[quote="BigAl"]Hey john, Power is ok, fuel economy is ok, emissions are still a little high, 2 qualified mot testers, who are mechanics have both ruled out the cat and say the car is slightly over fuelling. They said not to bother replacing the cat when I suggested fitting one. I was told to check fuel pressure, I’ll do that on Wednesday, correctly this time and to test the compression. When i was doing the compression test, i was expecting to find the N/S to be different to the O/S, as the N/S belt snapped and bent 2 valves. I had all the valves reground whilst the head was off and replaced the 2 bent ones with second hand ones, as I didn’t want to upset the balance of the engine too much. To have both sides doing the same front compared to rear is confusing. Iain, lol[/quote]

No idea why you would get higher figs on the rear cylinders. <br /> <br />Compression loss can only realy be rings/bores, valve/seat problems, or plug thread damage. Compression gain- not sure really, build up of carbon effectively reducing capacity?? <br /> <br />What's the official recommended fig? Can't really remember as mine was almost 8 years ago- Lee's fig sounds ok. <br /> <br />Why are you testing compression anyway?
