Hi does anyone have any spare head bolt washers I lost 2 when I last did head gasket and I replaced them with copper ones ..... Think that could have caused head to go again ... I'd happlery pay for them  Huh? Or any info where to get 2 from  Smiley Neil

You can buy packets of decent stainless steel washers to fit your head bolts,try B+Q make sure they are the same thickness as your originals,and your fine.
P.S. Copper washers are useless on head bolts because the bolts have to be torqued,copper will just spread,use copper ones where you need a seal such as sump plugs,you can reuse them as long as you ANNEAL em.hold em in a pair of grips on your gas stove flame till red.

Oh so the head bolt (spanner end) is shaped like it has a built in washer? I've never had an ESTI one out.Just went on E/BAY there on there �20.00 a set,here's a pic.
I just typed in estima head bolts,then E/bay came up with these..

Thats right the washers spin on the bolt but don't normally come off
are you sure its not a blockage are you getting steam out the exhaust.
how long before its over pressuring.

Id get these they also do genuine head gaskets you just need to ask.
if It is the case that the washers have caused the problem theres a strong chance that the head would have lifted.

you can check the oil cooler could be cracked there. or there is another place the oil and water could mix, cant remember of the top of my head.
But the use of copper washers does put to reason for the gasket as the head expands with the heat the washers become more crushed even split and would cause the torque to be off set.
you will need to do a full flush and oil change plus your water will need flushed as well

Hi Tony, & cods 68, the head bolt washers do come off the bolts and the pic on ebay is showing the bolts without the washers, the flat bit is to stop the socket from going past the top of the bolt, if you only used 2 copper washers along with the remaining washers then those bolts if torqued proper will have stretched and wont be any good with new washers, if you have already had the head off and reused the bolts its best to get a full new set of bolts as the all stretch when re used Steve

Think 1st port of call is to locate where oil is coming from ... There's hope it's not head   :Smiley
