Howdy, more leaks for sure, seems like sealing surfaces must be really
clean, flat etc. for the synthetic to stay where you want it. Lately, I've
been running mobil 1 at15% with conventional in my truck, just cause when
the Pig needs oil, I've got mobil1 in the garage (stocked up at a sale, for
the race car), and no conventional, so I'll dump that in. dont notice any
problems, minor oil seeps, and the traditional chevy valve guide burn on
startup......as soon as I get the rest of the tooling for cylinder heads,
I'll rebuild them...with real guides in the heads...instead of the cast
iron.....
