but he stated white ....blue would be oil
I think it might residual from the gaskets before you changed the out. If it is it will go away.
Coolant levels have stayed the same ever since I replaced the intake manifold gaskets but I've had to add a quart of oil after driving about 100 miles. I had a friend drive my truck while I followed him in his truck and the smoke is definitely bluish and smells like burnt oil. I'm thinking it's something to do with the valves, possibly the seals or maybe one is stuck open because of all the sludge and crap that I cleaned out while doing the intake gaskets? It only smokes at start up and hard acceleration, so I dunno .
could run an engine flush thru it then put in fresh oil
Oil level was close to a quart low again so I threw in some Lucas oil stabilizer just to see what happens, couldn't really make anything worse at this point so I'll let you know what happens. I'm pretty sure the valve seals are shot so I'll start checking up on those. Would y'all recommend one type over others, like material wise?
You might want to run a compression test on that motor. 100 miles to a quart is a lot of oil use. When my valve stem seals were shot I didnt use a quart in 1000 miles.
I would want to know what the compression is.
Some people do Seafoam treatment on engines gunked up with sludge and carbon. Google and you will see how its done but I doubt it will correct your problems.
is there smoke coming from the oil fill cap when hot? might put an old style breather cap on it, pvc working?
