You don't replace just the top ring, you do them all

If the cylinders are not bored, it could be no ring replacement
will help

You need to ask that at an engine machine shop, in person

If your doing your own work & did a head gasket & not heads
& valves, your doing a lot of work & not fixing much when
you had the chance

You ask a question no one can answer

You don't say it has 150,000 miles & is worn out

If that is the case, you also bore the motor & do a complete
rebuild & have the shop do all the work but install the short
bock & then you do the head install & the rest

SOURCE: no compression in one cylinder

Timing belt slipped around cam pulley. Take off your timing belt cover and check the position. This would explain misfiring and compression loss. Stretched belt or missing cogs in belt likely culprit.

SOURCE: i just got a good answer for this question below

That carbon build up is bad!Carbon is what a diamond is made from and pieces of it breaking off will decrease the life of your engine.Also the carbon will heat up and cause premature detonation in the combustion chamber.Just wait till he leaves the garage and clean it off before reassembly.
Take care!

SOURCE: Oil coming from head gasket

You replaced the gasket, did you have the head checked? It might have a bow or warp in it. Might need to be shaved. This IS something you do when you pull the head. You will need to pull it again( yes, replace the gasket again) and have it checked. This will probably be the problem. 9 times out of 10, that's it( been doing this too many years). Pay and have it checked. hope this helps, and sorry to make you spend money like this

Hi does anyone know why my 2.4 tdci mk7 transit is hard to start 1st time in the morning once it's started its ok but when I try to start it in the mornings it a pig and when it does start I get blue...


This might help explain the causes and where the fault might lie! You didn't mention the mileage, if high it could be worn valve guides or seals!

Blue smoke is an indication of oil being burnt. The oil can enter the combustion chamber for several reasons.
  • Worn valve guides or seals
  • Wear in power assemblies (ie cylinders, piston rings, ring grooves)
  • Cylinder glaze
  • Piston ring sticking
  • Incorrect grade of oil (eg oil too thin, and migrating past the rings)
  • Fuel dilution in the oil (oil thinned out with diesel)
At cold start, blue smoke is often evident, and can reflect reduced oil control, due to fouling deposits around piston rings or cylinder glaze (which is actually carbon deposited in the machined cylinder crosshatching. These tiny grooves actually hold a film of oil, which in turn completes the seal between the combustion chamber and the oil wetted crankcase). Blue smoke should not be evident at any time, but it is worth noting, that engines with good sound compression can actually burn quite a lot of oil without evidence of blue smoke. Good compression allows oil to burn cleanly, as part of the fuel. It is not good though!

Tip

Restoring Car's Power And Saving Fuel At The Same Time


If your car has
  1. Poor fuel responses
  2. Lost its "power"
  3. Low RPM
  4. Lower top speed
  5. Burns a lot of fuel
Then it could be because of carbon build-ups in your engine's combustion chamber. This is left behind with unburned fuel. It causes poor acceleration, a loss in power, lower top speed, and burns more fuel than it really has too. Not to mention causes smoke belching.

The best way to get rid of that would be to have a carbon ridding solution injected into the combustion chamber. The solution will liquify the carbon and other build-ups, which would then restore the "power" of your car. You'll get better acceleration, higher rpm and top speed, save fuel, etc. have a mechanic do it for you. It's alot cheaper and faster than having the engine overhauled (overhaul could trigger "loose compression").

Leaking and burning engine oil. Black smoke coming from exhaust


Hello Chelsea

There are only three places you can lose oil.

From the valve stems. This burns oil and it will be present in the exhaust. It is the least expensive to fix as only the cylinder head has to come off.

From the piston rings and especially the oil scraper ring, (two compression rings and one oil scraper ring). This requires engine removal, a rebore, new pistons and rings. This also causes oil to be burned in the combustion chamber.

Oil leaks from joints in the external seals to the engine, the sump for example. Also from the oil breather pipe. You can check this by sliding a piece of carboard after you park and check it before you drive next time. Any POOLS of oil signify a leak.

By you saying your oil is black, signifies oil is seeping into the combustion chamber and being partially scraped back.

Check the compression with a tester, and measure against what compression is supposed to be. You can Google this.

I have a honda dx 1987 it starts up blowing blue smoke we replaced the valve seals and gaskets


In order to get the best gas mileage the Honda motors only have one compression ring and a oil control ring on the pistons. If the oil wasn't changed regularlly then it's time for rings after about 120 thousand miles. they all use a little oil because of this one ring system, about a quart in 1000 miles, even when new. When doing your work did you clean the valve cover real good? the cover has the baffles for the oil control of crankcase blowby and as they fill up with carbonized oil the baffles in the valve cover instead of separteing the air and the oil start passing oil into the PCV systema and into the air cleaner and into the air entering the air intake of the engine gets burned in the combustion gases and out the tailpipe.

Just had head gasket done escort van 55 still burning oil


Hello, there are many reasons for an engine to burn oil. Replacing a head gasket will stop leaks in the head, but it is not a cure all. You can have bad compression, bad oil rings, and valve guides that are worn. A new head gasket can fix compression leaks between cylinders and oil and antifreeze leaks.

Overall bad compression means both the oil rings and power rings are worn out. You can have bad oil rings and still run reasonable well if the power rings are okay. The valve guides are the small seals on the stems and with an overhead cam they are in the heart of the engine. Sometimes when the valley of an engine is plugged up, the oil can not return to the crankcase fast enough. The pooling oil is more apt to lay by the valve stem seals and be drawn into the combustion chamber.

Also check the PCV valve which may snorkel up oil into the induction system. Another sign of bad rings is blowby on the vent pipe.

Just had an oil change, but the mechanic tld me that my car is burning oil, how does that get fixed?


An engine will burn oil for several reasons, mostly related to wear. First, the rings on the pistons can wear, allowing oil to get past them into the combustion chamber where it gets burned along with the fuel. Cylinder bores also can wear giving the same net result. Cure is to rebuild the engine.
Your valve guide seals can harden up and allow oil to pass into the chamber or, the guides themselves can wear essentially doing the same thing. This is cheaper to repair than an entire engine rebuild but still quite expensive if done correctly.
A third way to burn oil is often missed. that is worn engine bearings....when the bearings wear, there is more oil being thrown onto the cylinder walls than the oil control rings can handle...that causes the rings to accumulate carbon deposits that cause the rings to get stuck and then pass even more oil into the chamber.That too is an expensive rebuild to do correctly.
If your engine is leaking at all, you need to consider repairing any of those leaks, providing that you aren't using huge quantities of oil and not smoking from the exhaust to any great degree. That will cut your usage down somewhat.Also make sure that any venting system is working properly (pcv etc) pressure buildup in the crankcase can force oil to go where it does not belong, externally and internally.
First thing you need to do is to monitor just how much oil you are really using. If you are using a quart or less in 3,000 miles, you might want to consider using a good synthetic oil and a good additive like lucas engine treatment. That combination will help clear carbon from the rings and soften and restore valve seals.
If you are using far more than that, there is no chemical that will put metal from worn parts back on them. Only cure is a total rebuild or engine replacement. Only you can decide if the car is worth going through that expense to repair.
Hope this helps you understand it better!
Good luck and ask if you don't understand any part of what I said!!!

Changing 10-40 to 20-50 oil


The use of a 20-50 oil will not harm your vehicle,,,neither will the use of lucas additive. BUT, have you determined the reason for excessive oil consumption? (leaks vs burn off) Even what appears to be a small drip can use more oil than you think (ever leave a container under a dripping faucet?) Have you had a compression or leakdown test done on the engine to determine the extent of cylinder/ring wear? You may find that much of the oil consumption is due to dried out valve stem seals (far less expensive than a rebuild) In any case, using a good grade of oil will delay the wear process. Using a poor quality lubricant will accelerate it.
Poor quality lubricants have a high parafin content which forms sludge and are prone to burnoff even in a well running engine. This forms carbon in the ring grooves and causes the rings to stick and lowers compression as well as permitting more oil into the combustion chamber. That's something you don't want or need in a worn engine.

Oil consumption


Bad valve seals
Worn valve guides
Pressurized crankcase (oil pan) due to a clogged PCV valve or breather system
Blow-by from worn piston rings

Bad valve seals: The valves are located in thecylinder head above the combustion chamber. Oil is pumped at 50 to 80 psi of pressure into the top of the head, lubricating the valve-train; the valveshave seals on them to stop the flow of oil down into the engine when the valve is open. If the seals fail, oil is allowed to flow down into the combustion chamber and is burned.
Worn valve guides: The valves are guided by a small cylindrical chamber called a valve guide. These guides wear over time causing eccentricity (or slop); the excess gap allows the flow of oil down the valve stem into the combustion chamber to be burned. What about the valve seal you say? Well, the gap is too great for the seal to stop the oil flow, so down it goes to be burned.
Pressurized crankcase due to clogged PCV or breather system:The car's engine is a giant pump, consequently it must breathe. The PCV (Positive Crankcase Ventilation) system does just this, allows the engine to exhaust the excess pressure build-up (which is a natural phenomenon of the internal combustion engine). Carbon build-up is a by-product of an engine and can build up in the PCV system, clogging the breathing passages. This in turn pressurizes the oil pan and pushes oil up into the fuel delivery system, where it is fed into the engine and burned.
Blow-by from worn piston rings: The pistons in your car's engine have seals around them in the form of rings. These rings do two things:
  1. Seal the combustion chamber so the precious power developed from the firing of the cylinder is not lost.
  2. Provide vital lubrication to the cylinder walls.
When the rings wear out, the pressure from combustion reverses down into the oil pan, pressurizing it and forcing oil into the valve covers, through the breather system, back into the fuel delivery system, and into the engine to be burned.
You may ask yourself, "What can I do to stop this from happening?" Keep your oil and filter changed every 3,000 miles and keep the air filters changed every 12,000 miles!! This will keep sludge and carbon buildup down to a minimum. Understand that you can't stop mechanical wear, but you can slow it down!
