Can you replace the vave stem seals without pulling the head off the motor?Just put a jdm motor in my civic and guess what. It seems to be burning oil. Not to bad I put 3600 miles and only added 1 quart to it.I replaced the other motor it had in it because it was doing the same thing.It was going through much more oil then the new motor but none the less I dont want my car to use any oil.
Its a d15b 89 civic dx hb.
Any info would be appreciated.

 

yes you can replace the valve stem seals without removing the head, but you need an in car valve spring compressor, along with a air compressor with a fitting that threads into the spark plug hole (to keep the chamber pressurized so the valve doesn't fall in). this way is quicker than taking the head off, but you need the equipment... if your not planning to keep the car too long, just thicken up your oil.. saves you money and headaches...

 

Thanks Greekgino for the responce. Yes I plan on keeping this car for a long time It gets excellent fuel mileage and runs great. I put a jdm motor in it and it runs great no problems other then the small amount of oil it uses. NO smoke or oil leaks so I am thinking its the valve stem seals.

 

Does anyone have a detailed write up with pics on how to do this?

 

I have been telling all with oil leaks to change your PCV valve. You do burn alot of oil if it is stuck. Cleaning is not a good idea. Go OEM.

Try this an see.

If it is stuck you build up pressure in the crankcase and blow oil out more. Make sense?

 

Nope no oil leaks. I just changed the oil today and while I was under the car I seen no oil leaks what so ever. All dry underneath.I also changed the pcv valve when I had the motor installed.I can hear the valve moving when I rev up the motor.

 

i dont understand how people give advise on this site... how can u come to a conclusion that the reason for his loss of oil is due to the pcv not functioning, it could be one of a hundred things... dont even get me started on "no starts/emissions/gas mileage" these are all areas where someone with experience diagnosing vehicles should look at... for the sake of people who do not know and come to forums thinking that someone who installed a cold air intake and removed the honda emblem from his front grill, has the exact answer to his unique problem.. please dont send them off to the parts store and make them replace parts that are already good... pay for an hours worth of diagnosis if u arent sure... people are very quick to try to solve problems and seem smart...

Ive been wanting to write this exact thing for years. Thanks for finally expressing what is in my head

 

LoL now thats funny .
Ok so I plan on putting in new valve stem seals. I think they might be hard and brittle and allowing oil to seep through.If I pull the rocker assembly off and put compressed air into the cylinder and pop the springs off the valves. Do I have to readjust the valves when I put the rocker assembly back on?

Yes. This job isnt very difficult with the right tools. I rec. a leakdown tested to pressurize the combustion chamber,a valve keeper remover

and a valve stem seal remover

to pull the seals. Be sure to lube seals when installing them. A 10 mm socket usually will do. Install rockers,adjust valves and your off.

 

how well does that valve keeper remover work?

 

Place it on the retainer,give it a tap with a hammer and due to it being magnetic,it catches the keepers. Installation is a little tricky,but once you do the first one,youll get the hang of it. I always place the keepers in the reatiners,place on top of valve gently and push down. Goes on every time. Some guys try to place keepers on the end of th tool and pray they fall into place,this is how they fail

Heres a good write up on how to remove it and install them. I will be using the rope method and not the air method.

 

PCV valve was the trick car doesn't burn oil and has lost all the little annoying hesitation issues it used to have. Old valve was stopped up pretty bad. Its soo smooth now!
Thanks for all the help!

This is a response I just got. What would cause alot of oil burnage that everyone forgets about.

Just trying to help people save money and try the smaller stuff before a repair shop rob's them of their hard earned money. In my book $10 bucks is worth a try.

 

Smogman always knows....

 

There is an easy way to test the valve seals. Let the car idle for about 10 min. After 10 min. rev the engine. If the valve seals are bad, you will get lots of smoke. Generally valve seals leak just after periods of idle where there is the most vacuum present in the intake.

if you have a long steep hill around you, then drive down it using the engine to brake the car. if it blows smoke during the down hill or right after the bottom then it's usually the valve seals.
i've never heard of letting the car idle for 10 mins.
