My son just bought his first car, a 1994 Celica GT. slow oil leak around valve cover. bought new Felpro gasket to replace. Slightly too big... is there more than one possible size gasket for the 2.2 engine?

Try the valve cover gasket or the cam seal.

did you miss the word how?
how do I replace a VC gasket?
the how is covered in the service manual, FSM and on line everyday
at alldata dot com.
but in short, since time immemorial.
1: unbolt VC
2: scrape off old. using plastic scraper on alum engines.
3: buy new felpro gasket, put it on with sealant if it tells you to do that. (read the docs with gasket set)
4: set back the VC
5: done.

"leaking into the top of the second cylinder on top of the spark plug wire
only this matter !! cure that.

some engines have spark well. are you saying the wells fill with oil?
if yes, you didnt buy a real valve cover sit, try FELPRO that
comes with the well seals , with kit.
skipping is misfire. if the boots get fill of oil, sure it will misfire, how can it not?

i dont know how much that is as i am in the uk.
i would check around and call a couple off garages and see how much they would charge you.

The most common cause of all oil leaks is the valve cover gasket. The oil drips down from there and covers everything. If your valve cover is leaking, replace it first.

Then the second most common leak in the front of the engine is the crankshaft seal. This seal should have been replaced when the timing belt is replaced as you have everything removed to get to it, and the seal is easy to replace. However if it is not replaced at that time then you will have to remove everything again to access it. The seal is 3 or four dollars, but the labor is two to three hours and you should replace the timing belt, idler pulleys, tensioner and water pump when you are in there, as that will all be removed. Hope this help. Good luck :O)

Yes, Drain the cooling system to a level that is lower then the lower rad hose and where it meets the engine at the thermostat housing. Disconnect the cooling fan switch at the housing and squeeze the hose clamp flanges together to remove the radiator hose from the housing.Then remove the retianing nuts from the housing cover. Once removed note the position of the air bleed valve of the old thermostat while in the housing (bleed valve hole is normally on the top /facing up) Pull out thermostat and gasket. Note that the rubber gasket fits over/around the edge of the thermostat. Replace with new thermostat and gasket making sure the air bleed valve is in same position as previous and spring end is directed into the engine. Install the cover and bolts and tighten/torque accordingly. Reattach the hose to fitting and tighten hose clamp and reconnect cooling fan connector to end. Restart engine and allow to warm up sufficiently and check for leaks and heat in cabin compartment. Done. good luck.

Buy the package that come with valves cover gasket and 4 spark plugs tube seals. Its around $10 - $20 and for replace it only remove the pcv valve tube, the sparks plugs cables and ignition coils. Its so easy!! remove the valves cover, only have 10 screws. Try to buy original Plymounth gaskets or Felpro.

Your car is probably burning oil through the piston rings due to wear. The valve cover gasket will show signs of leaking from the space between the valve cover and the head. Remove one of your spark plugs and see if it is black and oily. You can try using a little thicker oil than what you have now or just add a little in as it burns off. Buy a quart of name brand 20w/50 and use that to top off the oil as it burns off. You should notice a difference.

U need to replace the valve cover gasket and the spark plug well seals which come with the new valve cover gasket set, use a FELPRO brand gasket set much cheaper than a factory set and equal or better quality.

What cover?There are two valve covers,maybe this is what you are referring to?Remove the valve covers and replace the old gaskets with new,making sure to NOT leave any of the old gaskets behind.
