Only way is to remove head and have the valve and valve seat ground. Best to do the lot as all the valves and seats will be in poor condition. no easy fix

Testimonial: "could i just pull one off the same car and slap it in with out ajusting any thing? is there any way to tell if there good before u put them on.? "

    Yes you can but for the adjustment statement. You will have to loosen off all the adjustments on the cam shaft tappets followers first before fitting head. You first will have to get the no 1 cylinder on top dead center for valve timing next you fit the head. turn the cam shaft over ( making sure that no valves move) until the cam lobes on no 1 cylinder are in a position so that a bit of movement one way will move the inlet valve open and a bit of movement will start to close the exhaust valve . This is known as valve overlap.When you have achieved this the valve timing is correct. Reset valve clearences as as pre specs

I have a 2006 Sebring with a 4 cly it has no compression in cylinder 1 it has only 15 lbs of presser but it doesn't smoke


possible problems, is your radiator low, if so you can be pushing your compression out a blown head gasket into the cooling system forcing your antifreeze out, if this is not happening then, if you have a burnt valve on the exhaust or intake valve, or bent valve, or broken valve spring not letting the valve open all the way, broken piston ring, collapsed lifter if it has hydraulic lifters, a lot of the sebrings had problems with the tentioner going bad for the timming chain, looseing oil pressure inturn affecting the valves to open correctly causeing no compression, im not sure if you have a hydraulic tensioner on a four cylinder but its worth looking into. I had a car I worked on long ago for a guy, no compression on one cylinder, I pulled the head and found that he had a hole burned through the piston caused by a leaking fuel injector, over a period of time it burned through and melted, you could put your finger in it.

2002 VW Passat GLX. Burnt oil smell from engine when I hit a bump


I had this problem with my passat... the valve cover gasket is slightly leaking. If you take the big plastic piece off the top of the motor (4 plastic fake screws you just have to twist) you can see along the edge of the valve cover if there is oil or not. Mine wasn't bad, but was doing the same thing you describe. Here is a write up on how to do it... really easy (http://www.taligentx.com/passat/maintenance/valvecovergasket/) or you can get a Chilton manual which will show you how to do lots of things yourself, usually $30-$40 for the book.

Dead cylinder....timming is right, getting fuel, spark is fine...compression test shows all cylinders are the same, good...the car only runs on 2 cylinders instead of 3...plugs and wires are new...


cant happen, you missed something, if you have spark, fuel and compression the cylinder will hit, go check again, when doing the compression test kill the spark and lock the throttle wide open. most common thing we see on the 1.0L 3cylinder is burnt valves most common cause is the wrong motor oil the valve lifters can not release the oil back threw the bleader hole if you use to heavey a motor oil, we see owners change the oil and use 10W-30 or 10W-40 and usely within 5000 miles the valves will burn, if you want to use the heaver oil then you need to replace the lifters with an updated part number that has the abilty to use the heaver oil.

I am looking to buy a 1997 Blazer.He says it has a misfire in the # six cylinder.What is causing it.Thanks for the help


The easy thing would be a bad plug or wire. The hard thing is a burned or stuck valve. Check the wire to see if there is a spark there. If so, take the plug out to see if it is fouled, if it is clean or replace the plug. None of the above, check the compression in that cylinder. Take all the plugs out, hold a compression gage in reach plug holes. Crank the engine, get three compression readings from each hole. All cylinders should be with 15 lbs. of each other. If there is no compression to speak of in #6, most likely a burned valve. I suspect the valve. If the owner tells you about a miss and hasn't fixed easy things, its probably not the easy stuff. Easiest is just ask if it has a burned valve. ALWAYS ask these question when buying a used car. Most people won't lie about problems they know about. And it is against the law in most states to falsely misrepresent anything you are selling.

Oil sending unit and low pressure sensor replaced oil black in 300 miles smells burnt


I suggest having the compression checked. This is easy to do either by yourself by purchasing a compression tester (less than $50) or professionally. If compression is low in one or more cylinders, then the hot combustion gases are entering the oil pan and burning the oil.

If compression is OK, then check the oil pressure. Again this can be done by yourself or professionally. If it is OK, then the question becomes was there a period where it was not changed for a long time? If so, it may just be that you need to change the oil a couple of times to clean out the sludge. There are additives to help clean out the sludge.

Good luck, Jim

2001 mitsubishi montero limited light on service engine soon 110000 milege burning smell from engine oil ok transmission oil ok coolant ok


look hard around your valve cover or your spark plugs holes especially #3 and #5. i found mine on 3 and 5 spark plugs. oil sometimes drip down to hot eng and smell like burn oil. possibility your valve cover that seal your spark plug hole is worn out and leak around the valve cover and straight down to hot area. replacing valve cover gasket is not easy and if you take it shop will cost you over $1000.00 because of intake manifold and a lots of hardwares to remove. shop around before you take it to the shop. if you do it your self with a friend make sure you take picture for every lines ,bolts sensor plugs and so on you remove. also may as well tune up or change your spark plugs. good luck

#2 cylinde r head bad. how to repair low compression


First thing you need to do is determine why the compression in that cylinder is low. Four possible causes are 1. blown head gasket 2.bad valve(s) in the head 3. broken compression ring, piston ring land or burned piston. 4. rounded camshaft lobes
One other possibility is a fuel washed cylinder (from leaking injector)
You are going to have to remove that cylinder head and do a thorough internal inspection, possibly involving oil pan and piston removal.
Once the cause has been found you can proceed to make an appropriate repair. Or if the damage is beyond your ability, replace the engine with a used or new one.
There is no quick easy fix to restore compression.

Combo diesel engine blows blue smoke from only one cylinder,disconnected electric on each cylinder but smoked only on the same cylinder. Could it be the head gasket,leak from oil passage way. Should i try...


Blue smoke means that the cylinder is burning oil with gas/diesel. White smoke means that the engine is cold and excess fuel is being burnt. It means that the cylinder is having worn out rings.They need a change. Also check the engine oil level as well. It may be going low gradually.

Why would my 96 honda civic be burning oil


Is it burning it or leaking it? If it is burning it then it could be caused from worn out valve seals or valve guides or worn out or cracked piston rings. The engine will have to be torn down to fix a problem like this. You may try using a product like motor honey or lucal oil stabalizer to help slow down the oil burning. There is no easy fix for a problem like this unfortunately
