In late 2015 I purchased a 2008 (ish) Husqvarna LGT2654. I knew of an oil leak, but wanted a winter project and so I took it on.
It starts and drives. Oil leak is not constant, at times it would not leak other times it would leak fairly fast. Tires would go flat in 24 hours due to cracking. One of the tires is beyond repair, but seller had an extra wheel to go with the tractor. The deck stabilizer bar was bent.
When I got it home, I took off the stabilizer bar as it was just getting in the way – i was able to find an exact replacement on Amazon.com
I had to right away pop off the wheel with the damaged tire and replace it with the wheel the seller provided.
The tractor’s general condition was fairly poor as it was kept outside by previous owner. I cleaned it out and gave it some polish so that it wouldn’t look so terrible.
It was time to start the real work to determine the source of the leak. I started my research and shortly after found that Briggs and Stratton VTwin engines have two common reasons for oil leaks. If caught on time, it is a fairly easy fix. However, it seems most people don’t realize they have a problem until they ruin the engine.
The two most common leaks with these engines are: Head gasket and sump gasket.
However, if you choose to do this job, don’t cheap out and get the full gasket kit. I found mine on Amazon listed as Briggs and Stratton 694012 Engine Gasket Kit
All numbers, values and procedures on working with the Briggs and Stratton VTwin 26HP engine can be found in this manual sold on Amazon (or any other place of your choice)
I replaced the first head gasket on the side of the engine that the leak was coming from, however, after pulling out the gasket I knew it was not going to be the cause of my issue as there was no tell-tale burn through the gasket that happens at times.
With the head shield removed, I could now see the problem. The sump gasket had an issue as I could see oil pump out of the engine in a small stream where sump meets the rest of the engine.
I took off the engine (held on by four bolts from the bottom) and drained oil. Took off the sump and there it was… my problem:
You can see that pieces of gasket are missing and broken down. I scraped the old gasket off with a razor window scraper. While the manual calls for a plastic scraper, I found that plastic scraper broke because the gasket was cooked on. You must be extra careful with a razor because engine block is soft and you could damage it and cause additional leaks. In order to make sure I had a tight seal after using the razor, I added RTV high temp gasket maker on both sides of the gasket – while the manual does not call for this, I wanted to be extra sure 🙂

This is a good opportunity to start taking care of that engine: I recommend AMSOIL Signature for all your engines. If you have a favorite oil already, use it. If you do not, I would like you to do your research on best oils and make your own choice.
My four top oils:
NOTE: Make sure the two dots on the gears match for timing. The reason I mention this is sometimes when you take the sump off, the gear could slide up and get out of sync.
