oil with spark plugs don't mix

[Bill UK]

Room Temperature Vulcanising (RTV). Silicon Sealant or I would recommend this product if you can get it in the US. Link it has the consistency of maple syrup and never dries, recommended by vintage car builders developed for Rolls-Royce.

Thanks
is it a problem that has to fixed immediately?

Its a permatex silicon sealer for oil gaskets and water hoses.

Oil in the spark plugs leads to misfires, destroyed spark wires and if hardened, impossible to remove plugs.

Not to mention the tar that will develop over time. Should take care it.

Are you saying oil on one side of plugs, or both? I have 89 supra and doing same, but covered in oil on both sides. The problem is oil plug washers??? How is it getting to both sides of plug and all over coils? thanks.

I have done mine and all you need to do is to remove all of the parts like you was going to change your plugs out and take a 14mm hex socket and remove the hex bolt put the gasket with the RTV on both sides of the gasket and place back in; be careful not to tighten it too much or you'll crack the gasket. Or you'll have to repeat the process. Also, make sure to clean out your spark plug galley from all the oil and replace your plugs with new ones and check your plug wires and replace and or clean off as needed.

You want to check to see if they are blown n look like they need to be replaced...but if they are covered in oil most likely they have fawled out and need to be replaced if not your going to have poor performance and gas mileage.

Plat tip plugs can not be cleaned - standard ones can but not recommended. Replace them

If oil on Both sides meaning tips - could be when they were removed they were contaminated from top oil – that’s what happened on mine. If tips are dark and burned with lots of deposits then probably leaking valve seals or bad rings
