Dave, thanks for that info and I like your old spanner seal remover; I'll make one out of many of my old spanners.
As my car was a company one before I bought it, I think all the issues like inlet gasket had been resolved. Just by the way; The cylinder head bolts were tight and I have a set of quailty impact sockets including a 14mm for those bolts...essential to remove them with a good extension bar. Also lifting the head off the gasket, I found that very, very gentle leverage under the thermostat housing, and the head lifted easily. As I work by myself, I jury rigged a simple pulley system to gently lift the head out; I shall need that again to replace it without damage to the gasket. I also found it easier, with the head lifted an inch up and moved forward towards the radiator, it is much easier to remove the screws and bolts holding various brackets etc from the back of the block. For the future, I'm going to change those Torx screws there for standard Hex...they only need to be nipped up. Thanks for the advice. Garth. |

I suspect the head is a bit weighty so good thinking using the block & tackle/pulley system. Don't forget to clean the threads in the head-bolts (and lightly oil them) and also the block where they screw in, some engines need new head bolts each time, i'm not sure on the B6304 if that is the case or not. Torx or socket head doesn't make any difference as long as they do the job.

Yes Dave, the 6304 head bolts are stretched to tighten in a very specific order, and so a new set is required; they are not that expensive.

The simple reason one doesn`t put the water in before starting is to make sure the engine starts and does not misfire due to water seeping past a faulty head gasket or if the mechanic has not torqued the bolts properly or in fact anything to do with head gasket replacement including didn't get the head skimmed??? Air in the coolant system is a completely different operation to take care of.
