Question about 1990 Toyota Cressida

1 Answer

Melted spark plug wire

My 1990 Cressida is leaking oil pretty bad, but I just keep putting oil in it. One time I forgot & the car started to not sound right, so I stopped & got oil it was still sounding funny so I pressed the gas a few time then the sound went away. I got home because it started the sound again. When I putted in the drive way & shut it off it was smoking & smelled like rubber. I opened the hood & there was a sizzle sound & some smoke. I let it set all night . When out in the am & I found that the last spark pulg wire was meltted & the spark pulg was filled with liquid. Can anyone tell me whats going on?

You did not say if you were overheated,also what liquid and what is meant by spark plug filled with liquid, if plug was removed from block! (antifreeze?) Check oil and if water in it you more then likely have a blown head gasket. Hot engine is what most likely caused burnt wire. They make sealers that are put in radiators to repair leaks if cost is a problem and you are comfortable using them, and if not, have head gasket replaced which can be quite costly. Mechanic can determine cause with a compression test. Other things you would be wise to consider if installing new head gasket would be changing water pump,timing belt and crankshaft seal as while as the other belts that need changing.Of course this would depend on whether you planned on keeping the vehicle and if it was worth it. You can talk with a mechanic about using a sealer if this is the problem. I know of no other liquid it could be other then antifreeze.Oil is unlikely. P.S You might want to find out where the oil leak is and correct it before you do more damage!

If you had a head gasket leak then there would be higher oil pressure but I think you would notice other signs of problems. Air and oil are typically sucked into the carburetor or air intake from the top of the valve cover. This is the Positive Crankcase Ventilation (PCV) Valve. You could try changing this valve. They are cheap and it is pretty easy to do yourself. In Honda's they can have problems leaking oil from this point and if yours is clogged for some reason, that may help (not sure).

As far as blowing a spark plug out, that is a pretty big problem. Immense pressure has to happen for the threads to fail, unless the spark plug wasn't screwed in all the way. I would say there is a mechanical problem in your engine somewhere. Either timing is off slightly or a valve isn't working correctly, or there is something in the cylinder that hit against the spark plug.

How did they repair the spark plug problem?

In my humble oppinion this is on your mechanic.There is no reason why a properly done job should leak that amount of oil.If those bolts are backing off they have either not got the right torque spec or they have over torqued the bolts and stripped the threads which is why they keep coming loose.If this is what has happened no amount of gaskets or locktite in the world is going to fix this.In addition did the car overheat because of the original head gasket. If so your head may be warped allowing oil to seep out.Try having the head decked or find another one from the wreckers.Regardless your mechanic should make this right ,I know I would! Good Luck

I CAN tell you that just cleaning out the plug wells is a good idea so no crud gets in the cylinders when plug is pulled. The center piece you speak of is not understood. As for the gasket sealer, yes, it's a good idea to use Black RTV on the head surface after cleaning and to stick the gasket to the valve cover.

1990 Honda Accord DX 5 speed no power/2 cylinders not firing? far as the oil on them it is possible it is only the spark plug tube seals located on the inside of the valve cover,in fact if you can remember when you took the old plug wires off the boots of a couple propably had oil on as far as the real problem I would recommend checking the timing belt it is possible it jumped time,its pretty simple just remove the valve cover(gonna replace the seals anyways)and top timing cover.roll the engine around and look for the cam and crank marks.if you need anymore suggestions or help let me know have a good day DB
