Ok guys,

I put about two quarts over what is recommended for my car (420a Turbo'd), it was oil additives (engine honey and slick 50000). I was ready to go for a ride, hopped in to start it up and it just pushed out a cloud of blue smoke. Mind you I had no smoking or anything before. I immediately drained the oil and put four quarts back into it. Needless to say its smoking like crazy, does not idle, and fouls out spark plugs like crazy. I believe there is still a lot of oil in the cylinders... I was thinking that running it for a little while it would blow out all of the oil... well when I get on it hard it tries to run smooth but at lower rpms acts like its only running on 1 or two cylinders.

The only thing I can think of to do is is take out plugs and clean them off after every drive, is there anything I can do to get this oil out.

The engine is remarkably strong and had no smoking or anything prior to the overfill.

Thanks in advance,

Jason
 
Jason, first change your profile, if you have a 420, you do not have a GSX. Secondly, if you are getting oil in your spark plug reservoirs, your valve cover gasket is probably shot. Thirdly, I don't see how you would be getting so much oil into the cylinders unless your head gasket is shot, or your piston rings are, either one would cause smoking, and also loss of compression, might want to look into doing a compression check.
 
He has already drained the oil out. I would do a compression test to see if you damaged anything. If any oil got in the cylinders it would be burnt out after a few cycles so oil may still get getting in the cylinders. Also put in a fresh set of plugs
 
will do.... I will go to get compression test done, thanks for the help. I will keep you guys updated. I just dont understand how that anything could have done this after an oil over fill.
 
turns out that compression is at 180 across the board, and I found the problem. I cut the fuel pressure regulator vacuum hose that goes to the megasquirt... which caused the car to be flooded with gas.
 
Slick 50 and Motor Honey=two additives that works against each other. Slick stuff to make the moving parts go easier and motor honey to thicken up the oil to prevent oil consumption

Slick 50 was found to be a witches brew - not the greatest stuff in any motor. remember Duralube, another quack oil additive?

Read this FTC report on the junk: QUAKER STATE SUBSIDIARIES SETTLE FTC CHARGES AGAINST SLICK 50

Oil additives is something that no motor needs. Motors weren't built with the stuff to be added in mind.
 
I just used lucas heavy duty stabilizer now.
