Metal sludge after rebuild
Metal sludge in sump after rebuild
Hey i am busy with an xr4i to pit on a aftermarket ecu.
To cut things short: i dropped a stainless ring in my engine. And luckily it went in my sump. So i dropped the sump of my car.
To find some metal sludge in my sump. 3 mm of oil that woud not mix with the rest of the oil.
The engine is rebuild some years ago. About 3/4 years. 2 years ago i pilled it apart again for diffrent alu camshaft gears and head gasket. No metal found!!! i did break the engine in with normal
Oil. No disturbing things found.
Dont know if i replaced the oil back then.
After the 2nd tear down i used the car mainly for short distance. Had some long high speed runs on the autobahn some small burnouts. Nothimg really crazy
Light to mild abuse engine always warm.
1st teardown:
New arp conrod bolts
Gaskets
Crank bearings
Conrod bearings
Piston rings + hone
High flow oil pump
New used crank
2nd tear down
New new camshaft no bearings
New timing gear
Headgasket
As i am busy with the aftermarket ecu. I have let the car sit for about 3/4 months. Last month i cranked the engine with no plugs to see if there was a crank signal. I cranked the car for maybe 5 whole minutesfrom last month to noe (in maybe 50 key turns.
And last i saw there was no oil pressure while cranking.
So i primed the engine and got 4 bar of oil pressure with a electric drill.
Oil pressure on cranking is 3.4 bar somewhere around that.
Is it normal to find metal particels in the oil at this stage? I ve driven it for around 2to 3000 miles since the first teardown.
