Blue Smoke on hard acceleration : eBay Guides

Blue Smoke on hard acceleration is due to piston blow-by.  RESTORE will fix this in 500 miles providing the piston rings are not broken.  Check the compression in each cylinder to find out if all cylinders are bad or just one cylinder.  If all cylinders are bad, providing there are no broken rings, RESTORE should fix it in under 500 miles.  If you have one bad cylinder, re-check the compression on that one cylinder, add 200ml of RESTORE oil through the spark plug hole and re-check the compression (called a leak-down compression test).  If the compression is better with the RESTORE oil then RESTORE will fix the problem in that cylinder.  If, however, the compression is the same low reading even with the RESTORE oil then the problem is not worn cylinders or rings, instead it is a burnt valve or valve
