5 year storage, 6000 mile salvage engine from yard

[rick444]

I got a good motor that was prepped w plenty of oil and spray lubriplate in the cylinder walls.
Seems I poisoned the catalyst for a month. It came back, and the code is now gone.
Details, details, details.

I got a young engine put in after long storage before startup i dosed the sparkplug holes with spray oils for initial startup lube.
Whew, got lots and lots of smoke. I never thought of it but for a month the catalytic convertor threw codes. It recovered and cleaned itself in time.
So, FYI do not have cat connected till the engine settles down.
