changing spark plugs on Mivec question

[Wolla]

Today I went to check my spark plugs for the first time since I got the car (1.8 mivec lancer) and pulled out the that rubber fitting that goes over the plug and to my surprise oil was dripping off of it like crazy! What is oil doing up there?

Sorry if this question may seem stupid but I have never seen oil in that area when checking spark plugs. I put the plug back in and the car started up and ran fine but I decided to check back here with the experts to find out if that is normal and exactly how do I get these spark plugs out? ahhahaaha.

Thanks

1.8?

Don't you mean 1.6?

Anyway, usually there is a seal that goes on top the shaft the plug slides into... (plug seals)

When they begin to harden they will leak oil.

[Wolla]

Thanks for the response, let me see if I understand where you coming from; the spark plug is recessed inside a tube and there is oil seal around this tube preventing oil from inside the rocker/cam shaft cover getting into this tube?
If this seal is worn does that mean that oil will gain access to the tube and the spark plug cavity when the engine is running? Or will this oil leak out only when you remove the spark plug leads and asscociated tubes?

Any advice on replacing these seals?

Thanks again for the help.

[MISHI]

You can only access the seals by removing the cover...

The cylinder head hold the splug shafts and at the top of those shafts hold the plug seals. As the car runs the hot oil will seep through the hardened seals and go into the cavity...

Thanks again for the quick reply along with the diagram, its all starting to make sense. Will let you know how the repairs go.

Is that your car drifting broad side around that corner? Well done!!

[MISHI]

nah... just a pic I found on the net

[southside crew]

you have the correct plug tool for this eng right?

The 1.8 part.. I know alot of mivec owners who are convinced that their car is 1.8.. when I tried explaining.. I gave up and said ok ok.. 1.8 then.. lol..

[Wolla]

I have to double check the plug socket I have, when I saw the oil I just freaked out and put that rubber fitting back on. hahaha Did noteven attempt to remove a plug, was concerned the car might not even start. ahahaha, really never seen anything like that. I am definately no expert mechanic but I have checked plugs on previous cars before and that sight of oil in that area was completely new to me ahaha.

Well the guy I bought it from explained to me that it was a hybrid with the 1.8 4g92 block with the mivec head. If you dont mind please explain to me why it is not or may not be a 1.8?

please dont get me wrong I am not trying to fight down that it is a 1.8, just trying to learn as much as possible about the car. I am new to having a car with any slight bit of performance so anything I can learn the better! ahaha

Thansk Again

[southside crew]

4G92 = 1.6
4G93 = 1.8

if he said it was a 4G93 block with the MIVEC head.. I would Agree 100 %..it was 1.8

but the 4g92 block well it's 1.6...

( did you buy this car from down Penal side by chance?)

SouthSide Crew is correct the seal get hard and leak oil. i changes my seals just yesterday 20 min job (for non Mechanic).

Question south Side do the coil pack for the regular ( Non Mivec) work with the mivec. I bought the car in April and now doing some work on it as i had problems finding the right Plug tool ( Slim.. Sorry Very Slim/Bonny 5/8 Plug tool). i found that the Rods are broken from the coil pack and well i need to replace them. wondered if you can get the rods alone as the Coil pack is still good. Simpson Motors doesn't have in stock and was looking to get some second hand ones. so nee dto know if regular 4g92 will work?

[trinibajan34]

where did you find your plug tool cause i have to change my plugs and the standard 5/8 dont fit ,if u know any place in san juan that would be great too.

[SCHOLARS]

the normal plug tool and ah grinder and u good to go trinibajan34. grind down the exterior

[trinibajan34]

so no one in trinidad has that plug socket for sale? that is de only alternative ?
(the normal plug tool and ah grinder and u good ) then i should get to work

[Wolla]

Alright, you guys were absolutely right, those old seals were hard like rock!! Got some new rubber seals and they went on easy, simple fix.

But now my socket to remove the spark plugs does not fit! I have not gone looking yet but does anyone know where I can find the socket that will fit this? (dont really want to start grinding the existing socket hahaha)

One more question, I thought I would change the cam cover seal one time, are these hard to get for mivec?

[MISHI]

I doubt. The 4G91 should be the same...

What size is your socket?

[QuickPc's]

to all the people that can't figure out how to get their mivec plugs out use this simple step by step guide to acquire the tool that would help you out.

1. find someone with a local cs2/cs3 lancer
2. talk to them
3. push dem aside
4. open thier trunk like if yuh own th car
5. move di carpet in di trunk
6. take out the tool bag dey get with th car
7. take their plug spanner and claim it as if it's yours
8. run really fast
9. never look back

that's what i did...

OR.

1. talk to the person
2. just ask them to borrow it
3. return it when you're done

nb... grinding yuh 5/8 not goin to help cause inside the plug shaft has 2 impressions and if yuh 5/8 anythin bigger than 3/4mm on each side it not goin to fit so yuh need to find ah real good machine shop if yuh goin down dah road...

4g18 plug spanner is th same as th mivec...

[trinibajan34]
