I have done this job. I'm not sure I would be able to justify the cost unless I did a good deal of the work myself. The parts are cheap and readily available. The issue is getting the engine out and back in plus the rebuild cost. Time for another opinion on the problem. Is the engine hard to start? Rings and blow by would mean lower compression and hard starting. Mark Tamblyn On Nov 21, 2007, at 7:19 PM, [EMAIL PROTECTED] (mailto:[EMAIL PROTECTED]) wrote: List Need advice. My Model 15/5411 Universal is ailing. Several months ago had the exhaust manifold replaced after replacing several freeze plugs (water leak). Soon thereafter the exhaust pipe riser developed a hole and as a result the engine compartment was flooded with exhaust smoke/carbon. The exhaust pipe riser was replaced. Soon thereafter I started smelling exhaust fumes. Bottom line. Mechanic has diagnosed the problem as piston ring failure caused by the engine ingesting the carbon exhaust/carbon. Due to the ring failure I have "blow by", that is, exhaust gases are blown into the crank case and exit the engine via the breather tube, which causes exhaust gases in the cabin. the smell that I have noticed. I am faced with an engine overhaul and some big time boat units. Rings need to be replaced and any other problems caused by the carbon build-up needs to be corrected, i.e. cylinder walls, bearings, etc. Does anyone have any experience with this problem? Any observations and/or suggestions would be appreciated.

Mark Thanks for your reply. I have some ability to tinker, but not to this extent. The engine starts and runs normally. At first I questioned the mechanic's diagnosis. In order to verify the fumes were coming from the breather pipe, I purchased a 6' tube that I attached to the breather pipe and ran it out side the cabin. Then ran the engine under load. There was no smell in the cabin. John Jennings **************************************Check out AOL's list of 2007's hottest products.
