.... o.k.,.. so after talking with Sandy,.. game plan is to rebuild what we have ...as long as its salvageable. there is three o.s. brg. inserts avail. so first step is to send crank out to my go to guy 'jerry'' ,.. and get it inspected. same with cyl. head. so I disassembled & removed the cyl. head assy. getting back to the ''turbo'' question, I;m pretty sure that was the culprit. mainly due to the fact that it is the coolant /cooled type. which is usually more common on the higher H.P. engines, but this one may be more due to the compact /heat environment application. but, anyhow... the old turbo was so destroyed , that the coolant and oil were compromised... and it all ended up in the oil pan. well , we all know that a cup of anti-freeze can ruin all the brgs. in an engine , in a very short amount of time. as well as a concrete floor. .... as so the overhaul begins.....
