smoke at start up

[begoniafrone]

My 93 LE has smoked from the exhaust on a cold start since I bought it at 114k.
25k later it's starting to get a little worse, as in after 3-4 hours of sitting vs. 12 hours. it only takes 30 seconds to burn off. It's white and sometimes thick.. summer or winter. The longer it sits, the worse it will be.
Looking under the valve cover when we did the timing belt.. It had some major sludge.. I scraped it all out and cleaned it up at 120k now I'm near 140k and I checked again under there.. It looks clean still.
noticed valve 3 and 4 had oil around the plug.. and am just wondering where to start. I'm wondering if this engine is going to go soon? It ran on low oil due to the oil pump gasket for a long time.. I would check it 2x a week. thats fixed 10k ago

It does have a high pitch vrrrrrr when listening.. any good advice is appreciated..

Blue smoke? As in oil consumption??

Most oil consumptions are from worn valve stem seals. However, it could also be piston rings. Squirting oil during compression test can help determine the cause.I'd use Fel Pro's stem seals.

Running low on oil could also cause rod/main bearings to wear, among other things. But you can check/replace the stem seals without opening up the engine, as in the case of rings and bearings.

Are you using coolant? If so you may have a blown head gasket. However, the so call blue smoke is mostly white with a bluish tint. So look again.

thanks for the reply,
I also found another related thread. http://www.toyotanation.com/forum/showthread.php?t=267963[/URL]
also a link in there on a similar how to scenario..
I will keep an eye on my fluid levels and figure it out, also the compression test Is probably a good idea for me.
