Oil Burning I have a 2001 accent that appaers to need new vavle seals @ 127K (meters) This seems a bit poor but anyway do i need to take the cam out or can i get a spring compressor below it Much thakns for your time and wisdom petros

There is no correlation between the thermostat and burning oil. This explains what causes oil to burn more than normal.

The torque specification for the rocker shafts on the 2001 Hyundai Accent with the 1.5L single overhead cam engine is 18-20 lb-ft. The proper torque sequence is as follows:

1. Tighten the bolts to 8 lb-ft in a crosswise pattern.
2. Increase the torque to 15 lb-ft, again in a crosswise pattern.
3. Finally, tighten the bolts to the full torque of 18-20 lb-ft, again in a crosswise pattern.

Make sure to use a torque wrench and follow the sequence carefully to ensure proper tightening and prevent damage.

There only two possible ways on this, first your valve seals are gone, second your piston rings are gone. The valve rings can be replace without disassembled the head.

If you are sure it has no leaks, the only other possibilities are worn oil rings or valve stem seals. Generally if the oil rings are worn then the compression rings are as well, so get a compression test. If readings are down on spec, which is about 150 psi., add a tablespoon of engine oil to each cylinder in turn through the plug hole. If readings rise, then it is worn rings at fault. If not, then suspect the valve stem seals.

On these engines though, there are several characteristic oil leaks which may be hard to spot, being the cam cover gasket, crank nose seal, and the distributor o-ring seal.

maybe replace vavle seal's they get hard & brittle over mile's. then oil sipps by vavles & burn .

If the valve seal is leaking, the chances are that the valve guides will need to be replaced, maybe not now but soon so you might as well do both. If the valve stems are OK it would pay to reface the valves as well. This will require removing the cylinder head and an engineering works can do the work for you as the seals need to be pressed out and the new ones pressed in again and the head will need to be skimmed.

You must have worn poston rings or worn vavle guide seals causing the accesive oil burning. As for raising your engine idle speed, it can be done by adjusting your idle screw, but it's not recommended. Factory idle is about 700-750 RPM.

black smoke ( burning too much gas)
blue smoke (burning oil)
white smoke ( burning coolant)
hope this helps

The car either has to be leaking oil, or burning it out the exhaust. You should check to see if there is oil on the bottom of the engine. If clean, it can be burning oil cause rings or shot, emisssion system sucking it back through the engine, etc. Your engine should be in good condition since only 55K miles, unless it got overheated or something. Hope this is a place for you to start, Rick

REPLACING THE BELT AND ANY WORN PARTS WILL BE ALL THAT IS NEEDED
