Just bought a gsl-se and the guy told me it smoked but I did not see that it smoke this bad. Here is the run down and maybe you can help me. After sitting overnite, I start the car up and it smokes like I just did the MMO treatment to it( Hope you know what that is)..It smokes whitish grey smoke for a minute or so. Then it goes away . When I drive it , it smokes once or twice ( my friend was watching as he drove along side of me. ) The car drives fine . The oil pressue is 3000 at idle , 6000 at driving speed ( 65 mhp) . Now , I did find out that the previous owner had 1-2 quarts too much oil in it!! I immediately changed the oil as I felt that may have been the problem. I will see tomorrow when I start the car up. Anyone have any ideas ?? could I be right that too much oil causes some kind of oil leak somewhere that it cause the car to smoke bad?? What else could it be?? (1) need a tune up?? (2) bad gas???...what do you guys think...like I said , the car runs fine. Could it have something to do with the exhaust..It has fairly new exhaust on the car and the car does seem to smoke when you let off the gas after going 65-70 mhp. any help would be MUCH appreciated....cjf

well, first off, you are misreading your oil pressure gague. its actually 30 psi at idle and 60 psi at 3000rpm or above. if it were 6000, your engine would be in pieces. or there would be a huge mess of oil. having too much oil in the system could cause a little smoke, but my guess would be one of two things. the first being bad oil control seals on one or both of the rotors. that will cause oil to be burnt at start-up and for oil to be burnt when you let off the throttle while driving. the other thing being that the engine is carboned up and in need an atf or mmo treatment. happens if the engine was negtlected or if it hasn't been driven and run in awhile. from your post, it kinda sounds like oil control seals. try the atf or the mmo treatment. it cant hurt.

I all so have the same problem with my 12A and i think its the oil seals all so, if i pull on the choke to much it seams to smoke lots, so i just pull it half way and wait till it warms up a little bit before i take off it dose seam to deapear unless i go over 7000rpm, then i tends to smoke, or if i hold the rpm at 5000 plus for 3 sec

You said the smoke was whitish-grey? Sounds more like a coolant seal problem to me. Is the coolant level in the rad low at all? Oil usually is blueish smoke.

Where are the coolant seals at in a 13b? Rebuild nesc?

thanks for the info. and correction on psi..I did mean 30 psi and 60 psi.... ....any other ideas?? I will definitely review what has been said. I will do the MMO for sure as that is the cheapest way first. Bad oil control seals?? Is that expensive and is it easy to do?? coolant seal problem?? No, the level is not low and it does not over heat but there is some rust in the coolant. I am changing it today or tomorrow.. You think that could be it??? I think the smoke is lite greyish but i will look at it again and let you know... keep up the comments. It does help me ...regards.......-chris-

the coolant seals are rubber seals that go around the water passages on the rotor housing. when they corrode(from not changing your coolant), they corrode usually around the exhaust side and since they are so thin, the exhaust will heat your coolant, resulting in engine overheating. the other possibility there is that you have a pin hole in the seal or worse, depending on coolant usage. with a hole, the coolant will enter the combustion chamber and be burned. the engine will overheat when you run low on coolant. you will see a whiteish smoke and the smoke will be foul smelling. both require a rebuild.

make sure you flush the coolant, dont just change it. the oil control seals dry out and shrink or crack, allowing the oil to be burned. remember, you rotors are filled with oil anyways and since you have an omp, it is normal for the engine to consume up to a quart of oil every 500 miles. that would also depend on driving condition.

mazdaverx713b...thanks for info.....just some commnets. (1) The car does not over heat at all. I am changing the anti-freeze tomorrow. I was not going to do the "flush" but I will now. I don't think I have a coolant problem but time will tell. I am doing the MMO treatment too. will try all the above things ( including a full tune up) and see what happens...thanks....will let ya all know what or what does not work. I may be back with more help.....cjf
