. No smoke, no check engine lights and no engine codes etc...
starting up and idling the engine sounds normal. It revs very sluggish. If I disconnect the charge tube from the intercooler its revs fast (normal). While idling the low oil pressure light will come on for about 5 seconds every minute or so.
Hoping it was a broken rocker arm I pulled the valve covers and there was nothing wrong. Both turbos have some slight shaft play. They high pressure turbo has more and am wondering if the exh. wheel is hitting the housing as it tries to build boost.
Anyone have any ideas? Any way to check rod bearings without getting too deep in it. Any help would be greatly appreciated.
