| My Bronco rider starts fine, runs fine, cuts fine....but upon turning it off I get some smoke/oil burn from up in the very front of the engine. There seems to be a small oil leak up in the front.
From this brief description, any thoughts/ideas as to what it may be? The gist of posting a question is a hope of seeking a clue as to whether such a symptom is impending doom...ie don't waste the $$ to get it serviced, or likely repairable gasket-type issue etc. in advance...thanks for any/all expertise & thoughts!!! |

| Most likely the valve cover gasket. Engine specs for parts are located on the valve cover if this is a Briggs engine. A Kohler will have a white tag on the shroud. |

| catleys, please post some other info and numbers to go with your otherwise good description. We need to know the specific tractor Model Number and Serial Number in order to view an online manual from MTD. This number is usually found under the seat when seat is tilted up. Some tractors will have that info on a hood decal. Also if you can find numbers on the engine itself, those should also be posted along with the tractor model & serial. Once we know which chassis and which engine you are dealing with we may be able to advise you on your needed course of action. |

| Kohler Courage engine, twin-cam, 535CC, serial # 3811517483. If a valve cover gasket, is it an affordable fix? Thanks for taking the time to respond and offer up some thoughts!! Seriously appreciated? |

| Very affordable fix......even if you have to take it to a pro shop. Of course we lean heavily toward DIY repairs here, but we understand (barely) how some folks prefer to "farm it out". If you are reasonably handy and have a few basic mechanic's tools it can be DIY. If you think you want to try it you need to get to the Kohler web site and download a free copy of the service manual for your engine. |

| mownie...I have downloaded the relevant pages. The visual looks to be right where I seem to have a leak, so while I'm admittedly at the lunatic-fringe of being mechanically inept...I actually think I'm going to give this a shot. I've been inspired to attempt a DIY. Is this as easy as removing the valve cover, replacing the gasket, and re-torqing the valve cover screws in the prescribed sequence and to the prescribed specs? Any gotchas? BTW - LOVED the 'we understand (barely)' comment!!!!! |
|
| Yes. They also have redesigned the cover on these to lessen the re-occurance of another leak. |
|
| Well, some of us here are people who always seem to have some dirt under their fingernails, so we have to remember that not everybody is like us. If you have the correct service manual from Kohler, there are only 2 pages you need to see for changing the valve cover gasket. Page 8.7 will help in removing the valve cover. Page 10.13 will help in putting the cover and new gasket back on the cylinder head. |
