This should explain everything:
thanks you..and I’ll update what I find later… right now, I go ahead replace all 4 spark plugs and PCV.
HOW CAN YOU TELL IF YOUR CAR BURN OIL? ERIC EXPLAIN IF YOU HAVE DEPOSITE AROUND THE ELECTROS, THEN ITS SIGN OF
burn oil. burn oil means i have a bad valve seal? my all 4 spark plugs have deposite around the electro of spark plugs.is the deposit means I have burn oil? a bad seal?
please comment…
Deposits on the plug is one sign, smoke out the exhaust is another. If you have to add oil between oil changes, but you don’t see any obvious signs of external oil leaks would be another.
Yes the deposits on the plugs as I showed in the Civic engine video would indicate that the engine is burning oil, a DRY brown crust on the electrode will indicate the engine is burning oil, this could be the result of valve seals as you suggest but it’s more likely in my experience that the piston rings are worn out which would require an engine overhaul or replacement to correct.
