Hi everyone, The condition of my L18 has seemed to be getting worse and worse - blowing more and more clouds of smoke predominantly after a closed throttle (taking off, after coasting down a hill etc). Its now doing it consistently after every coastdown.
However a compression test revealed a consistent 176 psi (at WOT cold) in all cylinders, so I thought it might be the valve seals. Now the weird thing is in our hot Melbourne weather the car runs much much better (runs smoother, more responsive, less harsh). And the really weird thing is in 40+deg weather Saturday, the engine didnt blow any smoke at all, even after coasting down big hills that usually have bellowing clouds pumping out. So the reasons for all this have got me stumped. Something I thought may be a factor was that the atmospheric changes (temp, pressure) has the engine sucking less air for the same amount of fuel ie running richer in the hot weather, therefore the engine was running lean before. I also thought maybe for some reason the engine is sucking blowby in excessively, adversely affecting combustion performance, but how all this relates to better performance and very little smoke in hot weather compared to normal has got me stumped... Any thoughts on this would be greatly appreciated, Andrew --membersozdat------------------------------------------------------- OZDAT Mailing List Please Note:- Send (un)subscribe requests to [EMAIL PROTECTED] Send submissions to [EMAIL PROTECTED] No unauthorised redistribution of this email http://www.ozdat.com/ozdatonline/index.htm http://www.ozdat.com/ozdatonline/listindex.html http://www.mail-archive.com/[email protected]/ ---------------------------------------------------------------------
