hi there, youve helped me out a lot by just watching your videos. right now im working on my late fathers car. my mom gave it to me but it sat in garage for a couple years. anyway, its got a few things wrong with it and youve saved me $Ks. 1 of the things you thought me that was vary valuable information was using lacquer thinner to clean the catalytic converter. it made the car run like new again. but i had an exhaust leak that im thinking had something to do with clogging a little to start with. because im not in great shape anymore and by the time i managed to jack the car up and climb under it to find that leak we had some heavy rains and i would end up driving through some dirty water twice and both times the car would act up and then the check engine light would come on with same code that same converter. so ive used thinner to clean it and it worked fine both time making it 3 times now. ive worked hard all my life until im where i am now and that is in bad shape to point of only living on SS now, so i stay low on cash and i was just wondering if the converter gets dirty again before i can seal the exhaust system is it ok to use the thinner a 4th and if not a 5th time or is there a limited amount of times i can use that miracle fix before it does any harm to the 04 kia amani with under 100K miles on it? sorry so long, thank you
