Blown valve gasket seal

Blew the seal, replaced seal, plugs and wires, as everything was covered with Oil/water. After replacement there was gas/h2o mixed coming out of exhaust pipe. After all parts were replaced, tried to start, acted like it was going to crank but seems as though "no spark". Is there a sensor that needs reset after the engine shuts down from the initial problem?? Please help

Are you talking about the valve cover gasket? There should not be water in your head, just oil in and around the cams...

How do you know there was gas/h20 coming out of the exhaust after the replacement if the car woudln't start (I'm assuming you are talking about vapor)?! Make sure your battery has enough charge to start the car--if it has been sitting for a few days and you have something as small as an amp led light glowing, it can drain the battery.

It sounds like you have a headgasket leaking coolant into your oil, more than just the valve cover gasket.

Plug gap?

Everything reconnected?

There isn't water in the head. When the initial breakdown happened, it was on the interstate, total loss of power, water, and oil spraying out, as the car over heated. There was no water in with the oil, which I am told that is a very good thing.

When you try and turn the car over there was smoke, and dripping out of the exhaust, when I smelled, it was dilluted fuel.

I tried to jump it with another car, seemed to have a bit more power, but not enough to turn over. Almost like it isn't getting enough spark somewhere

Thank you

When you say "overheated", how far did the temp needle go?

Have you done a compression test?

Temperature guage went all the way over, car lost all power and died. Had it towed back. Haven't done a compression test, this may sound stupid, but what exactly does that involve?

You may be looking at a head gasket if the temp got that high...possibly more.

A compression test is generally done when the car warmed up, by pulling the plugs, connect ing a tester, adn cranking the engine over about 4 turns. Then, read the gauge on the comp tester.

A mechanic would be a good idea at this point if you aren't comfortable with this sort of thing.

I would say a compression test is something anyone can do. No need to dish out 80 bucks for something that simple.

Well, it really takes 2 people and a warm motor to do properly.

It was just a suggestion. :)

Yea, any bonehead can do a compression test. Unless...he gets a deep socket that is too wide...stuck in the top of the cylinder...:shakesheadinshameandwalksoffofcliff: :grinno:

Lol, don't laugh at me, just pull a spark plug WITH A NARROW ENOUGH SOCKET, screw in the compression tester in its place, and give the engine a good 4 turns like Lando says. If you aren't getting a reading you're comfortable with, take it to a trusted mechanic to test it for you to double check your work.

If you have good compression (not sure what vehicle you are driving, but on the 4g63 turbo engine, I believe 142 is the serviceable limit), your head gasket is probably okay. If it is on the low end, you may have a leak or hole somewhere...if your HG is really blown you will get barely any compression.

Replacing a valve cover gasket, even if done improperly, should not prevent your car from running, nor should it cause fuel to trickle out of your exhaust. Maybe you flooded the engine trying to start it, and that's why fuel is coming out the exhaust pipe?
