I have a 190 xt series 3 I was pulling disc today, and all at once the enginge started blowing smoke at the cranckcase vent tube. Seconds later loud squeaking noise came from engine. Shut it off came back couple hours later started no problem idled fine, eased into throttle and took off. power was fine, then loud squeaking came back. I shut it off. Oil level is correct oil looked fine, I feel I have a issue in piston or ring, etc. If it is a bad ring or piston what is my best option a rebuild, used motor or does anyone have any suggestions. I appreciate any help I can get |

You will have to take it apart first to find out what happened and go from there. If possible, I would rebuild the engine that you have. Buying a used engine is a crapshoot - you could have the same problem 6 months down the road. With a rebuilt engine, you will know what you have - many years of trouble free performance ahead. ------------- '49 G, '54 WD45, '55 CA, '56 WD45D, '57 WD45, '58 D14, '59 D14, '60 D14, '63 D15D, '66 D15II, '66 D21II, '67 D17IV, '67 D17IVD, '67 190XTD, '73 620, '76 185, '77 175, '84 8030, '85 6080 |

Yep, I'm with Mack, squeak or chirping noise usually means spun bearing. ------------- 59 D17 gas nf, 66 XT 190, 69 220. |
