Intermittant blue smoke

Post by xirdneh »

the car blew the headgasket, it was the water in the cylinders and in the oil type.
replaced the headgasket and car runs great but
it blows blue smoke intermittantly while idleing
when driving it blows blue for a while then its normal for a while
pcv valve works
tried different carburator
compression on all cylinders is good
oil level is good
replaced valve stem seals when headgasket was done
this thing has got me stumped
Love those Tercell 4x4 wagons but they sure suffer from road noise.

make sure you get good crank case ventilation (double check all the system components). A build up of pressure in the crank cause can cause sudden blue smoke that goes away after the pressure is relieved.

my other guess would be valve stem seals, but you say those are new.

i tried to get it to smoke by blocking pcv valve while idleing
then while revving engine but got no smoke
what else could get blocked?
