Danny's TR7 Blog

The engine strip down started with a good de greasing / oiling. As can be seen the block is absolutly clarted in oil.

The gearbox and starter motor was then removed.
On the left side of the engine there is a drain plug, undo this to drain the remaining water from the block.
The intake manifold was removed without any problems all the bolts and nuts were given a good spray with WD40 first.
The next task was the one I was dreading the most, I have heard of the horror stories that TR7 owners have had while attempting to remove the cylinder head. All the bolts and nuts were soaked with WD40 and I followed the workshop book instructions, before I attempted to undo a stud or bolt I gave it a couple of good knocks with a hammer. Each stud and bolt in turn came out with relative ease in fact I could say the head almost flew off.
the sump was removed to give acess to the big end bearings, I decided the first piston to be removed would be the one with low compression (1-2 bar), the photo shows what I found, two broken rings. Fortunatly the bore and piston was in good condition. I checked the rest of the pistons, rings and big end bearings all seemed to be in quite good condition with only a little wear on the big end shells. The main crank bearings were also in good condition. I decided to rebuild my original engine.
