Re: IML: Oil usage theories

Hi Dan:

You can change the valve seals without pulling the heads if you really need to.

However, if you do pull the heads you can rebuild the heads, install teflon seals and get a good look at the cylinder walls

Have you tried a more viscous oil?  

Things in an engine can change quickly so you should really do a leak down test or at least another compression test to see where you stand now.

Good luck.
