Broken tappet

<< < (8/10) > >>

Block the head off with cloth. Centre punch those bolts and drill with a smaller drill. They will come out they are well oiled.  A bit of heat from the drilling will release them. If you can get a reverse drill bit( is there such a thing?) it would be great.
I've never had a problem removing those and I've had a few broken ones.

Bryanj:
You can buy LH drill bits from a decent engineers supplier, but if that don't work get a 6mm helicoil kit to do a proper repair.

Don't forget if you take the head off you really need to do the base gasket as well as its the same nuts that hold it all down

bomber:
Good news, all nuts off and no more broken bits!
A bit hesitant about taking cylinder off, I suppose I should just to check if all rings are still there.
Bad news, valves looks a bit tired, there i so much crap on them, can I get it off? What shall I use?
Cylinders are loose now as well, so I guess have to replace that gasket too...
Is DS Engine gasket set, "Complete Top and Bottom end" alright?
Pictures to follow.

bomber:
What shall I do any suggestions?

Trigger:
That has done a few miles but, you are in now. Check, de-coke, check. See how good the cam chain is why your there. I always use Vesrah gaskets, very good and cheaper than originals.
