Hi all , following up from my “rate my plug” post . I changed all the plugs this weekend and did an oil and filter change. I did the rear four plugs from underneath and the front four from the top. Fired her up to find that she is annoyingly on only 7 cylinders . The plug caps are buried under the manifolds and heat shielding and were very tight to get off and on again. I have pulled and re fitted caps a couple of times but still running lumpy. I only had one cap off at a time so not mis fitted lead. Very frustrating as it was running smoother before I touched it 🫣 Back out to have another play after tea. Every time i re start it after trying each lead the manifolds are too hot to get close . Bloody frustrating afternoon. I have tried pulling off leads ad running to see if one makes it worse , i have’nt found one yet that does. I eonder if i have fouled a plug now. Maybe I should run it up the road to see if it clears? I think the caps are in place , i just cant get that nice solid click that tells you they are on properly on some of them . Any suggestions welcome. For those that helped with ideas on “rate my plug” over last couple of days, I found the valve cover bolts went up a bit but cant see a lot of oil around the back of them or the heads. And the sump bolts went up a third of a turn easily. Whether it could be a leaky rear main seal dripping into the bellhousing i dont know . Will keep you posted. Thanks all.
