Reply To: Engine overheating

Paul,

I understand your reluctance to remove the engine but, in my experience, you will struggle to see, let alone clear, the problem.  I believe the liners will need to come out and that means removing the pistons from the crank.

However, working from on top as you intend, the  most important thing will be to ensure you do not disturb the liners.  They are simply sitting in place in the block and, without the head to restrain them, they are free to move.

Once the head is off, do not turn the engine over unless the four pots have all been clamped down to prevent them being lifted by the pistons.  This can be achieved by clamping it with washers or similar, see this post on the 6 cyl page :

If the silting is as bad as I think it could be, it may initially anchor the sleeves but do not rely on it because once the joint between a liner and the block is disturbed it nearly always results in the need to replace the liner gasket and, if that happens, you will almost certainly have to strip the lot down.
