Hi All,

I'm new to the site and have been reading a lot of the post. There is such a wealth of information on here and I look forward to learning from all of you. I have several questions that I would like some help with. I bought a 99 300FW and the body is in great shape; just minor scraps and scratches. The engine is clean except for an oil leak at the top of the right rear crankcase. Tonite I pulled the dipstick while it was idling and noticed that there was what I suspect to be blow-by coming out. The engine runs great and doesn't smoke at all. It has plenty of power and doesn't hesitate when you accelerate. I tried checking the compression but don't have the right size adapter. What could be my problem with the blow-by and will it hurt it to ride it. I down loaded a Honda 95-2000 service manual from this site. Is this manual all I need or is there a better one.

Thanks for any help that you all can give.

The only thing that I know of that would cause blowby is worn rings. I would try to get an adapter for the compression tester and test the compression. If it's just a small amount of blowby, it's probably OK, but if it's pushing oil out the crankcase vent tube, it's a problem. It should be OK to ride it, but just keep an eye on your oil level.

Thanks Helmut for the advice.

I made an adapter for my compression tester and it is reading 180 lbs. every time. Is 180 lbs. about average for 99 that has never had anything done to it? I did not see where any oil had been coming from the crankcase vent tubes so I'm assuming its probably alright for now. Thanks for the help.

According to the service manual, the compression should be 178-206 PSI. It is still within specs and no oil is blowing out the crankcase vent, so it should be OK.
