A redo of the previous message
Well back to square one, it runs but still smokes. So how do I drain the oil breather hose that you had previously talked about?

KISS · Apr 29, 2009, 06:24 PM

Did you actually get a chance to smell the old oil?

As far as I know, the oil breathers are not repairable.

But, you may try soaking it in a solvent such as Superclean. Pep Boys and Wallmart.

There are probably a few screws that hold it to the engine.

We did chat a bit about compression testers. Here are some examples of one. Compression Tester : 2CarPros Store, Diagnostic Tools and More...

They consist of a stepped spark plug male fitting and "O" ring seals. They are also equipped with a release button.
Think of it check valve, vent valve and a pressure gauge.

Any auto store should have one.

So I buy this compression tester and do what with it. Where does it connect to?

I think 21 and KISS are off tonight. I am not being a smart guy but are you sure you want to try this repair if you aren't sure how to do a compression check? The tester screws into the spark plug hole if its threaded, if no threads then you hold the rubber fitting tight into the spark plug hole and then crank the engine.

The old oil may have had a hint of gas, but I have a major head cold right now.

bsblstud · Apr 29, 2009, 07:26 PM

That is where I was thinking but wanted to make sure, just in case I purchased this and could not get in touch with anyone.

Get a good nights sleep and KISS will be back tomorrow and likely 21 too. We are all here everyday unless I actual get a call back to work.

See you all tomorrow. Don't want to miss this one for sure, can't wait to see where the compression checker goes into the compression area. Happy night to all...

bsblstud. Take care of that cold so instead of smelling the rosess need to smell the oil...

Instructions are usually with the tool.

1. remove all plugs
2. insert gauge into a spark plug hole
3. Crank a few times. Because of the check valve, the pressure gets larger at every cycle, but it won't increase indefinitely.
4. Note reading
5. vent compression tester (sometimes you may have to repeat test)
6. remove it

Do the other cylinder.

Compare readings.

If one cylinder is low. Add oil in spark plug hole. Repeat test.

21boat · Apr 29, 2009, 09:23 PM

Side note: if there is a bad valve seat the test may be false positive for low pressure.

If one cylinder is a lot lower then the other look at the plug you took out of that cylinder and see if it looks oily and wet. Bingo...

I posted a spark plug visual chart here. A plug can tell you a lot of how the combustion chamber is firing and ring ware.

Spark Plugs

No# 1 and 2 on the chart is all about rings and oil..
