Spark plug seals?

[ChrisLeeBoost]

Is there any tutorials on removing these and installing new ones lads because the tubes are fairly deep so I'm at a loss at the moment ! Seems that cylinder 3 has a bit of oil around the plug and I wanna change the seals and see if it cures the misfire!

[akyakapotter]

seals are in the cam cover pop them out pop new ones in easy job

[ChrisLeeBoost]

Ahhhh I see thanks mate that's probably the only way there's oil getting into my plug tube is it? I've compression tested the engine got good results across all 4 so there's no ring damage or piston damage, unless it's the valve guides but i doubt it is to be honest!

Bumping this up how the hell do people actually get spark plug seals out of the cam cover, they always seem stuck in

I used a heatgun first, then used an allen key through the spark plug hole and give it gentle hits with a rubber mallet so the old seal falls out, works ;) then put a little oil around the new ones and press them in using the old one a cylindrical object like a piece of pipe and go at it again with the mallet, don't push them in too far!!!

I pushed seals in bottom, I think that way those are ment to be installed? I hammereder old ones out with screwdriver...

[EP70-PT]

No, they're not meant to be bottomed, you can't remove them later...

Have to change rocker cover then next time, hopefully don't leak :/ What kind of cap there should be, 1mm or 2mm?

[EP70-PT]

They have to be flush with the hole, hard to explain without showing xD

Okay, I maybe know what You mean, same line as where the sealtube edge is

That's a great way of explaining it

Thanks mate 👍🏻

You can burn the old seals with the heatgun, no probs you welcome mate

[ChrisLeeBoost]

Is it possible that one of these seals leaking could be causing a slight misfire every now and then?

[MR-2]

Water causes misrife so oil can also do that.

When my seals were bad,crankcase pressure would leak through it and push my ht lead off the spark plug, maybe that??

Have a set ordered from Toyota but won't be in till next week would some gasket sealer stop the oil seeping in til I get the new seals ?

any solid screwdriver pops them right out

A few years ago Colin mate I couldn't get the hang on it, I tryed a flat head screwdriver, but it just kept ripping through the seal is there a way of doing it?

[5e colin]

ya from the top when cover is of put the screwdriver on the lip of the seal an a tap and out they come

[patman]

Thanks Colin mate will keep that tip for the future 👍🏻

That's why an allen key is better because of it's L shape, it won't rip through the seal
