  1. New to this forum so please excuse if I'm not familiar with all the etiquette as yet. Situation is: 3.4 XK engine last run about 10 years ago. Engine was in satisfactory running condition when last used. Doing a compression test cold, I'm getting 40 - 60 psi on four cylinders and absolutely zilch on the other two. Might there be any suggestions for a logical way to proceed with investigation? Not too worried about details at this stage, more just a general approach. For example, might a reasonable first step be to remove the cam covers and have a look at the valve train? Any suggestions much appreciated.

  2. Interesting. Plugs are out, no fuel in system and, yes, foot on accelerator pedal. I'll certainly try the approaches as suggested above later this week. An extra snippet is that the engine had had its bores long term soaked with CocaCola (not by me). Anyhow, I'll proceed as above. Thanks

  3. Hi Chris and welcome. As the engine has been stood for so long, remove the plugs and put a teaspoon of oil down each. Wait 5 minutes and then spin then engine on the starter for 5 - 10 seconds. Replace the plugs and retest the compression, if still the same then you start dismantling.
