Question about 1998 Toyota Celica

Celica ST 1.8 Valve stem seals

I have recently change my head gasket and all 16 valve stem seals. After refitting the head and experiencing a smoking engine, I have endevoured to find a solution. I have investigated some of the old valve stem seals removed and have compared them with new ones. I have found that there are some differences in the hole diameters. The original hole diameters measure 5mm were as the new measure 5.8mm. Also, Toyota used to supply two different seals, a green top for the exhaust and a brown top, but now supply just one, suggesting that there is very little difference?
Can anybody help here?
I am trying to solve a problem and with Toyota wanting £9.38 each, to commit to spending £150.08 on these seals is a little scary.
Kind Regards
Graham

    Dear Toyota Ed,

    I have managed to resolve this issue. It was in fact the valve stem seals, that Northern Components had wrongly supplied and after a lot of enquiries I managed to locate some Ajusa seals part no. 57038300 that include the orinially specification seals, this immediately solved the problem.

    It was the fact that the seal given by Northern Components were from a full head set and they guaranteed they were correct!, Also note that Northern Components have completely refused to give me any compensation what-so-ever. Good company hey!!!!

    Thanks for your comments/suggestion, but I am prety sure that if there had been any damage to the pistons or barrels, I would have said so.

    Kind REgards

When does it smoke? All of the time, or just when you start it? If it smokes all of the time, consider piston rings. If you have lots of smoke when first starting only, valve seals and possibly worn valve guides are the culprit.

Bows white smoke when starting


White smoke means water(antifreeze) is getting into the combustion chamber. A bad intake or head gasket could b the problem but it should smoke all the time. Worn valve stem seals however will cause smoking on initial startup then quit, but the smoke will b light blue. If indeed smoke is white, pull spark plugs one at a time & look for heavy white crust on end of plug, if so that cylinder is getting water in it. Do that to all plugs. Re torquing head or manifold may help but if its high milage almost def need gasket. Heads warp also in that case the head must b milled flat. Valve stem seals can b replaced with head on in some cases by introducing air into cylinder to keep valve from falling into cylinder when keepers are removed. Hope this clears things up a lil.

Thick white smoke on start-up. After engine warms up very little smoke or no smoke at all noticable. could it be the PCV valve?


white smoke indicates a coolant burning problem. most likely a head gasket and when it gets warmed up the expansion of the mating components seals off most of the leak. have a head gasket check done. burning of oil is a bluish colour not white.

Taking off the head off is there a diegram or pic i can use


Blue smoke is oil being burned in the cylinders. It could be valves not seating properly, valve stem seals bad, possibly a head gasket if it blew where an oil passage may let oil in cylinders, or badly worn piston rings.
If you can afford it, have a shop do a leak-down test of each cylinder to pinpoint the problem. Then you may know if you need a new head gasket, or a valve problem fixed when head is off, or new valve stem seals replaced, or if rings are bad requiring engine overhaul.

Suspect valve stem seal caused smoking after being idle, replaced head gasket set and p'rings,t'belt, plugs, oil & air filter as there was no service history at 66,000 miles. fired up fine...


If it only smokes after you crank it up and then stops after it warms up usually that is the valve seals letting oil leak down in the cylinder after you cut it off .

Reseal the valve cover. Don't use a gasket, use RTV sealer for the best results.

1993 TOYOTA TERCEL 1500cc Valve Seals Replaced now smokes much worse


You either have had the wrong valve seals installed, they are physically missing, or the valves are incorrect (too loose in the guides/stem too thin). The rocker arm seals will not contribute to your issue. If it did not have the oil smoke before you took the head off, the issue is with whatever the machine shop did. Valve seals have to fit TIGHT, or oil will go down the valve stem into the intake.
Take the head back to the machine shop & tell them to fix it. For free.
