I just picked up a 99 Accord LX with the F23A4 ULEV engine. It has 120k miles on it. The timing belt and all seals were changed by a reputable shop 2 years ago at 107k miles.

There is an oil leak and I can not determine its origin. It seem to be coming from where the oil dip stick meets the engine. It is either that, or one of the seals under the timing cover is leaking, and it makes it way out from the cover at that point.

Is it possible that the oil dip stick is leaking where it connects to the engine? Is there anything else in that area which could be a possible culprit?

 

Yes, it could be that the o-ring for that dip stick is bad. Unbolt it, pull it straight out, and replace that o-ring. They're cheap from Honda then go from there.

Did they fix the balance shaft seal problem in this year Accord? I know my 94 had a problem with the Balance Shaft seal popping out, and Honda made a fix with a balance shaft seal retainer clip. Does the 99 model Accord need the balance shaft seal retainer clip?

 

Anyone?

 

Okay. I have been chasing down this oil leak for some time now, and my mechanic is at lost. He kept the car for 4 days, driving it around and couldnt find the leak. He did mostly in-town driving. He did not drive on the highway for long periods of time.

I put on new genuine honda dip stick o-ring two times. I also added RTV above the o-ring the most recent time. I thought the problem was fixed, from driving around town. After my wife drive 30 minutes to work and back, I see the oil leak again.

The car only leaks when it is driven for LONG distances, greater than 30 minutes on the highway. It does not leak if I just drive it around town. I have changed the PCV valve. What else could cause excessive oil pressure build up inside the engine? I am thinking somehow, excessive oil pressure build up and gets pushed out only when the car is driven for long periods of time. Does this theory make any sense?

 

I've got a wild *** idea - Send me a PM and we can go from there.

 

make a video of the leak if you can ...if lost again can't figure it out

 

Almost a year later, and my wife's 99 Accord LX ULEV is still leaking. All the parts diagrams I look up, I can not find the OEM honda oil pan gasket. Did the car come with an oil pan gasket?? I can only find aftermarket gaskets. What is the part number? There is no gasket listed on Honda Automotive parts website.

 

With Hondas usually steel oil pan= gasket, aluminum oil pan= no gasket (use RTV instead)

 

They probably want you to use hondabond.

Just pick up a victor reinz or felpro

 

If the balance shift seal is leaking you'll see it at the bottom of timing cover plus I've never seen one leak that didn't blow out completely and **** at least 2.5 qts of oil out.it might be possible the honda bond used to seal the oil pump is old an letting it leak

 

right dirty, there is about 4 seals behind the timing cover that could be the culprit. trying to locate a small leak is going to be hard.

op. did they replace all the seals? do you know for sure? you answered your question in your first post. if its coming from that area, if you want to pay again, have the seals changed again and mating surfaces re-hondabonded. like the oil pump housings etc..

excessive crankcase pressure? I don't know, my theory is however, a leak is a leak .

 

Okay, my mechanic says that it was the balance shaft seal. We replaced it yesterday, so now, I have to watch and see how it holds up. I do have the balance shaft seal retainer. I have been reading that the balance shaft is easy to scratch. Is there any repair possible if the previous repair shop scratched the balance shaft?

 

a repair that would be worth the money, instead of trying to salvage a scratched one, would be to get a good used one from a parts motor.

you would have to weld it, grind it down and then balance it. welding on it may destroy its integrity and Im not even sure if anyone even offers that service.

maybe no rtv was used around the outside of the seal before installation.

hope this sheds some light!

 

How far into the engine do you have to dig to get to the balance shaft? Would it be better replacing the engine if that is the case?

 

[QUOTE=professorman;49364125]How far into the engine do you have to dig to get to the balance shaft? Would it be better replacing the engine if that is the case?[/QUOTE

it would require getting under the timing cover again. and maybe pulling the engine to be able to remove it,
but I wouldn't go as far as replacing the engine for it.

 

How do you get to the actual balance shaft to replace it? Wouldnt that require taking out all the components of the engine, pistons and all until you get down to the balance shaft?

 

nope, just have to remove crankshaft pulley(which is a bitch and had a tool designed just for removing it), d/s engine mount, timing covers, balance shaft belt, timing belt, balance shaft retainer (front) and or gear case (rear).

then you should be able to pull them out.
