The small bore hoses on the oil cooler need to be correct ......I found any kind of flex hoses would develop a kink and shut off coolant flow.

Yes ,dont try to remove anything stuck down.............on powerboats ,using sikaflex between skeg and glass hull would result in a big piece broken out of the hull when the prop hit something.

Large clearances generally indicate cams ground with quietening ramps .

Five different kinds of zinc coating..........hot dip ,arcspray ,inorganic zinc ,epoxy zinc ,zinc paint ...............effective in that order.

Seen Gardner rockers broken by turning the valve spring cap one turn too many onto the valve ..........so thats one thing can go wrong.

Dirty water will quickly kill the pump and valves in your washer ......in fact ,its a good idea to put a water filter on the hose intake of a washer ,as even mains water contains abrasive particles like sand.

Laser cleaning uses the same principle as flame spalling .....rust doesnt conduct heat ,and becomes white hot almost instaneously ,turning into a powder,the larger scabs exploding off ............rust is a water bound compound , this is why sealing rust doesnt stop the rust ,it simply changes the chemical process slightly........but it does hide the rust for a while ,until scabs form under the coating ,cracking it off.
