Smoker!

Ever heard of oil ports clogging on the head so the oil won't drain down causing oil to seep past seals into cyc. causing it to smoke?

I had a truck with a 5.0 and it was so bad that it was like a jello mold of oil when I took the valve covers off but it didn't smoke. But then again that was probably because oil couldn't get to the valve seals to leak past them so yeah I would Definitly so that is a possibility

Yes, That's caused by not changing the oil often enough or using cheap oils without much detergent in them.

How do I fix that? Will an engine flush work or do I need to clean the ports another way?

The best thing to do would be to pull the heads and have them hot tanked and rebuilt, but tightening up the top end may lead to issues with the bottom end if it has been mistreated like that.


Pull the valve covers and manually remove as much gunk as you possibly can.
Reinstall the valve covers and flush out the engine by adding a quart of engine flush, diesel or kerosene.
Start the engine and let it warm up good and circulate the mixture around, do not rev it hard.
Then shut the engine off and drain out the contaminated oil and remove the oil filter, be careful it will be HOT.
Replace drain plug and use a new oil filter, fill with new oil.
I would change out the oil early the next 2-3 times.
Keep an eye on it and as soon as it goes to black, change it out.
