Default Tear Down Engine

Hi , hopefully someone can help me i got a 94 ranger xlt , i had a blown head gasket and also i was told my seals are bad due to the fact that 1.white smoke recently started coming out of the tailpipe and lately its was getting worse like i said just to be clear this is white smoke only not blue smoke 2. when i took off the spark plugs i noticed oil on them , so i bought a top side engine rebuild kit meaning head gasket set to also fix my blown head gasket which includes http://www.autozone.com/autozone/cat...questid=194825 , I bought the set but before i do anything i wanted to make sure on what to do as i know about taking the cylinder head off and stuff but when it comes to them saying the seals are bad and thats what making the oil come out , were on the engine is the gasket located for it and what is it called , is it the valve cover gasket or something else , sorry im new to working on this truck and just want to make sure theres no problems , from what ive heard and read it just valve cover gaskets that went bad but like i said i want to make sure

Please if anyone can shed some info on this it would be greatly appreciated , and sorry i wrote alot i just wanted to be as detailed as possible

Default Hello

I would say the valve seals, or piston rings. There the two ways that oil get into the combustion chamber. Valve seals where out and so do the rings. I think changing the seals for the valves is the easiest. You would remove the followers, and compress the springs and remove the keepers and then remove the retainer and spring and then remove the old seal and replace with a new seal. You can also check the valve guides by putting your finger over the valve hole and pulling the valve out and seeing if it makes a poping sound like when you flick your finger out of your mouth.

Now is it on the threads or is the end of the plug it self oily. Also a good way to tell is by a compression test. This should show you if the rings are bad, and the intake valve area will be slighty oily up by the valve if the valve seal is failing. Also you can just look into the spring and see if any valve seals have been pulled up off the seat. Does your engine use oil then. I had a worn out motor that was so bad I burned a quart every week and a half.

Doesnt really use to much oil , as far as the plugs its actually on the thread that goes inside , and i even tested one and replaced the front spark plug with a brand new one because i has a few lyin around and after a few days of driving and took it off and checked it , other then just oil there was some kind of gunk buildup on the end the side with the thread , any clue what that could be , is it possible that if the valve cover is bad that somehow the stuff is gettin sent to the plugs , but i noticed that front one closest to the radiator was the worst plug the only one that had gunk on it the rest just had oil

The valve cover seal won't make a difference at all unless its leaking from the outside down the head and then around the spark plug. I would use autolite plugs only. I have had bad luck with others. The copper ones are really good and no need to spend the extra money on others. Not sure about the gunk, but maybe you have some carbon build up in the front cylinder. I would get some sea foam and squirt it into the throttle body while the engine is running. Use a small amount at a time, and hopefully this can clean some stuff out for you. I have had good success with it myself. you may have some smoke so don't be alarmed, and it will run ruff when you dump it in so just keep the rpms above a thousand, and you should get rid of some carbon build up.

well yeah so far all i have used was autolite , but so now based on what i told you with the oil getting on the thread side of the plug that goes into the engine , would it be the valve seals or something else thats the problem , because currently smoke is coming out of the tailpipe

I wouldn't worry about it. I have seen that on mine too, and I don't have an issue. Its really just a problem when it causes your plugs to fowl, or you have to add oil inbetween oil changes. I would just replace the valve seals cause its easy if your going to do a top end rebuild. Also have a valve job done. Also there is a cool 3M tool that will clean the top of the block and the bottom of the head so you don't have to pay for it. I will post a picture. You can find it a napa and only use the green finger kind reguardless of what they tell you to use.

do a compression test on it. if youre burning oil, you will most likely not have good compression. if the compression is low, squirt some oil into the cylinder through the spark plug hole using a syringe or something else. check the compression again and if the compression goes up then the rings are bad. if the compression is unchanged then it is your valve guides

to check if you valve seals are bad, rev up the engine, if blue smoke comes out when the revs go back down, bad valve seals, or if you got a manual, have someone drive behind you, if blue smoke comes out when you shift, again bad valve seals, i think it is the valve seals, bad rings would be making blue smoke all the time.

So I would also replace the headgasket, cause white smoke is usally a sign of a crack in the headgasket. The tool I post the picture of will clean the block of the residue, and check for pitting and divits. if there are none you shouldn't have to get it surfaced, and a new headgasket comes with a topend rebuild. Use the tool on the head too, and it will also clean off the carbon. You can also clean off the piston tops. just do 1 and 4 then 2 and 3. If they want to much money they have tons of rebuilt 2.3 heads of ebay for like 250.00 shipped last time I checked. just make sure to get the right year, cause there are changes between the years. Good advice on the oil squirt in the cylinder too.

If the head gasket popped... have the headmagnafluxed... no use putting a busted head back on.. before you take it to the machine shop, look, most time you can see the crack, it most likely be around the exh. valve.. also if one combustion chamber is cleaner than the rest, thats a sign of water/coolent getting into the cylinder and "steam cleaning"
