Hi All,

Do any recall ever having a rubber seal / washer at the top of the boot under the cap where the coil pack is to seal it against the Valve Cover?

I came to know about it when ordering new coil packs, but i never have had them.

Recently taking out the packs 3 of them where stuck and i had to tear them out. The shafts had sand and rust in them from the beach trips.

I guess if i had these seals it would of been clean down there. Its probably something worth checking as my tubes are pretty rusty. They are pretty much a oring, but the one in the picture looks like one side is flat.

The Coil packs i got from suzispares didnt have them either, so wondering if they where ever on there or its a recent thing as have never seen them listed before either.

never seen an extra seal on the factory coil packs or non genuine ones, that seal would be to seal the spark plug tube to the rocker cover.

EDIT: suzistore state it's the "SEAL SPARK PLUG TUBE - ORing seal on the rocker cover for where the coil pack plugs in."

The part number listed in the SuziStore link is an O ring that goes between the cam cover and the plug tube - it does not seal the coil pack to the cam cover.

IF the coil pack "lances" are in good condition they will seal to the plug tube, and you can add a smear of dielectric grease to help - look very carefully at the lance and you'll see it has a tiny "vent hole", rotate the lance so the vent hole is shielded by the connector. You can also grease the ceramic insulators of the plugs to reduce corona discharge & flash over, and a smear of the grease inside the end of the lance will reduce the chance of it bonding to the plug, as that is what causes them to tear. Once they are torn moisture gets in.

Thanks, when I took everything off there was no seals between the tube and cam cover. Nothing that looked like that picture.

I also use dielectric grease on the plugs, but thought a bit of grease around the top and bottom could help too.

Here are pics of under the cam / valve / rocker, "things that go up and down and round and round thingy" cover + the cover top and cover bottom.

I guess i can use High Temp Red gasket stuff between the tube and bottom of cover?
The coil pack does have a ruber seal and seems to seal well (but no oring) but dont know why there was bits of sand etc down there so it couldnt of been seald that well so will look at grease, oring or some sealant (i have seen spark tube silicon gasket / sealant yesterday).

The O rings fit in a groove in the cam cover holes - the grooves are visible in your pictures.

If no O rings were fitted, you would have had an oily mess in the coil pack recess because the blowby would have forced oil out - and, if the vehicle is OBDII I would expect a code of some sort relating to the functioning of the PCV system.

I would order the O rings - removing the cam cover with the O rings is a pain in the backside, removing it after you have siliconed it in place is going to be an absolute nightmare.

Your coils have the later style lances - the breather hole is where what looks like a "nick" in the rib - at around 10 O'clock in the picture - rotate the lance so the hole is shielded by either the coil connector or the body of the coil (3 or 9 O'clock)

THanks Fordem, i have seen the vent hole there is a Oring between the plate on the bottom of the cover and the cover on each hole i gather thats them.

They look in tackt and good, It would be a pain in the arse to remove them as the plate is rivited to the Cam cover, i gather its there to stop oil being sucked into the PCV valve.

No need to remove that plate to change them mate. I put new ones on my green GV just a few weeks ago.

Just use a precision screwdriver or similar to lever the old ones out. New ones then drop straight into place.

Great thanks, will give it a shot. Did you purchase Suzuki ones or are they really just O-rings? I have seen differnt colours and makes.

I can get high temp, oil resistant o-rings pretty cheaply and quick, quick being the more important thing, cars been sititng with covers off for a bit to long.

[GeckoXL7]

THis is the kit i should of got, just found it, i just got the gasket

The rubber seals for the rocker nuts are also bit worn out, they apear to be rubber coated washers, obviously to stop overtightening.

on my old nissan i once had they where just the paper ones, which i wont use, will have to find some rubber ones somewhere localy.

[ninjamoses]

I went genuine suzuki mate from suzistore as I was buying a lot of other stuff at the same time. There is nothing special about them though, they really are just a plain o-ring.
And yep - I replaced the valve cover rubber washers also as mine were looking extremely used.

[GeckoXL7]

Thanks, will get some neoprene orings and washers and work something out.

[GeckoXL7]

I looked and poked around the hole with a small screw driver couldnt see any oring and just seemed like all metal. So im

[ninjamoses]

You are looking in the right place yeah? The o-rings are seated in the grooves in the valve covers.
They seal the spark plug tubes on the heads tight against the valve covers (ie. the outside of the plug tube is a tight sealed fit against the inside of the valve cover plug hole).

Even if there are no o-rings there currently you should be able to clearly see the groove they sit in in the valve covers. You can only see them if you've still got the valve covers off the motor.

[GeckoXL7]

Yeah was looking at bottom of covers in each spark plug tube hole. I tried moving what appeared to be about 5mm rubber ring but didnt budge.

I poked around for a while, there was no room for a O-ring from what i could see. Ended up using High temp RTV gasket stuff in the holes and on the rubber cover gasket, Put the cover back on then smoothed it off and cleaned any excess from the coil tube.

Before i put the cover on i checked how tight the tube was, the RTV stuff should seal it well.

Ill get a close up picture of the spark plug tubes on the cover tonight. Hopefully everything is going back on tonight then Engine needs a good oil and coolant flush.
