Cam locking kit needed. And as above there appears to be a tool to stop the liners coming out. But as mine was done on a college heap I didn't bother . . . . Wouldn't have had that available anyways  ::)

Can locking kit from amazon,ebay,local motorfactors ,so long as you dont move pistons after head is of you wont need to worry about the liners,but you do need to measure the height to use correct head gasket,also used the correct coolant which is pink and contains oat.

Although not absolutely essential, a flywheel lock makes life easier.

4x4, my K ran fine on GM red, which isn't OAT. Just ensure all OAT is flushed out

I put in the plugs, but it would not start.
I checked compression. No. 1 - 10 bar
                                      2 -  1 bar
                                      3 -  3 bar
                                      4 - 10 bar
Looks like head gasket to me.

Still getting a bit of water in no. 1

Comments please.
Cylinders 2 & 3 are doing sod all

It should stop the leaks.  A vegan alternative to cracking an egg in the rad.  ;)  :y

With compression that low I'd be wondering if more than just the HG was knackered..

Snap, although its possible the coolant has blown the fire rings between the two cylinders.

I imagined it was a leak between 2 and 3 in the HG. What else might it be?.

Look at a head gasket .... the area around the "holes" that are the cylinders are reinforced - looks like a few layers of "folded metal" .. those circular reinforcements are actually the "fire rings" .. they take the brunt of the forces trying to sneak out between the block and the heads !!

If the burn through at the closest point then the comprsing cylinder is directly connected to an exhausting one ... hence no compression ...

crap description but I HTH  :)

Other options would be rings (but it would have been smoking like a train) or valve seats..

A leak down test with all the plugs out should give you a good idea, along with a wet compression test.  If the leak down test had air coming out of the intake or exhaust then valve seats, if it's coming out of the adjacent spark plug hole then it's the HG gone between cylinders.

Can I buy a flywheel lock, or perhaps make one? Would it go in the starter hole?
