Anyone know of a good way to remove the carbon from the block, i want to clean it up before i take it in to get bored. Its on there pretty thick on the exhaust side.<br /><br />Koltar
carefully chip away at the biggest chunks, then try "spray gasket remover" in a can. Leave it sit for 10 minutes with a good coat, then rinse off at you neighbourhood carwash.....
If your mech shop dosent want to tank it first I would be looking for another one to do my work. Who wants to do that type of work with a dirty block? M
it has rubber hoses on the inside of the block, they run water around the cyllinders.<br />Tanking it would ruin them and so would baking it.<br /><br />Koltar
the rubber hose deflectors come out and go in easy..........if thats all thats holding you back from cold tank cleaner.<br />Use liquid dishsoap as a lubricant to reinstall them.....
Rubber hoses, thermos and such should always be replaced in an overhaul. Most don't amount to much costs but can go a long way. Think of it as you want your motor as close to new as possible.<br /><br />Rob
