Head gasket

[vc commodore]

It can't hurt buying both metric and imperial spanners/sockets......

From crap memory the inlet manifold bolts are 3/8"

Sweet so ill grab some imperial sockets


As for the head bolts , can I use loctite 567 on the threads and permatex gasket sealant on the underside of the bolt , or does it have to be a actual threadlocker ?

 

[Immortality]

I've used loctite 567 before and seems to work.

Probably just as cheap to buy a new kit than to by six individual sockets. Have a look at Trade Tools they are the cheapest for decent quality sets.

Also my oil has now mixed with coolant , whats the best way to flush it , cheap oil first ?

 

[Immortality]

Do the work then change the oil. Up to you what you use.

 

[losh1971]

I've seen mechanics use a bit of kerosene with new oil warm it while idling for 5 mins and dump it. I'm not saying to do that BTW just what I've observed. I questioned it.

Don't drive it with coolant in the oil as coolant is not good for bearings.

So removed inlet manifold and exhaust manifolds tonight , the inlet manifold bolts were finger tight ?

Going to remove heads in morning, I ordered new rocker bolts but they are still in the post , can I re use the old ones ?

Guaranteed, with those inlet manifold bolts being loose, your problem will be the LIM gaskets rather than a head gasket.....

I wish it was just the inlet , but i checked im down compression in 1 cylinder and loads of exhaust gas in the radiator

I wreckon the lim gaskets were gone and i lost water and when it overheated it cooked the head gasket or worse
