21/04/2005 12:22:50   Adam   Hi, can someone elp me out.. got an odd problem with my V4, it runs great and does not smoke... that is when i can get it started!! Once it is running it runs fine forever.. however, if i leave it for a couple of days, when i come to start it it will not fire.. The reason it will not fire is beacuse the plugs are coated in oil?? Anybody know what it might be??? Oil is a nice light brown colour, water is nice and clear. no "cream" anywhere. engine has done 74k from new and it passes MOT's better than any car I have ever had! help!

21/04/2005 16:41:17   Richard   I would go for the valve guides and seals. You can buy a tool that will allow you to remove the valve springs without taking the heads off. You can then replace the seals. This may help things and is a cheap fix, but I would have thought that your guides will be worn too.
Try Burtonpower for the tool.  
21/04/2005 16:45:06   Adam   Thanks for the replies... looks like I've got the weather for it at least!!!I just checked the oil level.. would the fact it is significantly over full of oil have an impact on this?? The only reason I say is because the heads were of and skimmed less than 1000 miles ago. This was with the previous owner.  
21/04/2005 16:58:12   Alistair   Yes! Over-filled could well mean the oil pressure is too high (despite the pressure relief valve in the oil pump that is supposed to help control this), so it could be pushing oil past seals that would otherwise be OK (why this would happen when static I don't know..).

Drain some out & see how it goes before ripping it apart!

If the heads have been skimmed, it could also be like Rich said the other thread about similar problems - if the inlet manifold to head mating surfaces are not square you might get some leakage through there, especially once the compression is relaxed when you switch off????

Might be worth whipping a plug out & (carefully!) putting some strong tissue or a rag into the cylinder with a screwdriver, then pulling out to see if any oil collecting in there?  
21/04/2005 19:56:16   Max   Richard. I never heard of such a tool that enables taking out valve springs without removing the heads. How does it look like??

 
22/04/2005 07:56:37   Richard   It goes in through the plug hole and holds the valve just like any other valve spring compressor.
I dont think over filling with oil will cause such a problem as its more like splash lubrication in the head.
Is it oil or petrol?  
22/04/2005 12:30:01   Richard   Just on a side note. It might be worth checking your valve clearances. If the previous owner reseated the valves they may have recessed a little over the initial run in period. It is advisable to recheck them after a run-in period they should then be ok for a long time.
What plugs are you using?  
26/05/2005 14:26:35   Adam   Problem seems to be solved... Found an hour over the weekend to have a look at the motor.. emptied 5L of oil out of her!!! More than a bit over full. This has fixed 2 problems.. not only the sparks getting covered on oil but also a problem that has ben nagging but not serious where the car will not sit and idle for very long on its own, it always needed a bit of revving every now and then!
