I just replaced my head gasket in my m42, and I used brake cleaner and some purple power to clean the pistons and block of which I'm sure some crept into the oil. I already drained the oil, and I will be changing the new oil out after about 100-200 miles just to have the filter pick up anything I might have missed with the vacuum. Was wondering if people suggested I throw some "engine flush" for the first oil change and any brand recomendations

and it might not hurt to pull the pan and wipe it really clean after your next oil change in a few hundred miles. on the m42 it's easy enough to do. that'll also allow you to see if you have any plastic pieces from your chain guides in there if you've never serviced that area.
