    Oil leaking from spark plug housing

    Hello,

    I've just recently bought my 1987 Toyota Hiace Camper and it has an oil leak. I got it home and gave the engine block a clean and the took it a run to see if i could locate the leak. It appears to be coming from the spark plug housing. I had a look and going by what I have read it could be the spark plug tube seals? I was wondering if anyone could confirm that it is likely to be this? And has changed them before? Name:  A6DB7636-D7B9-410C-ABE3-0842DADE7CFA.jpg

    super easy to replace, theyll often come out with the spark plug(good time to replace), its a square section oring theyre often sold with the valve cover gasket and grommets...these rubber parts get hard fairly quick with the heat of the head...

    Thanks for the reply boogieman. Good to hear that it should be an easy fix. I'm struggling to find any valve cover gasket kits or just the orings themselves here in the UK. I can only seem to get them from Australia on eBay!

    for finding part numbers with your VIN : https://www.toyodiy.com
    ive found parts on amazon with just a part number and been able to order directly from the local dealership so far.

    Re: Oil leaking from spark plug housing

    So I've received my spark plug seals from Australia. I took the spark plugs out and the tubes came out no problem, the old seals were very hard. When I took the tubes out I noticed that the were quite worn at the bottom where the spark plug sits on to it. Would this be causing my oil leak rather than the seals or should this still seal?Name:  IMG_5063.jpg

    ooof those are no good anymore, probably from repated over torquing of the plugs...the lower hole should only be large enough for the plug to pass thru and hold down the whole tube...make sure the rest of the tube is not inside the head

    boogieman thanks once again. Brilliant, just what i was expecting. I'm not sure if i have the correct part number.

    Is this the correct part here?

    11191 22010
