Thought i would try this and see if it eliminated the problem with my smoky Mk2 worth a try for £3 i thought it’s a very thick liquid so i would recommend leaving it in a bowl of hot water to thin it out a bit , following the instructions to the letter i put in my engine and then drove for a few miles, the car at this point wasn’t smoking as the engine was warm and it doesn’t smoke when it’s warm .
parked up at home and left it overnight moment of truth started it in the morning and after about 15 seconds it smoked just as much as before !!! so either my problem is worse than Stop Smoke can fix or it doesn’t work at all apparently it’s supposed to make the seals swell up thus stopping the leakage into the cylinders maybe i might try another bottle or maybe i wont !!
You may have the same issue I had with my Mk1 1.8. I had appalling oil consumption, and eneded up with clouds of white smoke on cold start, though besides that the car drove fine. The problem was with the oil scraper rings, and the only economical solution at the time wa a complete engine replacement. American Miata owners mention a product called Sea Foam that can be used to free up stuck oil rngs, with some success.
yeah i have seen seafoam but it looks even more of a magic beans solution than the smokestop !! i checked the pcv valve as well it was a bit stuck but is fine now with a few blasts of brake cleaner wether that compounded the problem i don’t know
Precisely the same to the letter earlier this year. New engine was the answer. I got lucky and got low miles a real corker from AK Automotive and it’s transformed the car.
