Hole in piston
#20
Thanks all for your replies and suggestions, the engine should be pulled down by end of week, I will take some more pictures and post.

The spark plugs were correct and all the same, B5hs, I don’t believe the head gasket was the problem, it looked good. The exhaust valve appeared to have something under it, I believed it to be aluminium from the piston, could have been something else. Not sure about the manifold gasket, will need to check this. I will check the distributor for wear and bent shaft, great tip.

When the engine was running it was very smooth, even at 45mph, no noise, also idled quietly and smoothly.

Thanks again and I will let you know when the engine is apart.

Colin
