Hi Ruhan

Know the feeling i bought a KZTE couple of weeks ago and have been topping up with a pint of oil per week, no smoking at all no power loss eventually had a stern talk to the garage where i bought it from then took it to the local Toyota agent and they found the rings have gone. The mechanic noticed smoke coming from the dipstick pipe when he checked the oil and when he took the oil cap even worse. They now sorting it out

Ruhan,

I understand that the plugs was taken out with the oil on them before you did a wet compression test??? reason why i say that is because a lot of people do the wet test, fit the plugs and then drive around and then take the plugs out again. Also bear in mind that oil do sometimes manage to get past the seals and rings. This is very prominent in a engine that is driven hard with higher mileage on.

Also oil on the plug does not always mean that the rings have gone. It can be that the valve stem seals are starting to wear and cause oil to bypass..and then leak back into the combustion chamber from the shims/lifters side of the cylinderhead.

I would recommend that you have the vehicle checked out by the dealer (toyota). What oil consumption are you getting on a 1000 km's?

Are you sure it was oil on the white porcelain area of the plug and not carbon?

Mine uses about 500ml of oil on 10,000km

thanks for the replies

it was defenitly oil on the white sections of the plugs

the oil usage was 500ml per 1000 km but it seems to be getting better ... checked tonight after about 700 km and seems to be ok the oil is even clean ....

i know that 500ml per 1000km is within spec of toyota but in the family there are 4 of these and mine is the only one that uses oil...i hate it...

cheers

jaco

wat doen dit???

[pietpetoors]

Ruhan, as dit wel olie op die wit gedeelte van die vonkprop was, is dit nie dalk net die tappet cover gasket wat lek nie. Omdat daardie vonkproppe deur die tappet cover gaan moet hy seker 'n ronde seel aan die onderkant van elke gat he, as daai seel lek gaan die olie mos by die prop area ingaan.

pieter

ek glo dit is 10 teen een wat die probleem is

enige idee wat so gascet sal kos?

[pietpetoors]

Geen idee, maar my duimsuig raaiskoot sal wees dat jy 'n hele head gasket set (wat tappet cover gasket insluit) by Midas gaan kan koop vir minders as wat Toyota jou net vir die tappet cover gasket gaan vra. So bel maar rond en vind eers pryse uit. Jy kan nie fout maak met 'n Payen gasket van enige parte winkel.

Hi julle
Ek het ook daai probleem ...geen rook nie nat plugs nie maar my 2.7 gebruik ook olie, ek kry ook oli aan die bo kant van die plug en nou vermoed ek dat dit beslis die tappet cover gasket moet wees .
Met n vorige diens het een plug selfs vas gesit in die olie wat al hard geword het bo om die plug.

ek hou die posts dop met n valk oog

[pietpetoors]

Ek het nog nooit een van die se tappet covers afgehaal nie, maar dit maak sin dat aan die onderkant van die gat waar die plug in is moet daar 'n ronde seel wees wat hom daar seel. Ek dink die ou 18R corrola se enjin was so gewees en die moet seker dieselle wees.

Dit behoort glad nie moeilik te wees om die gaskets te vervang nie, mens moet net eers uitvind of mense dit los in die hande kan kry.
